1 00:00:00,160 --> 00:00:03,240 Speaker 1: Well, this will knock your socks off. Literally. What if 2 00:00:03,279 --> 00:00:05,720 Speaker 1: I told you there was an explosion in nineteen oh 3 00:00:05,720 --> 00:00:08,840 Speaker 1: eight that was over two hundred and fifty times more 4 00:00:08,920 --> 00:00:12,959 Speaker 1: powerful than the atomic bomb dropped on Hiroshima. But it 5 00:00:13,039 --> 00:00:16,960 Speaker 1: wasn't mad made. I'm Patty Steele. To this day, nobody 6 00:00:17,040 --> 00:00:21,200 Speaker 1: knows what caused the Tunguska event. That's next on the backstory. 7 00:00:25,280 --> 00:00:29,960 Speaker 1: The backstory is back. Okay. It's a beautiful, peaceful summer morning, 8 00:00:30,280 --> 00:00:33,960 Speaker 1: June thirtieth, nineteen oh eight. We're in the remote Tunguska 9 00:00:34,000 --> 00:00:37,639 Speaker 1: region of Siberia, where daytime tempts in the summer can 10 00:00:37,680 --> 00:00:41,640 Speaker 1: actually reach into the eighties. But suddenly the tranquility is 11 00:00:41,760 --> 00:00:45,800 Speaker 1: shattered by an event so powerful it flattens more than 12 00:00:45,840 --> 00:00:50,640 Speaker 1: two thousand square kilometers of forest, some eighty million trees. 13 00:00:51,840 --> 00:00:55,680 Speaker 1: But oddly, it doesn't leave a crater. This massive blast 14 00:00:55,880 --> 00:00:59,600 Speaker 1: was a Tunguska explosion, estimated to be around two hundred 15 00:00:59,640 --> 00:01:03,480 Speaker 1: and fifty times more powerful than the atomic bomb dropped 16 00:01:03,520 --> 00:01:07,480 Speaker 1: on Hiroshima, Japan during World War II. Can you imagine 17 00:01:07,520 --> 00:01:10,560 Speaker 1: the shock for the few eye witnesses. It was a 18 00:01:10,680 --> 00:01:14,680 Speaker 1: very remote area. They were mostly local tribal folks, as 19 00:01:14,720 --> 00:01:17,600 Speaker 1: well as Russian settlers looking for a life away from 20 00:01:17,640 --> 00:01:21,280 Speaker 1: the big cities. What did they see and hear? Well? 21 00:01:21,480 --> 00:01:25,200 Speaker 1: They describe a vivid blue light, almost as bright as 22 00:01:25,240 --> 00:01:29,679 Speaker 1: the sun, and then a massive fireball streaking across the sky. 23 00:01:30,440 --> 00:01:35,039 Speaker 1: Next came multiple deafening explosions, and then a pillar of 24 00:01:35,120 --> 00:01:38,839 Speaker 1: fire that turns the sky into a deep and frightening 25 00:01:39,000 --> 00:01:43,319 Speaker 1: fiery red. Finally, a shock wave moves across the land 26 00:01:43,680 --> 00:01:48,040 Speaker 1: that literally knocks people off their feet, shattering windows hundreds 27 00:01:48,040 --> 00:01:52,120 Speaker 1: of miles away and even knocking over a train. Eventually, 28 00:01:52,200 --> 00:01:55,720 Speaker 1: the pillar of fire was replaced by a billowing tower 29 00:01:55,760 --> 00:01:58,960 Speaker 1: of smoke that seemed to reach all the way into space. 30 00:01:59,440 --> 00:02:02,760 Speaker 1: And think about this. Reports from the time say those 31 00:02:02,800 --> 00:02:07,120 Speaker 1: blasts were deafeningly loud hundreds of miles away, and the 32 00:02:07,160 --> 00:02:10,200 Speaker 1: skies three thousand miles away in Europe where it was 33 00:02:10,240 --> 00:02:13,680 Speaker 1: still night, as well as all over Asia, were glowing. 34 00:02:14,200 --> 00:02:17,639 Speaker 1: There are even several photographs that were taken around midnight 35 00:02:17,720 --> 00:02:20,560 Speaker 1: in Scotland and Sweden that looked like they were shot 36 00:02:20,639 --> 00:02:24,520 Speaker 1: during the day. But what was it? A meteor, a comet, 37 00:02:24,919 --> 00:02:29,000 Speaker 1: maybe a ufo. It took scientists almost twenty years to 38 00:02:29,080 --> 00:02:35,560 Speaker 1: actually reach the remote explosion site in Siberia. In nineteen 39 00:02:35,639 --> 00:02:38,960 Speaker 1: twenty seven, a researcher visited the center of the blast, 40 00:02:39,480 --> 00:02:42,200 Speaker 1: and it was forty years after the blast that anybody 41 00:02:42,280 --> 00:02:44,880 Speaker 1: was able to interview the few eye witnesses that were 42 00:02:44,919 --> 00:02:49,000 Speaker 1: still left. What really blew scientists away was the story 43 00:02:49,080 --> 00:02:52,079 Speaker 1: these people told of the sky lighting up a few 44 00:02:52,200 --> 00:02:55,680 Speaker 1: nights before the big blast took place that actually goes 45 00:02:55,720 --> 00:02:59,919 Speaker 1: against everything we know about impact explosions caused by comets 46 00:03:00,160 --> 00:03:03,919 Speaker 1: or meteors. The leading theory is that an asteroid or 47 00:03:03,960 --> 00:03:07,760 Speaker 1: a comet exploded in the Earth's atmosphere, known as an 48 00:03:07,760 --> 00:03:11,600 Speaker 1: air burst, releasing energy equal to as much as fifteen 49 00:03:11,680 --> 00:03:16,360 Speaker 1: megatons of TNT. But again, there was no impact crater found, 50 00:03:16,480 --> 00:03:19,440 Speaker 1: so that's still just a theory. And the problem with 51 00:03:19,520 --> 00:03:23,240 Speaker 1: that theory is that early exploration of the site turned 52 00:03:23,320 --> 00:03:27,160 Speaker 1: up absolutely no debris linked to an asteroid. And there 53 00:03:27,160 --> 00:03:31,080 Speaker 1: are other theories too. Some scientists thought that natural gas 54 00:03:31,160 --> 00:03:33,800 Speaker 1: leaking from the Earth could have been ignited by a 55 00:03:33,840 --> 00:03:39,600 Speaker 1: meteor causing that huge explosion. That seemed speculative at best. Now, 56 00:03:39,640 --> 00:03:43,040 Speaker 1: when you go into the more kind of outlandish explanations, 57 00:03:43,360 --> 00:03:47,360 Speaker 1: there are some folks who think that an extraterrestrial spacecraft 58 00:03:47,440 --> 00:03:53,120 Speaker 1: crashed at Tunguska, causing the explosion, but sadly for UFO enthusiasts, 59 00:03:53,200 --> 00:03:59,320 Speaker 1: that is not backed by any scientific evidence. The small 60 00:03:59,360 --> 00:04:03,280 Speaker 1: amount of collected years after the fact was impossible to 61 00:04:03,360 --> 00:04:08,640 Speaker 1: test due to environmental contamination. And there's another fascinating theory 62 00:04:08,680 --> 00:04:11,480 Speaker 1: that goes against all the laws of nature. It's the 63 00:04:11,520 --> 00:04:15,560 Speaker 1: black hole hypothesis. Some think that a tiny black hole 64 00:04:16,000 --> 00:04:20,279 Speaker 1: passed through Earth's atmosphere, causing the explosion, but again no 65 00:04:20,400 --> 00:04:24,799 Speaker 1: concrete evidence. Most importantly, what did the people who witness 66 00:04:24,920 --> 00:04:29,200 Speaker 1: this thing imagine? The fear you'd feel, no explanation, and 67 00:04:29,360 --> 00:04:31,680 Speaker 1: almost no way to communicate with the rest of the 68 00:04:31,720 --> 00:04:34,440 Speaker 1: world about what you'd seen. A lot of them thought 69 00:04:34,480 --> 00:04:37,240 Speaker 1: it was a sign of the end for humanity, sort 70 00:04:37,279 --> 00:04:42,280 Speaker 1: of like what dinosaurs experienced millions of years earlier. Now, interestingly, 71 00:04:42,520 --> 00:04:46,240 Speaker 1: the Tunguska explosion had a lasting impact on the world. 72 00:04:46,520 --> 00:04:50,479 Speaker 1: It influenced policy on the monitoring of space objects and 73 00:04:50,600 --> 00:04:54,920 Speaker 1: actually began asteroid tracking programs. It also became a fixture 74 00:04:54,960 --> 00:04:59,800 Speaker 1: in pop culture, inspiring books, movies, TV shows like episodes 75 00:04:59,800 --> 00:05:02,800 Speaker 1: of of Doctor Who, in The X Files, and of 76 00:05:02,920 --> 00:05:07,640 Speaker 1: course countless conspiracy theories. So here's the question. Have we 77 00:05:07,720 --> 00:05:11,320 Speaker 1: figured it out yet? No way. Over a century later, 78 00:05:11,600 --> 00:05:15,080 Speaker 1: the Tunguska explosion, or event as they call it, is 79 00:05:15,120 --> 00:05:19,200 Speaker 1: one of the twentieth century's greatest unsolved mysteries. Was it 80 00:05:19,240 --> 00:05:23,479 Speaker 1: a natural, cosmic event or something else. It's just one 81 00:05:23,520 --> 00:05:26,440 Speaker 1: example that shows we're still at the dawn of our 82 00:05:26,560 --> 00:05:38,919 Speaker 1: understanding of our universe.
