1 00:00:05,539 --> 00:00:03,530 the belly inequality could be violated 2 00:00:07,460 --> 00:00:05,549 and quantum physics could stay intact if 3 00:00:08,600 --> 00:00:07,470 you allowed particles to communicate 4 00:00:10,370 --> 00:00:08,610 with each other faster than the speed of 5 00:00:13,129 --> 00:00:10,380 light now this would violate special 6 00:00:16,189 --> 00:00:13,139 relativity but quantum mechanics would 7 00:00:17,900 --> 00:00:16,199 still be left intact and the notion that 8 00:00:19,790 --> 00:00:17,910 there is an underlying reality would be 9 00:00:21,170 --> 00:00:19,800 left intact if you allowed particles 10 00:00:23,599 --> 00:00:21,180 communicate with each other faster than 11 00:00:25,939 --> 00:00:23,609 the speed of light well as it turns out 12 00:00:27,589 --> 00:00:25,949 the legged inequality sort of takes away 13 00:00:29,630 --> 00:00:27,599 the last amount of freedom last degree 14 00:00:31,550 --> 00:00:29,640 of freedom that was still left over in 15 00:00:34,220 --> 00:00:31,560 the bell in equality that I was just 16 00:00:36,470 --> 00:00:34,230 talking about and this is a diagram of 17 00:00:38,299 --> 00:00:36,480 the legged inequality taken from New 18 00:00:39,619 --> 00:00:38,309 Scientist magazine it's a fairly 19 00:00:42,410 --> 00:00:39,629 complicated one and that you're not 20 00:00:44,240 --> 00:00:42,420 measuring simply a spin here and a spin 21 00:00:46,130 --> 00:00:44,250 there from entangled particles you're 22 00:00:47,990 --> 00:00:46,140 taking entangled particles measuring the 23 00:00:49,190 --> 00:00:48,000 spin here a spin there and then you're 24 00:00:50,869 --> 00:00:49,200 measuring three elliptical polarization 25 00:00:53,360 --> 00:00:50,879 angles I don't want to go into that in 26 00:00:54,470 --> 00:00:53,370 part because it would be way above the 27 00:00:55,729 --> 00:00:54,480 level of this talk and secondly because 28 00:00:57,770 --> 00:00:55,739 I don't fully understand this yet 29 00:00:59,990 --> 00:00:57,780 because this has not been clarified in 30 00:01:02,510 --> 00:01:00,000 any qualitative way in the article a new 31 00:01:04,429 --> 00:01:02,520 scientist nor in the anything I've found 32 00:01:06,080 --> 00:01:04,439 since that has given me an adequate 33 00:01:07,789 --> 00:01:06,090 explanation for what this what the 34 00:01:10,700 --> 00:01:07,799 details of this are but the point is 35 00:01:11,899 --> 00:01:10,710 that it's been hailed as the both by the 36 00:01:13,070 --> 00:01:11,909 group in Vienna that made the 37 00:01:16,450 --> 00:01:13,080 measurement at my New Scientist magazine 38 00:01:21,219 --> 00:01:16,460 as pretty much ruling out not only 39 00:01:23,330 --> 00:01:21,229 nonlocality but also realism as a 40 00:01:26,060 --> 00:01:23,340 explanation for how particles can be 41 00:01:28,569 --> 00:01:26,070 correlated with each other and yet 42 00:01:30,980 --> 00:01:28,579 quantum mechanics predicts that the 43 00:01:32,170 --> 00:01:30,990 relationships between these measurements 44 00:01:34,490 --> 00:01:32,180 that you make are rather different 45 00:01:35,660 --> 00:01:34,500 quantum mechanically than they are if 46 00:01:37,700 --> 00:01:35,670 you assume that the particles could 47 00:01:39,230 --> 00:01:37,710 communicate with each other or that they 48 00:01:40,609 --> 00:01:39,240 would be if the particles really have 49 00:01:42,440 --> 00:01:40,619 these properties and you're simply 50 00:01:43,609 --> 00:01:42,450 measuring them but you're not creating 51 00:01:44,749 --> 00:01:43,619 anything when you make the measurement 52 00:01:50,569 --> 00:01:44,759 you're making a real objective 53 00:01:51,679 --> 00:01:50,579 measurement so recent experiments led by 54 00:01:53,179 --> 00:01:51,689 the group at the University of Vienna 55 00:01:55,219 --> 00:01:53,189 Austria provide the most compelling 56 00:01:57,889 --> 00:01:55,229 evidence yet that there is no objective 57 00:02:00,499 --> 00:01:57,899 reality beyond what we observe so it's 58 00:02:03,139 --> 00:02:00,509 really the observation the observation 59 00:02:04,969 --> 00:02:03,149 that creates the reality what they found 60 00:02:07,520 --> 00:02:04,979 is that legate's in equality is violated 61 00:02:09,589 --> 00:02:07,530 as well as bells even if you allow for 62 00:02:11,540 --> 00:02:09,599 instantaneous influences quantum 63 00:02:14,089 --> 00:02:11,550 measurements do not fit with the idea of 64 00:02:14,360 --> 00:02:14,099 an objective reality so as they say in 65 00:02:20,000 --> 00:02:14,370 the 66 00:02:21,320 --> 00:02:20,010 it we in fact create reality now if 67 00:02:23,750 --> 00:02:21,330 quantum theory denies a straightforward 68 00:02:25,100 --> 00:02:23,760 physical reality of atoms it would also 69 00:02:26,990 --> 00:02:25,110 seem to deny the straightforward 70 00:02:29,330 --> 00:02:27,000 physical reality of chairs which are 71 00:02:31,339 --> 00:02:29,340 made of atoms now we like to think that 72 00:02:33,559 --> 00:02:31,349 the world can be divided into quantum 73 00:02:35,539 --> 00:02:33,569 and classical realms and in fact that's 74 00:02:38,420 --> 00:02:35,549 sort of the way physics operates 75 00:02:41,360 --> 00:02:38,430 practically but in fact there really is 76 00:02:44,119 --> 00:02:41,370 you know only one reality here and the 77 00:02:47,599 --> 00:02:44,129 transition from quantum to macro reality 78 00:02:50,360 --> 00:02:47,609 is not not a real one in fact it's not 79 00:02:53,270 --> 00:02:50,370 not even really blurry it's there's one 80 00:02:55,250 --> 00:02:53,280 continuous law of physics and it takes 81 00:02:56,750 --> 00:02:55,260 us from one level to the other you can 82 00:02:58,539 --> 00:02:56,760 have quantum object objects that are 83 00:03:00,860 --> 00:02:58,549 very large for example there is a 84 00:03:02,720 --> 00:03:00,870 gravitational wave detecting bar that 85 00:03:04,640 --> 00:03:02,730 weighs about a ton that has to be 86 00:03:06,289 --> 00:03:04,650 analyzed using quantum mechanics because 87 00:03:08,210 --> 00:03:06,299 of the the precision of what you're 88 00:03:12,890 --> 00:03:08,220 looking for and the precision of 89 00:03:15,619 --> 00:03:12,900 knowledge of the the the well of that 90 00:03:17,390 --> 00:03:15,629 bar itself so a quantum objects not 91 00:03:20,349 --> 00:03:17,400 necessarily one that's tiny it can be a 92 00:03:24,020 --> 00:03:20,359 huge thing the size of a well one ton 93 00:03:25,640 --> 00:03:24,030 barbell prior to the legged experiment 94 00:03:26,839 --> 00:03:25,650 was thought that observation one object 95 00:03:28,819 --> 00:03:26,849 and instantaneous influence behavior 96 00:03:30,530 --> 00:03:28,829 another object another one is greatly 97 00:03:32,509 --> 00:03:30,540 distant even though physical force 98 00:03:34,449 --> 00:03:32,519 connects the two well it's even more 99 00:03:36,440 --> 00:03:34,459 mysterious now because what these 100 00:03:38,089 --> 00:03:36,450 experiments are telling us the leg 101 00:03:41,569 --> 00:03:38,099 experiments is a consciousness creating 102 00:03:43,430 --> 00:03:41,579 both realities the observation now the 103 00:03:45,080 --> 00:03:43,440 the last thing that is a rather 104 00:03:48,170 --> 00:03:45,090 mysterious about quantum physics and 105 00:03:49,339 --> 00:03:48,180 this ruling out of the notion that the 106 00:03:51,229 --> 00:03:49,349 particles can communicate with each 107 00:03:52,640 --> 00:03:51,239 other or that there is some realism in 108 00:03:54,830 --> 00:03:52,650 the particles that were measuring rather 109 00:03:56,089 --> 00:03:54,840 than being created at the point of 110 00:03:58,339 --> 00:03:56,099 measurement at the moment of measurement 111 00:04:02,539 --> 00:03:58,349 is that the observation also creates it 112 00:04:07,520 --> 00:04:02,549 back history it's possible for objects 113 00:04:10,580 --> 00:04:07,530 to say this is a wheeler time delay 114 00:04:15,319 --> 00:04:10,590 experiment that I'm thinking of if you 115 00:04:16,789 --> 00:04:15,329 let a save a quantum object encounter a 116 00:04:19,159 --> 00:04:16,799 with an effectively a beam splitter 117 00:04:21,170 --> 00:04:19,169 where it can be divided and go along two 118 00:04:23,480 --> 00:04:21,180 possible paths then there are two things 119 00:04:25,909 --> 00:04:23,490 that can happen if the object splits in 120 00:04:27,920 --> 00:04:25,919 half and goes along two paths then it's 121 00:04:29,779 --> 00:04:27,930 possible that these two 122 00:04:31,070 --> 00:04:29,789 as when the obvious emerge will 123 00:04:32,990 --> 00:04:31,080 interfere with each other and you get an 124 00:04:34,520 --> 00:04:33,000 interference pattern and so if you get 125 00:04:36,680 --> 00:04:34,530 an interference pattern then you know 126 00:04:38,420 --> 00:04:36,690 that the object has been split at some 127 00:04:41,900 --> 00:04:38,430 point and gone off along two parallel 128 00:04:44,600 --> 00:04:41,910 paths and therefore this shows the 129 00:04:46,850 --> 00:04:44,610 interference pattern that that is a 130 00:04:48,379 --> 00:04:46,860 signature of that having happened the 131 00:04:50,270 --> 00:04:48,389 alternative is that the particle can go 132 00:04:52,279 --> 00:04:50,280 along one path or the other and you can 133 00:04:54,379 --> 00:04:52,289 then detect which path it emerges from 134 00:04:55,760 --> 00:04:54,389 when you make your measurement but 135 00:04:58,550 --> 00:04:55,770 whether you whether the particle goes 136 00:05:00,409 --> 00:04:58,560 along one path splits and then along 137 00:05:02,570 --> 00:05:00,419 both of them and interferes or whether 138 00:05:07,100 --> 00:05:02,580 it goes along a path doesn't split but 139 00:05:09,140 --> 00:05:07,110 goes along a or b that depends upon what 140 00:05:10,550 --> 00:05:09,150 measurement you make down here so you 141 00:05:12,260 --> 00:05:10,560 determine down here when you make the 142 00:05:14,140 --> 00:05:12,270 measurement what the particle does back 143 00:05:17,180 --> 00:05:14,150 here when it reaches the beam splitter 144 00:05:19,010 --> 00:05:17,190 well in fact what you've done is sort of 145 00:05:21,260 --> 00:05:19,020 created backwards in time causation 146 00:05:23,540 --> 00:05:21,270 because the object has to do what you 147 00:05:25,760 --> 00:05:23,550 measure if you decide to detect which 148 00:05:27,290 --> 00:05:25,770 slit the object comes out of then it's 149 00:05:29,180 --> 00:05:27,300 not possible for that object to is split 150 00:05:31,070 --> 00:05:29,190 in two back here because that's not 151 00:05:32,779 --> 00:05:31,080 consistent with what you measure if you 152 00:05:34,189 --> 00:05:32,789 make a measurement that gets an 153 00:05:35,510 --> 00:05:34,199 interference pattern then that 154 00:05:37,430 --> 00:05:35,520 demonstrates that the object has gone 155 00:05:39,439 --> 00:05:37,440 along two paths after it's gone through 156 00:05:41,750 --> 00:05:39,449 the beam splitter but the object of that 157 00:05:43,250 --> 00:05:41,760 back here it's possible for you to not 158 00:05:44,689 --> 00:05:43,260 make your decision on which measurement 159 00:05:45,920 --> 00:05:44,699 you're going to make until after the 160 00:05:48,110 --> 00:05:45,930 object has passed that point of no 161 00:05:50,180 --> 00:05:48,120 return so once again it's the 162 00:05:52,040 --> 00:05:50,190 observation that creates the reality and 163 00:05:55,580 --> 00:05:52,050 in fact even creates the back history 164 00:05:58,040 --> 00:05:55,590 for that reality so the point of all 165 00:05:59,270 --> 00:05:58,050 this is that and certainly looks as if 166 00:06:01,909 --> 00:05:59,280 there's evidence coming out of the 167 00:06:04,010 --> 00:06:01,919 physics lab not for God but for the 168 00:06:06,140 --> 00:06:04,020 notion that consciousness is creating 169 00:06:07,969 --> 00:06:06,150 reality at the level of quantum physics 170 00:06:10,820 --> 00:06:07,979 and if it's creating reality at level of 171 00:06:12,350 --> 00:06:10,830 quantum physics then by implication the 172 00:06:14,540 --> 00:06:12,360 rest of reality sama also is being 173 00:06:16,189 --> 00:06:14,550 created by consciousness and I think 174 00:06:17,960 --> 00:06:16,199 consciousness is actually the the 175 00:06:19,399 --> 00:06:17,970 formative element behind the universe 176 00:06:20,899 --> 00:06:19,409 it's not that somehow it's an 177 00:06:22,969 --> 00:06:20,909 epiphenomenon coming out of our brains 178 00:06:24,710 --> 00:06:22,979 and on a matter of biochemistry taking 179 00:06:26,629 --> 00:06:24,720 place in here but rather its 180 00:06:28,339 --> 00:06:26,639 consciousness it is the ultimate reality 181 00:06:30,860 --> 00:06:28,349 out of which everything else has come 182 00:06:32,390 --> 00:06:30,870 and that is my explanation for why the 183 00:06:33,830 --> 00:06:32,400 universe is finely tuned it's not 184 00:06:35,510 --> 00:06:33,840 certainly a proof by any means if you 185 00:06:37,190 --> 00:06:35,520 want to go away from this talk thinking 186 00:06:39,050 --> 00:06:37,200 there is a multiverse of universes and 187 00:06:40,879 --> 00:06:39,060 ours is not special we're just one of an 188 00:06:41,810 --> 00:06:40,889 ensemble that's fine it's equally 189 00:06:43,580 --> 00:06:41,820 logical it's equally 190 00:06:45,590 --> 00:06:43,590 rational but I don't think it has any 191 00:06:48,530 --> 00:06:45,600 advantage over the notion that has cost 192 00:07:08,090 --> 00:06:48,540 us all the way behind the universe thank 193 00:07:14,360 --> 00:07:08,100 you okay we have a nice long time for 194 00:07:19,910 --> 00:07:14,370 questions um and okay i'll start with 195 00:07:22,400 --> 00:07:19,920 the guy i saw first my name is Kenny 196 00:07:26,530 --> 00:07:22,410 Arnett I'm wondering what happens on a 197 00:07:32,080 --> 00:07:26,540 lifeless planet to quantum mechanics 198 00:07:36,920 --> 00:07:34,460 there having been on life was fine it i 199 00:07:38,390 --> 00:07:36,930 don't know you've raised a good you've 200 00:07:41,360 --> 00:07:38,400 raised a question though that i think 201 00:07:42,800 --> 00:07:41,370 deserves an answer let me open up my 202 00:07:43,940 --> 00:07:42,810 computer again because after all I've 203 00:07:47,050 --> 00:07:43,950 got about a couple of minutes of extra 204 00:07:49,790 --> 00:07:47,060 time because I went early didn't I so 205 00:07:53,990 --> 00:07:49,800 let's see if i can find slide here that 206 00:07:55,580 --> 00:07:54,000 i prepared as possible response to a 207 00:08:01,100 --> 00:07:55,590 question that might have come up like 208 00:08:04,010 --> 00:08:01,110 that the von Neumann chain the question 209 00:08:06,170 --> 00:08:04,020 is do you really need an observer or can 210 00:08:08,900 --> 00:08:06,180 anything and anything that interacts 211 00:08:10,910 --> 00:08:08,910 with a quantum situation constitute a 212 00:08:12,860 --> 00:08:10,920 measurement and this question looked at 213 00:08:15,110 --> 00:08:12,870 rather carefully back in 1932 already by 214 00:08:16,940 --> 00:08:15,120 john von neumann john vannoy minh was a 215 00:08:19,220 --> 00:08:16,950 mathematical genius he was one of the 216 00:08:22,460 --> 00:08:19,230 people that invented the the operator 217 00:08:24,470 --> 00:08:22,470 analysis of quantum mechanics the 218 00:08:28,970 --> 00:08:24,480 operator operator formalism of quantum 219 00:08:30,500 --> 00:08:28,980 mechanics and when he showed was that 220 00:08:32,360 --> 00:08:30,510 quantum theory makes physics encounters 221 00:08:33,980 --> 00:08:32,370 with consciousness inevitable so he 222 00:08:35,450 --> 00:08:33,990 considered an apparatus a measuring 223 00:08:38,240 --> 00:08:35,460 apparatus like a Geiger counter he said 224 00:08:41,540 --> 00:08:38,250 ok now that Geiger counter whether it 225 00:08:45,370 --> 00:08:41,550 goes off or not let's see for a second 226 00:08:49,960 --> 00:08:45,380 here huh take some measuring apparatus 227 00:08:52,250 --> 00:08:49,970 that would look at whether or not say a 228 00:08:55,639 --> 00:08:52,260 quantum event is happening in a given 229 00:08:58,519 --> 00:08:55,649 box and you can argue well that guy girl 230 00:08:59,749 --> 00:08:58,529 measurement is really equivalent to an 231 00:09:01,460 --> 00:08:59,759 observer looking at that the Geiger 232 00:09:02,749 --> 00:09:01,470 counter of course is not conscious so 233 00:09:04,850 --> 00:09:02,759 kind of Geiger counter substitute for a 234 00:09:07,639 --> 00:09:04,860 human being his answer was no what 235 00:09:10,999 --> 00:09:07,649 happens at the Geiger counters the 236 00:09:14,059 --> 00:09:11,009 Geiger counters state becomes becomes 237 00:09:16,220 --> 00:09:14,069 entangled with the state of the quantum 238 00:09:18,019 --> 00:09:16,230 situations trying to measure if you then 239 00:09:20,389 --> 00:09:18,029 try to put a detector to measure whether 240 00:09:22,579 --> 00:09:20,399 the Geiger counter has registered or not 241 00:09:24,530 --> 00:09:22,589 then that detector becomes entangled 242 00:09:26,239 --> 00:09:24,540 with become superimposed with quantum 243 00:09:27,350 --> 00:09:26,249 mechanically with a Geiger counter the 244 00:09:29,299 --> 00:09:27,360 detected with a Geiger counter the 245 00:09:31,429 --> 00:09:29,309 Geiger counter with a quantum object and 246 00:09:33,230 --> 00:09:31,439 the whole thing forms a chain and the 247 00:09:35,900 --> 00:09:33,240 chain is not broken until a conscious 248 00:09:37,160 --> 00:09:35,910 observer decides to make a measurement 249 00:09:38,299 --> 00:09:37,170 and I see a hand going up in the back 250 00:09:40,489 --> 00:09:38,309 there's probably going to challenge that 251 00:09:42,590 --> 00:09:40,499 interpretation but this anointment chain 252 00:09:44,059 --> 00:09:42,600 is that the explanation or the 253 00:09:45,530 --> 00:09:44,069 rationalization or the rationale I 254 00:09:47,869 --> 00:09:45,540 should say I suppose more realistically 255 00:09:50,119 --> 00:09:47,879 the rationale for why it really takes an 256 00:09:53,720 --> 00:09:50,129 observer to make a quantum event happen 257 00:09:59,090 --> 00:09:53,730 and to break the well bring about the
