1 00:00:00,000 --> 00:00:09,280 H. G. Wells had the time machine. Sherman and Mr. Peabody had the way back machine. And Michael J. 2 00:00:09,280 --> 00:00:15,440 Fox had a DeLorean. The fantasy of time travel is one of the most popular themes in science fiction. 3 00:00:15,440 --> 00:00:22,480 And now a tantalizing new theory suggests that time travel could someday be science fact. 4 00:00:22,480 --> 00:00:28,640 When time travel becomes possible, it will not be the kind of vehicle that's important, 5 00:00:28,800 --> 00:00:33,920 but rather the discovery of an interdimensional shortcut. In these scenes from Star Trek, 6 00:00:33,920 --> 00:00:39,040 the shortcut is a cosmic anomaly called a wormhole. We might have just discovered the 7 00:00:39,040 --> 00:00:44,960 first stable wormhole known to exist. Bring us about, Lieutenant. In science fiction, 8 00:00:44,960 --> 00:00:51,920 time travel is possible because cosmic anomalies not only warp space, they also warp time. But does 9 00:00:51,920 --> 00:00:57,440 science support the existence of these interstellar superhighways? The average scientist says that 10 00:00:57,520 --> 00:01:03,840 the distances between stars is so great, four light years to the nearest star, that star travel 11 00:01:03,840 --> 00:01:08,640 is simply impractical. It would take them hundreds of years to go between nearby star systems. 12 00:01:08,640 --> 00:01:13,120 Therefore, they are skeptical that we have been visited by aliens from out of space. 13 00:01:13,120 --> 00:01:17,920 Michio Kaku is a professor of theoretical physics at the City University of New York. 14 00:01:18,480 --> 00:01:24,560 In his book, Hyperspace, Kaku suggests that there is a mechanism capable of warping time. 15 00:01:24,640 --> 00:01:29,600 And Kaku does not rule out the possibility that another, more advanced civilization 16 00:01:29,600 --> 00:01:34,560 may have already found that mechanism, the unified field that Einstein dreamt about. 17 00:01:35,360 --> 00:01:39,920 The new wrinkle, which has caused quite a bit of excitement among theoretical physicists, 18 00:01:39,920 --> 00:01:47,360 is that perhaps this river of time can have eddy currents, whirlpools, and perhaps may even fork 19 00:01:47,920 --> 00:01:53,920 at a crucial juncture in history. But where those forks and eddies are, no one knows. 20 00:01:53,920 --> 00:02:00,240 The cosmic highway isn't marked with signs saying wormhole next right, or this way to ancient Egypt. 21 00:02:00,240 --> 00:02:05,200 At this point, just finding holes in space is more of a stumbling block than traveling through them. 22 00:02:05,920 --> 00:02:11,920 Perhaps an outer space extraterrestrials may have the capability with the technology thousands 23 00:02:11,920 --> 00:02:17,520 of years beyond our own to open a hole in space and to begin to manipulate the fabric of space and time. 24 00:02:18,160 --> 00:02:25,120 And that is precisely how Mark Davenport explains his belief that many UFO sightings are, in fact, 25 00:02:25,120 --> 00:02:31,920 extraterrestrial spacecraft. In Visitors From Time, Davenport describes hundreds of reported 26 00:02:31,920 --> 00:02:37,760 UFO sightings and alien abduction cases that he believes support his time travel theories. 27 00:02:38,720 --> 00:02:46,560 So my hypothesis is that these people who operate these ships, their technology is so 28 00:02:47,200 --> 00:02:52,720 advanced that they've actually figured out a way to artificially warp space time, the way a black hole 29 00:02:52,720 --> 00:02:58,160 does naturally. And if that's true, it could mean they could be coming here not only from other 30 00:02:58,160 --> 00:03:02,800 planets, but from other star systems, other galaxies, other dimensions that coexist with 31 00:03:02,800 --> 00:03:09,600 ours, parallel universes, even our own future or our own past. By collating and cross-referencing 32 00:03:09,600 --> 00:03:15,520 specifics from eyewitnesses, Davenport believes he has compelling evidence that many UFOs are 33 00:03:15,520 --> 00:03:21,680 actually time machines. We have the occupants of these craft are continually telling people, 34 00:03:22,560 --> 00:03:27,440 they ask them questions like what time is it, what is time, what is your time, what is age, 35 00:03:27,440 --> 00:03:33,840 what is a year, and they say you are caught in time and we're not, our time is different from yours. 36 00:03:34,640 --> 00:03:40,480 Time is distorted in the vicinity of these craft and inside these craft. A lot of times people's 37 00:03:40,480 --> 00:03:46,640 watches will stop. We have people who say that their voices are distorted when they're near 38 00:03:46,640 --> 00:03:52,800 this craft, like when they breathe helium or something. So we have all sorts of indication 39 00:03:52,800 --> 00:03:58,880 that these things are in some kind of a field that warps space and time. And one day, according to 40 00:03:58,880 --> 00:04:05,360 Mijiyo Kaku, science will catch up with science fiction and we will create a time machine of our 41 00:04:05,760 --> 00:04:10,560 most of my friends watch science fiction because they want to dream about what may be possible in 42 00:04:10,560 --> 00:04:16,000 the future. Real scientists at the cutting edge, working on the unified field theory, working on 43 00:04:16,000 --> 00:04:20,640 higher dimensions, working on time travel, these are the ones who are playful. These are the ones 44 00:04:20,640 --> 00:04:32,320 who let their imagination soar into hyperspace. Not all scientists agree with Mijiyo Kaku's hyperspace 45 00:04:32,320 --> 00:04:37,760 theory. Eminent physicist Stephen Hawking has stated that time travel is impossible because 46 00:04:37,760 --> 00:04:43,760 we've never been visited by any tourists from the future. Or have we?
