00:03:47,990 --> 00:03:46,140 astrobiology what was the moment that 96 00:03:49,369 --> 00:03:48,000 sparked your interest in the career that 97 00:03:51,830 --> 00:03:49,379 you've pursued 98 00:03:54,170 --> 00:03:51,840 yeah no that's a really great question 99 00:03:56,030 --> 00:03:54,180 um I guess I grew up in a really bushy 100 00:03:57,649 --> 00:03:56,040 area next to a national park so I was 101 00:03:59,750 --> 00:03:57,659 always getting outside and I loved the 102 00:04:01,729 --> 00:03:59,760 environment I also love figuring out how 103 00:04:03,170 --> 00:04:01,739 it all came together and you know the 104 00:04:04,550 --> 00:04:03,180 chemistry of the water and what makes 105 00:04:05,930 --> 00:04:04,560 all the trees grow 106 00:04:08,330 --> 00:04:05,940 um I went and I did you know 107 00:04:09,649 --> 00:04:08,340 environmental science at Uni and I kind 108 00:04:12,289 --> 00:04:09,659 of found myself falling into 109 00:04:13,850 --> 00:04:12,299 astrobiology research really looking at 110 00:04:15,470 --> 00:04:13,860 these fossils out in the desert of 111 00:04:17,330 --> 00:04:15,480 Australia which we'll talk about in a 112 00:04:19,129 --> 00:04:17,340 bit and I did my research I did my 113 00:04:20,509 --> 00:04:19,139 honors in this space and I went up to 114 00:04:23,150 --> 00:04:20,519 the dark and India and it was all 115 00:04:24,770 --> 00:04:23,160 exciting but I wasn't really sold on 116 00:04:27,290 --> 00:04:24,780 astrobiology I was like oh that's a bit 117 00:04:29,270 --> 00:04:27,300 of fun but whatever but it was actually 118 00:04:31,189 --> 00:04:29,280 um when I was hanging out with Sadaf 119 00:04:32,870 --> 00:04:31,199 Pandi who um some of your viewers may 120 00:04:35,150 --> 00:04:32,880 know set up the 121 00:04:38,150 --> 00:04:35,160 um Indian astrology Research Center and 122 00:04:40,249 --> 00:04:38,160 now at JPL and we'll add a you know a 123 00:04:42,350 --> 00:04:40,259 talk in Sydney about Mars and 124 00:04:44,030 --> 00:04:42,360 astrobiology and afterwards at the pub 125 00:04:46,189 --> 00:04:44,040 there was just so many interested people 126 00:04:48,230 --> 00:04:46,199 asking us questions you know and people 127 00:04:50,210 --> 00:04:48,240 who had no idea what astrobiology was 128 00:04:52,070 --> 00:04:50,220 but had some really really you know 129 00:04:54,350 --> 00:04:52,080 interesting insightful ideas about 130 00:04:55,490 --> 00:04:54,360 Enceladus or they talk to an alien the 131 00:04:56,810 --> 00:04:55,500 other week and wanted to ask us 132 00:04:58,430 --> 00:04:56,820 questions you know and I feel like it 133 00:05:00,110 --> 00:04:58,440 was just very 134 00:05:01,909 --> 00:05:00,120 um beautiful human Connection in 135 00:05:03,830 --> 00:05:01,919 astrobiology that really links us all 136 00:05:05,749 --> 00:05:03,840 together about figuring out where we're 137 00:05:07,490 --> 00:05:05,759 from figuring out if this other you know 138 00:05:09,170 --> 00:05:07,500 life out there and that's what 139 00:05:11,270 --> 00:05:09,180 captivated me and I think as you can 140 00:05:13,249 --> 00:05:11,280 tell I

--> 00:05:17,460 people um outside of science through 144 00:05:21,590 --> 00:05:19,380 astrobiology and that's what hooked me 145 00:05:23,510 --> 00:05:21,600 in so yeah now I'm a PhD student I'm 146 00:05:25,790 --> 00:05:23,520 doing all the things and yeah it's great 147 00:05:27,469 --> 00:05:25,800 I love that yeah I've always you know 148 00:05:30,050 --> 00:05:27,479 I've always thought myself like my best 149 00:05:31,850 --> 00:05:30,060 science hasn't been in the laboratory or 150 00:05:33,950 --> 00:05:31,860 even out in the field it's been around a 151 00:05:35,629 --> 00:05:33,960 campfire talking with people about 152 00:05:38,029 --> 00:05:35,639 science and about the cool things that 153 00:05:39,469 --> 00:05:38,039 we know so I love that but one thing I I 154 00:05:40,969 --> 00:05:39,479 do want to touch back on there you 155 00:05:42,590 --> 00:05:40,979 mentioned the dark 156 00:05:43,969 --> 00:05:42,600 um so maybe our audience or some of the 157 00:05:45,590 --> 00:05:43,979 folks watching right now are watching 158 00:05:47,150 --> 00:05:45,600 later on the YouTube recording aren't 159 00:05:48,950 --> 00:05:47,160 really aware of what ladakh is would you 160 00:05:52,550 --> 00:05:48,960 mind explaining what you did in ladakh 161 00:05:54,350 --> 00:05:52,560 in 26 scene yeah definitely so um I was 162 00:05:56,270 --> 00:05:54,360 very lucky as an honors student so in 163 00:05:57,770 --> 00:05:56,280 Australia we kind of do a mini Masters 164 00:06:01,189 --> 00:05:57,780 called honors it's just like a year of 165 00:06:02,810 --> 00:06:01,199 research after your undergrad and um I 166 00:06:04,909 --> 00:06:02,820 was very lucky that we were studying 167 00:06:06,710 --> 00:06:04,919 ancient hot springs that were preserved 168 00:06:09,469 --> 00:06:06,720 in the fossils in the pilbara so that's 169 00:06:11,330 --> 00:06:09,479 in Western Australia this amazing Arcane 170 00:06:13,370 --> 00:06:11,340 so it's three and a half billion years 171 00:06:15,830 --> 00:06:13,380 old like this super super super old 172 00:06:17,930 --> 00:06:15,840 fossils in Australia and we found there 173 00:06:20,510 --> 00:06:17,940 was Boron like the element Boron Rich 174 00:06:22,370 --> 00:06:20,520 Hot Springs preserved in those rocks and 175 00:06:24,890 --> 00:06:22,380 then it just so happened that the NASA 176 00:06:27,110 --> 00:06:24,900 space were down program which is a field 177 00:06:29,090 --> 00:06:27,120 trip of scientists and Educators were 178 00:06:30,110 --> 00:06:29,100 just going to Le dark so that's this 179 00:06:32,570 --> 00:06:30,120 north 180 00:06:34,909 --> 00:06:32,580 um North ish of India up in the 181 00:06:36,890 --> 00:06:34,919 Himalayas this beautiful high desert 182 00:06:39,050 --> 00:06:36,900 with sand dunes and places and all this 183 00:06:41,029 --> 00:06:39,060 amazing stuff but there's a boron Rich 184 00:06:43,129 --> 00:06:41,039 hot spring there and they'll go in there 185 00:06:45,890 --> 00:06:43,139 to investigate it and my supervisor was 186 00:06:48,350 --> 00:06:45,900 like mate just tag on like I'll pay you 187 00:06:50,749 -->

leaders 190 00:06:57,110 --> 00:06:54,539 at Blue Marble and a few other amazing 191 00:06:59,689 --> 00:06:57,120 NASA scientists um and I was collecting 192 00:07:01,730 --> 00:06:59,699 water samples and understanding what you 193 00:07:03,350 --> 00:07:01,740 need to concentrate elements in a hot 194 00:07:05,809 --> 00:07:03,360 spring what do you need happening 195 00:07:07,850 --> 00:07:05,819 underground to get all of boron or 196 00:07:10,610 --> 00:07:07,860 calcium whatever you want to make life 197 00:07:12,110 --> 00:07:10,620 bubbling up to the surface and um yeah 198

still so much 204 00:07:24,890 --> 00:07:22,740 really awesome research going on in 205 00:07:26,930 --> 00:07:24,900 ladakh Siddharth founding as part of 206 00:07:28,730 --> 00:07:26,940 that and so for those interested there 207 00:07:30,350 --> 00:07:28,740 is Cosmic Adventures there they're 208 00:07:32,029 --> 00:07:30,360 taking people out to explore the field 209 00:07:33,830 --> 00:07:32,039 site in ladakh it's worth checking out 210 00:07:36,409 --> 00:07:33,840 if you're interested in exploring that 211 00:07:37,909 --> 00:07:36,419 part of India before the show you 212 00:07:39,409 --> 00:07:37,919 mentioned to me 213 00:07:41,450 --> 00:07:39,419 um an interesting I'd say uh 214 00:07:43,909 --> 00:07:41,460 serendipitous experience you have with 215 00:07:46,249 --> 00:07:43,919 Martin Van granenbank I've done you know 216 00:07:47,330 --> 00:07:46,259 I've read amas with Martin before he's a 217 00:07:50,089 --> 00:07:47,340 really well known scientist in 218 00:07:51,950 --> 00:07:50,099 astrobiology but you had an interesting 219 00:07:53,029 --> 00:07:51,960 experience where you offered for you to 220 00:07:55,010 --> 00:07:53,039 come along 221 00:07:56,990 --> 00:07:55,020 um into the bush and I wonder if you can 222 00:07:58,430 --> 00:07:57,000 explain that experience to our guests or 223 00:08:00,110 --> 00:07:58,440 to our to our audience 224 00:08:01,070 --> 00:08:00,120 no definitely 225 00:08:02,629 --> 00:08:01,080 um so 226 00:08:04,129 --> 00:08:02,639 um this is when I was an undergrad so I 227 00:08:05,689 --> 00:08:04,139 was in my like second year of University 228 00:08:07,309 --> 00:08:05,699 and 229 00:08:08,689 --> 00:08:07,319 um Martin was just like some distant 230 00:08:10,309 --> 00:08:08,699 Professor you know and as an undergrad 231 00:08:12,110 --> 00:08:10,319 you hardly get much chance to talk to 232 00:08:14,330 --> 00:08:12,120 them but he knew I was interested in 233 00:08:16,309 --> 00:08:14,340 camping he knew I really enjoyed um 234 00:08:17,809 --> 00:08:16,319 driving around the desert in big you 235 00:08:20,749 --> 00:08:17,819 know banged up four wheel drives and 236 00:08:23,270 --> 00:08:20,759 Utes and stuff and um he had a master's 237 00:08:24,770 --> 00:08:23,280 student who was mapping all of these 238 00:08:27,350 --> 00:08:24,780 um hydrothermal veins so they almost 239 00:08:29,270 --> 00:08:27,360 looked like brick walls cutting through 240 00:08:31,369 --> 00:08:29,280 the desert where they're kind of deep 241 00:08:33,649 --> 00:08:31,379 underground veins that used to fill up 242 00:08:35,089 --> 00:08:33,659 with fluids and then solidify and it 243 00:08:37,550 --> 00:08:35,099 kind of crisscrossed the landscape and 244 00:08:39,529 --> 00:08:37,560 as a landscape of Roads a bit more 245 00:08:40,730 --> 00:08:39,539 resistant to getting eroded away and 246 00:08:43,610 --> 00:08:40,740 weathering so you get these kind of 247 00:08:45,710 --> 00:08:43,620 lines crossing everywhere and he had his 248 00:08:47,570 --> 00:08:45,720 master student from Iran it's amazing 249 00:08:49,130 --> 00:08:47,580 guy called Sahand who was driving around 250 00:08:50,630 --> 00:08:49,140 mapping all these veins and what way 251 00:08:52,730 --> 00:08:50,640 they went but he didn't have an 252 00:08:54,050 --> 00:08:52,740 Australian driver's license so he was 253 00:08:55,730 --> 00:08:54,060 like hey Luke do you want you know when 254 00:08:57,710 --> 00:08:55,740 all expenses paid for a trip to the 255 00:08:59,570 --> 00:08:57,720 desert and basically be this guy's 256 00:09:01,670 --> 00:08:59,580 chauffeur dry driving around in the 257 00:09:03,650 --> 00:09:01,680 desert so for a month when I was you 258 00:09:06,170 --> 00:09:03,660 know 20 years old I would drive this guy 259 00:09:07,730 --> 00:09:06,180 out and it was beautiful because he had 260 00:09:09,650 --> 00:09:07,740 to walk to all of these vents you know 261 00:09:10,850 --> 00:09:09,660 and a big Arc and mapped them all and 262 00:09:12,050 --> 00:09:10,860 I'll just like drop them out there in 263 00:09:14,090 --> 00:09:12,060 the morning and pick him up from the 264 00:09:15,710 --> 00:09:14,100 other side of the afternoon and I had a 265 00:09:17,930 --> 00:09:15,720 hammock and I had a book and I said it's 266 00:09:19,430 --> 00:09:17,940 lovely you know Adventure in the desert 267 00:09:21,290 --> 00:09:19,440 um hanging out you know watching this 268 00:09:23,570 --> 00:09:21,300 guy and making sure he's walking between 269 00:09:24,650 --> 00:09:23,580 these mountains and um yeah I fell in 270 00:09:26,690 --> 00:09:24,660 love with the desert it was really 271 00:09:27,829 --> 00:09:26,700 beautiful yeah I love it yeah and like 272 00:09:29,449 --> 00:09:27,839 our audience they're often you know they 273 00:09:31,670 --> 00:09:29,459 want to know like how do I become an 274 00:09:32,870 --> 00:09:31,680 astrobiologist and sometimes it's those 275 00:09:34,009 --> 00:09:32,880 little things just you know someone 276 00:09:36,050 --> 00:09:34,019 comes up to you hey do you want to drive 277 00:09:37,310 --> 00:09:36,060 a car around the Outback for a month 278 00:09:39,170 --> 00:09:37,320 there's a little things that can happen 279 00:09:40,430 --> 00:09:39,180 that can can build not just your 280 00:09:43,130 --> 00:09:40,440 community and the people that you know 281 00:09:44,750 --> 00:09:43,140 but also your your life experiences oh 282 00:09:46,550 --> 00:09:44,760 definitely yeah and I think that's the 283 00:09:48,530 --> 00:09:46,560 beautiful thing where I you know got 284 00:09:51,050 --> 00:09:48,540 into astrobiology and done some amazing 285 00:09:53,389 --> 00:09:51,060 stuff especially out into pilbra before 286 00:09:54,949 --> 00:09:53,399 I love camping and I love you know 287 00:09:56,509 --> 00:09:54,959 forward driving and these kind of things 288 00:09:58,250 --> 00:09:56,519 that I never would have thought would 289 00:10:00,110 --> 00:09:58,260 have um you know helped me get a career 290 00:10:01,730 --> 00:10:00,120 in science so yeah I think just your 291 00:10:04,670 --> 00:10:01,740 passions can take you in really weird 292 00:10:05,870 --> 00:10:04,680 and wacky ways very cool so let's talk 293 00:10:07,730 --> 00:10:05,880 about where your passions have taken you 294 00:10:09,590 --> 00:10:07,740 then in your research from undergrad 295 00:10:11,210 --> 00:10:09,600 getting interested in Hot Springs a 296 00:10:12,470 --> 00:10:11,220 little bit in the environment and kind 297 00:10:13,910 --> 00:10:12,480 of transitioning more into you know 298 00:10:15,590 --> 00:10:13,920 environmental geochemistry and kind of 299 00:10:17,030 --> 00:10:15,600 working more in this realm 300 00:10:18,290 --> 00:10:17,040 um tell us a bit about your graduate 301 00:10:20,630 --> 00:10:18,300 research and what's really been 302 00:10:22,370 --> 00:10:20,640 propelling you these last few years yeah 303 00:10:23,389 --> 00:10:22,380 no definitely um so I've got this 304 00:10:25,009 --> 00:10:23,399 amazing 305 00:10:27,769 --> 00:10:25,019 um group of people that are supporting 306 00:10:29,509 --> 00:10:27,779 my PhD research so I have 307 00:10:31,970 --> 00:10:29,519 um people at University of California so 308 00:10:33,530 --> 00:10:31,980 Dave Dima and Bruce damer who are really 309 00:10:34,670 --> 00:10:33,540 looking at the chemistry of these Hot 310 00:10:36,410 --> 00:10:34,680 Springs 311 00:10:39,470 --> 00:10:36,420 um as well as pseudo rajamani over in 312 00:10:40,970 --> 00:10:39,480 Isa and Pune India and Kathy Campbell in 313 00:10:43,130 --> 00:10:40,980 um New Zealand so there's all these 314 00:10:45,470 --> 00:10:43,140 amazing hot spring researchers that are 315 00:10:48,769 --> 00:10:45,480 thinking about could life form in a hot 316 00:10:50,150 --> 00:10:48,779 spring and what our Research Center kind 317 00:10:51,470 --> 00:10:50,160 of realized was that there's all these 318 00:10:53,090 --> 00:10:51,480 chemists figuring that out and doing 319 00:10:54,769 --> 00:10:53,100 stuff in the lab and there's all these 320 00:10:56,210 --> 00:10:54,779 geologists going out you know into the 321 00:10:58,190 --> 00:10:56,220 field and studying ancient and modern 322 00:10:59,990 --> 00:10:58,200 Hot Springs but it wasn't a lot of 323 00:11:02,269 --> 00:11:00,000 communication between those two groups 324 00:11:04,449 --> 00:11:02,279 so I'm really lucky I've got you know my 325 00:11:07,790 --> 00:11:04,459 rock expert my 326 00:11:09,410 --> 00:11:07,800 and then I've got Albert farrenback who 327 00:11:11,090 --> 00:11:09,420 um went through the you know NASA 328 00:11:12,829 --> 00:11:11,100 postdoc program in the states and then 329 00:11:15,290 --> 00:11:12,839 came out here to Australia to set up a 330 00:11:17,269 --> 00:11:15,300 lab in pre-building chemistry and 331 00:11:19,250 --> 00:11:17,279 together we're kind of figuring out what 332 00:11:21,470 --> 00:11:19,260 works in the lab why wouldn't that work 333 00:11:22,370 --> 00:11:21,480 in the field or what rocks what minerals 334 00:11:24,710 --> 00:11:22,380 what 335 00:11:26,630 --> 00:11:24,720 um you know real life scenarios could we 336 00:11:28,730 --> 00:11:26,640 bring into the lab the kind of ground 337 00:11:30,590 --> 00:11:28,740 truth to try and make these you know 338 00:11:32,990 --> 00:11:30,600 very lofty ideas that chemists make 339 00:11:35,090 --> 00:11:33,000 about lipids and RNA and things coming 340 00:11:36,769 --> 00:11:35,100 together if the water was super muddy 341 00:11:38,329 --> 00:11:36,779 and if there was you know gases and 342 00:11:40,370 --> 00:11:38,339 splashing and all the kind of fun stuff 343 00:11:43,370 --> 00:11:40,380 you get in a hot spring could that still 344 00:11:45,350 --> 00:11:43,380 work like how resistant are our chemical 345 00:11:48,470 --> 00:11:45,360 systems so yeah that's the work I'm 346 00:11:49,790 --> 00:11:48,480 working on at the moment oh it's so cool 347 00:11:51,350 --> 00:11:49,800 um you know and so you mentioned a few 348 00:11:53,030 --> 00:11:51,360 excellent other scientists there one of 349 00:11:54,530 --> 00:11:53,040 them has been on our show uh Bruce 350 00:11:55,850 --> 00:11:54,540 steamer joined us in a previous episode 351 00:11:58,670 --> 00:11:55,860 a few years ago for asking 352 00:12:00,350 --> 00:11:58,680 astrobiologist and you know as folks 353 00:12:02,690 --> 00:12:00,360 might know from from their work and from 354 00:12:05,750 --> 00:12:02,700 their work with the biota Institute they 355 00:12:07,790 --> 00:12:05,760 they have a hypothesis that an origin of 356 00:12:10,190 --> 00:12:07,800 life on Earth would have been more 357 00:12:13,250 --> 00:12:10,200 likely to happen around a terrestrial 358 00:12:14,509 --> 00:12:13,260 hot spring environment as opposed to as 359 00:12:17,470 --> 00:12:14,519 some people have favorite on the ocean 360 00:12:19,970 --> 00:12:17,480 floor around an ocean a submarine 361 00:12:21,889 --> 00:12:19,980 hydrothermal van and so we asked our our 362 00:12:26,210 --> 00:12:21,899 audience on the NASA astrobio Twitter 363 00:12:29,449 --> 00:12:26,220 account what they thought today and uh 364 00:12:30,590 --> 00:12:29,459 76 of the respondents thought that life 365 00:12:33,230 --> 00:12:30,600 on Earth would be more likely to 366 00:12:35,509 --> 00:12:33,240 originate and an ocean hydrothermal vein 367 00:12:37,490 --> 00:12:35,519 I'm curious Luke what do you think would 368 00:12:39,290 --> 00:12:37,500 you think life could originate or what 369 00:12:40,910 --> 00:12:39,300 is more likely to originate around a 370 00:12:42,650 --> 00:12:40,920 terrestrial hot spring environment or 371 00:12:44,389 --> 00:12:42,660 more likely around a submarine 372 00:12:47,629 --> 00:12:44,399 hydrothermal vent 373 00:12:49,129 --> 00:12:47,639 um yeah um so firstly I think that um no 374 00:12:51,290 --> 00:12:49,139 one really knows yet you know we're 375 00:12:52,970 --> 00:12:51,300 doing great research in this space 376 00:12:55,670 --> 00:12:52,980 um both within you know research around 377 00:12:57,470 --> 00:12:55,680 these fans but also in these fields 378 00:12:59,030 --> 00:12:57,480 um I personally love these hot spring 379 00:13:00,590 --> 00:12:59,040 fields and maybe I'm biased because I 380 00:13:02,449 --> 00:13:00,600 get to go there more and they're a lot 381 00:13:05,509 --> 00:13:02,459 easier to walk around in and collect 382 00:13:07,310 --> 00:13:05,519 samples from but to me um the two things 383 00:13:09,350 --> 00:13:07,320 I love about these Hot Springs is one 384 00:13:11,150 --> 00:13:09,360 their ability to 385 00:13:12,889 --> 00:13:11,160 um and this is drawing on like Bruce and 386 00:13:14,990 --> 00:13:12,899 Dave's work and other people's research 387 00:13:17,449 --> 00:13:15,000 in this space it's the ability to 388 00:13:19,670 --> 00:13:17,459 promote evaporation so if you want to 389 00:13:21,530 --> 00:13:19,680 make polymers so long chains of DNA or 390 00:13:23,690 --> 00:13:21,540 proteins and that kind of stuff it's 391 00:13:26,629 --> 00:13:23,700 quite hard to do without you know 392 00:13:28,730 --> 00:13:26,639 enzymes and complex cellular Machinery 393 00:13:30,290 --> 00:13:28,740 um in a totally wet solution but if you 394 00:13:31,670 --> 00:13:30,300 can just remove that water it's really 395 00:13:33,769 --> 00:13:31,680 easy to get these individual building 396 00:13:35,690 --> 00:13:33,779 blocks of RNA to link up into long 397 00:13:36,949 --> 00:13:35,700 chains so I think that's one reason why 398 00:13:38,449 --> 00:13:36,959 people love 399 00:13:40,730 --> 00:13:38,459 um An Origin of Life happening on the 400 00:13:42,410 --> 00:13:40,740 Earth's surface but also it's to do with 401 00:13:44,509 --> 00:13:42,420 complexity so if you go to a hot spring 402 00:13:45,829 --> 00:13:44,519 site there are literally tens of 403 00:13:48,170 --> 00:13:45,839 thousands of hot springs and they've all 404 00:13:50,329 --> 00:13:48,180 got different temperatures different PHS 405 00:13:52,430 --> 00:13:50,339 different you know um Elements and 406 00:13:54,230 --> 00:13:52,440 Minerals dissolved in them and when you 407 00:13:55,850 --> 00:13:54,240 think about how complex life is and how 408 00:13:57,410 --> 00:13:55,860 many different reactions are needed for 409 00:13:59,870 --> 00:13:57,420 life to form 410 00:14:01,910 --> 00:13:59,880 um I think that having a place of 10 000 411 00:14:03,590 --> 00:14:01,920 different chemical environments would be 412 00:14:05,329 --> 00:14:03,600 a lot easier to get that you know one 413 00:14:07,370 --> 00:14:05,339 little chance of it just linking up the 414 00:14:09,410 --> 00:14:07,380 right way we're an event which is you 415 00:14:12,350 --> 00:14:09,420 know beautifully chemically Rich systems 416 00:14:14,150 --> 00:14:12,360 the more um even though if in within a 417 00:14:16,250 --> 00:14:14,160 field it's a single point source it's 418 00:14:18,110 --> 00:14:16,260 like one vent going out into a dilute 419 00:14:21,290 --> 00:14:18,120 ocean and it's you only get one real 420 00:14:22,550 --> 00:14:21,300 main chemical gradient in that space so 421 00:14:25,009 --> 00:14:22,560 that's um some of the arguments people 422 00:14:27,170 --> 00:14:25,019 make but also events are really cool so 423 00:14:29,150 --> 00:14:27,180 yeah the jury's still out as far as I'm 424 00:14:31,190 --> 00:14:29,160 concerned that's very cool it kind of 425 00:14:34,250 --> 00:14:31,200 reminds me of an ecology course like 426 00:14:35,449 --> 00:14:34,260 learning of biogeography in and how you 427 00:14:37,310 --> 00:14:35,459 have all these different experiments 428 00:14:39,650 --> 00:14:37,320 occurring around an island chain and how 429 00:14:40,850 --> 00:14:39,660 you know in Ireland or an archipelago of 430 00:14:42,710 --> 00:14:40,860 Hot Springs you might have a lot of 431 00:14:44,870 --> 00:14:42,720 different experiments occurring as well 432 00:14:46,310 --> 00:14:44,880 that's really cool to think about 433 00:14:47,629 --> 00:14:46,320 um now I do want to talk a little bit 434 00:14:48,710 --> 00:14:47,639 before I open another Twitter to our 435 00:14:50,750 --> 00:14:48,720 audience and by the way for those 436 00:14:52,370 --> 00:14:50,760 watching on YouTube right now uh you can 437 00:14:54,889 --> 00:14:52,380 ask questions in the chat as we'll start 438 00:14:56,389 --> 00:14:54,899 coming over to me to ask Luke as well 439 00:14:57,410 --> 00:14:56,399 um and also for those watching later on 440 00:14:58,610 --> 00:14:57,420 you can always reach out to Luke later 441 00:14:59,750 --> 00:14:58,620 on as well 442 00:15:02,449 --> 00:14:59,760 um I do want to talk a bit about your 443 00:15:03,650 --> 00:15:02,459 work now in science communication too 444 00:15:05,269 --> 00:15:03,660 um not only have you been working in 445 00:15:06,949 --> 00:15:05,279 this realm of Hot Springs both with 446 00:15:08,269 --> 00:15:06,959 ancient and modern 447 00:15:09,829 --> 00:15:08,279 um you've also been doing a lot of work 448 00:15:11,210 --> 00:15:09,839 in communicating science and as I 449 00:15:13,250 --> 00:15:11,220 mentioned you know like seeing these 450 00:15:14,269 --> 00:15:13,260 people in a bar or wherever where you 451 00:15:15,769 --> 00:15:14,279 know they're just interested in what 452 00:15:18,410 --> 00:15:15,779 we're learning about astrobiology and 453 00:15:20,870 --> 00:15:18,420 what we can share I'd love to hear from 454 00:15:22,850 --> 00:15:20,880 your perspective why you think we 455 00:15:24,470 --> 00:15:22,860 scientists should 456 00:15:26,090 --> 00:15:24,480 um maybe communicate our science or why 457 00:15:27,710 --> 00:15:26,100 we should be involved in the process of 458 00:15:29,569 --> 00:15:27,720 communicating our science 459 00:15:31,250 --> 00:15:29,579 yeah no definitely 460 00:15:32,930 --> 00:15:31,260 um so I think on one hand and I don't 461 00:15:34,550 --> 00:15:32,940 know how it worked in the states I 462 00:15:36,590 --> 00:15:34,560 imagine it's similar but in Australia 463 00:15:39,050 --> 00:15:36,600 all the funding we do is really 464 00:15:41,269 --> 00:15:39,060 government funded by taxpayers dollars 465 00:15:43,850 --> 00:15:41,279 you know and I think that people always 466 00:15:45,949 --> 00:15:43,860 critique astrobiology about what's the 467 00:15:47,750 --> 00:15:45,959 real world applications you know you're 468 00:15:49,910 --> 00:15:47,760 not curing cancer you're not building a 469 00:15:52,129 --> 00:15:49,920 faster car like what's what's the value 470 00:15:54,290 --> 00:15:52,139 of this society which you know is a 471 00:15:57,530 --> 00:15:54,300 valid point you know resources are you 472 00:15:59,210 --> 00:15:57,540 know finite but I see so much Beauty in 473 00:16:01,250 --> 00:15:59,220 astrobiology I see so much of that 474 00:16:03,470 --> 00:16:01,260 ability to connect humans together but 475 00:16:05,389 --> 00:16:03,480 also to understand complex you know 476 00:16:07,009 --> 00:16:05,399 biology and medicine to develop new 477 00:16:09,829 --> 00:16:07,019 technology to go to other planets is 478 00:16:11,750 --> 00:16:09,839 such an amazing value of astrobiology 479 00:16:13,790 --> 00:16:11,760 it's just the way we communicate that 480 00:16:17,750 --> 00:16:13,800 but then again at the same time I think 481 00:16:20,150 --> 00:16:17,760 that we have a um a duty to you know in 482 00:16:22,069 --> 00:16:20,160 tax payer funded research to give that 483 00:16:24,470 --> 00:16:22,079 research back to the people you know and 484 00:16:26,689 --> 00:16:24,480 there may not be a new vaccine or a new 485 00:16:28,189 --> 00:16:26,699 car but it might be a really exciting 486 00:16:29,990 --> 00:16:28,199 talk that they can listen to to and 487 00:16:31,850 --> 00:16:30,000 learn about how we're you know looking 488 00:16:33,470 --> 00:16:31,860 deep into these events or looking at you 489 00:16:35,689 --> 00:16:33,480 know Europa or Mars or that kind of 490 00:16:37,430 --> 00:16:35,699 thing so I see it as a bit of a Duty as 491 00:16:39,050 --> 00:16:37,440 a community of astrobiologists to get 492 00:16:41,329 --> 00:16:39,060 involved in that space 493 00:16:43,129 --> 00:16:41,339 very cool and then you you found it or 494 00:16:44,930 --> 00:16:43,139 co-founded practical 495 00:16:46,730 --> 00:16:44,940 um a platform for sharing your science 496 00:16:48,470 --> 00:16:46,740 and for developing science communication 497 00:16:50,509 --> 00:16:48,480 science education would you mind 498 00:16:53,269 --> 00:16:50,519 explaining that for our audience yeah no 499 00:16:55,790 --> 00:16:53,279 definitely so I created practical with 500 00:16:58,069 --> 00:16:55,800 um an amazing PhD student in the lab I 501 00:17:00,530 --> 00:16:58,079 was in Bonnie tease who's now graduated 502 00:17:02,389 --> 00:17:00,540 and just got a postdoc at JPL which is 503 00:17:04,370 --> 00:17:02,399 very exciting so for anyone on the stage 504 00:17:05,390 --> 00:17:04,380 she'll be over there shortly 505 00:17:07,329 --> 00:17:05,400 um and Bonnie and I were really 506 00:17:09,890 --> 00:17:07,339 interested in how do you engage 507 00:17:11,929 --> 00:17:09,900 audiences outside a general you know 508 00:17:14,510 --> 00:17:11,939 choir that we preach to in science 509 00:17:16,610 --> 00:17:14,520 communicators so you do a talk in a pub 510 00:17:18,350 --> 00:17:16,620 or you know you do something and that's 511 00:17:20,210 --> 00:17:18,360 you know trying to get out into your 512 00:17:21,949 --> 00:17:20,220 community but it's still just a whole 513 00:17:24,949 --> 00:17:21,959 bunch of PhD students turning up to the 514 00:17:27,049 --> 00:17:24,959 pub you know how do you get people 515 00:17:29,450 --> 00:17:27,059 um you know artists people at music 516 00:17:31,730 --> 00:17:29,460 festivals people you know outside of our 517 00:17:33,590 --> 00:17:31,740 little bubble of science excited about 518 00:17:35,990 --> 00:17:33,600 science and learning and engaging in 519 00:17:38,029 --> 00:17:36,000 that dialogue so we create a practical 520 00:17:40,850 --> 00:17:38,039 we started off building a whole bunch of 521 00:17:43,490 --> 00:17:40,860 online workshops from that you know um 522 00:17:45,169 --> 00:17:43,500 it's been a container for us to work 523 00:17:46,490 --> 00:17:45,179 with dancers you know contemporary 524 00:17:48,169 --> 00:17:46,500 dancers thinking about how could the 525 00:17:50,029 --> 00:17:48,179 origin of Life be expressed through 526 00:17:51,950 --> 00:17:50,039 movement you know we work with neural 527 00:17:53,390 --> 00:17:51,960 artists we work with Comedians and 528 00:17:55,909 --> 00:17:53,400 performers and it's all these amazing 529 00:17:57,950 --> 00:17:55,919 ways to bring people outside of science 530 00:18:00,409 --> 00:17:57,960 into what we do and also bring 531 00:18:03,470 --> 00:18:00,419 scientists out of our little world into 532 00:18:05,270 --> 00:18:03,480 the broader community so yeah absolutely 533 00:18:07,250 --> 00:18:05,280 and I'd love to unpack two things there 534 00:18:08,870 --> 00:18:07,260 one is the comedy and we'll talk about 535 00:18:10,430 --> 00:18:08,880 that in a moment but but also you 536 00:18:12,710 --> 00:18:10,440 mentioned contemporary dance and I love 537 00:18:14,750 --> 00:18:12,720 there's like the the dancier thesis 538 00:18:16,909 --> 00:18:14,760 competition that some people have and 539 00:18:18,950 --> 00:18:16,919 there's other ways to explore like our 540 00:18:20,690 --> 00:18:18,960 science and dance and one of my old lab 541 00:18:24,049 --> 00:18:20,700 mates for instance uh Betsy Swanner 542 00:18:26,570 --> 00:18:24,059 who's now a professor in geology uh she 543 00:18:29,630 --> 00:18:26,580 had done a dance of her thesis exploring 544 00:18:31,430 --> 00:18:29,640 uh subsurface microbes mediating iron 545 00:18:32,510 --> 00:18:31,440 metabolism 546 00:18:34,490 --> 00:18:32,520 um I wonder if you can explain for us 547 00:18:37,010 --> 00:18:34,500 like how do you see dance how do you see 548 00:18:40,370 --> 00:18:37,020 contemporary dance actually effectively 549 00:18:42,289 --> 00:18:40,380 sharing science yeah definitely so um 550 00:18:45,110 --> 00:18:42,299 the one example that I think is the best 551 00:18:47,330 --> 00:18:45,120 is that we um partner with Eliza Cooper 552 00:18:50,270 --> 00:18:47,340 who's an amazing um contemporary dancer 553 00:18:53,029 --> 00:18:50,280 here in Sydney and she had already been 554 00:18:55,490 --> 00:18:53,039 she's also studying um microbiology and 555 00:18:57,230 --> 00:18:55,500 science was thinking about life and its 556 00:18:58,970 --> 00:18:57,240 formation and put together this show and 557 00:19:02,810 --> 00:18:58,980 we thought we need scientists to see 558 00:19:04,970 --> 00:19:02,820 that and what um so we know I we got her 559 00:19:06,529 --> 00:19:04,980 to come to unsw we facilitated a big 560 00:19:08,029 --> 00:19:06,539 panel discussion and kind of got his 561 00:19:10,850 --> 00:19:08,039 Round Table talk of everyone together 562 00:19:12,350 --> 00:19:10,860 and what I loved about it was that most 563 00:19:16,010 --> 00:19:12,360 of the dance was 564 00:19:17,510 --> 00:19:16,020 um very slow and it was like little 565 00:19:19,070 --> 00:19:17,520 um actually it's really cute it had like 566 00:19:21,350 --> 00:19:19,080 you know Dances crawling around with 567 00:19:23,090 --> 00:19:21,360 like lettuce leaves as little ears and 568 00:19:25,370 --> 00:19:23,100 were kind of like moving across the 569 00:19:27,409 --> 00:19:25,380 stage and at the end she was saying that 570 00:19:29,270 --> 00:19:27,419 when we think about the evolution and 571 00:19:30,590 --> 00:19:29,280 history of life you often get a 572 00:19:32,870 --> 00:19:30,600 highlights reel you know it's like 573 00:19:34,130 --> 00:19:32,880 origin of life and then eukaryotes and 574 00:19:35,450 --> 00:19:34,140 then they all started having sex and 575 00:19:36,710 --> 00:19:35,460 then they had eyes and like it's just 576 00:19:38,990 --> 00:19:36,720 you can really 577 00:19:41,390 --> 00:19:39,000 um go through it so quickly but so much 578 00:19:44,210 --> 00:19:41,400 of hour of shared history as you know 579 00:19:46,310 --> 00:19:44,220 living entities on this planet revolved 580 00:19:48,830 --> 00:19:46,320 around like billions of years of just 581 00:19:50,990 --> 00:19:48,840 stromatolite slowly bubbling away oxygen 582 00:19:53,630 --> 00:19:51,000 in an ocean or little slugs just moving 583 00:19:54,830 --> 00:19:53,640 around eating dirt and um I think it's 584 00:19:56,870 --> 00:19:54,840 really 585 00:19:58,370 --> 00:19:56,880 humbling to think about the long history 586 00:20:00,590 --> 00:19:58,380 we have and the very boring history 587 00:20:02,029 --> 00:20:00,600 really of life and I think that helped 588 00:20:04,370 --> 00:20:02,039 me as a scientists understand that 589 00:20:06,169 --> 00:20:04,380 better for sitting for an hour of a very 590 00:20:08,570 --> 00:20:06,179 um exciting but slow dance that 591 00:20:10,370 --> 00:20:08,580 sometimes yeah yeah I mean there's 592 00:20:11,810 --> 00:20:10,380 there's so many interesting ways for us 593 00:20:13,610 --> 00:20:11,820 to like untangle those little bits of 594 00:20:15,350 --> 00:20:13,620 knowledge that we have and we've 595 00:20:17,570 --> 00:20:15,360 uncovered through Millennia now of 596 00:20:18,950 --> 00:20:17,580 developing science as a tool and for for 597 00:20:20,750 --> 00:20:18,960 us to have learned so much it's what's 598 00:20:22,190 --> 00:20:20,760 interesting I it's actually kind of put 599 00:20:23,690 --> 00:20:22,200 it into that framework too where you 600 00:20:24,890 --> 00:20:23,700 slow things down 601 00:20:26,570 --> 00:20:24,900 um because you're right I think a lot of 602 00:20:28,610 --> 00:20:26,580 us just we have these certain images of 603 00:20:30,529 --> 00:20:28,620 certain scientific ideas and even our 604 00:20:32,690 --> 00:20:30,539 scientists have certain images or some 605 00:20:34,370 --> 00:20:32,700 other scientific ideas outside of our 606 00:20:35,810 --> 00:20:34,380 own fields and when we start learning 607 00:20:38,330 --> 00:20:35,820 more about it we really find that we 608 00:20:39,710 --> 00:20:38,340 need analogies and we need other ways to 609 00:20:42,049 --> 00:20:39,720 speak to what it means to be human to 610 00:20:43,610 --> 00:20:42,059 really understand those topics and so 611 00:20:45,350 --> 00:20:43,620 um that's very cool 612 00:20:47,750 --> 00:20:45,360 um now of course I do want to talk about 613 00:20:49,430 --> 00:20:47,760 stand-up science comedy with you I 614 00:20:51,710 --> 00:20:49,440 myself have been fortunate to be on a 615 00:20:53,630 --> 00:20:51,720 stage doing comedy um both at a museum 616 00:20:55,730 --> 00:20:53,640 as well as at a bar 617 00:20:58,310 --> 00:20:55,740 um you know it's a very entry experience 618 00:21:00,169 --> 00:20:58,320 I'd love to hear like what what really 619 00:21:01,850 --> 00:21:00,179 turned you all into doing stand-up 620 00:21:02,990 --> 00:21:01,860 science comedy and kind of got you into 621 00:21:05,390 --> 00:21:03,000 that Realm 622 00:21:06,289 --> 00:21:05,400 yeah um so I just want to say I'm not a 623 00:21:08,750 --> 00:21:06,299 comedian 624 00:21:11,029 --> 00:21:08,760 um I don't really find myself 625 00:21:12,590 --> 00:21:11,039 um I wasn't particularly funny or you 626 00:21:14,150 --> 00:21:12,600 know in that space I just had a lot of 627 00:21:16,070 --> 00:21:14,160 friends who work in meetings and ran 628 00:21:18,529 --> 00:21:16,080 comedy rooms so I would see a lot of 629 00:21:20,690 --> 00:21:18,539 comedy and I think sitting there I saw 630 00:21:22,490 --> 00:21:20,700 that 631 00:21:24,830 --> 00:21:22,500 stage and just say 632 00:21:26,810 --> 00:21:24,840 hey and everyone's captivated you know 633 00:21:28,850 --> 00:21:26,820 or like ask a simple question or open up 634 00:21:30,470 --> 00:21:28,860 a single you know statement and the 635 00:21:32,750 --> 00:21:30,480 whole crowds on the edge of their seat 636 00:21:35,029 --> 00:21:32,760 and I was like why can't professors at 637 00:21:37,010 --> 00:21:35,039 Uni do that why can't we have 638 00:21:38,630 --> 00:21:37,020 um you know scientists who get really 639 00:21:41,029 --> 00:21:38,640 excited about these things being able to 640 00:21:43,909 --> 00:21:41,039 get there and get people interested and 641 00:21:45,890 --> 00:21:43,919 engaged so quickly and um yeah I wanted 642 00:21:47,750 --> 00:21:45,900 to get comedians to teach scientists to 643 00:21:49,970 --> 00:21:47,760 be more engaging and also get people 644 00:21:53,029 --> 00:21:49,980 talking science on a bigger comedy stage 645 00:21:54,110 --> 00:21:53,039 so that's where it all came from yeah so 646 00:21:55,850 --> 00:21:54,120 it's interesting that you said you 647 00:21:57,830 --> 00:21:55,860 weren't particularly funny or you don't 648 00:21:59,690 --> 00:21:57,840 think of yourself as being a comedian uh 649 00:22:02,450 --> 00:21:59,700 so you you did share with us a little 650 00:22:03,890 --> 00:22:02,460 clip uh of some of your comedy and so I 651 00:22:05,450 --> 00:22:03,900 think we're actually going to share just 652 00:22:08,330 --> 00:22:05,460 a little piece of your comedy with our 653 00:22:10,549 --> 00:22:08,340 audience right now uh and so I I think 654 00:22:11,570 --> 00:22:10,559 uh we'll roll it here into the moment 655 00:22:13,250 --> 00:22:11,580 um of course you know I won't be seeing 656 00:22:14,810 --> 00:22:13,260 it but our audience will and for the 657 00:22:16,310 --> 00:22:14,820 audiences you're watching this thing to 658 00:22:17,810 --> 00:22:16,320 yourself was that funny or not let us 659 00:22:19,930 --> 00:22:17,820 know in the chat 660 00:22:22,430 --> 00:22:19,940 um so like the other day 661 00:22:24,710 --> 00:22:22,440 instructor and they asked me what I do 662 00:22:27,549 --> 00:22:24,720 and I told them I studied astrobiology 663 00:22:31,750 --> 00:22:27,559 and all of a sudden they go oh my God 664 00:22:34,250 --> 00:22:31,760 I'm a Gemini foreign 665 00:22:38,409 --> 00:22:34,260 you get to do your whole PhD in 666 00:22:40,970 --> 00:22:38,419 astrology that is so Aquarius of you 667 00:22:42,830 --> 00:22:40,980 you've got to help me out my boyfriend 668 00:22:44,529 --> 00:22:42,840 and I have been a mess ever since the 669 00:22:46,850 --> 00:22:44,539 Venus retrograde 670 00:22:48,950 --> 00:22:46,860 and as I said you know this could be a 671 00:22:50,570 --> 00:22:48,960 great learning opportunity and after 672 00:22:52,789 --> 00:22:50,580 another bit of a chat and I've found out 673 00:22:54,770 --> 00:22:52,799 what astrology means today 674 00:22:56,570 --> 00:22:54,780 say Hey I'm really sorry 675 00:22:58,530 --> 00:22:56,580 I can't help you understand why the 676 00:23:02,630 --> 00:22:58,540 rotation of space 677 00:23:07,510 --> 00:23:04,789 and even though the surface of Venus is 678 00:23:08,750 --> 00:23:07,520 actually 400 degrees Celsius 679 00:23:10,669 --> 00:23:08,760 [Music] 680 00:23:13,250 --> 00:23:10,679 all right folks coming back to our show 681 00:23:15,230 --> 00:23:13,260 now I think it was pretty funny 682 00:23:17,450 --> 00:23:15,240 um so so Luke I have to say I found your 683 00:23:18,529 --> 00:23:17,460 your stand-up set very good 684 00:23:19,730 --> 00:23:18,539 um now of course there's some other 685 00:23:22,010 --> 00:23:19,740 parts of your standards that we haven't 686 00:23:23,390 --> 00:23:22,020 shared and so um I'd love it for any of 687 00:23:25,610 --> 00:23:23,400 our audience members especially those in 688 00:23:27,230 --> 00:23:25,620 Australia right now uh to go check out 689 00:23:28,850 --> 00:23:27,240 your stand-up science comedy when they 690 00:23:30,230 --> 00:23:28,860 have a chance to 691 00:23:32,870 --> 00:23:30,240 um and so you know it's fun just that 692 00:23:34,850 --> 00:23:32,880 chance to really to share science in in 693 00:23:36,409 --> 00:23:34,860 a humorous manner 694 00:23:38,390 --> 00:23:36,419 um to find ways to make some punch lines 695 00:23:40,070 --> 00:23:38,400 too and one thing I personally found was 696 00:23:43,010 --> 00:23:40,080 that it forced me to really think about 697 00:23:45,649 --> 00:23:43,020 not just analogies not just stories 698 00:23:48,230 --> 00:23:45,659 about my science but also stories that 699 00:23:51,049 --> 00:23:48,240 were you know really seeking to elicit a 700 00:23:52,669 --> 00:23:51,059 very specific human emotional reaction 701 00:23:54,529 --> 00:23:52,679 um how do you feel about that like what 702 00:23:57,710 --> 00:23:54,539 was the the process for you in sculpting 703 00:23:59,510 --> 00:23:57,720 your comedy yeah um I think for me it 704 00:24:01,250 --> 00:23:59,520 was really around 705 00:24:03,409 --> 00:24:01,260 breaking down these barriers of what 706 00:24:04,850 --> 00:24:03,419 makes a scientist you know and um you 707 00:24:06,350 --> 00:24:04,860 know you saw my little 708 00:24:08,690 --> 00:24:06,360 um you know bit there it was all around 709 00:24:10,370 --> 00:24:08,700 the way that people perceive me as a 710 00:24:12,890 --> 00:24:10,380 scientist in different walks of my life 711 00:24:15,289 --> 00:24:12,900 but you know we had um six other amazing 712 00:24:17,330 --> 00:24:15,299 scientists join me and like they were 713 00:24:18,230 --> 00:24:17,340 talking about Tinder dates they would go 714 00:24:19,490 --> 00:24:18,240 on and then people would figure 715 00:24:20,870 --> 00:24:19,500 scientists and ask them all these 716 00:24:22,610 --> 00:24:20,880 questions on a way that their parents 717 00:24:24,289 --> 00:24:22,620 would interact with them or the way that 718 00:24:27,049 --> 00:24:24,299 supervisors would view them as 719 00:24:28,909 --> 00:24:27,059 undergrads and I think that if we had 720 00:24:30,289 --> 00:24:28,919 this very narrow idea of what a 721 00:24:32,330 --> 00:24:30,299 scientist is 722 00:24:34,310 --> 00:24:32,340 um it excludes people who don't fit into 723 00:24:35,630 --> 00:24:34,320 that category from joining science but 724 00:24:37,610 --> 00:24:35,640 it also makes people distrust you 725 00:24:40,250 --> 00:24:37,620 because like oh if you're like a boring 726 00:24:42,049 --> 00:24:40,260 nerd who you know doesn't you know live 727 00:24:43,370 --> 00:24:42,059 a normal life how can I trust you to 728 00:24:45,409 --> 00:24:43,380 make decisions about you know the 729 00:24:46,970 --> 00:24:45,419 science that impacts my life so I think 730 00:24:48,649 --> 00:24:46,980 it's a really important way to 731 00:24:50,330 --> 00:24:48,659 communicate science and to break down 732 00:24:54,350 --> 00:24:50,340 those barriers on um a lot of different 733 00:24:56,870 --> 00:24:54,360 levels which is really fun absolutely uh 734 00:24:58,370 --> 00:24:56,880 so many of our audience members or their 735 00:25:00,110 --> 00:24:58,380 young students and in you know High 736 00:25:02,090 --> 00:25:00,120 School Secondary School their their 737 00:25:04,310 --> 00:25:02,100 students in in their early Collegiate or 738 00:25:06,409 --> 00:25:04,320 even graduate school levels um and some 739 00:25:08,390 --> 00:25:06,419 are continuing education some are are 740 00:25:09,890 --> 00:25:08,400 people who've had a life and a career 741 00:25:11,990 --> 00:25:09,900 but now they're interested in exploring 742 00:25:13,190 --> 00:25:12,000 more about astrobiology and one thing 743 00:25:15,470 --> 00:25:13,200 you hear a lot that people feel like 744 00:25:17,630 --> 00:25:15,480 they can't be astrobiologists unless 745 00:25:20,270 --> 00:25:17,640 they have a PhD in astronomy or geology 746 00:25:21,770 --> 00:25:20,280 or biology and it's like Mary wojtek 747 00:25:24,529 --> 00:25:21,780 always says that you know everyone can 748 00:25:26,450 --> 00:25:24,539 be an astrobiologist it's just being you 749 00:25:28,130 --> 00:25:26,460 know interested in this and in this this 750 00:25:29,450 --> 00:25:28,140 Quest that we have to understand what 751 00:25:30,649 --> 00:25:29,460 life is 752 00:25:33,409 --> 00:25:30,659 um one thing that you had mentioned to 753 00:25:35,330 --> 00:25:33,419 me um before our show started was that 754 00:25:37,850 --> 00:25:35,340 you'd like acknowledging experts outside 755 00:25:39,590 --> 00:25:37,860 of our field and I I wonder if you can 756 00:25:41,870 --> 00:25:39,600 explain on that a little bit before our 757 00:25:44,750 --> 00:25:41,880 audience the importance of acknowledging 758 00:25:46,250 --> 00:25:44,760 expertise Beyond just astrobiology 759 00:25:48,950 --> 00:25:46,260 beyond just science 760 00:25:50,510 --> 00:25:48,960 yeah no definitely so um as I said I 761 00:25:52,130 --> 00:25:50,520 didn't think I was an originally funny 762 00:25:54,830 --> 00:25:52,140 person but I work with some great 763 00:25:56,810 --> 00:25:54,840 comedians um and great trainers who help 764 00:25:58,909 --> 00:25:56,820 me to think about you know comedy and 765 00:26:00,289 --> 00:25:58,919 joke writing in a really new light and 766 00:26:02,990 --> 00:26:00,299 they were the experts and as I said 767 00:26:04,789 --> 00:26:03,000 before you know um you go to a comedy 768 00:26:07,190 --> 00:26:04,799 show and these people on stage they've 769 00:26:08,990 --> 00:26:07,200 spent years honing this skill you know 770 00:26:11,210 --> 00:26:09,000 their their artists they're experts in 771 00:26:12,830 --> 00:26:11,220 their craft of communication and you 772 00:26:14,450 --> 00:26:12,840 know I love having a chat I love you 773 00:26:16,190 --> 00:26:14,460 know doing some kinds of science 774 00:26:17,870 --> 00:26:16,200 communication but working with them was 775 00:26:20,570 --> 00:26:17,880 the real beauty of it and it's the same 776 00:26:22,130 --> 00:26:20,580 way of bringing in artists to rethink a 777 00:26:24,049 --> 00:26:22,140 way that you see the world or bringing 778 00:26:26,029 --> 00:26:24,059 in you know philosophers are bringing in 779 00:26:28,070 --> 00:26:26,039 economists or anyone like there's so 780 00:26:29,510 --> 00:26:28,080 many intersections in the way that we 781 00:26:31,430 --> 00:26:29,520 have to 782 00:26:32,810 --> 00:26:31,440 um view astrobiology because it's such a 783 00:26:34,430 --> 00:26:32,820 huge question like you know one 784 00:26:36,649 --> 00:26:34,440 physicist isn't going to solve it you 785 00:26:38,690 --> 00:26:36,659 know we need all of humanity to come 786 00:26:41,450 --> 00:26:38,700 together so I think that's what you said 787 00:26:42,710 --> 00:26:41,460 anyone can be an astrobiologist and you 788 00:26:45,049 --> 00:26:42,720 know if you're out there and you've got 789 00:26:47,510 --> 00:26:45,059 skills or experiences in totally 790 00:26:49,370 --> 00:26:47,520 different areas um don't be shy to 791 00:26:52,310 --> 00:26:49,380 promote those skills and think about how 792 00:26:53,870 --> 00:26:52,320 can I engage in astrobiology with my own 793 00:26:54,769 --> 00:26:53,880 skill set you know I've got started in 794 00:26:56,090 --> 00:26:54,779 this because I was really good at 795 00:26:58,730 --> 00:26:56,100 setting up tents in the desert you know 796 00:27:00,710 --> 00:26:58,740 that was my intro and my little niche in 797 00:27:02,390 --> 00:27:00,720 astrobiology and now you know we're 798 00:27:04,190 --> 00:27:02,400 running camps where NASA visits to 799 00:27:07,190 --> 00:27:04,200 pilborough and for school kids out there 800 00:27:08,810 --> 00:27:07,200 and amazing stuff just from um you know 801 00:27:11,830 --> 00:27:08,820 just from my passion and my interests so 802 00:27:15,710 --> 00:27:11,840 yeah don't be shy just value your skills 803 00:27:17,029 --> 00:27:15,720 yeah it's so groovy I will say so I see 804 00:27:18,710 --> 00:27:17,039 you in the chat on YouTube some folks 805 00:27:20,090 --> 00:27:18,720 that said that was very funny 806 00:27:21,590 --> 00:27:20,100 um and a reminder for those watching on 807 00:27:23,750 --> 00:27:21,600 YouTube right now you can actually ask 808 00:27:25,310 --> 00:27:23,760 your questions in the chat for Luke 809

838 00:28:27,110 --> 00:28:24,600 science and astrobiology there's so much 839 00:28:30,350 --> 00:28:27,120 media out there in the world we humans 840 00:28:33,169 --> 00:28:30,360 are storytellers comic books magazines 841 00:28:35,450 --> 00:28:33,179 movies television shows there's so many 842 00:28:37,610 --> 00:28:35,460 stories that we tell and so I'm curious 843 00:28:40,250 --> 00:28:37,620 you know what stories have inspired you 844 00:28:41,750 --> 00:28:40,260 the most to want to explore more about 845 00:28:44,269 --> 00:28:41,760 life in the universe 846 00:28:45,830 --> 00:28:44,279 yeah um so I recently finished reading 847 00:28:47,029 --> 00:28:45,840 project Hail Mary 848 00:28:49,250 --> 00:28:47,039 um which is by the same over who wrote 849 00:28:51,769 --> 00:28:49,260 The Martian and um I just love the 850 00:28:53,750 --> 00:28:51,779 ability to weave like you know they're 851 00:28:56,870 --> 00:28:53,760 talking about maths equations they're 852 00:28:59,269 --> 00:28:56,880 weaving like real science into a fiction 853 00:29:01,250 --> 00:28:59,279 story um an astrology as well and a 854 00:29:02,870 --> 00:29:01,260 really captivating exciting way and I 855 00:29:05,090 --> 00:29:02,880 learned a lot of really cool science out 856 00:29:07,549 --> 00:29:05,100 of that as well so um that's a narrative 857 00:29:09,409 --> 00:29:07,559 that I really enjoyed recently yeah very 858 00:29:11,149 --> 00:29:09,419 cool yeah it's Andrew wrote The Martian 859 00:29:12,710 --> 00:29:11,159 like it was a great book I haven't read 860 00:29:13,549 --> 00:29:12,720 projectile Mary yet but I definitely 861 00:29:14,930 --> 00:29:13,559 should 862 00:29:16,490 --> 00:29:14,940 um it's on my list of things to read so 863 00:29:17,810 --> 00:29:16,500 that's very cool 864 00:29:18,769 --> 00:29:17,820 um so let's let's talk about your career 865 00:29:20,389 --> 00:29:18,779 a little bit 866 00:29:22,310 --> 00:29:20,399 um if you could go back in time to that 867 00:29:23,870 --> 00:29:22,320 that 20 year old Luke and talk to him 868 00:29:25,970 --> 00:29:23,880 and visit yourself 869 00:29:28,370 --> 00:29:25,980 um what advice would you give the young 870 00:29:30,889 --> 00:29:28,380 version of yourself 871 00:29:33,470 --> 00:29:30,899 yeah I think just follow your passion I 872 00:29:34,909 --> 00:29:33,480 think that passion sings so loudly and I 873 00:29:36,889 --> 00:29:34,919 think I can imagine for people like 874 00:29:38,990 --> 00:29:36,899 yourself and I know my supervisors 875 00:29:41,810 --> 00:29:39,000 always say this to me it's my passion 876 00:29:43,310 --> 00:29:41,820 it's my interest it's my excitement that 877 00:29:44,630 --> 00:29:43,320 um draws me into these projects and sort 878 00:29:46,730 --> 00:29:44,640 of lets me have all these amazing 879 00:29:48,590 --> 00:29:46,740 opportunities so I think that what 880 00:29:51,350 --> 00:29:48,600 you're excited by what interests you 881 00:29:52,789 --> 00:29:51,360 just like stick to that and um you know 882 00:29:54,230 --> 00:29:52,799 even if it's not the most you know 883 00:29:56,510 --> 00:29:54,240 prestigious career at least you're gonna 884 00:29:58,070 --> 00:29:56,520 be having fun but also it will end up 885 00:29:59,810 --> 00:29:58,080 being a great career because people will 886 00:30:02,510 --> 00:29:59,820 recognize that passion 887 00:30:04,130 --> 00:30:02,520 I love that yeah yeah I always I always 888 00:30:05,930 --> 00:30:04,140 I love this question because I have no 889 00:30:09,110 --> 00:30:05,940 idea what I would say to myself because 890 00:30:10,549 --> 00:30:09,120 you know I was I was I had no idea what 891 00:30:12,230 --> 00:30:10,559 I wanted to be when I grew up when I was 892 00:30:13,490 --> 00:30:12,240 20 and I'm almost 40 now and I still 893 00:30:15,110 --> 00:30:13,500 have no idea what I want to be when I 894 00:30:16,430 --> 00:30:15,120 grow up so it's kind of fun right 895 00:30:17,930 --> 00:30:16,440 there's a lot of things you can explore 896 00:30:19,549 --> 00:30:17,940 and adventure and yeah you can learn a 897 00:30:20,990 --> 00:30:19,559 lot along the way 898 00:30:22,310 --> 00:30:21,000 um so here's another one about asking 899 00:30:24,230 --> 00:30:22,320 questions 900 00:30:26,690 --> 00:30:24,240 um I personally I love thinking not just 901 00:30:28,789 --> 00:30:26,700 about where we are now and where we're 902 00:30:31,010 --> 00:30:28,799 going in the next you know one or two or 903 00:30:33,710 --> 00:30:31,020 ten years but you know in the next 904 00:30:37,070 --> 00:30:33,720 Century in the next millennium where our 905 00:30:39,409 --> 00:30:37,080 species or our biosphere might go to and 906 00:30:42,110 --> 00:30:39,419 so assuming humans are here in a hundred 907 00:30:44,389 --> 00:30:42,120 years if you could go to the Future and 908 00:30:48,710 --> 00:30:44,399 meet Human Society a century from now 909 00:30:53,269 --> 00:30:51,409 um I guess how did I do it basically you 910 00:30:55,730 --> 00:30:53,279 know like we're on such a trajectory of 911 00:30:58,250 --> 00:30:55,740 environmental destruction and a lot of 912 00:31:00,169 --> 00:30:58,260 social um upheaval at the moment and 913 00:31:01,730 --> 00:31:00,179 I'll be you know fascinated to see how 914 00:31:04,070 --> 00:31:01,740 we can weave through that and live 915 00:31:05,690 --> 00:31:04,080 sustainably and you know in harmony with 916 00:31:07,549 --> 00:31:05,700 Earth so yeah I'd really just be like 917 00:31:08,750 --> 00:31:07,559 hey how did you get over all these 918 00:31:10,970 --> 00:31:08,760 problems that we're facing at the moment 919 00:31:13,250 --> 00:31:10,980 that would really excite me yeah 920 00:31:15,529 --> 00:31:13,260 very cool 921 00:31:17,450 --> 00:31:15,539 um so right now you know not just NASA 922 00:31:19,970 --> 00:31:17,460 but many space agencies many scientists 923 00:31:24,669 --> 00:31:19,980 many Engineers around the world are 924 00:31:29,630 --> 00:31:27,830 to look for life out there in the 925 00:31:31,549 --> 00:31:29,640 universe on other worlds in our solar 926 00:31:33,529 --> 00:31:31,559 system and now we're looking at the 927 00:31:35,570 --> 00:31:33,539 atmospheres of exoplanets you know it's 928 00:31:38,570 --> 00:31:35,580 it's a kind of a mind-blowing moment in 929 00:31:40,310 --> 00:31:38,580 time but one question I I like posing 930 00:31:42,529 --> 00:31:40,320 and you know you can always say no if 931 00:31:45,409 --> 00:31:42,539 you don't have an answer for this but 932 00:31:47,090 --> 00:31:45,419 um if there is alien life out there do 933 00:31:50,090 --> 00:31:47,100 you think we're most likely to find it 934 00:31:52,010 --> 00:31:50,100 first in our solar system on another 935 00:31:54,470 --> 00:31:52,020 world or do you think we're more likely 936 00:31:56,090 --> 00:31:54,480 to find it on an exoplanet in another 937 00:31:59,029 --> 00:31:56,100 solar system 938 00:32:01,070 --> 00:31:59,039 yeah interesting I think that um 939 00:32:03,289 --> 00:32:01,080 as you saw with things like you know 940 00:32:04,789 --> 00:32:03,299 potentially detecting phosphate on Venus 941 00:32:06,649 --> 00:32:04,799 and that kind of stuff 942 00:32:08,690 --> 00:32:06,659 um what a biomarker is or what evidence 943 00:32:11,090 --> 00:32:08,700 for life is can be very varied you know 944 00:32:14,409 --> 00:32:11,100 and people disagree on that 945 00:32:17,090 --> 00:32:14,419 um I personally think that perhaps a 946 00:32:19,909 --> 00:32:17,100 sure answer might come from within our 947 00:32:22,430 --> 00:32:19,919 solar system where if we find a direct 948 00:32:24,110 --> 00:32:22,440 you know little bit of bacteria irking 949 00:32:25,310 --> 00:32:24,120 out its life on Mars under a rock or 950 00:32:27,350 --> 00:32:25,320 somewhere like that'd be pretty hard to 951 00:32:29,029 --> 00:32:27,360 argue with but you know if we detect 952 00:32:30,830 --> 00:32:29,039 some really distant technical signature 953 00:32:32,510 --> 00:32:30,840 or a bit of you know Alien made 954 00:32:35,090 --> 00:32:32,520 pollution in an atmosphere and some 955 00:32:36,409 --> 00:32:35,100 exoplanet I just imagine that arguments 956 00:32:38,210 --> 00:32:36,419 popping up about that and people just 957 00:32:39,830 --> 00:32:38,220 getting so into it I think it may take 958 00:32:41,630 --> 00:32:39,840 years before we actually agree on it 959 00:32:43,310 --> 00:32:41,640 which will kind of ruin the fun I want 960 00:32:45,710 --> 00:32:43,320 to have that headline being like aliens 961 00:32:47,750 --> 00:32:45,720 found you know coming out so yeah that's 962 00:32:49,490 --> 00:32:47,760 why I think it'll be easier to prove it 963 00:32:52,370 --> 00:32:49,500 here on Earth or here in our solar 964 00:32:54,289 --> 00:32:52,380 system a lot quicker very cool unless 965 00:32:56,389 --> 00:32:54,299 it's a techno signature if it's a ticket 966 00:32:58,490 --> 00:32:56,399 in our solar system or anywhere else 967 00:33:01,130 --> 00:32:58,500 then that's much easier that's much 968 00:33:01,730 --> 00:33:01,140 easier you know definitive sign right 969 00:33:04,090 --> 00:33:01,740 um 970 00:33:06,889 --> 00:33:04,100 so let's talk about the future again 971 00:33:08,870 --> 00:33:06,899 what is what is something or some group 972 00:33:11,090 --> 00:33:08,880 of things that that really excite you 973 00:33:12,649 --> 00:33:11,100 right now about the future 974 00:33:14,570 --> 00:33:12,659 yeah I'm 975 00:33:16,490 --> 00:33:14,580 I'm honestly really excited the way that 976 00:33:18,350 --> 00:33:16,500 astrology Community is growing and 977 00:33:20,750 --> 00:33:18,360 accepting more people into it you know I 978 00:33:22,850 --> 00:33:20,760 think that as I'm sure young many young 979 00:33:24,590 --> 00:33:22,860 scientists that are listening in um I 980 00:33:26,509 --> 00:33:24,600 know for myself I was like 981 00:33:27,950 --> 00:33:26,519 all science has been done you know 982 00:33:29,210 --> 00:33:27,960 they've discovered all the planets in 983 00:33:31,070 --> 00:33:29,220 the solar system they know all the 984 00:33:32,930 --> 00:33:31,080 elements who know physics is you know 985 00:33:35,029 --> 00:33:32,940 Dan and Einstein's done and all and I 986 00:33:36,830 --> 00:33:35,039 was like where where's the where's the 987 00:33:38,570 --> 00:33:36,840 new stuff that you know us as young 988 00:33:40,549 --> 00:33:38,580 scientists in this generation can 989 00:33:43,009 --> 00:33:40,559 explore and I really see it in 990 00:33:44,990 --> 00:33:43,019 astrobiology there's like no 991 00:33:47,149 --> 00:33:45,000 um we have no idea what's going on like 992 00:33:48,529 --> 00:33:47,159 it's really around origin of life in 993 00:33:50,509 --> 00:33:48,539 particular but all this kind of stuff 994 00:33:52,909 --> 00:33:50,519 they're finding tens of planets a day 995 00:33:56,630 --> 00:33:52,919 and they're just like you know exploding 996 00:33:58,190 --> 00:33:56,640 and I think astrology could be query 997 00:34:00,289 --> 00:33:58,200 um you know gatekeeping keeping people 998 00:34:01,549 --> 00:34:00,299 out but I see generally very open and 999 00:34:03,230 --> 00:34:01,559 they have these big conferences where 1000 00:34:06,950 --> 00:34:03,240 everyone's invited and that really 1001 00:34:09,889 --> 00:34:06,960 excites me so um yeah yeah I agree yeah 1002 00:34:12,190 --> 00:34:09,899 I will say like absaican it was so great 1003 00:34:13,790 --> 00:34:12,200 to see amongst the younger 1004 00:34:15,470 --> 00:34:13,800 astrobiologists coming to the meeting 1005 00:34:17,210 --> 00:34:15,480 there there's so much diversity so many 1006 00:34:19,129 --> 00:34:17,220 young people who are finding their way 1007 00:34:21,230 --> 00:34:19,139 into the field and finding that you know 1008 00:34:22,909 --> 00:34:21,240 that there are people who are willing to 1009 00:34:25,310 --> 00:34:22,919 open gates for them and help them along 1010 00:34:26,869 --> 00:34:25,320 the way and we certainly need more of 1011 00:34:29,990 --> 00:34:26,879 that we need more people to hold those 1012 00:34:31,369 --> 00:34:30,000 gates open to allow others to realize 1013 00:34:33,290 --> 00:34:31,379 that they belong in this field and the 1014 00:34:34,970 --> 00:34:33,300 field is very open for them 1015 00:34:36,470 --> 00:34:34,980 um some of those older models of what 1016 00:34:38,329 --> 00:34:36,480 science has to be and how it has to be 1017 00:34:40,490 --> 00:34:38,339 conducted it's nice to see some of that 1018 00:34:41,810 --> 00:34:40,500 that ideology kind of passing away a 1019 00:34:43,190 --> 00:34:41,820 little bit 1020 00:34:45,530 --> 00:34:43,200 um so let's let's think about your work 1021 00:34:47,690 --> 00:34:45,540 as a graduate student what is the best 1022 00:34:50,450 --> 00:34:47,700 part of your job 1023 00:34:53,030 --> 00:34:50,460 um honestly I Love Field work like 1024 00:34:55,129 --> 00:34:53,040 um I love getting out into Hot Springs I 1025 00:34:57,890 --> 00:34:55,139 love going to the desert and looking at 1026 00:34:59,210 --> 00:34:57,900 these ancient fossils you know and um it 1027 00:35:01,670 --> 00:34:59,220 really excites me because you know we 1028 00:35:03,470 --> 00:35:01,680 you know and we had the NASA and Esa 1029 00:35:06,170 --> 00:35:03,480 instrument science teens for 1030 00:35:09,410 --> 00:35:06,180 perseverance in the Mars 2020 Rovers um 1031 00:35:11,450 --> 00:35:09,420 out on site in 2019 and watching these 1032 00:35:14,390 --> 00:35:11,460 you know esteemed engineers and 1033 00:35:16,130 --> 00:35:14,400 scientists look at these fossils um 1034 00:35:18,109 --> 00:35:16,140 um you know like a move some of us to 1035 00:35:20,510 --> 00:35:18,119 tears you know it's amazing to see the 1036 00:35:22,130 --> 00:35:20,520 oldest evidence of life in the world you 1037 00:35:23,810 --> 00:35:22,140 know and obviously there's other more 1038 00:35:25,910 --> 00:35:23,820 contentious places like up in Greenland 1039 00:35:27,650 --> 00:35:25,920 and elsewhere but in the pilba in 1040 00:35:29,750 --> 00:35:27,660 Western Australia you can put your 1041 00:35:32,450 --> 00:35:29,760 finger on this rock and say this is as 1042 00:35:34,069 --> 00:35:32,460 far back as we can go uh and I think 1043 00:35:35,630 --> 00:35:34,079 that's that's incredible and being to be 1044 00:35:38,210 --> 00:35:35,640 able to share that with people is really 1045 00:35:39,290 --> 00:35:38,220 really amazing that was very cool and I 1046 00:35:41,329 --> 00:35:39,300 was very much in line with my next 1047 00:35:43,430 --> 00:35:41,339 question which is honestly my favorite 1048 00:35:45,829 --> 00:35:43,440 of this entire segment 1049 00:35:49,490 --> 00:35:45,839 um what is an unbelievable science fact 1050 00:35:51,950 --> 00:35:49,500 that still blows your mind 1051 00:35:54,770 --> 00:35:51,960 no definitely I think one that 1052 00:35:57,770 --> 00:35:54,780 um science coincidence I guess is the 1053 00:35:59,930 --> 00:35:57,780 relative sizes of the Moon to the Sun so 1054 00:36:01,670 --> 00:35:59,940 the moons you know sorry the Sun so much 1055 00:36:03,470 --> 00:36:01,680 further away than the moon but then you 1056 00:36:06,170 --> 00:36:03,480 can have a total eclipse where they end 1057 00:36:08,030 --> 00:36:06,180 up overlapping perfectly and it's just 1058 00:36:10,250 --> 00:36:08,040 this weird coincidence no one's 1059 00:36:12,770 --> 00:36:10,260 explained to me whether it was impacted 1060 00:36:14,630 --> 00:36:12,780 by any kind of um you know there's no 1061 00:36:16,069 --> 00:36:14,640 reason for that and as you know the 1062 00:36:18,349 --> 00:36:16,079 moon's slowly drifting away from Earth 1063 00:36:19,310 --> 00:36:18,359 because of the Collision so at one point 1064 00:36:20,750 --> 00:36:19,320 it's not going to happen but we're 1065 00:36:24,290 --> 00:36:20,760 living in a beautiful time in the world 1066 00:36:26,290 --> 00:36:24,300 where they line up perfectly and um that 1067 00:36:29,270 --> 00:36:26,300 just blows my mind it's insane yeah 1068 00:36:32,750 --> 00:36:29,280 absolutely it's it's striking like we 1069 00:36:34,849 --> 00:36:32,760 live in a very unique era in the age of 1070 00:36:36,950 --> 00:36:34,859 our Earth where we actually can have a 1071 00:36:38,810 --> 00:36:36,960 full solar eclipse 1072 00:36:40,430 --> 00:36:38,820 um you know and they have a short time 1073 00:36:42,589 --> 00:36:40,440 left you know geologically speaking that 1074 00:36:43,609 --> 00:36:42,599 that will be happening so and it's very 1075 00:36:45,230 --> 00:36:43,619 intriguing 1076 00:36:46,670 --> 00:36:45,240 um so thank you very much um I I will 1077 00:36:48,950 --> 00:36:46,680 open it up now to the audience questions 1078 00:36:50,329 --> 00:36:48,960 as well and I thank you so much for our 1079 00:36:51,530 --> 00:36:50,339 audience for asking asking questions if 1080 00:36:54,470 --> 00:36:51,540 you're watching on YouTube right now 1081 00:36:55,730 --> 00:36:54,480 please keep asking questions we're going 1082 00:37:00,849 --> 00:36:55,740 to start with a question from Twitter 1083 00:37:03,950 --> 00:37:00,859 from Ishida Verma at Virginia Verma O2 1084 00:37:06,230 --> 00:37:03,960 Ishida says hi my question is is it 1085 00:37:08,750 --> 00:37:06,240 possible for water in the hot springs to 1086 00:37:11,630 --> 00:37:08,760 get contaminated by pollutants from 1087 00:37:13,250 --> 00:37:11,640 human activities 1088 00:37:17,030 --> 00:37:13,260 um yeah that's a really good question 1089 00:37:19,310 --> 00:37:17,040 and that definitely can happen so in um 1090 00:37:21,349 --> 00:37:19,320 my long muzzled career I actually worked 1091 00:37:23,750 --> 00:37:21,359 as an environmental consultant so I 1092 00:37:26,329 --> 00:37:23,760 spent time looking at how pollution from 1093 00:37:28,370 --> 00:37:26,339 mainly like leaking petrol tanks from 1094 00:37:29,990 --> 00:37:28,380 pfas which is like a firefighting foam 1095 00:37:31,370 --> 00:37:30,000 used in airports can get into 1096 00:37:33,410 --> 00:37:31,380 groundwater 1097 00:37:34,910 --> 00:37:33,420 um it can be a big issue in a lot of 1098 00:37:37,069 --> 00:37:34,920 places 1099 00:37:38,390 --> 00:37:37,079 um definitely in Hot Springs as well one 1100 00:37:41,630 --> 00:37:38,400 interesting thing of Hot Springs as well 1101 00:37:43,370 --> 00:37:41,640 is that because the underground plumbing 1102 00:37:44,930 --> 00:37:43,380 of all these different veins in advance 1103 00:37:46,849 --> 00:37:44,940 getting it towards the surface can be 1104 00:37:49,849 --> 00:37:46,859 quite fragile it's not just you know 1105 00:37:52,490 --> 00:37:49,859 chemical pollution but also um Drilling 1106 00:37:54,710 --> 00:37:52,500 in that area if you remove the pressure 1107 00:37:56,930 --> 00:37:54,720 that's built up of all that water that's 1108 00:37:58,609 --> 00:37:56,940 thin that's water Surface by you know 1109 00:38:01,670 --> 00:37:58,619 extracting that water out somewhere else 1110 00:38:04,430 --> 00:38:01,680 entire Hot Springs shut down and die so 1111 00:38:06,109 --> 00:38:04,440 in New Zealand um they had one kind of 1112 00:38:07,910 --> 00:38:06,119 really sad case of this really early on 1113 00:38:09,470 --> 00:38:07,920 you know 40 50 years ago when they first 1114 00:38:11,630 --> 00:38:09,480 started trying to extract this hot water 1115 00:38:13,550 --> 00:38:11,640 but since then they've got really good 1116 00:38:14,930 --> 00:38:13,560 at figuring out just how much water can 1117 00:38:16,550 --> 00:38:14,940 they take off 1118 00:38:18,109 --> 00:38:16,560 um you know and use it for energy or use 1119 00:38:20,150 --> 00:38:18,119 that steam to do all the different kinds 1120 00:38:21,890 --> 00:38:20,160 of things or extract you know minerals 1121 00:38:23,329 --> 00:38:21,900 out of that water but still preserving 1122 00:38:25,130 --> 00:38:23,339 those hot springs I'm not saying that 1123 00:38:27,230 --> 00:38:25,140 all kinds of 1124 00:38:29,870 --> 00:38:27,240 um drilling or you know human 1125 00:38:31,609 --> 00:38:29,880 contamination can be bad just to be very 1126 00:38:33,349 --> 00:38:31,619 careful with it and be very 1127 00:38:34,910 --> 00:38:33,359 um particular about how you work in 1128 00:38:37,370 --> 00:38:34,920 those spaces because they are fragile 1129 00:38:39,230 --> 00:38:37,380 and really beautiful yeah absolutely and 1130 00:38:41,630 --> 00:38:39,240 honestly like you know a scientist we 1131 00:38:43,609 --> 00:38:41,640 have to be aware that you know it's not 1132 00:38:45,349 --> 00:38:43,619 just all of life on Earth I can tell you 1133 00:38:46,670 --> 00:38:45,359 my samples it's us too 1134 00:38:48,349 --> 00:38:46,680 um you know I was a graduate student I 1135 00:38:50,450 --> 00:38:48,359 pulled out my beard hairs and ran them 1136 00:38:52,670 --> 00:38:50,460 on every single instrument that I had in 1137 00:38:54,290 --> 00:38:52,680 the laboratory just to make sure that I 1138 00:38:55,370 --> 00:38:54,300 wasn't contaminating samples with beard 1139 00:38:57,710 --> 00:38:55,380 hair 1140 00:38:59,810 --> 00:38:57,720 um and then in the U.S like places like 1141 00:39:01,490 --> 00:38:59,820 up in Yellowstone National Park has some 1142 00:39:03,470 --> 00:39:01,500 of the most you know just amazing hot 1143 00:39:04,970 --> 00:39:03,480 springs on the planet and yet you know 1144 00:39:06,290 --> 00:39:04,980 you see garbage for you know from people 1145 00:39:07,849 --> 00:39:06,300 walking on these boardwalks and just 1146 00:39:09,410 --> 00:39:07,859 throwing their garbage off into these 1147 00:39:12,589 --> 00:39:09,420 hot springs and it's it's very 1148 00:39:13,910 --> 00:39:12,599 frustrating as a scientist happening but 1149 00:39:15,890 --> 00:39:13,920 we also have to know that we had it's 1150 00:39:17,930 --> 00:39:15,900 very difficult to disentangle sometimes 1151 00:39:20,030 --> 00:39:17,940 those signals from what we're looking at 1152 00:39:22,250 --> 00:39:20,040 and so it is good to collect some data 1153 00:39:25,190 --> 00:39:22,260 sometimes of those other things 1154 00:39:26,510 --> 00:39:25,200 um yeah so I agree entirely yeah it's a 1155 00:39:28,310 --> 00:39:26,520 great little anecdote on that and I 1156 00:39:29,270 --> 00:39:28,320 think this is great for anyone doing 1157 00:39:31,010 --> 00:39:29,280 science 1158 00:39:33,589 --> 00:39:31,020 um we had a geology Professor here at 1159 00:39:35,270 --> 00:39:33,599 Uni that was trying to sample gold in 1160 00:39:36,170 --> 00:39:35,280 Cyprus so this is like an island in you 1161 00:39:38,569 --> 00:39:36,180 know the 1162 00:39:40,609 --> 00:39:38,579 um Mediterranean and they had you're 1163 00:39:42,109 --> 00:39:40,619 collecting soil samples and rock samples 1164 00:39:43,849 --> 00:39:42,119 from all over the you know hundreds and 1165 00:39:45,770 --> 00:39:43,859 hundreds of samples and there was one 1166 00:39:48,109 --> 00:39:45,780 geologist who would always find the 1167 00:39:50,030 --> 00:39:48,119 mouse crazy amounts of gold in all of 1168 00:39:51,890 --> 00:39:50,040 their rocks and it ended up they didn't 1169 00:39:53,270 --> 00:39:51,900 take their gold wedding ring off and it 1170 00:39:55,069 --> 00:39:53,280 was rubbing on all the rocks that they 1171 00:39:57,050 --> 00:39:55,079 picked up and they just got these insane 1172 00:39:58,490 --> 00:39:57,060 amount of spikes and I think that's a 1173 00:40:00,829 --> 00:39:58,500 really nice anecdote I always tell 1174 00:40:02,510 --> 00:40:00,839 because you know the way the clothes you 1175 00:40:05,210 --> 00:40:02,520 wear the way you pick up a rock anything 1176 00:40:06,290 --> 00:40:05,220 like that can um bias your science and 1177 00:40:08,329 --> 00:40:06,300 you've got to be aware of that when 1178 00:40:09,829 --> 00:40:08,339 you're trying to you know figure out how 1179 00:40:13,010 --> 00:40:09,839 to do science without that kind of 1180 00:40:15,050 --> 00:40:13,020 contamination yeah absolutely it's true 1181 00:40:16,730 --> 00:40:15,060 for like Mars now for for collecting and 1182 00:40:18,170 --> 00:40:16,740 sending samples back from Mars right now 1183 00:40:20,450 --> 00:40:18,180 with perseverance it's an issue we have 1184 00:40:21,650 --> 00:40:20,460 to consider contamination if we find 1185 00:40:23,690 --> 00:40:21,660 things that look like they could be life 1186 00:40:24,890 --> 00:40:23,700 is it Earth life is it contamination 1187 00:40:27,589 --> 00:40:24,900 from the laboratory those are very 1188 00:40:29,569 --> 00:40:27,599 important questions as well 1189 00:40:32,150 --> 00:40:29,579 so our next question for you Luke comes 1190 00:40:35,750 --> 00:40:32,160 again from Twitter uh this from from Dr 1191 00:40:38,210 --> 00:40:35,760 Jim pass uh at astrosocialology gym pass 1192 00:40:40,910 --> 00:40:38,220 is the the founder and director of the 1193 00:40:42,290 --> 00:40:40,920 Astro sociology Research Institute and 1194 00:40:44,329 --> 00:40:42,300 he loves to watch our show he usually 1195 00:40:47,810 --> 00:40:44,339 asks questions related to the humanities 1196 00:40:50,210 --> 00:40:47,820 and sociology of astrobiology so Jim's 1197 00:40:51,589 --> 00:40:50,220 question is this uh since scientists 1198 00:40:53,690 --> 00:40:51,599 still disagree about the definition of 1199 00:40:55,849 --> 00:40:53,700 life on Earth how does that increase the 1200 00:40:58,069 --> 00:40:55,859 difficulty of isolating extraterrestrial 1201 00:40:59,750 --> 00:40:58,079 life beyond Earth and how do the social 1202 00:41:01,730 --> 00:40:59,760 sciences and Humanities contribute to 1203 00:41:04,310 --> 00:41:01,740 this difficulty 1204 00:41:06,650 --> 00:41:04,320 um no definitely I think that's um a 1205 00:41:08,150 --> 00:41:06,660 great question I've been I follow Jim on 1206 00:41:08,990 --> 00:41:08,160 Twitter as well and I love the way they 1207 00:41:10,430 --> 00:41:09,000 view 1208 00:41:12,950 --> 00:41:10,440 um the importance of these Humanities 1209 00:41:15,069 --> 00:41:12,960 and sociology in the work we do 1210 00:41:17,630 --> 00:41:15,079 um so firstly on the definition for life 1211 00:41:19,190 --> 00:41:17,640 uh definitely you know NASA's got its 1212 00:41:20,930 --> 00:41:19,200 definition that they came up with but 1213 00:41:23,390 --> 00:41:20,940 there's obviously um issues with that 1214 00:41:25,310 --> 00:41:23,400 and it's always a fun part of any you 1215 00:41:27,770 --> 00:41:25,320 know intro to astrology course it's like 1216 00:41:29,630 --> 00:41:27,780 well if life has to be 1217 00:41:32,150 --> 00:41:29,640 um reproducing or you know being able to 1218 00:41:33,530 --> 00:41:32,160 replicate what about a sterile mule or 1219 00:41:35,510 --> 00:41:33,540 you know like what about this or that 1220 00:41:37,670 --> 00:41:35,520 like you can always have fun um ways 1221 00:41:39,950 --> 00:41:37,680 thinking about that kind of stuff 1222 00:41:42,470 --> 00:41:39,960 um I 1223 00:41:44,390 --> 00:41:42,480 think that the sociology and Humanities 1224 00:41:46,609 --> 00:41:44,400 can come into play with that because I 1225 00:41:47,870 --> 00:41:46,619 think artists and people working in 1226 00:41:51,470 --> 00:41:47,880 those social space they're a lot better 1227 00:41:53,750 --> 00:41:51,480 holding multiple and sometimes opposing 1228 00:41:55,250 --> 00:41:53,760 ideas you know you think you go to an 1229 00:41:58,370 --> 00:41:55,260 artist you go to someone studying 1230 00:42:00,170 --> 00:41:58,380 sociology or like philosophy and there's 1231 00:42:02,270 --> 00:42:00,180 all these different ideas and I have to 1232 00:42:04,370 --> 00:42:02,280 take them in and there's someone's more 1233 00:42:07,190 --> 00:42:04,380 than one answer or maybe the answers are 1234 00:42:08,510 --> 00:42:07,200 unsolvable and I think the way that they 1235 00:42:10,430 --> 00:42:08,520 can hold that information is very broad 1236 00:42:12,050 --> 00:42:10,440 whereas a scientist you know it's very 1237 00:42:13,310 --> 00:42:12,060 much reduction it's like what's the one 1238 00:42:14,990 --> 00:42:13,320 single answer like what is the 1239 00:42:17,390 --> 00:42:15,000 definition what can I write down in my 1240 00:42:18,950 --> 00:42:17,400 little book you know and I think that as 1241 00:42:20,690 --> 00:42:18,960 scientists we have a lot to learn from 1242 00:42:23,210 --> 00:42:20,700 sociologists and from other people 1243 00:42:25,970 --> 00:42:23,220 outside of our field and learning how to 1244 00:42:27,790 --> 00:42:25,980 hold that Nuance because you know we may 1245 00:42:30,589 --> 00:42:27,800 find life that is totally 1246 00:42:32,270 --> 00:42:30,599 uncomprehendable you know we may be 1247 00:42:34,910 --> 00:42:32,280 looking at it not even know what it is 1248 00:42:35,630 --> 00:42:34,920 you know and I think that 1249 00:42:40,010 --> 00:42:35,640 um 1250 00:42:42,109 --> 00:42:40,020 has to offer especially arts and social 1251 00:42:43,910 --> 00:42:42,119 sciences to get around those kind of 1252 00:42:45,950 --> 00:42:43,920 interesting problems 1253 00:42:48,010 --> 00:42:45,960 yeah absolutely 1254 00:42:50,990 --> 00:42:48,020 um our next question comes from aruniver 1255 00:42:52,370 --> 00:42:51,000 who's now watching on YouTube it's very 1256 00:42:54,109 --> 00:42:52,380 similar to our previous question so 1257 00:42:55,370 --> 00:42:54,119 aruniverse says uh different 1258 00:42:56,750 --> 00:42:55,380 contaminants have been found in 1259 00:42:59,569 --> 00:42:56,760 environments like in the Arctic and 1260 00:43:02,089 --> 00:42:59,579 Antarctic which also host analog sites 1261 00:43:04,010 --> 00:43:02,099 uh can these contaminants affect your 1262 00:43:05,809 --> 00:43:04,020 research on Hot Springs 1263 00:43:07,010 --> 00:43:05,819 um and so I'm going to extrapolate a bit 1264 00:43:08,950 --> 00:43:07,020 more from that too since we've already 1265 00:43:11,990 --> 00:43:08,960 discussed contamination from a human 1266 00:43:13,309 --> 00:43:12,000 behaviors I'm also curious you know for 1267 00:43:14,329 --> 00:43:13,319 the hot spring sites that you've studied 1268 00:43:17,390 --> 00:43:14,339 and maybe even those that you haven't 1269 00:43:18,470 --> 00:43:17,400 but you you kind of know of well not 1270 00:43:20,930 --> 00:43:18,480 just issues with like human 1271 00:43:23,329 --> 00:43:20,940 contamination but like geological change 1272 00:43:24,650 --> 00:43:23,339 through time do you think we're missing 1273 00:43:26,809 --> 00:43:24,660 anything when it comes to our 1274 00:43:28,910 --> 00:43:26,819 understanding of Hot Springs especially 1275 00:43:29,990 --> 00:43:28,920 ancient Hot Springs maybe you know maybe 1276 00:43:31,309 --> 00:43:30,000 they're under a different temperature 1277 00:43:33,770 --> 00:43:31,319 regime than we really can understand 1278 00:43:35,510 --> 00:43:33,780 because you know magmas were or hotter 1279 00:43:36,829 --> 00:43:35,520 in the early Earth history and things 1280 00:43:39,410 --> 00:43:36,839 like that is there anything you think 1281 00:43:41,030 --> 00:43:39,420 specifically in hot spring research that 1282 00:43:42,890 --> 00:43:41,040 we're missing out on 1283 00:43:46,190 --> 00:43:42,900 um yeah no that's a really good um 1284 00:43:48,170 --> 00:43:46,200 question yeah thanks to that so that's a 1285 00:43:50,630 --> 00:43:48,180 um a concept that we come up with a lot 1286 00:43:52,490 --> 00:43:50,640 because basically you know where I study 1287 00:43:54,230 --> 00:43:52,500 a modern hot spring and I think hey how 1288 00:43:55,849 --> 00:43:54,240 can we apply this to 1289 00:43:58,250 --> 00:43:55,859 um our understanding of how life formed 1290 00:43:59,990 --> 00:43:58,260 on Earth four billion years ago but Hot 1291 00:44:01,430 --> 00:44:00,000 Springs would have changed massively you 1292 00:44:03,589 --> 00:44:01,440 know and I think that's a lot of the 1293 00:44:05,150 --> 00:44:03,599 research we do is how would these Hot 1294 00:44:07,069 --> 00:44:05,160 Springs looked 1295 00:44:08,510 --> 00:44:07,079 um with early life so we can go back to 1296 00:44:10,609 --> 00:44:08,520 you know three and a half billion years 1297 00:44:11,630 --> 00:44:10,619 ago and see hot springs they did have 1298 00:44:13,370 --> 00:44:11,640 life in them but it was just 1299 00:44:15,589 --> 00:44:13,380 stromatolites are just very simple you 1300 00:44:17,270 --> 00:44:15,599 know a little microbial mats and that 1301 00:44:19,190 --> 00:44:17,280 kind of stuff and then going back from 1302 00:44:21,109 --> 00:44:19,200 there so that's some research that um 1303 00:44:23,030 --> 00:44:21,119 I'm about to publish at the moment is 1304 00:44:25,670 --> 00:44:23,040 all around looking at 1305 00:44:27,710 --> 00:44:25,680 how would Prebiotic Organics so that's 1306 00:44:30,170 --> 00:44:27,720 organic molecules before the Earth 1307 00:44:31,609 --> 00:44:30,180 formed life impacted these hot springs 1308 00:44:33,470 --> 00:44:31,619 and you know there would have been 1309 00:44:34,970 --> 00:44:33,480 meteorites dropping all kinds of 1310 00:44:36,410 --> 00:44:34,980 Organics down in Earth and all other 1311 00:44:38,510 --> 00:44:36,420 kinds of 1312 00:44:40,730 --> 00:44:38,520 um you know Fisher trough synthesis like 1313 00:44:42,650 --> 00:44:40,740 Organics being cooked Up From Below in 1314 00:44:44,690 --> 00:44:42,660 these Hot Springs how would that make 1315 00:44:46,910 --> 00:44:44,700 different minerals more or less soluble 1316 00:44:48,890 --> 00:44:46,920 how would that make different 1317 00:44:50,690 --> 00:44:48,900 um rocks form you know if there's all 1318 00:44:52,250 --> 00:44:50,700 these you know sugars of ribose or 1319 00:44:54,349 --> 00:44:52,260 carbohydrates or proteins floating 1320 00:44:56,690 --> 00:44:54,359 around and then again you know when you 1321 00:44:58,670 --> 00:44:56,700 look at these um great experiments like 1322 00:45:01,130 --> 00:44:58,680 um Dave Dima pouring a cup of Prebiotic 1323 00:45:02,510 --> 00:45:01,140 soup into a hot spring up in kamchako 1324 00:45:05,630 --> 00:45:02,520 and Russia and seeing what comes out 1325 00:45:08,030 --> 00:45:05,640 obviously there's all kinds of cells and 1326 00:45:10,250 --> 00:45:08,040 Organics and things in there as well and 1327 00:45:12,109 --> 00:45:10,260 um I they would definitely skew your 1328 00:45:13,309 --> 00:45:12,119 information you know how much so we 1329 00:45:15,470 --> 00:45:13,319 don't know yet that's definitely 1330 00:45:17,329 --> 00:45:15,480 something to consider so yeah the 1331 00:45:18,530 --> 00:45:17,339 impacts of Modern Life will definitely 1332 00:45:21,050 --> 00:45:18,540 change what we're looking at and it's 1333 00:45:22,010 --> 00:45:21,060 important to remember that interesting 1334 00:45:23,569 --> 00:45:22,020 yeah 1335 00:45:25,670 --> 00:45:23,579 um our next question comes from a 1336 00:45:28,309 --> 00:45:25,680 previous guest uh Bruce damer is 1337 00:45:30,950 --> 00:45:28,319 watching on YouTube right now and he has 1338 00:45:32,870 --> 00:45:30,960 a pretty funny question he says what do 1339 00:45:36,470 --> 00:45:32,880 you think about the idea of a protocell 1340 00:45:39,230 --> 00:45:36,480 superhero uh it asked the deepest common 1341 00:45:41,329 --> 00:45:39,240 ancestor as a comic book character maybe 1342 00:45:42,650 --> 00:45:41,339 fighting all forces of degradation and 1343 00:45:45,890 --> 00:45:42,660 the second law of Thermodynamics to 1344 00:45:48,829 --> 00:45:47,390 um I love that and I think that's you 1345 00:45:50,870 --> 00:45:48,839 know I've 1346 00:45:53,210 --> 00:45:50,880 um had the great privilege of working uh 1347 00:45:55,849 --> 00:45:53,220 with Bruce and Dave scientifically but I 1348 00:45:57,890 --> 00:45:55,859 also um when I was over at the um 1349 00:45:59,750 --> 00:45:57,900 University of California in Santa Cruz 1350 00:46:01,910 --> 00:45:59,760 doing my little you know placement there 1351 00:46:04,250 --> 00:46:01,920 for my PhD I got to stay with Bruce so 1352 00:46:06,710 --> 00:46:04,260 we had all these amazing fun 1353 00:46:08,809 --> 00:46:06,720 um wacky conversations about the world 1354 00:46:11,809 --> 00:46:08,819 and Science and everything so um always 1355 00:46:14,690 --> 00:46:11,819 great ideas like the um protocell 1356 00:46:16,790 --> 00:46:14,700 superhero I know NASA does a comic book 1357 00:46:18,829 --> 00:46:16,800 series um and it's really around the 1358 00:46:20,150 --> 00:46:18,839 formation of the science and the people 1359 00:46:21,770 --> 00:46:20,160 involved 1360 00:46:23,510 --> 00:46:21,780 um and actually I met I forget their 1361 00:46:25,790 --> 00:46:23,520 name but I met them at abscicond they're 1362 00:46:26,930 --> 00:46:25,800 graphic artists who um draws them in 1363 00:46:29,030 --> 00:46:26,940 their brilliant artist and a really 1364 00:46:31,690 --> 00:46:29,040 interesting person maybe we can make 1365 00:46:33,650 --> 00:46:31,700 some yeah like hot spring 1366 00:46:35,930 --> 00:46:33,660 superheroes I don't know maybe there's 1367 00:46:39,410 --> 00:46:35,940 something there we can um get involved 1368 00:46:41,930 --> 00:46:39,420 in yeah I I have I have to grab one off 1369 00:46:44,690 --> 00:46:41,940 my wall here I happen to have the most 1370 00:46:48,950 --> 00:46:44,700 recent issue of the astrobiology graphic 1371 00:46:51,490 --> 00:46:48,960 histories from Dr Aaron gronstall so uh 1372 00:46:54,410 --> 00:46:51,500 Aaron is not just a comic book artist 1373 00:46:56,270 --> 00:46:54,420 he's also a PhD geochemist 1374 00:46:58,849 --> 00:46:56,280 um and so you know it's interesting that 1375 00:47:00,829 --> 00:46:58,859 you know Aaron also like many of us has 1376 00:47:02,329 --> 00:47:00,839 these other facets of his career not 1377 00:47:04,730 --> 00:47:02,339 just being in geochemistry and 1378 00:47:07,970 --> 00:47:04,740 astrobiology he's also an incredible 1379 00:47:09,109 --> 00:47:07,980 artist and so our next question comes 1380 00:47:11,569 --> 00:47:09,119 from one of our production assistants 1381 00:47:14,329 --> 00:47:11,579 and actually ties into this very well uh 1382 00:47:17,030 --> 00:47:14,339 honor of mahanti uh has asked that 1383 00:47:18,410 --> 00:47:17,040 connecting science with stand-up comedy 1384 00:47:20,030 --> 00:47:18,420 um sounds a lot like stepping out of 1385 00:47:21,410 --> 00:47:20,040 your comfort zone 1386 00:47:22,970 --> 00:47:21,420 um and you know maybe in some ways it's 1387 00:47:24,349 --> 00:47:22,980 like stepping from you know geochemistry 1388 00:47:26,690 --> 00:47:24,359 into artwork 1389 00:47:28,849 --> 00:47:26,700 um and things like that so honorrup asks 1390 00:47:30,710 --> 00:47:28,859 what are some other areas that you want 1391 00:47:31,790 --> 00:47:30,720 to explore 1392 00:47:34,690 --> 00:47:31,800 um and that you would recommend other 1393 00:47:36,290 --> 00:47:34,700 scientists maybe explore as well 1394 00:47:38,990 --> 00:47:36,300 interesting 1395 00:47:41,150 --> 00:47:39,000 um and so firstly yes it was the most 1396 00:47:44,270 --> 00:47:41,160 terrifying thing I've done in my entire 1397 00:47:46,069 --> 00:47:44,280 life like stand-up comedy was 1398 00:47:48,170 --> 00:47:46,079 um horrendously 1399 00:47:50,450 --> 00:47:48,180 um yeah just like the stage fright was 1400 00:47:52,190 --> 00:47:50,460 so real but also so exciting and having 1401 00:47:55,069 --> 00:47:52,200 all these people laugh at your jokes and 1402 00:47:56,750 --> 00:47:55,079 applaud and it was um yeah exhilarating 1403 00:47:58,309 --> 00:47:56,760 I guess is a way to describe it no but 1404 00:48:00,109 --> 00:47:58,319 definitely I had to step out of my 1405 00:48:01,490 --> 00:48:00,119 comfort zone for that 1406 00:48:03,770 --> 00:48:01,500 um I think that's quite a personal 1407 00:48:05,690 --> 00:48:03,780 question so I'd say firstly for other 1408 00:48:08,329 --> 00:48:05,700 scientists out there I don't want to 1409 00:48:10,370 --> 00:48:08,339 tell you what you know passion or hobby 1410 00:48:11,990 --> 00:48:10,380 to link up together that's up to you you 1411 00:48:14,870 --> 00:48:12,000 know like what excites you do you really 1412 00:48:16,370 --> 00:48:14,880 enjoy cooking do you really enjoy 1413 00:48:18,349 --> 00:48:16,380 um a sport do you really enjoy what 1414 00:48:20,390 --> 00:48:18,359 other hobbies that interests you 1415 00:48:23,270 --> 00:48:20,400 um I think that's where you should be 1416 00:48:24,710 --> 00:48:23,280 excited because I think the reason these 1417 00:48:25,849 --> 00:48:24,720 things work the reason that the Comedy 1418 00:48:28,010 --> 00:48:25,859 Works so well is because I was 1419 00:48:29,390 --> 00:48:28,020 passionate about it and I would get up 1420 00:48:30,589 --> 00:48:29,400 there and I would apply for funding and 1421 00:48:31,790 --> 00:48:30,599 I would convince people and I would 1422 00:48:33,890 --> 00:48:31,800 really I'll get on the phone and call 1423 00:48:35,329 --> 00:48:33,900 venues and I'm like hey you need us 1424 00:48:37,490 --> 00:48:35,339 there because we're gonna blow your 1425 00:48:39,410 --> 00:48:37,500 socks off you know like and I think if I 1426 00:48:40,910 --> 00:48:39,420 wasn't driven by it if I was just trying 1427 00:48:42,230 --> 00:48:40,920 to find 1428 00:48:43,970 --> 00:48:42,240 um practically just a way to do my 1429 00:48:45,349 --> 00:48:43,980 science communication better it wouldn't 1430 00:48:47,990 --> 00:48:45,359 have worked so I definitely think you 1431 00:48:48,890 --> 00:48:48,000 need that personal passion um for myself 1432 00:48:51,589 --> 00:48:48,900 I'm actually really interested in 1433 00:48:53,270 --> 00:48:51,599 exploring dance more I'm really um I 1434 00:48:55,250 --> 00:48:53,280 love dancing 1435 00:48:57,109 --> 00:48:55,260 um you know either at a club or you know 1436 00:48:58,970 --> 00:48:57,119 I do a little bit of like contemporary 1437 00:49:00,410 --> 00:48:58,980 dance and like kind of like very 1438 00:49:01,849 --> 00:49:00,420 embodied 1439 00:49:04,309 --> 00:49:01,859 um movement and kind of figuring out 1440 00:49:06,890 --> 00:49:04,319 what my body does and reacts to stuff 1441 00:49:08,630 --> 00:49:06,900 yoga all that kind of movement practices 1442 00:49:11,690 --> 00:49:08,640 um so yeah maybe when I've got more time 1443 00:49:13,910 --> 00:49:11,700 after my PhD I might um yeah look more 1444 00:49:15,290 --> 00:49:13,920 into dance and how that kind of infects 1445 00:49:18,109 --> 00:49:15,300 the way that I think about the world 1446 00:49:19,609 --> 00:49:18,119 that yeah who knows oh that's groovy 1447 00:49:21,290 --> 00:49:19,619 yeah I mean I love dancing myself who 1448 00:49:24,589 --> 00:49:21,300 knows maybe we'll create our own Dance 1449 00:49:26,569 --> 00:49:24,599 troupe the dancing astrobiologist 1450 00:49:27,710 --> 00:49:26,579 um so here's here's another fun joke for 1451 00:49:30,650 --> 00:49:27,720 our viewers 1452 00:49:32,809 --> 00:49:30,660 um so tell me why are geologists good at 1453 00:50:03,530 --> 00:49:32,819 stand-up comedy 1454 00:50:07,490 --> 00:50:05,450 yeah definitely so I think the best way 1455 00:50:09,829 --> 00:50:07,500 to track me down is on Twitter so if you 1456 00:50:11,329 --> 00:50:09,839 go to add Stellar
