1 00:00:00,000 --> 00:00:10,160 You know what? I've been around for a while. I've traveled the world, met some interesting 2 00:00:10,160 --> 00:00:16,400 people, done some crazy things. So you might just think there's not much that could take 3 00:00:16,400 --> 00:00:25,200 me by surprise. You'd be wrong. The world is full of stories and science and things 4 00:00:25,200 --> 00:00:31,000 that amaze and confound me every single day. Incredible mysteries that keep me awake at 5 00:00:31,000 --> 00:00:41,000 night. Some I can answer. Others justify logic. Can people move from the present into the 6 00:00:41,000 --> 00:00:45,840 past or future? Eyewitnesses report a woman materializing from thin air. Could she be 7 00:00:45,840 --> 00:00:54,040 a time traveler? An ancient stone structure suggests the incredible. Did ancient pagan 8 00:00:54,040 --> 00:01:01,840 worshippers practice human sacrifice in New Hampshire? Plants seem to possess strange powers, 9 00:01:01,840 --> 00:01:11,120 allowing them to detect human thought. Are they sentient beings with dark intent? Yep. 10 00:01:12,120 --> 00:01:18,120 It's a weird world. And I love it. 11 00:01:18,120 --> 00:01:42,880 One minute. I'm sorry. I just... I couldn't put this book down. The Time Machine, written 12 00:01:42,880 --> 00:01:49,360 in 1895 by H.T. Wells. With this one book, a hot new science fiction genre was born. The 13 00:01:49,360 --> 00:01:55,680 Time Travel Story. Now, of course, there are endless books and films and TV shows on the 14 00:01:55,680 --> 00:02:03,180 subject and the mind-boggling paradoxes of journeying across time. Great stuff. Shame the concept 15 00:02:03,180 --> 00:02:08,880 of time travel is just fiction, isn't it? 16 00:02:09,880 --> 00:02:18,480 On July 15th, 2006, famed science fiction author Whitley Streber, best known for his books 17 00:02:18,480 --> 00:02:24,400 The Hunger and Communion, was out at the theater with his wife Anne and her friend Starfire 18 00:02:24,400 --> 00:02:30,000 Tor. Little did they know what would happen that night would rival anything found in 19 00:02:30,000 --> 00:02:34,560 Whitley's books. Nothing seems impossible to me anymore. I haven't talked about it very 20 00:02:34,560 --> 00:02:39,000 much. After dinner, Anne and her friend went into what they thought was an empty ladies' 21 00:02:39,000 --> 00:02:46,840 room. It's a very small room, about 10 by 12. There was nobody in that room except for 22 00:02:46,840 --> 00:02:53,800 Anne Streber and myself. So I was standing on these steps. No one went in it after the 23 00:02:53,800 --> 00:02:59,480 two of them went in it. I was watching the entire time. Anne was a little bit before me 24 00:02:59,840 --> 00:03:04,560 and she left and said she would wait for me outside. So I went outside, stood in front 25 00:03:04,560 --> 00:03:10,560 of the door waiting for Starfire. As I slightly rounded the corner, coming out of the stall, 26 00:03:10,560 --> 00:03:20,280 a woman just materialized. She didn't seem to understand where she was. She seemed confused 27 00:03:20,280 --> 00:03:30,360 and then she just left the room. While I was standing there, a woman came out. I go out 28 00:03:30,360 --> 00:03:36,640 the door to the ladies' room and Anne Streber rushes up to me very, very excited. She says, 29 00:03:36,640 --> 00:03:41,080 a lady came out but she didn't go in, a lady came out but she didn't go in. This was pretty 30 00:03:41,080 --> 00:03:47,840 amazing because we knew no one was in there when we went in. So how could someone have 31 00:03:47,880 --> 00:03:53,520 come out who was never in there in the first place? No one, absolutely no one went in that 32 00:03:53,520 --> 00:04:01,520 bathroom. Who was this mysterious woman and how could she have appeared from nowhere? For 33 00:04:01,520 --> 00:04:10,280 the eyewitnesses, this is no ghost story. For them, the answer is much weirder. Something 34 00:04:10,280 --> 00:04:18,360 altered the timelines we were brought together like a bad edit of a film and that's how 35 00:04:18,360 --> 00:04:25,160 we almost collided. Right. Two women go into an empty bathroom and three women come out. 36 00:04:25,160 --> 00:04:32,760 Is it really possible this mystery woman slipped through from another time? Is that weird or 37 00:04:32,760 --> 00:04:42,440 what? I say that's the weirdest, weirder what yet. Yeah, it's pretty far out but remarkably, 38 00:04:42,440 --> 00:04:48,520 time travel may indeed be possible and proof could soon be found in a 17-mile tunnel deep 39 00:04:48,520 --> 00:04:55,560 underground at the border of France and Switzerland. This is the large Hadron Collider, a 17-mile long 40 00:04:55,560 --> 00:05:01,920 tunnel designed to smash atoms together in an attempt to recreate conditions that last existed 41 00:05:02,080 --> 00:05:08,320 just before the Big Bang when the universe was less than a trillionth of a second old. 42 00:05:10,080 --> 00:05:15,280 Scientists at the LHC are trying to understand what happened in that critical moment to make 43 00:05:15,280 --> 00:05:22,240 our universe what it is. By solving this, they hope to shed light on some of the most fundamental 44 00:05:22,240 --> 00:05:29,440 unanswered questions in physics. With the large Hadron Collider, perhaps one day we'll be able 45 00:05:29,440 --> 00:05:34,960 to answer these cosmic questions. What happened before the Big Bang? Is it possible to go through 46 00:05:34,960 --> 00:05:42,560 a black hole? Can you bend time into a pretzel? We're now entering the cusp, the cusp of human 47 00:05:42,560 --> 00:05:47,920 progress. A hundred years ago, think how primitive we are. A hundred years from now, think of how 48 00:05:47,920 --> 00:05:53,120 advanced computers, artificial intelligence will be. Right now we're at the most interesting point 49 00:05:53,120 --> 00:05:59,280 in human history, the cusp, when we're going to just walk it through the universe. A complete 50 00:05:59,280 --> 00:06:05,120 understanding of how the entire universe is really constructed might enable future physicists 51 00:06:05,120 --> 00:06:11,760 to find a way to manipulate the fabric of space, time itself, and travel into the past or future. 52 00:06:12,480 --> 00:06:18,720 But can we really manipulate time? To find out, we first need to investigate the time itself. 53 00:06:19,120 --> 00:06:28,880 Isaac Newton imagined time as an arrow, always traveling straightforward in one direction. 54 00:06:30,000 --> 00:06:36,960 But then Albert Einstein came along and said that time is more like a river that can meander, 55 00:06:36,960 --> 00:06:44,400 flow at different speeds, and even eddy back upon itself. Now we look at a river and we think of 56 00:06:44,560 --> 00:06:51,440 the spot on the river where we are is something like the present moment. And then upstream from us 57 00:06:51,440 --> 00:06:57,280 is the future. This is coming towards us, it's relentless, it's sort of inevitable. In a moment, 58 00:06:57,280 --> 00:07:02,880 what was up there is going to be here. And downstream from us, we can think of as the past. So these 59 00:07:02,880 --> 00:07:07,920 are events that have already happened. So there you have it. You've got the future, you've got the 60 00:07:07,920 --> 00:07:14,960 present moment, you've got the past. Is it possible to go against the flow of time into the future? 61 00:07:15,600 --> 00:07:18,640 Or move even further downstream into the past? 62 00:07:21,680 --> 00:07:28,560 Going back in time is simple, theoretically. All we need to do is beat light to its destination, 63 00:07:28,560 --> 00:07:35,840 travel faster than light speed. How fast is that? Well, as Albert Einstein figured out, 64 00:07:35,840 --> 00:07:43,440 light travels at a fixed and constant speed throughout the universe of 186,000 miles per second. 65 00:07:45,440 --> 00:07:51,120 And the space shuttle can travel around five miles per second, so we have a bit of a problem. 66 00:07:52,960 --> 00:07:59,520 But our hopes of meeting our ancestors aren't over yet. Modern physicists have built on 67 00:07:59,600 --> 00:08:05,520 Einstein's theories and discovered that although we may not be able to beat light in a head-to-head 68 00:08:05,520 --> 00:08:12,800 race, we might be able to cheat and take a shortcut. Going back in time is simple, theoretically. 69 00:08:13,920 --> 00:08:18,640 To do this, a time traveler would need to bend the fabric of space, connecting two 70 00:08:18,640 --> 00:08:24,960 distant points to create a theoretical tunnel through space and time known as a wormhole. 71 00:08:25,200 --> 00:08:32,320 There are two parallel universes. Perhaps it might be possible to build a gateway between these 72 00:08:32,320 --> 00:08:39,600 universes, a wormhole, a shortcut, like the looking glass of Alice. Think of Alice in Wonderland. 73 00:08:39,600 --> 00:08:45,520 She had a looking glass and she put her hand through it, and her hand went to the other side 74 00:08:45,520 --> 00:08:51,920 of forever. That is a wormhole. But could we manipulate the very fabric of time and space? 75 00:08:52,240 --> 00:08:59,120 If we have something called negative matter or negative energy, it might be possible to build 76 00:08:59,120 --> 00:09:05,840 a gateway to another universe, a gateway to another point in space or time. Now, of course, 77 00:09:05,840 --> 00:09:11,360 in science fiction, we have the dilithium crystals of Star Trek. People talk about spice. 78 00:09:11,360 --> 00:09:16,720 People talk about other exotic chemicals that will open these gateways. Well, my physicist, 79 00:09:16,720 --> 00:09:22,480 to us, it's negative matter or negative energy. Negative energy we can actually create in the 80 00:09:22,480 --> 00:09:28,480 laboratory. It's already been done, but only in microscopic quantities. Negative matter we've 81 00:09:28,480 --> 00:09:34,400 never seen before. If we can find a negative matter meteorite in outer space, just perhaps, 82 00:09:34,400 --> 00:09:40,400 maybe we can harness it to open a gateway to another universe. The only problem is the amount 83 00:09:40,400 --> 00:09:45,680 of energy required to punch a hole to the other side of the universe is impossible for us to 84 00:09:45,680 --> 00:09:54,160 achieve with our current technology. The trick is to assemble enough positive and negative energy 85 00:09:54,800 --> 00:10:01,360 in order to rip open the fabric of space and time. That's really hard. We're talking about the energy 86 00:10:01,360 --> 00:10:08,320 of a black hole, the energy of a star, in order to bend time into a pretzel. What do you mean it's 87 00:10:08,320 --> 00:10:12,080 impractical to go back in time? Can't make a wormhole. What's wrong with these eggheads? 88 00:10:12,320 --> 00:10:18,720 Okay, so traveling into the past might be a tad beyond our reach, but here's something surprising. 89 00:10:19,600 --> 00:10:27,680 Most physicists believe it's possible, relatively easy in fact, to travel into the future. 90 00:10:29,440 --> 00:10:33,680 How do you exploit Einstein's theory of relativity to travel into the future? Well, 91 00:10:33,680 --> 00:10:36,880 it turns out it's not that hard to do. Now, it's hard from an engineering point of view, 92 00:10:36,880 --> 00:10:41,120 you just need a really fast spaceship, which we don't have. But if you had one, here's what you 93 00:10:41,120 --> 00:10:47,200 do. You just go on a long journey and come back home. Remarkably, this is possible because time 94 00:10:47,200 --> 00:10:54,240 behaves differently when an object or person travels at high velocity. It's called time dilation. 95 00:10:55,440 --> 00:11:01,200 If you move fast enough, your clock will disagree from a clock that's been left at home. A similar 96 00:11:01,200 --> 00:11:05,600 thing can happen if you spend a lot of time in a strong gravitational field, like near a black hole, 97 00:11:05,600 --> 00:11:13,680 for example. This amazing feat has actually already been accomplished. Russian cosmonaut 98 00:11:13,680 --> 00:11:18,000 Sergey Krikalev has spent more time in space than any other human being. 99 00:11:19,680 --> 00:11:28,160 From 1988 to 2005, Krikalev spent 803 days orbiting the Earth at high speed. 100 00:11:28,560 --> 00:11:36,160 At times, Krikalev was traveling at 17,000 miles per hour, nowhere near the speed of light, 101 00:11:36,160 --> 00:11:39,440 but fast enough to travel forward in time. 102 00:11:42,160 --> 00:11:47,520 It's only about one-fiftyth of a second, so it's almost too small to even notice. But he has aged 103 00:11:47,520 --> 00:11:52,240 just a little bit less than, let's say, if he had had a twin brother who would stay on the ground, 104 00:11:52,240 --> 00:11:54,720 he's just a little bit younger than his brother would have been. 105 00:11:55,680 --> 00:12:00,080 Using this theory, it may be possible to travel thousands of years into the future. 106 00:12:01,360 --> 00:12:06,160 Imagine traveling all the way around the circumference of the Milky Way galaxy, our galaxy. 107 00:12:06,160 --> 00:12:11,200 Now, it's very big. It's about 150,000 light-years around. So it's going to take a long time. 108 00:12:11,200 --> 00:12:17,440 You start accelerating at a rate of 1g, which is the normal force of gravity that you feel 109 00:12:17,440 --> 00:12:21,440 just sitting here. So you have this very mild acceleration, but you keep it up long enough. 110 00:12:21,680 --> 00:12:25,600 You're eventually going very fast. When you get halfway around, you start decelerating, 111 00:12:25,600 --> 00:12:29,280 and after many, many more years, you end up back on Earth where you started from. 112 00:12:30,000 --> 00:12:35,760 Here's the thing. To someone who has stayed at home and just watched you go and is waiting 113 00:12:35,760 --> 00:12:40,400 for your return, they have a long wait, because it's going to take 150,000 years before you 114 00:12:40,400 --> 00:12:47,200 come back. But for you, from your point of view, on board this spaceship, only 23 years will have passed. 115 00:12:47,440 --> 00:12:52,800 So, although it seems impossible, time travel is, theoretically at least, real. 116 00:12:54,400 --> 00:13:02,320 And the large Hadron Collider could yet witness science fiction become functioning science fact. 117 00:13:05,280 --> 00:13:10,000 In some theories, where there's extra dimensions of space, in addition to the 118 00:13:10,160 --> 00:13:18,880 three that we see, little compact, tiny dimensions, extra dimensions of space, 119 00:13:19,840 --> 00:13:28,880 there's a speculative idea that they may be able to make a mini black hole in the large Hadron Collider. 120 00:13:31,200 --> 00:13:35,280 So is it possible the mystery figure that appeared that night in Los Angeles 121 00:13:35,360 --> 00:13:42,080 was really a time traveler? Perhaps even from a future where science had finally answered 122 00:13:42,080 --> 00:13:48,080 the secrets of the universe and were now able to manipulate time? Could be. 123 00:13:49,760 --> 00:13:55,120 We physicists believe that if time travel is possible, all the paradoxes can be resolved 124 00:13:55,120 --> 00:14:01,840 if a parallel reality opens up and there are no contradictions. You simply change the past 125 00:14:01,840 --> 00:14:09,760 of another universe. This also means that perhaps in the future, our descendants may have the energy 126 00:14:09,760 --> 00:14:15,920 and the ability to create a time machine. So one day, if somebody knocks on your door and claims to 127 00:14:15,920 --> 00:14:24,560 be your great-great-great-great-great-great-great-granddaughter, don't slam the door. Is that weird or what? 128 00:14:32,080 --> 00:14:45,600 A mysterious set of stone structures in rural New Hampshire. Could this be a place of pagan worship 129 00:14:45,600 --> 00:14:52,480 and human sacrifice thousands of years old? The astronomical alignments are one of the 130 00:14:52,480 --> 00:14:59,200 key pieces of evidence to cite as ancient. Does this mean ancient Europeans crossed the Atlantic 131 00:14:59,200 --> 00:15:03,760 thousands of years before Columbus? So it really does open up a whole different way to look at 132 00:15:03,760 --> 00:15:11,200 North American history. What is this place? Who built it? And what could its existence mean for America? 133 00:15:13,280 --> 00:15:21,520 Truth in history, it would say, is a sliding scale. The facts that we know today may all crumble 134 00:15:21,520 --> 00:15:26,880 away with discoveries of tomorrow and those discoveries are often to be uncovered in the 135 00:15:26,880 --> 00:15:33,280 most unlikely of places. For example, could an innocent-looking pile of rocks tucked away in the 136 00:15:33,280 --> 00:15:40,800 corner of a farmer's field in the northeastern United States challenge everything we think we 137 00:15:40,800 --> 00:15:47,440 know about American history? What if the first European to arrive in North America wasn't Christopher 138 00:15:47,440 --> 00:15:53,760 Columbus or even a Viking? What if instead of coming to New England in search of religious freedom, 139 00:15:53,760 --> 00:15:59,040 the first European settlers came to practice human sacrifice? 140 00:16:01,280 --> 00:16:08,320 In Sanham, New Hampshire, the mysterious grouping of megalithic stones standing 14 feet high 141 00:16:08,320 --> 00:16:14,400 surround a compound that houses a maze of eight-foot-long chambers and crypts set into the ground. 142 00:16:15,760 --> 00:16:21,360 The centerpiece, a huge stone slab that looks like a sacrificial table. 143 00:16:21,840 --> 00:16:27,840 This is Dennis Stone. His family has owned the site for three generations and he has an amazing 144 00:16:27,840 --> 00:16:34,560 theory. Stone believes that this is the oldest man-made structure in the entire United States. 145 00:16:37,360 --> 00:16:40,640 The American Stonehenge may be one of the more important archaeological sites in the Western 146 00:16:40,640 --> 00:16:46,480 Hemisphere. There are different theories of who built the site. If it is in fact ancient and was 147 00:16:46,480 --> 00:16:51,760 built by old world people, this would demonstrate that people crossed the Atlantic Ocean a few 148 00:16:51,760 --> 00:16:57,520 thousand years before Christopher Columbus or even the Vikings came to America. Sounds crazy, 149 00:16:57,520 --> 00:17:03,680 doesn't it? The very idea that explorers predating Columbus by millennia might have crossed the 150 00:17:03,680 --> 00:17:12,320 Atlantic and made America their home? Well, before you dismiss the idea, consider this. It was only 151 00:17:12,400 --> 00:17:19,680 in 1960 that the Norwegian archaeologist Ann Ingstad was ridiculed when she proposed her idea that 152 00:17:19,680 --> 00:17:26,400 Vikings had settled North America in the 12th century, but it turned out to be true. 153 00:17:26,400 --> 00:17:32,640 Ingstad's discovery changed history and the Viking settlement she found in Newfoundland, 154 00:17:32,640 --> 00:17:36,720 Canada is now an official World Heritage Site. 155 00:17:36,720 --> 00:17:43,520 Could this structure have been built by mysterious ancient travelers? Stone believes 156 00:17:43,520 --> 00:17:49,840 similarities between his site and archaeological sites in Europe hold the key to uncovering the truth. 157 00:17:51,840 --> 00:17:56,960 We have a couple of chambers here that are very reminiscent of chambers found in France, Ireland, 158 00:17:56,960 --> 00:18:02,400 Spain and Netherlands. One of the purposes we know of is that they're used for astronomical 159 00:18:02,480 --> 00:18:08,880 alignments with the sun, moon and stars. And they're just stone markers, the sun would rise or set 160 00:18:08,880 --> 00:18:13,680 over these stones so the moon would do the same thing. And this may have been tied into the religious 161 00:18:13,680 --> 00:18:18,720 ceremonies, the longest day of the year, the shortest day of the year, or the equinoxes. And it's also 162 00:18:18,720 --> 00:18:24,320 stones that align with cross-quarter days, days in between the seasons. The ancient Celts and other 163 00:18:24,320 --> 00:18:31,360 cultures actually set up stones which would mark these times. The Celts, a diverse group of 164 00:18:32,240 --> 00:18:39,120 tribes that dominated much of central Europe until around 1600 years ago. Stone remnants of 165 00:18:39,120 --> 00:18:43,920 Celtic structures including elaborate burial chambers can be found all over Europe. 166 00:18:46,000 --> 00:18:50,640 It has also been suggested that the Celts were involved in the construction of England's most 167 00:18:50,640 --> 00:18:58,240 famous ancient megalith stone henge. A site some believe was created as a giant astronomical tool. 168 00:18:59,200 --> 00:19:03,520 Its stones aligned to the solstice positions of the sun and moon. 169 00:19:04,800 --> 00:19:10,160 Did Celts come and settle America a thousand years before Columbus? 170 00:19:12,000 --> 00:19:19,440 In the 1970s, Barry Fowlegan, a professor at Harvard, stumbled upon a stone carved here on site 171 00:19:19,440 --> 00:19:25,040 and the kind of writing that was on the stone, something called Iberian Punic, the Iberian 172 00:19:25,040 --> 00:19:31,600 Peninsula area at that time housed the Celts. David Brody is an amateur archaeological researcher. 173 00:19:31,600 --> 00:19:37,680 He supports the idea that the Celts, not Columbus, were the first Europeans to reach the new world. 174 00:19:39,120 --> 00:19:42,560 We think of the Celts as being from Ireland, but actually they originated in Central Europe and 175 00:19:42,560 --> 00:19:47,360 then went down to the Iberian Peninsula. But it's the Celts leaving the Iberian Peninsula region 176 00:19:47,360 --> 00:19:51,120 that I think came over here and established the site in America's Stone Henge. 177 00:19:51,120 --> 00:19:58,480 This place is becoming weirder and weirder by the minute. Who the heck was it? 178 00:19:59,200 --> 00:20:02,240 Hanging around these woods all that time ago and what were they doing? 179 00:20:04,400 --> 00:20:10,160 Could this site in New England share the same purpose as the original Stone Henge in Old England? 180 00:20:10,160 --> 00:20:15,680 A prehistoric monument of huge carefully aligned stones assembled by ancient 181 00:20:16,240 --> 00:20:20,800 Britons for some mysterious pagan purpose? 182 00:20:22,960 --> 00:20:27,520 If the Celts did build this American Stone Henge as a religious site, 183 00:20:27,520 --> 00:20:33,600 then Dentistone has some striking ideas as to what ceremonies would have been performed here. 184 00:20:34,800 --> 00:20:39,280 I'm standing next to the sacrificial table. It's one of the main features at America's Stone 185 00:20:39,280 --> 00:20:45,200 Henge. This table measures about nine feet in length, six feet in width, and it sits on four 186 00:20:45,200 --> 00:20:50,800 stone legs. On the surface of the stone there's a rectangular cutout or a groove that's been 187 00:20:50,800 --> 00:20:56,240 made on the surface and it has a little runoff. So if a ceremony of some type was taken place, 188 00:20:56,240 --> 00:21:01,040 a fluid could run through the channel and then run off the stone into a base perhaps. 189 00:21:02,480 --> 00:21:06,880 Although little is directly known of the Celts' religious practices, the Romans who fought them 190 00:21:06,880 --> 00:21:12,880 and even Julius Caesar himself often described how Celtic druids or priests carried out human 191 00:21:12,880 --> 00:21:21,120 sacrifice to honor their many pagan gods. The discovery of various ancient sites of ritualized 192 00:21:21,120 --> 00:21:28,640 murder in Europe may support this. The stone table in Salem also has another even more bizarre 193 00:21:28,640 --> 00:21:37,120 feature. Dentistone calls an oracle tube. This tube goes through about eight feet, comes out 194 00:21:37,120 --> 00:21:41,760 underneath the sacrificial table. The voice would project out under the table during a ceremony 195 00:21:41,760 --> 00:21:45,760 perhaps and people would hear the voice and think it was a god or spirit talking to them. 196 00:21:46,320 --> 00:21:54,240 I am the god of the underworld. I accept your sacrifice. Remember always obey the priest. 197 00:21:55,040 --> 00:22:00,800 When we find these large elaborate stone structures historically, they were done to honor 198 00:22:01,920 --> 00:22:06,640 gods for religious purposes, whether it's the pyramids or Stonehenge in England or Notre Dame 199 00:22:06,640 --> 00:22:12,080 Cathedral in Paris. When ancient man went to the effort to build something this elaborate, 200 00:22:12,080 --> 00:22:18,240 it was done for religious purposes. And again that takes me back to the Celts perhaps 500 BC. 201 00:22:18,240 --> 00:22:22,240 That's the type of thing that they did all over Europe at that time and would have done here if 202 00:22:22,240 --> 00:22:30,720 they came to America. America settled by Iron Age Europeans. It's an explosive theory but not one 203 00:22:30,720 --> 00:22:40,320 exactly shared by many experts. Research since the 1940s has shown there's a great deal of differences 204 00:22:40,320 --> 00:22:46,400 between what we find in Ireland and what is found at this site. There are major differences in the 205 00:22:46,400 --> 00:22:51,040 architectural styles, there are differences in the engineering of how the buildings put together. 206 00:22:53,360 --> 00:22:59,200 An expert in prehistoric stone structures, James Gage, also believes that an ancient civilization 207 00:22:59,200 --> 00:23:05,200 built this place but based on carvings in the stone themselves, his theory is that the structure was 208 00:23:05,200 --> 00:23:12,000 created by a more local people, Native Americans. First and foremost is the large number of Native 209 00:23:12,000 --> 00:23:18,560 American artifacts that have been found at the site. These artifacts range from you know spraypurs 210 00:23:18,560 --> 00:23:26,560 and projectile points, stuff we normally expect, to paint cups and rubbing stones. This evidence also 211 00:23:26,560 --> 00:23:33,520 includes clay pottery that they were actually manufacturing on site. It was a small wetlands 212 00:23:33,520 --> 00:23:39,680 area where they were able to actually mine the clay and adjacent to it. They had a small area where 213 00:23:39,680 --> 00:23:46,560 they were making the pots and firing them. One of the more interesting features about this site is 214 00:23:46,560 --> 00:23:54,000 it has a number of pecked roofs, chipped out stone basins and they're all been created by 215 00:23:54,000 --> 00:24:00,000 pecking out the stone using a hammer stone and this pecking technique is very distinctive to the 216 00:24:00,000 --> 00:24:09,520 Native Americans. The Celtic culture was affiliate vans civilization, had metal tools and they were 217 00:24:09,520 --> 00:24:17,440 making gold artifacts. We would expect them to use you know more vans technology other than just simple 218 00:24:17,440 --> 00:24:24,640 hammer stones. The Native American theory makes obvious sense but not according to David Brody. 219 00:24:24,880 --> 00:24:31,040 It is possible that the Native Americans did build the America Stone Hensight. It would have been out of the 220 00:24:31,040 --> 00:24:39,040 ordinary for them to have done so so I'm not inclined to think they did. They didn't typically, Native Americans in this area of the country, did not typically build with stone. 221 00:24:39,040 --> 00:24:46,080 They had stone tools and they used stone to build their hearse but they didn't build these elaborate structures typically out of stone. 222 00:24:46,080 --> 00:24:53,680 Once in a while it was his sweat lodge but there's too many of these chambers here. In addition the Native American tribes, although a lot of their history 223 00:24:54,400 --> 00:25:01,600 hasn't wiped out in the New England region, they don't take ownership of this site like they take ownership of other sites that they believe they did build. 224 00:25:01,600 --> 00:25:09,600 So I'm not going to tell you that they didn't do it but I think the weight of the evidence is more in favor of some kind of ancient seafaring European civilization. 225 00:25:12,640 --> 00:25:17,680 So while these experts can't agree which ancient civilization built the American Stone Hensight, 226 00:25:18,640 --> 00:25:25,360 another archaeologist, Kenny Thetter, believes whoever is responsible was an ancient at all. 227 00:25:26,240 --> 00:25:30,320 Keltson, New England, 3,000 years ago, I don't think so but okay. 228 00:25:31,280 --> 00:25:38,560 Archaeological sites where people were so neat that they picked every stinking artifact up and left no physical evidence behind, not bloody likely. 229 00:25:41,280 --> 00:25:46,560 Okay, it looks like we're back to square one. So who could it have been? 230 00:25:48,320 --> 00:25:51,760 That built those incredibly weird structures. Was it the Kelts? 231 00:25:51,760 --> 00:26:00,000 Not likely. The Native Americans? Maybe not. Well how about another slightly less romantic theory? 232 00:26:02,480 --> 00:26:06,240 What if it was assembled by a couple of drunken 18th century farmers? 233 00:26:07,040 --> 00:26:17,040 If America Stone Hens is what I think it is, which is 19th century idiosyncratic structures, that doesn't make it any less important than if it's a 3,000 year old site with Kelts traipsing around in southern New England. 234 00:26:17,040 --> 00:26:23,040 Makes it of different significance but I don't think it makes it less significant. It just makes it different. 235 00:26:23,040 --> 00:26:27,680 Thetter's theory is the structures were constructed by the descendants of the Kelts. 236 00:26:27,680 --> 00:26:34,480 The better known European settlers that came in the centuries after Christopher Columbus, bringing with them traditional ways of building stone structures. 237 00:26:36,480 --> 00:26:39,200 Yeah, damn right! They were Kelts. 238 00:26:39,200 --> 00:26:42,080 They were the ones that were built by the Romans. 239 00:26:42,080 --> 00:26:45,040 They were the ones that were built by the Romans. 240 00:26:45,040 --> 00:26:49,040 Bringing with them traditional ways of building stone structures. 241 00:26:51,040 --> 00:26:59,520 Yeah, damn right! They were Kelts. But they were Kelts from the 1800s and 1700s because those are the people who moved here. 242 00:27:00,400 --> 00:27:08,400 Good point, but can't the more recent Celtic immigration theory explain the existence of the site's most macabre and enigmatic looking object? 243 00:27:09,200 --> 00:27:13,200 Why does American Stonehenge appear to have a sacrificial table? 244 00:27:13,200 --> 00:27:19,200 Look at the names of the towns, for example, in New Hampshire around where American Stonehenge is located. 245 00:27:19,200 --> 00:27:23,680 The towns and the counties. Places like London Dairy. Why is it called London Dairy? 246 00:27:23,680 --> 00:27:28,400 Because the people who lived here were from Great Britain. They were Kelts. 247 00:27:28,400 --> 00:27:32,880 These stones are found actually throughout New England so you're sort of left with a choice. 248 00:27:32,880 --> 00:27:41,360 Either there was a widespread practice of human sacrifice throughout New England or we got something else going on. 249 00:27:41,360 --> 00:27:43,360 I think it's something else that's going on. 250 00:27:43,360 --> 00:27:51,360 If you Google, Lye Stone or Cider Press Stone, you'll actually come up with some antique sites. 251 00:27:51,360 --> 00:27:53,360 They'll sell you stones like that. 252 00:27:53,360 --> 00:28:00,360 The deal is, if you know something about historical technology, that historical process, we do know that there are stones like that. 253 00:28:00,360 --> 00:28:08,360 They were used for a number of mundane purposes, not sacrificing people, but in fact making apple cider or producing lye soap. 254 00:28:08,360 --> 00:28:16,360 The deal is that an artifact like that, an object like that, is something that we in the modern world suffer from cultural amnesia. 255 00:28:16,360 --> 00:28:20,360 We don't press our own cider. We don't make lye soap anymore. 256 00:28:20,360 --> 00:28:28,360 So the objects, the artifacts from that period that any little kid would be able to make lye soap, 257 00:28:28,360 --> 00:28:32,360 today it's mysterious. 258 00:28:32,360 --> 00:28:40,360 So are the drainage grooves on the four-ton stone table actually for apple juice, not human blood? 259 00:28:40,360 --> 00:28:50,360 It may be the most plausible theory, but the mystery of the American Stonehenge cannot be cleared up quite so neatly. 260 00:28:50,360 --> 00:28:56,360 Charcoal pits at the site have been carbon dated and believed to be more than 2,000 years old. 261 00:28:56,360 --> 00:29:12,360 And Dennis Stone still believes his site is proof that an ancient people commemorated the coming of the solstices here, exactly as they may have done at the real Stonehenge. 262 00:29:13,360 --> 00:29:19,360 The astronomical alignments are one of the key pieces of evidence to site as ancient. 263 00:29:19,360 --> 00:29:25,360 The alignments do not work today. They're off a certain amount due to the Earth's tilt changing. 264 00:29:25,360 --> 00:29:32,360 In 1977 we took four years' worth of survey data. We sent it to the Hobbit Smithsonian Center for Astrophysics in Cambridge, Mass. 265 00:29:32,360 --> 00:29:40,360 They ran it through the computer and they said that if these were used for astronomical purposes they would work about 1800 BC plus or minus about 200 years. 266 00:29:41,360 --> 00:29:44,360 We have taken carbon datings on the hilltop, about 16 of them. 267 00:29:44,360 --> 00:29:50,360 In the main site, which is where we're standing right now, the oldest carbon dating was 4,000 years old. 268 00:29:50,360 --> 00:29:54,360 This agrees pretty closely to the astronomical data and results. 269 00:29:54,360 --> 00:30:02,360 American Stonehenge could be proved that ancient Europeans traveled to North America thousands of years before Columbus. 270 00:30:03,360 --> 00:30:07,360 Or it could be a rare example of Native American stone building. 271 00:30:07,360 --> 00:30:13,360 Or it's just a really weird apple cider factory built by colonial farmers. 272 00:30:15,360 --> 00:30:22,360 Only one thing is for certain. The origins and purpose of American Stonehenge remains a mystery. 273 00:30:22,360 --> 00:30:25,360 Is that weird? Or what? 274 00:30:32,360 --> 00:30:35,360 What's the secret to my success? 275 00:30:35,360 --> 00:30:40,360 I talk to my plants, I stroke them, and I give them a little tender loving care. 276 00:30:40,360 --> 00:30:45,360 Why? Because I believe plants like humans are the only ones that can be used to help. 277 00:30:45,360 --> 00:30:48,360 I'm not a human being. 278 00:30:48,360 --> 00:30:50,360 I'm not a human being. 279 00:30:50,360 --> 00:30:52,360 I'm a human being. 280 00:30:52,360 --> 00:30:54,360 I'm a human being. 281 00:30:54,360 --> 00:30:56,360 I'm a human being. 282 00:30:56,360 --> 00:30:58,360 I'm a human being. 283 00:30:58,360 --> 00:31:03,360 Loving care. Why? Because I believe plants like humans are emotional beings. 284 00:31:03,360 --> 00:31:06,360 They have feelings just like you and I do. They love. They fear. 285 00:31:06,360 --> 00:31:10,360 They can be affectionate and they can communicate. 286 00:31:10,360 --> 00:31:13,360 You don't believe? Green matter? 287 00:31:13,360 --> 00:31:16,360 Has gray matter? No? 288 00:31:16,360 --> 00:31:18,360 Well... 289 00:31:19,360 --> 00:31:22,360 Watch this. 290 00:31:22,360 --> 00:31:30,760 Of all the many different organisms that are on the planet Earth, common sense dictates 291 00:31:30,760 --> 00:31:38,280 that mammals are the most advanced, capable of thought, reasoning and emotions. 292 00:31:38,280 --> 00:31:45,120 But shocking new evidence suggests that plants may possess these abilities as well, and even 293 00:31:45,120 --> 00:31:51,280 more mysterious, they may have the power of ESP. 294 00:31:51,280 --> 00:31:55,440 Is this science fiction? 295 00:31:55,440 --> 00:31:57,520 Or science fact? 296 00:31:57,520 --> 00:32:00,400 Researchers attempt to establish interspecies communication. 297 00:32:00,400 --> 00:32:05,600 Is that weird or what? 298 00:32:05,600 --> 00:32:13,440 Our story begins in Italy where Carlo Cignasi runs a 24-acre vineyard in the Tuscan Hills. 299 00:32:13,440 --> 00:32:18,280 A music lover, Carlo was well known to serenade his great pickers with an accordion. 300 00:32:18,280 --> 00:32:36,840 In 2002, Carlo would stumble upon the true amazing power music could have when, as an 301 00:32:36,840 --> 00:32:43,880 ecologically friendly way of controlling pests from ruining his crop, Cignasi placed loudspeakers, 302 00:32:43,880 --> 00:32:50,200 all around his vineyard, to play 24-hour-a-day classical music. 303 00:32:50,200 --> 00:32:54,600 The pests were frightened away, but that's not all. 304 00:32:54,600 --> 00:32:57,200 Something else happened, something bizarre. 305 00:32:57,200 --> 00:33:03,600 The grapevines, nearest the speakers, grew 50% larger than the rest of the crop, matured 306 00:33:03,600 --> 00:33:09,480 more quickly and even grew towards the source of the music. 307 00:33:09,480 --> 00:33:13,880 It's fantastic to see how it's impossible to believe. 308 00:33:13,880 --> 00:33:16,760 The bunches are four times more. 309 00:33:16,760 --> 00:33:18,800 For example, they live two times more. 310 00:33:18,800 --> 00:33:22,520 So the sound is like a light. 311 00:33:22,520 --> 00:33:24,280 So why is this happening? 312 00:33:24,280 --> 00:33:32,800 Is there a logical explanation or is the reason far stranger? 313 00:33:32,800 --> 00:33:38,680 Could the soaring sounds of Bach and Mozart's delicate ditties revolutionize the way we 314 00:33:38,680 --> 00:33:41,320 treat our greenery? 315 00:33:41,320 --> 00:33:45,840 Researchers discovered that popular tracks such as Simon and Garfunkel's Ridgival Trouble 316 00:33:45,840 --> 00:33:53,080 Waters and Beethoven's Basterdoll Symphony improved milk yield in dairy cows by as much 317 00:33:53,080 --> 00:33:55,120 as one liter per day. 318 00:33:55,120 --> 00:33:57,120 Why? 319 00:33:57,120 --> 00:34:02,560 Because calming music was found to reduce stress in the animals. 320 00:34:02,560 --> 00:34:06,160 Happy moves equals more milk. 321 00:34:06,160 --> 00:34:08,840 Could something similar be happening with plants? 322 00:34:08,840 --> 00:34:17,720 Could relaxed grapes with impeccable musical taste ripen quicker? 323 00:34:17,720 --> 00:34:23,280 Could plants have an intelligence science has yet to fathom? 324 00:34:23,280 --> 00:34:28,520 Button is Dr. J. Deep Mathur says that the grapevines' response to music can be simply 325 00:34:28,520 --> 00:34:29,520 explained. 326 00:34:30,520 --> 00:34:33,440 Basically, we are talking about vibrations. 327 00:34:33,440 --> 00:34:40,560 Plants are able to exhibit primary perception where they can pick up happenings from their 328 00:34:40,560 --> 00:34:46,480 surroundings and that can be read out as electrical impulses. 329 00:34:46,480 --> 00:34:54,720 As far as classical music is concerned, perhaps there are certain tones, certain timbre, certain 330 00:34:54,720 --> 00:35:02,080 levels of vibration that plants are more responsive to in that particular music. 331 00:35:02,080 --> 00:35:07,000 Sound waves are vibrations in the air made up of different frequencies. 332 00:35:07,000 --> 00:35:11,320 The vibrations caused by the sound of music can be felt by the plants in their leaves 333 00:35:11,320 --> 00:35:14,640 or in the soil. 334 00:35:14,640 --> 00:35:19,280 Research suggests that plants may respond to music by increasing the expression of the 335 00:35:19,280 --> 00:35:24,400 genes, stimulating growth. 336 00:35:24,400 --> 00:35:28,080 So do plants just feel music rather than hearing it? 337 00:35:28,080 --> 00:35:36,440 Is the perceived wrath of grapes or joy just a boring biological response based on sound 338 00:35:36,440 --> 00:35:38,440 vibrations? 339 00:35:38,440 --> 00:35:41,440 Maybe. 340 00:35:41,440 --> 00:35:47,160 But Susan Dudley, a plant evolutionary ecologist, has another theory for why Carlos' grapevines 341 00:35:47,160 --> 00:35:49,440 grow so dramatically. 342 00:35:49,440 --> 00:35:53,960 That may have something to do with how the plants in the vineyards are related to each 343 00:35:53,960 --> 00:35:56,160 other. 344 00:35:56,160 --> 00:35:58,000 Every plant has a mother and a father. 345 00:35:58,000 --> 00:36:02,880 The vineyard in Tuscany could be doing better because they're planted next to their siblings. 346 00:36:02,880 --> 00:36:07,440 For some plants, we know the plants do do better when they're planted next to their siblings. 347 00:36:07,440 --> 00:36:11,720 And what my research does is show a possible mechanism for that, that they're not producing 348 00:36:11,720 --> 00:36:15,000 these competitive behaviors when they're with their siblings. 349 00:36:15,000 --> 00:36:18,280 So that's a plausible theory. 350 00:36:18,360 --> 00:36:23,600 To create a consistent grape, most vineyards use cuttings from healthy plants, then graft 351 00:36:23,600 --> 00:36:26,120 them onto rootstock. 352 00:36:26,120 --> 00:36:33,480 This means that often, most of the vines in a given field are genetically related clones. 353 00:36:33,480 --> 00:36:38,360 I went looking to see whether plants could recognize who their relatives were and behave 354 00:36:38,360 --> 00:36:40,480 differently with those relatives. 355 00:36:40,480 --> 00:36:46,400 What we found is that plants respond differently to liquid in which other seedlings had been 356 00:36:46,400 --> 00:36:47,400 it. 357 00:36:47,400 --> 00:36:51,040 You put the seedling in the liquid, you take it out, you put your test seedling in and 358 00:36:51,040 --> 00:36:52,040 you measure it. 359 00:36:52,040 --> 00:36:57,440 And it will grow more roots if that first seedling was a stranger. 360 00:36:57,440 --> 00:37:01,080 But it won't grow more roots if that first seedling was a sibling. 361 00:37:01,080 --> 00:37:04,840 And we had a control where we just lifted them out, put them back in again. 362 00:37:04,840 --> 00:37:09,720 So we definitely see that there's something soluble, some kind of chemical maybe that 363 00:37:09,720 --> 00:37:13,120 the roots probably put into the liquid that they're responding to. 364 00:37:13,120 --> 00:37:14,840 But we don't know what it is. 365 00:37:14,840 --> 00:37:19,720 Plants compete for limited resources like sunlight, nutrients and water, meaning there 366 00:37:19,720 --> 00:37:22,920 are winners and losers in this equation. 367 00:37:22,920 --> 00:37:29,120 Dudley's research has shown that when certain plants grow beside their kin, they work together 368 00:37:29,120 --> 00:37:34,880 for mutual survival and are more likely to all do well. 369 00:37:34,880 --> 00:37:40,400 With a winery, usually, vintners are planting all the same kind. 370 00:37:40,400 --> 00:37:43,080 They're not planting very different kinds together. 371 00:37:43,080 --> 00:37:47,760 So rather than better sharing because they're different, they might be sharing better because 372 00:37:47,760 --> 00:37:50,840 they're less competitive with each other. 373 00:37:50,840 --> 00:37:52,960 Okay, okay. 374 00:37:52,960 --> 00:37:56,280 And maybe I am barking up the wrong tree. 375 00:37:56,280 --> 00:37:57,280 Sorry. 376 00:37:57,280 --> 00:37:58,280 Seriously. 377 00:37:58,280 --> 00:38:06,960 What if the grapes of tuskiny and plants in general don't ripened or respond or grow 378 00:38:06,960 --> 00:38:10,080 tall and healthy because they love music? 379 00:38:10,080 --> 00:38:16,240 What if it's because they love each other? 380 00:38:16,240 --> 00:38:22,840 But can this sibling explanation sufficiently solve the mystery in the Italian vineyard? 381 00:38:22,840 --> 00:38:28,520 Family ties may make the vines grow better, but why would only some vines grow toward 382 00:38:28,520 --> 00:38:32,160 the speakers? 383 00:38:32,160 --> 00:38:36,320 Could the answer be far stranger than anything even science fiction writers might imagine? 384 00:38:40,840 --> 00:38:50,120 Could, as many researchers believe, vines and other plants be sentient beings capable 385 00:38:50,120 --> 00:38:56,120 of displaying conscious choice? 386 00:38:56,120 --> 00:39:04,720 I believe plants can sense now whether they can sense precisely our thoughts or the thoughts 387 00:39:04,720 --> 00:39:09,320 of other animals around them really remains to be proven. 388 00:39:09,320 --> 00:39:14,320 So I wouldn't go so far as saying that here they have the ESP and everything. 389 00:39:14,320 --> 00:39:22,680 However, what I definitely can say is they would be influenced very easily by their changes 390 00:39:22,680 --> 00:39:24,440 in their environment. 391 00:39:24,440 --> 00:39:31,560 And that maybe reflects to a certain extent the thought process we do not know. 392 00:39:31,560 --> 00:39:35,880 Jay Deep and his assistant Zach are going to put the sentient being theory to the test. 393 00:39:35,920 --> 00:39:40,680 They're going to hook up this plant to a state-of-the-art polygraph. 394 00:39:40,680 --> 00:39:44,440 Sensors will read the subtle changes in the plant's electrical activity to see how it 395 00:39:44,440 --> 00:39:47,240 responds to various stimuli. 396 00:39:47,240 --> 00:39:51,360 If there's a noticeable spike in the plant's electrical activity, then that would suggest 397 00:39:51,360 --> 00:39:55,800 that the plant can read human thoughts. 398 00:39:55,800 --> 00:40:01,320 I'm absolutely curious about what is the outcome from this particular experiment because it 399 00:40:01,320 --> 00:40:09,160 might actually be an opening for the way my own research direction will move into. 400 00:40:09,160 --> 00:40:14,360 Because if there's a positive response, I would really love to follow that up in a more 401 00:40:14,360 --> 00:40:18,720 scientific manner. 402 00:40:18,720 --> 00:40:22,000 For their first experiment, they're going to test what many gardeners believe to be 403 00:40:22,000 --> 00:40:29,800 a fact that plants respond well to human touch. 404 00:40:29,800 --> 00:40:34,160 Really brushing the leaves and the stems of the plant. 405 00:40:34,160 --> 00:40:36,680 No, sorry Zach. 406 00:40:36,680 --> 00:40:38,160 But there's no response. 407 00:40:38,160 --> 00:40:43,560 Now they're going to attempt what few scientists have ever tried before. 408 00:40:43,560 --> 00:40:44,560 Threatening thoughts. 409 00:40:44,560 --> 00:40:51,760 They're going to see if plants have ESP. 410 00:40:51,760 --> 00:40:55,040 No response so far. 411 00:40:56,040 --> 00:41:00,760 That's all I got. 412 00:41:00,760 --> 00:41:04,720 We haven't gotten any responses yet, eh? 413 00:41:04,720 --> 00:41:10,280 Since there's no response, J.G. and Zach are going to raise the intensity of the next experiment. 414 00:41:10,280 --> 00:41:13,960 They're going to threaten the plant with violence. 415 00:41:13,960 --> 00:41:21,600 Cut the plant. 416 00:41:21,600 --> 00:41:24,760 Hold on. 417 00:41:24,760 --> 00:41:31,640 So as soon as you were on the way to cut it, there's a huge spike. 418 00:41:31,640 --> 00:41:39,480 That's really interesting because it was at a lower level, spiked up, came down, went 419 00:41:39,480 --> 00:41:44,080 up again and then has now started resting at another level. 420 00:41:44,080 --> 00:41:47,600 So the spike actually comes prior to your action. 421 00:41:47,600 --> 00:41:52,280 Amazingly, before you could cut the plant, there's a noticeable spike on the line detector 422 00:41:52,280 --> 00:41:55,400 indicating a physiological response by the plant. 423 00:41:55,400 --> 00:42:01,120 That would suggest that the plant could read Zach's mind. 424 00:42:01,120 --> 00:42:07,680 This was almost the perfect moment for a plant to have become anxious when you reached it 425 00:42:07,680 --> 00:42:13,280 with a scissors with a very clear intention, at least in your mind, unspoken. 426 00:42:13,280 --> 00:42:19,240 So again, maybe we are looking at something real. 427 00:42:19,240 --> 00:42:24,320 Simply speaking, this hardly would count as a result unless we could repeat it multiple 428 00:42:24,320 --> 00:42:25,320 times. 429 00:42:25,320 --> 00:42:32,880 But the fact is, and it comes as a major surprise to me because I was not expecting this at 430 00:42:32,880 --> 00:42:34,380 all. 431 00:42:34,380 --> 00:42:38,400 And we had already gone through one plant and looked at the other one and gone through 432 00:42:38,400 --> 00:42:42,720 different situations where we realized this is not happening. 433 00:42:42,720 --> 00:42:48,480 And then suddenly, when Zach moves in with a scissor, and I guess with a very clear intention 434 00:42:48,480 --> 00:42:55,400 of carrying the thread out, there is a very, very clear spike. 435 00:42:55,400 --> 00:43:01,960 So if human beings are ever going to prove plants are sentient or have ESP, more research 436 00:43:01,960 --> 00:43:03,520 needs to be done. 437 00:43:03,520 --> 00:43:07,040 If it's ever proven true, the implications would be enormous. 438 00:43:07,040 --> 00:43:12,320 It would shake the very foundations of our human existence and necessitate a dramatic 439 00:43:12,320 --> 00:43:16,800 change in the way we relate with this mysterious species. 440 00:43:16,800 --> 00:43:22,000 Is it weird or what? 441 00:43:22,000 --> 00:43:25,200 So three weird mysteries. 442 00:43:25,200 --> 00:43:30,840 The multitude of even weirder possible explanations. 443 00:43:30,840 --> 00:43:35,480 A woman materializes from nowhere into an LA bathroom. 444 00:43:35,480 --> 00:43:39,920 Did she use a wormhole to travel through time? 445 00:43:39,920 --> 00:43:43,200 Did she travel faster than light speed? 446 00:43:43,200 --> 00:43:46,760 Is any of this possible? 447 00:43:46,760 --> 00:43:51,840 A mysterious stone structure in New England, proof that the ancient Celts settled the United 448 00:43:51,840 --> 00:43:55,240 States? 449 00:43:55,240 --> 00:43:58,000 Was this built by Native Americans? 450 00:43:58,000 --> 00:44:03,760 Or was it created in more recent times as a booze making factory? 451 00:44:03,760 --> 00:44:08,640 Vines in Italy seemingly respond to the sounds of Mozart. 452 00:44:08,640 --> 00:44:13,400 Are plants sentient beings with human feelings and desires? 453 00:44:13,400 --> 00:44:16,160 You decide. 454 00:44:16,160 --> 00:44:24,400 Show me next time for more stories that will undoubtedly be weird or what.
