1 00:00:02,000 --> 00:00:07,000 Downloaded from YTS.MX 2 00:00:08,000 --> 00:00:13,000 Official YIFY movies site: YTS.MX 3 00:01:10,070 --> 00:01:13,031 Mérida, on the Yucatán Peninsula, 4 00:01:13,115 --> 00:01:18,704 is ground zero of the biggest cataclysmthat ever occurred to our planet. 5 00:01:19,162 --> 00:01:22,416 A whole asteroid hit right here. 6 00:01:23,125 --> 00:01:27,379 This happened millions of yearsbefore human beings appeared, 7 00:01:27,462 --> 00:01:32,217 and yet this fireball ritualfeels like a reenactment. 8 00:01:33,135 --> 00:01:37,222 Certainly, the ancient Mayascould not have known. 9 00:01:42,394 --> 00:01:45,981 We do not knowwhat in the future is coming at us, 10 00:01:46,064 --> 00:01:47,983 eventually destroying us. 11 00:01:48,483 --> 00:01:52,154 But it will look like this fireballover Siberia, 12 00:01:52,237 --> 00:01:54,239 only much larger. 13 00:01:56,658 --> 00:01:59,411 What simple dashboard cameras recorded 14 00:01:59,494 --> 00:02:01,788 feels like science fiction. 15 00:02:32,694 --> 00:02:34,905 Visitors from other worlds, 16 00:02:34,988 --> 00:02:38,408 from the dark of the universe, have come. 17 00:02:38,492 --> 00:02:41,370 And untold numbers are still on their way. 18 00:02:46,917 --> 00:02:49,461 If something big is going to happen, 19 00:02:49,545 --> 00:02:53,215 it will illuminate the skyeven in daylight. 20 00:02:53,757 --> 00:02:56,844 But that may be millions of years away. 21 00:03:00,806 --> 00:03:04,309 Meteorites have hit our planetall the time, 22 00:03:04,393 --> 00:03:08,063 and the bigger oneshave changed entire landscapes. 23 00:03:08,939 --> 00:03:12,734 But they also have lefta deep impact on cultures. 24 00:03:14,069 --> 00:03:16,655 A good example is Islamic culture. 25 00:03:17,155 --> 00:03:19,491 According to ancient tradition, 26 00:03:19,575 --> 00:03:23,120 a stone was sent down by Godfrom heaven 27 00:03:23,203 --> 00:03:27,374 as a guide for Adam and Evewhere to build an altar. 28 00:03:29,209 --> 00:03:31,128 The meteorite came down 29 00:03:31,211 --> 00:03:34,590 where later the holy city of Meccawas built. 30 00:03:41,680 --> 00:03:45,559 We are here at the holiest siteof the Muslim world. 31 00:03:46,185 --> 00:03:48,187 In its center, the Kaaba. 32 00:03:48,687 --> 00:03:52,065 Embedded in its eastern corner,the Black Stone. 33 00:03:52,649 --> 00:03:56,278 It was already veneratedin pre-Islamic times 34 00:03:56,361 --> 00:04:01,825 for at least a millennium beforethe prophet Muhammad founded Islam. 35 00:04:04,369 --> 00:04:08,207 The Black Stoneis framed entirely in silver, 36 00:04:08,290 --> 00:04:11,251 and nobody is allowed to analyze it, 37 00:04:11,335 --> 00:04:14,463 but it is almost certainly a meteorite. 38 00:04:18,759 --> 00:04:23,013 Islam is a religionof 1.9 billion faithful. 39 00:04:23,096 --> 00:04:24,681 For the pilgrims, 40 00:04:24,765 --> 00:04:28,602 the Black Stoneis among the most revered of relics. 41 00:04:29,102 --> 00:04:33,774 It attracts uncountable millionsof touches and kisses. 42 00:04:35,692 --> 00:04:41,114 As non-Muslims, we are not allowedeven to set foot into the holy city, 43 00:04:41,823 --> 00:04:46,870 and so we had to rely oncell phone footage of one of the faithful. 44 00:05:13,689 --> 00:05:18,277 Back in the silent vastnessof the Australian desert. 45 00:05:21,238 --> 00:05:24,533 Clive Oppenheimerof Cambridge University, 46 00:05:24,616 --> 00:05:29,121 who started our voyage of this film,explains to me... 47 00:05:30,622 --> 00:05:35,294 Scientists only became aware ofthis huge hole in the ground in 1947, 48 00:05:35,377 --> 00:05:37,379 when it was spotted from the air. 49 00:05:37,921 --> 00:05:41,758 And the crateris about a kilometer across. 50 00:05:41,842 --> 00:05:46,388 And it was formedwhen a piece of iron asteroid, 51 00:05:47,097 --> 00:05:51,518 the size of a battleshipand traveling at 15 kilometers per second, 52 00:05:51,602 --> 00:05:53,812 plummeted into the ground. 53 00:05:54,313 --> 00:05:58,275 And the crater wallsaround the floor here 54 00:05:58,358 --> 00:06:00,194 are made of the ancient rocks 55 00:06:00,277 --> 00:06:03,447 that were shattered by the impactand thrown about. 56 00:06:04,281 --> 00:06:10,329 The meteoroid itselfwas almost completely vaporized, 57 00:06:10,871 --> 00:06:12,998 and only a few fragments of it 58 00:06:13,081 --> 00:06:17,169 have been foundscattered across the surrounding desert. 59 00:06:19,755 --> 00:06:21,840 The pattern of ejecta 60 00:06:21,924 --> 00:06:26,094 suggests that the bolidecame from that direction over there. 61 00:06:26,929 --> 00:06:29,223 The temperatures are so phenomenal 62 00:06:29,306 --> 00:06:32,059 that it generates a huge thermal plume 63 00:06:32,142 --> 00:06:34,937 that punches up through the atmosphere,into the stratosphere, 64 00:06:35,020 --> 00:06:40,025 and it's raining out molten debrisover a very wide area. 65 00:06:40,108 --> 00:06:43,278 And, of course,there's colossal seismic energy 66 00:06:43,820 --> 00:06:46,448 that is generated by the impact itself, 67 00:06:46,532 --> 00:06:47,699 so huge earthquakes. 68 00:06:47,783 --> 00:06:50,452 I mean,we're in the middle of the desert here, 69 00:06:50,536 --> 00:06:56,750 but if you imagine this scenario happeningtoday in an urban environment, 70 00:06:56,834 --> 00:06:59,086 this would be absolutely devastating. 71 00:06:59,169 --> 00:07:02,881 To be hit by a meteoritehas barely ever happened? 72 00:07:02,965 --> 00:07:08,387 There was a womanwho was struck by a meteorite 73 00:07:08,470 --> 00:07:11,348 that came through her roof,through her ceiling, 74 00:07:11,431 --> 00:07:15,269 and hit her while she was seatedin an armchair watching TV. 75 00:07:15,352 --> 00:07:18,021 The Sylacauga meteorite. 76 00:07:18,897 --> 00:07:21,441 She survived itbut had a pretty horrific bruise. 77 00:07:27,990 --> 00:07:32,411 As bleak and uninviting asthe country around the crater looks, 78 00:07:32,494 --> 00:07:35,956 there were always aboriginal peoplein this area. 79 00:07:37,165 --> 00:07:40,085 Many of them make a living as artists. 80 00:07:40,169 --> 00:07:43,881 Like those in the nearest communityof Billiluna. 81 00:07:45,174 --> 00:07:49,887 They could not have witnessed the impactmore than 100,000 years ago, 82 00:07:49,970 --> 00:07:52,139 but there were more recent events 83 00:07:52,222 --> 00:07:54,850 that could have triggereda cultural memory. 84 00:07:55,559 --> 00:08:00,314 In their paintings,the crater frequently appears as a motif, 85 00:08:00,397 --> 00:08:02,482 but it goes deeper than that. 86 00:08:04,776 --> 00:08:06,653 We met Katie Darkie, 87 00:08:06,737 --> 00:08:09,781 one of the finest artistsof the community. 88 00:08:09,865 --> 00:08:12,242 This is one ofyour very own paintings, isn't it? 89 00:08:12,326 --> 00:08:13,744 Let's have a look at this one. 90 00:08:17,456 --> 00:08:19,875 Now please tell uswhat we're looking at here. 91 00:08:19,958 --> 00:08:21,126 It's a beautiful painting. 92 00:08:21,210 --> 00:08:22,586 This is the sand hill... 93 00:08:23,754 --> 00:08:25,506 and this is the grass. 94 00:08:25,589 --> 00:08:28,592 And it hasn't got any karnti.No potatoes. 95 00:08:29,259 --> 00:08:32,429 Long time ago, the old people said... 96 00:08:34,847 --> 00:08:38,769 one man went huntingthrough the creeks, hunting for birds. 97 00:08:38,852 --> 00:08:43,857 But he was walking throughthe tunnel underneath the river, 98 00:08:44,608 --> 00:08:46,151 but we call it a creek. 99 00:08:46,235 --> 00:08:48,946 And it came outon the other side of the crater 100 00:08:49,446 --> 00:08:54,618 and then went walking backto where he came from 101 00:08:55,244 --> 00:08:56,495 when he was hunting. 102 00:08:57,955 --> 00:09:01,917 And in this story, the crater,how was it formed? 103 00:09:02,000 --> 00:09:03,168 What's the origin? 104 00:09:03,794 --> 00:09:07,381 Well, in the kartiya world,there's a meteorite fell in there. 105 00:09:07,464 --> 00:09:10,926 -That's our story, the whitefellas' story.-The whitefella stories. 106 00:09:11,009 --> 00:09:13,929 Some say it's a star fell in there. 107 00:09:15,222 --> 00:09:17,891 But the ancestorsand the old people were telling us 108 00:09:18,642 --> 00:09:21,353 it's the Rainbow Serpentwho fell in the crater. 109 00:09:22,062 --> 00:09:25,774 So that's how we gotthree different stories about the crater. 110 00:09:25,858 --> 00:09:27,359 But it connects in one. 111 00:09:28,902 --> 00:09:30,487 We always take the kids. 112 00:09:31,405 --> 00:09:34,116 Every weekend we come and camp out there. 113 00:09:34,199 --> 00:09:39,830 And that's where we feel the presenceof our ancestors and our family, 114 00:09:40,330 --> 00:09:44,710 that they are looking after uswhen we go down and visit the crater. 115 00:09:45,961 --> 00:09:47,963 It's a very special place for us. 116 00:09:48,463 --> 00:09:51,216 For our families as well. 117 00:10:30,047 --> 00:10:32,883 Meteorites have fallen at random. 118 00:10:32,966 --> 00:10:36,845 A significant onein the Alsace region of France. 119 00:10:39,014 --> 00:10:44,394 But right here it changed human affairs.It influenced history. 120 00:11:09,086 --> 00:11:12,130 In the distance, the town of Ensisheim. 121 00:11:13,799 --> 00:11:17,636 In the 15th century,world history was shaped here, 122 00:11:17,719 --> 00:11:21,431 because the Hapsburg Empireearned legitimacy 123 00:11:21,515 --> 00:11:23,767 through a falling piece of rock. 124 00:11:24,935 --> 00:11:27,771 A plaque marks a spot where it fell. 125 00:11:31,817 --> 00:11:34,778 Clive brought Professor Simon Schaffer, 126 00:11:34,862 --> 00:11:37,531 a colleague from Cambridge University. 127 00:11:38,448 --> 00:11:43,662 He is a historian of scienceand one of the few remaining polymaths. 128 00:11:44,621 --> 00:11:49,376 What happened on that day in--7th of November, 1492? 129 00:11:49,960 --> 00:11:53,839 So, on this extraordinary day, 130 00:11:53,922 --> 00:11:58,468 a fireball appearedin the southeast sky in that direction, 131 00:11:58,552 --> 00:12:03,223 moving incredibly fastand whistling as it came. 132 00:12:03,307 --> 00:12:08,729 And then it hit this fieldat about 11:30 in the morning. 133 00:12:09,188 --> 00:12:11,940 There was, according to most reports, 134 00:12:12,024 --> 00:12:14,651 just one person standing in the field. 135 00:12:14,735 --> 00:12:16,069 A shepherd boy. 136 00:12:16,153 --> 00:12:18,488 And he would have seenthe most extraordinary thing. 137 00:12:18,572 --> 00:12:24,244 He would have seen a 300-pound rockhit the field 138 00:12:24,328 --> 00:12:26,872 and gouge out a hole. 139 00:12:27,497 --> 00:12:30,792 The 7th of November, 1492, 140 00:12:30,876 --> 00:12:33,962 the moment when this stone fell, 141 00:12:34,046 --> 00:12:40,093 was only a few daysafter another great landfall: 142 00:12:40,177 --> 00:12:43,722 the arrival of Christopher Columbusand his crew 143 00:12:43,805 --> 00:12:47,017 in their New World,in the Caribbean. 144 00:12:48,101 --> 00:12:50,729 It's thanks to Columbus, ultimately, 145 00:12:50,812 --> 00:12:53,899 that there is corn growing in this field. 146 00:12:53,982 --> 00:12:59,279 This is the result of the eruptioninto European agriculture 147 00:12:59,363 --> 00:13:02,866 of crops that up till thenhad only grown in the Americas. 148 00:13:03,367 --> 00:13:07,287 Indeed, the fall of the stonewas so important 149 00:13:07,371 --> 00:13:11,834 that there are some chroniclescovering the year 1492 150 00:13:11,917 --> 00:13:14,920 that only mention the Ensisheim stone 151 00:13:15,003 --> 00:13:17,089 and simply leave Columbus out. 152 00:13:18,590 --> 00:13:23,595 It had fallen, perhaps by divine design,as they thought, 153 00:13:23,679 --> 00:13:27,641 very near an extremely significant town, 154 00:13:27,724 --> 00:13:30,102 Ensisheim in Alsace. 155 00:13:30,185 --> 00:13:32,104 Ensisheim at that point 156 00:13:32,187 --> 00:13:36,483 was the headquartersof the Austrian forces 157 00:13:36,567 --> 00:13:38,318 in this part of the world. 158 00:13:38,402 --> 00:13:42,489 And within two weeksof the arrival of the stone, 159 00:13:42,990 --> 00:13:46,076 the Austrian military commander, 160 00:13:46,159 --> 00:13:50,581 the commander in chief, Maximilian,also arrived in the town. 161 00:13:51,957 --> 00:13:56,295 But, for heaven's sake,why did this stone fall here at this time? 162 00:13:56,378 --> 00:14:02,885 The reason this stone fell in this fieldwas exactly for heaven's sake. 163 00:14:03,510 --> 00:14:04,887 For those people, 164 00:14:05,387 --> 00:14:09,349 wonderful supernatural signsin the heavens were messages. 165 00:14:09,433 --> 00:14:12,936 This was, as it were,an e-mail sent from God 166 00:14:13,020 --> 00:14:15,647 to the subjects of Maximilian 167 00:14:15,731 --> 00:14:18,066 to tell them that his rule was legitimate, 168 00:14:18,150 --> 00:14:19,943 that he would defeat his enemies, 169 00:14:20,027 --> 00:14:22,321 and that they should obey his commands. 170 00:14:22,404 --> 00:14:24,489 Where do you get your fascination from? 171 00:14:24,948 --> 00:14:29,828 I think one of the things that I findcompletely obsessional about meteorites 172 00:14:29,912 --> 00:14:35,042 is that they carry sense,that they carry meaning. 173 00:14:35,125 --> 00:14:40,005 They arrive, so it was thought,with other kinds of falls. 174 00:14:40,088 --> 00:14:45,802 With body partsand frogs and rains of blood. 175 00:14:45,886 --> 00:14:48,472 With plagues and other catastrophes. 176 00:14:48,555 --> 00:14:53,185 Something like a meteoriteis an organism, 177 00:14:53,268 --> 00:14:56,480 an animal, almost, that speaks to us. 178 00:14:56,563 --> 00:15:00,192 And I think that'sa very powerful and eloquent idea. 179 00:15:00,275 --> 00:15:06,281 The idea that... meteorites have meaning, 180 00:15:07,157 --> 00:15:11,995 and the task of humanityis to interpret what that meaning is. 181 00:15:13,038 --> 00:15:15,624 Simon Schaffer could have continued, 182 00:15:15,707 --> 00:15:20,045 without getting boring,nonstop for the next eight hours. 183 00:15:20,128 --> 00:15:25,050 But we wanted to see the remainsof the real stone in the local museum. 184 00:15:26,093 --> 00:15:29,680 It feels unreal, inviting fantasies. 185 00:15:31,682 --> 00:15:35,102 The mayor of town wanted to greet us, 186 00:15:35,185 --> 00:15:38,856 here flanked by friends of the meteorite. 187 00:15:40,065 --> 00:15:43,986 This emblem is takenfrom a medieval woodcut. 188 00:15:44,570 --> 00:15:46,321 You find it everywhere. 189 00:15:47,781 --> 00:15:53,537 But today it means thinking backand thinking ahead in centuries. 190 00:15:54,872 --> 00:15:58,417 Did these membersof the brotherhood of the stone 191 00:15:58,500 --> 00:16:01,420 have a far-off future in mind? 192 00:16:02,129 --> 00:16:03,964 What are they thinking? 193 00:16:04,548 --> 00:16:07,718 What far-reaching plans do they have? 194 00:16:09,678 --> 00:16:12,806 What if the human race became extinct? 195 00:16:14,016 --> 00:16:19,313 What would we leavefor future astronauts of an alien galaxy 196 00:16:19,396 --> 00:16:24,276 to demonstrate that we would not leavea fallen comrade behind? 197 00:16:25,861 --> 00:16:30,616 Right next to the stone,we discovered this installation. 198 00:16:36,330 --> 00:16:38,248 "Hi, my name is Jean," 199 00:16:38,332 -->

372 00:27:58,387 --> 00:28:02,891 So, a quasicrystal is a form of matterthat we thought was impossible. 373 00:28:03,392 --> 00:28:07,145 For hundreds of years, we were convincedthat we had proven that it was impossible. 374 00:28:08,230 --> 00:28:12,067 But, as we now know today,not only is it possible, 375 00:28:12,150 --> 00:28:14,611 but it was made in the universe long ago, 376 00:28:14,695 --> 00:28:16,280 long before we ever imagined. 377 00:28:16,363 --> 00:28:17,990 But let's begin with something simple. 378 00:28:18,824 --> 00:28:21,660 Crystals follow a pattern of order, 379 00:28:21,743 --> 00:28:24,413 like the tiling of your bathroom floor. 380 00:28:24,496 --> 00:28:27,374 -Okay.-Just simple squares. 381 00:28:27,457 --> 00:28:30,169 Square tiles fit seamlessly. 382 00:28:30,252 --> 00:28:33,839 But with pentagons, a fivefold symmetry, 383 00:28:33,922 --> 00:28:35,465 you are quickly in trouble. 384 00:28:35,924 --> 00:28:38,177 Let's come out this way a little bit. 385 00:28:38,677 --> 00:28:40,095 And... 386 00:28:40,512 --> 00:28:42,264 I can already seewhere the problem's gonna come from. 387 00:28:42,347 --> 00:28:44,183 Yeah, you see what's happening? 388 00:28:44,266 --> 00:28:47,436 We've opened up a gap.So now we have some choices to make. 389 00:28:47,519 --> 00:28:49,313 We're not gonna be able to fill that in. 390 00:28:49,396 --> 00:28:51,023 I could either put it there or there, 391 00:28:51,106 --> 00:28:53,192 -but there's never gonna be a way to...-Yeah. 392 00:28:54,401 --> 00:28:55,986 Atoms hate having gaps, 393 00:28:56,069 --> 00:28:58,280 so the moment you produce gapswith real atoms, 394 00:28:58,363 --> 00:29:00,490 they're going to move aroundand get rid of them. 395 00:29:00,574 --> 00:29:04,077 Fivefold symmetry was famouslyforbidden for matter. 396 00:29:04,536 --> 00:29:09,208 But quasicrystals are evenmore complex and mysterious than this. 397 00:29:10,083 --> 00:29:13,545 Let's just take a lookat a quasicrystal pattern first 398 00:29:13,629 --> 00:29:16,298 to get a visual impressionof what they're like. 399 00:29:16,381 --> 00:29:20,677 So, a good example is this tilingthat you see on the table. 400 00:29:20,761 --> 00:29:25,098 If you study it, you'll see it's madeof only two pieces, those two shapes. 401 00:29:25,641 --> 00:29:26,808 They're chickens. 402 00:29:27,684 --> 00:29:30,145 This looks like a puzzle for children, 403 00:29:30,229 --> 00:29:33,315 but there is ingenious mathematicsbehind it. 404 00:29:34,316 --> 00:29:38,487 This pattern was discoveredby Sir Roger Penrose in the 1970s. 405 00:29:39,446 --> 00:29:43,367 A mathematician and sometimesa cosmologist as well. 406 00:29:44,201 --> 00:29:47,579 It is astonishingthat a quasicrystal pattern 407 00:29:47,663 --> 00:29:51,708 can be found in a shrinein Isfahan, in Iran. 408 00:29:52,167 --> 00:29:56,964 Without any knowledge ofthe underlying mathematical principles, 409 00:29:57,047 --> 00:30:00,092 artisans more than 500 years ago 410 00:30:00,175 --> 00:30:04,596 solved the impossible geometryof fivefold symmetry. 411 00:30:05,597 --> 00:30:06,807 There we go. 412 00:30:09,226 --> 00:30:10,352 Now, I should warn you... 413 00:30:10,435 --> 00:30:12,563 The warning was justified. 414 00:30:13,021 --> 00:30:16,733 Yes, indeed, it gets so complicated now 415 00:30:16,817 --> 00:30:20,279 that we are not going to torture youwith details. 416 00:30:20,737 --> 00:30:22,239 Just a sample. 417 00:30:22,948 --> 00:30:27,911 So, instead of just one icosahedron,we have an icosahedron of icosahedra. 418 00:30:28,495 --> 00:30:31,790 And we said, "Oh, maybe that's a wayof building something ever outwards 419 00:30:31,874 --> 00:30:33,375 that maintains this structure." 420 00:30:34,042 --> 00:30:35,252 But we ran into trouble. 421 00:30:35,961 --> 00:30:38,964 But this model here solved the problem. 422 00:30:39,047 --> 00:30:41,967 It represents a true quasicrystal. 423 00:30:42,050 --> 00:30:44,052 ...and you could only just buildthis plane... 424 00:30:44,136 --> 00:30:47,848 Now Steinhardtwanted to find one in nature. 425 00:30:50,225 --> 00:30:53,353 You ended up doing fieldwork in Kamchatka. 426 00:30:53,437 --> 00:30:55,606 That must've been inspiredthrough the theoretical-- 427 00:30:55,689 --> 00:30:57,524 Yeah. Inspired by this model. 428 00:30:57,608 --> 00:30:58,901 Because what this model says: 429 00:30:58,984 --> 00:31:02,779 "Well, actually, if the atoms have forcesthat are like these interlocks, 430 00:31:02,863 --> 00:31:05,324 they have no choicebut to form this structure." 431 00:31:05,407 --> 00:31:06,950 It immediately got me to thinking, 432 00:31:07,034 --> 00:31:11,413 "Is it possible that nature has madea quasicrystal before humans did?" 433 00:31:11,496 --> 00:31:16,627 And so that began a decades-long searchfor a natural quasicrystal. 434 00:31:17,169 --> 00:31:21,882 We eventually found a mineralogistin Florence named Luca Bindi 435 00:31:21,965 --> 00:31:25,802 who had in his museuma tiny little sample of-- 436 00:31:26,303 --> 00:31:28,889 well, a rock, a complex rock, 437 00:31:28,972 --> 00:31:32,226 which had inside ita little grain of quasicrystal. 438 00:31:32,976 --> 00:31:35,229 By studying that particular sample, 439 00:31:35,312 --> 00:31:39,274 we had some hints that what we hadin hand was a piece of a meteorite. 440 00:31:39,358 --> 00:31:44,655 But to prove the case, we had to find outwhere that rock really came from 441 00:31:44,738 --> 00:31:47,616 and see if we could gather moreof the sample to prove the case. 442 00:31:48,158 --> 00:31:51,203 So Paul Steinhardt and Luca Bindi 443 00:31:51,286 --> 00:31:54,915 set out on an expeditionto easternmost Russia, 444 00:31:54,998 --> 00:31:56,959 close to the Bering Strait. 445 00:31:59,878 --> 00:32:04,091 The red marker shows the siteof the meteorite fragments. 446 00:32:05,008 --> 00:32:09,763 They were found along a creeknamed Listvenitovyi, 447 00:32:10,180 --> 00:32:12,099 of which nobody has ever heard. 448 00:32:13,141 --> 00:32:18,438 The expedition included membersof the original Russian geological team 449 00:32:18,522 --> 00:32:22,317 that had found the first sampledecades ago. 450 00:32:36,874 --> 00:32:39,918 They had to negotiate uncharted terrain, 451 00:32:40,002 --> 00:32:42,921 totally novel for Paul Steinhardt, 452 00:32:43,005 --> 00:32:49,636 whose outdoor experience did not extendbeyond the lawns of Princeton University. 453 00:33:00,397 --> 00:33:03,817 Myriads of mosquitoes tormented him. 454 00:33:04,318 --> 00:33:07,696 Here we see him with a mosquito netover his face. 455 00:33:08,280 --> 00:33:10,365 His sleep was fitful. 456 00:33:10,782 --> 00:33:15,370 Bears not only appeared in his nightmares,they were really out there. 457 00:33:16,622 --> 00:33:20,584 Their hard work to find fragmentsof the meteorite paid off. 458 00:33:21,710 --> 00:33:25,172 First inspection of their findingslooked promising. 459 00:33:26,215 --> 00:33:30,344 Now Bindi and Steinhardthad reason to celebrate, 460 00:33:30,427 --> 00:33:35,307 although they could not yet knowif quasicrystals were present. 461 00:33:37,351 --> 00:33:41,647 The X-ray diffraction patternof the newly found samples 462 00:33:41,730 --> 00:33:44,900 revealed the forbidden fivefold symmetry, 463 00:33:44,983 --> 00:33:49,363 proof there were quasicrystalswithin the meteorite. 464 00:33:49,446 --> 00:33:52,199 Could you describeyour emotion when you saw this? 465 00:33:52,950 --> 00:33:56,662 I think everything-- time seemedto stop for me at that moment. 466 00:33:58,247 --> 00:33:59,248 As... 467 00:34:00,832 --> 00:34:04,336 Just seeing this imagejust told me immediately 468 00:34:04,419 --> 00:34:07,464 that everything we had beentrying to achieve for decades 469 00:34:07,548 --> 00:34:09,424 had now been achieved. 470 00:34:09,507 --> 00:34:13,762 Plus, we had verifiedthat this quasicrystal 471 00:34:13,846 --> 00:34:17,516 not only was formed in nature,but had been formed in space. 472 00:34:19,101 --> 00:34:22,312 Leaving the arcane mysteriesof matter behind, 473 00:34:22,771 --> 00:34:27,525 we turn toward some more average rocksthat had come down upon us. 474 00:34:27,609 --> 00:34:30,070 ...so we have some sticky mats here. 475 00:34:31,905 --> 00:34:36,534 Arizona State Universityhouses a large collection. 476 00:34:36,618 --> 00:34:39,663 The dirt that we have from outsidegoing into the clean vault. 477 00:34:39,746 --> 00:34:42,666 But wild stories were waiting for us. 478 00:34:42,748 --> 00:34:43,583 So when we go in, 479 00:34:43,667 --> 00:34:45,752 make sure you just step on thereto get the dirt off your feet. 480 00:34:45,835 --> 00:34:46,670 All right. 481 00:34:46,753 --> 00:34:49,464 Laurence Garvie,its curator, guided us. 482 00:34:49,547 --> 00:34:53,927 We have a positive pressure in here,just to keep sort of clean air coming in. 483 00:34:54,011 --> 00:34:55,637 -Got the dirt off?

We're all stardust. 649 00:44:23,872 --> 00:44:26,124 -Eventually.-A wonderful thought. 650 00:44:26,208 --> 00:44:27,042 Yeah. 651 00:44:27,125 --> 00:44:31,088 This was the only time throughoutthe entire shooting of this film 652 00:44:31,171 --> 00:44:33,423 where I could not resist. 653 00:44:33,507 --> 00:44:36,468 I had to intervene from behind the camera. 654 00:44:37,010 --> 00:44:40,222 I think I'm not stardust. I'm Bavarian. 655 00:44:44,685 --> 00:44:47,187 Yeah, that's made ofspecial stuff, that is. 656 00:44:47,813 --> 00:44:49,857 Yeah. That's right. 657 00:44:58,782 --> 00:45:00,367 Our voyage took us 658 00:45:00,450 --> 00:45:04,496 to wherever large fireballshad plunged down to Earth. 659 00:45:05,372 --> 00:45:09,293 We wanted to knowif life had come from outer space. 660 00:45:10,252 --> 00:45:16,425 This is Ramgarh Crater in Rajasthan,in Northern India, four kilometers across. 661 00:45:17,259 --> 00:45:20,262 From spaceit immediately catches the eye, 662 00:45:20,345 --> 00:45:24,850 but down on the groundyou barely notice you are inside a crater. 663 00:45:25,392 --> 00:45:30,230 However, Hindu temples were built heresince the 10th century. 664 00:45:32,482 --> 00:45:36,403 We were curiousif organic matter in meteorites 665 00:45:36,486 --> 00:45:41,033 could have provided the ingredientsof life on our planet. 666 00:45:42,367 --> 00:45:46,788 We were seeking the expertiseof Professor Nita Sahai, 667 00:45:46,872 --> 00:45:51,001 who studies the transitionfrom chemistry to biology. 668 00:45:52,127 --> 00:45:56,173 And we're in this--in this huge crater here, 669 00:45:56,256 --> 00:45:58,175 formed by a meteorite impact. 670 00:45:58,258 --> 00:46:00,802 And we don't knowwhether it was a carbonaceous one, 671 00:46:00,886 --> 00:46:03,722 but we know thatthese carbonaceous meteorites 672 00:46:03,805 --> 00:46:06,308 have all kindsof organic molecules in them. 673 00:46:06,391 --> 00:46:10,562 What are the key ones that might representbuilding blocks of life? 674 00:46:10,646 --> 00:46:14,441 Actually, all of the building blocksof life have been found in meteorites. 675 00:46:14,525 --> 00:46:17,069 Amino acids that make up proteins, 676 00:46:17,152 --> 00:46:20,072 lipid molecules that make upcell membranes 677 00:46:20,155 --> 00:46:23,075 and, amazingly, even ribose,which is a sugar. 678 00:46:23,158 --> 00:46:25,577 I just find it astonishing, you know, 679 00:46:25,661 --> 00:46:30,332 that you can find sugars and thingsthat make proteins in a meteorite. 680 00:46:30,415 --> 00:46:31,250 Right. 681 00:46:31,333 --> 00:46:35,170 Are they made geologically,like minerals, or... 682 00:46:35,754 --> 00:46:39,341 They're not like minerals, in the sensethat they're organic molecules 683 00:46:39,424 --> 00:46:40,759 and minerals are inorganic, 684 00:46:40,843 --> 00:46:42,970 but they have been formed presumably 685 00:46:43,053 --> 00:46:46,974 by the interactions of organic moleculeswith mineral surfaces. 686 00:46:47,057 --> 00:46:50,727 For example, on interstellar grains, 687 00:46:50,811 --> 00:46:53,772 as well as on the surfacesof the meteorites themselves. 688 00:46:54,356 --> 00:46:56,650 And, I mean, there's still a big step 689 00:46:56,733 --> 00:47:00,445 from having these ingredientsto sparking life. 690 00:47:00,529 --> 00:47:02,322 -Right.-What do we need? 691 00:47:02,406 --> 00:47:04,992 I guess we need some kind of crucibleto put this stuff in 692 00:47:05,075 --> 00:47:06,785 and a heat source? 693 00:47:06,869 --> 00:47:10,205 Yeah. So, you need to getthese simple building blocks 694 00:47:10,289 --> 00:47:12,541 polymerized into longer chains, 695 00:47:12,624 --> 00:47:17,546 because the longer chains have the abilityto fold and be functional. 696 00:47:17,629 --> 00:47:19,631 What do you think of the ideaof panspermia, 697 00:47:19,715 --> 00:47:23,302 that life is dispersedaround the universe? 698 00:47:23,385 --> 00:47:26,054 I mean, is it conceivablethat living organisms 699 00:47:26,138 --> 00:47:29,975 could survive the intense temperaturesand radiation of outer space? 700 00:47:30,517 --> 00:47:33,353 DNA has actually been foundto be quite robust. 701 00:47:33,437 --> 00:47:37,524 And it's possible to survive in space. 702 00:47:37,983 --> 00:47:42,696 And even an entire organism might survivein a spore-like mode. 703 00:47:42,779 --> 00:47:46,450 'Cause people have actuallydug deep into the Earth 704 00:47:46,533 --> 00:47:50,120 and even a couple of kilometers down 705 00:47:50,204 --> 00:47:54,791 they find bacteria that have been livingthere presumably for millions of years. 706 00:47:54,875 --> 00:47:59,505 And they survive in this state of,kind of, suspended animation. 707 00:47:59,588 --> 00:48:02,841 Do you have any idea why the priestsbuilt their temples here? 708 00:48:02,925 --> 00:48:05,302 I mean, and this one'sdedicated to Shiva, you know? 709 00:48:05,385 --> 00:48:09,765 I mean, it seems too good to be true,on the floor of a meteorite-impact crater. 710 00:48:09,848 --> 00:48:14,394 It's kind of interesting that this templeis dedicated to Shiva and Parvati. 711 00:48:14,478 --> 00:48:19,900 And it's a tantric temple,which represents creation. 712 00:48:19,983 --> 00:48:22,110 And Shiva is also the god of destruction. 713 00:48:22,569 --> 00:48:25,072 So, in Hindu mythology,there is this idea 714 00:48:25,155 --> 00:48:28,784 of cycles of creationand destruction of the universe. 715 00:48:28,867 --> 00:48:32,704 And, appropriately,it's in a meteor-impact crater site, 716 00:48:32,788 --> 00:48:36,124 where the impact can wipe out life, 717 00:48:36,208 --> 00:48:38,794 but then also deliverthese organic molecules 718 00:48:38,877 --> 00:48:41,129 that could have seeded lifein the first place. 719 00:48:45,592 --> 00:48:50,180 This was confirmed in a similar wayby a resident sadhu. 720 00:48:51,014 --> 00:48:56,645 If humanity and all life becomes extinctby war or a meteorite, 721 00:48:56,728 --> 00:49:01,108 life will regenerate at this place,at this crater lake. 722 00:49:10,450 --> 00:49:14,663 We had to go wherethe most colossal fireball came down. 723 00:49:15,622 --> 00:49:19,084 It was at a placewith an unpronounceable name, 724 00:49:19,168 --> 00:49:22,880 at the coastof the Yucatán Peninsula in Mexico. 725 00:49:24,882 --> 00:49:30,804 This is the very place where our planetsuffered an unimaginable apocalypse. 726 00:49:31,597 --> 00:49:34,850 What came down from space right here 727 00:49:34,933 --> 00:49:40,105 had the force of hundreds of millions--possibly thousands of millions-- 728 00:49:40,189 --> 00:49:43,066 of atomic bombs Hiroshima's size. 729 00:49:44,610 --> 00:49:47,571 Nothing out here is reminiscent of it. 730 00:49:48,113 --> 00:49:51,992 Only leaden boredomweighs upon everything. 731 00:49:54,203 --> 00:50:00,292 Chicxulub is a beach resortso godforsaken you want to cry. 732 00:51:12,489 --> 00:51:15,826 The dogs here,like all dogs on this planet, 733 00:51:15,909 --> 00:51:19,121 are just too dim-witted to understand 734 00:51:19,204 --> 00:51:22,708 that three-quarters of all specieswere extinguished 735 00:51:22,791 --> 00:51:25,627 by the event that took place right here. 736 00:51:31,550 --> 00:51:35,304 The dinosaurs have only survivedin a local museum. 737 00:51:38,265 --> 00:51:42,477 Their eyes were made by humans.They recognize nothing. 738 00:51:44,062 --> 00:51:46,690 Only their footprints are authentic, 739 00:51:46,773 --> 00:51:50,527 but they showthey were ambling along, not fleeing. 740 00:51:51,612 --> 00:51:54,781 They were obliviousto the sudden death of everything. 741 00:52:13,550 --> 00:52:15,928 This godforsaken spot is at the center 742 00:52:16,011 --> 00:52:19,681 of one of the greatest geologicalcataclysms in Earth history. 743 00:52:20,182 --> 00:52:24,436 It irreversibly changed the course of lifeon the planet. 744 00:52:24,520 --> 00:52:26,605 Some 66 million years ago, 745 00:52:26,688 --> 00:52:29,066 an asteroid, perhaps 10 kilometers across, 746 00:52:29,149 --> 00:52:34,029 came hurtling to the Earthat speeds of 20 kilometers a second. 747 00:52:34,905 --> 00:52:37,574 The force of the impactwas so phenomenal 748 00:52:37,658 --> 00:52:41,495 that it excavated a hole30 kilometers deep. 749 00:52:42,246 --> 00:52:44,373 The crater that formed... 750 00:52:44,456 --> 00:52:49,670 stretches out 100 kilometers out to seaand 100 kilometers inland, 751 00:52:50,212 --> 00:52:54,508 and the temperaturesgenerated in the crust from the impact 752 00:52:54,591 --> 00:52:59,805 melted and vaporized the crustand the bolide itself. 753 00:53:00,597 --> 00:53:03,308 There were earthquakes of magnitude 11. 754 00:53:03,392 --> 00:53:07,938 That's a hundred times greaterthan any historical earthquake. 755 00:53:08,021 --> 00:53:10,691 Mega-tsunami, 100-meter-high waves, 756 00:53:10,774 --> 00:53:14,152 ravaged the shorelines of distant oceans, 757 00:53:14,236 --> 00:53:19,658 and a vast pall of dustand molten droplets and gases 758 00:53:19,741 --> 00:53:21,285 soared into the atmosphere, 759 00:53:21,368 --> 00:53:25,998 some of the material even reachingescape velocity and exiting into space. 760 00:53:26,665 --> 00:53:31,044 Those molten droplets rained outover an area of 3,000 kilometers, 761 00:53:31,128 --> 00:53:34,214 igniting firestorms on the land. 762 00:53:34,298 --> 00:53:36,717 I love how movies depict it. 763 00:53:36,800 --> 00:53:40,012 800 kilometers from the impact site, 764 00:53:40,095 --> 00:53:41,805 the light is so intense 765 00:53:41,889 --> 00:53:45,142 it causes the flesh of the Alamosaurusto appear transparent... 766 00:53:47,811 --> 00:53:50,981 and burns images of their shadowsonto the ground. 767 00:53:54,568 --> 00:53:57,154 The scorching light sears their eyeballs. 768 00:53:57,237 --> 00:53:59,740 They now can't seewhat's headed their way. 769 00:54:00,741 --> 00:54:02,117 But they can feel it. 770 00:54:04,703 --> 00:54:06,622 Now, mammals, they made it through, 771 00:54:06,705 --> 00:54:10,125 and they took advantageof the new ecological opportunities. 772 00:54:11,376 --> 00:54:14,796 We probably wouldn't be here ourselves,Homo sapiens as a species, 773 00:54:14,880 --> 00:54:17,382 were it not for this colossal impact. 774 00:54:18,967 --> 00:54:23,889 Nobody knew there is an impact crateruntil the 1970s. 775 00:54:24,431 --> 00:54:30,896 Gravity anomalies and borehole datarevealed its structure and immense size. 776 00:54:31,563 --> 00:54:33,941 The only surface manifestation 777 00:54:34,024 --> 00:54:38,654 is an enigmatic ring of water holescalled cenotes. 778 00:54:39,363 --> 00:54:42,449 They are a geological echo of the impact. 779 00:54:43,617 --> 00:54:47,454 Since there are no rivers and lakesin the Yucatán Peninsula, 780 00:54:47,955 --> 00:54:51,208 these water holes attractedthe ancient Mayas. 781 00:54:52,543 --> 00:54:55,170 Without the presence of cenotes, 782 00:54:55,254 --> 00:54:59,842 this cultural center of Chichén Itzáwould never have been built. 783 00:55:02,010 --> 00:55:05,639 They developed a high culturewith a writing system, 784 00:55:05,722 --> 00:55:10,686 astronomy and monumental architectureof pyramids and temples. 785 00:55:20,404 --> 00:55:24,783 They even built an observatorybefore there were telescopes. 786 00:55:25,284 --> 00:55:28,287 They tracked the positionof celestial bodies. 787 00:55:29,746 --> 00:55:35,419 Their calendar was much more precisethan anything at this historical time. 788 00:55:37,588 --> 00:55:42,176 The Mayas had a deep fascinationof death and the afterlife. 789 00:55:43,093 --> 00:55:48,140 In their belief, there werenine underworlds and 13 heavens. 790 00:55:53,854 --> 00:55:56,648 Wanting to see some of the underworld, 791 00:55:56,732 --> 00:56:00,110 we descended to the bottomof a nearby cenote. 792 00:56:06,033 --> 00:56:11,038 Fátima Tec Pool,a cave expert and archaeologist, 793 00:56:11,121 --> 00:56:14,374 took us to one of the abodesof the rain god. 794 00:56:17,503 --> 00:56:21,089 This cenote was virtually unknownuntil very recently. 795 00:56:21,173 --> 00:56:24,801 Tell me, Fátima, what is the relationshipbetween the cenote, 796 00:56:24,885 --> 00:56:28,472 the cave here, and the ritualand belief of the Maya? 797 00:56:29,556 --> 00:56:32,309 This place is interestingbecause you can see 798 00:56:32,392 --> 00:56:36,021 how the concepts of waterand caves combine. 799 00:56:36,605 --> 00:56:39,024 And how the Mayans usedthese spaces for rituals. 800 00:56:39,566 --> 00:56:45,656 Inside, you can see walls which suggestthe Mayans used to make pilgrimages here 801 00:56:45,739 --> 00:56:47,783 to pass through these sacred walls. 802 00:56:47,866 --> 00:56:50,077 -Can we go in?-Of course, let's go. 803 00:56:58,585 --> 00:57:01,004 As the caves are seen asentrances to the underworld, 804 00:57:01,588 --> 00:57:06,510 we can see here how they made use ofthe natural form of the cave, 805 00:57:06,593 --> 00:57:09,596 to make ritual depositsof human remains, 806 00:57:09,680 --> 00:57:13,809 possibly an ancestor of a Mayan family. 807 00:57:13,892 --> 00:57:17,396 -What era are they from?-Possibly the Preclassic. 808 00:57:19,648 --> 00:57:22,734 We can also see this portal. 809 00:57:22,818 --> 00:57:24,987 This takes us further into the underworld. 810 00:57:26,113 --> 00:57:29,283 There's something else interesting... 811 00:57:35,205 --> 00:57:37,040 A human finger bone. 812 00:57:38,083 --> 00:57:42,087 Deposited here in part of the wall. 813 00:57:42,171 --> 00:57:47,050 Look closely and you can see ashes,possibly a kind of mortuary treatment, 814 00:57:47,676 --> 00:57:50,679 before being placed in the wall. 815 00:57:50,762 --> 00:57:53,682 Is it safe for human beingsto enter the underworld, 816 00:57:53,765 --> 00:57:55,058 the abode of the gods? 817 00:57:55,142 --> 00:57:56,894 Yes, of course! 818 00:58:14,203 --> 00:58:18,040 We timed our visitwith the Mexican Day of the Dead. 819 00:58:18,790 --> 00:58:21,502 For the Mayans, death was an obsession. 820 00:58:22,461 --> 00:58:26,507 There are endless friezeswith nothing but skulls. 821 00:58:39,853 --> 00:58:42,481 Mérida, the central cemetery. 822 00:58:43,023 --> 00:58:46,652 All this within the perimeterof the Chicxulub crater. 823 00:58:49,404 --> 00:58:52,950 The dead leave their gravesand join the living. 824 01:01:23,934 --> 01:01:25,811 We are here in the serene park 825 01:01:25,894 --> 01:01:29,731 of the pope's summer residenceof Castel Gandolfo. 826 01:01:30,148 --> 01:01:33,861 However,serious science is being done here. 827 01:01:35,112 --> 01:01:41,368 There's an astronomical observatoryfamous for its photographic celestial map. 828 01:01:42,786 --> 01:01:48,292 Right next to the residence, Lake Albano,a formidable volcanic crater. 829 01:01:51,128 --> 01:01:56,550 The director of the observatoryis a Jesuit, Brother Guy Consolmagno. 830 01:01:57,759 --> 01:02:00,971 He's one of the foremost scholarsin meteoritics. 831 01:02:01,972 --> 01:02:05,267 Brother Guy, at the heartof the Vatican Observatory 832 01:02:05,350 --> 01:02:07,352 is this wonderful meteorite collection. 833 01:02:07,436 --> 01:02:09,188 Quite a historical collection. 834 01:02:09,271 --> 01:02:10,439 I certainly think so. 835 01:02:10,522 --> 01:02:13,567 This is the stuff I've been working onfor, now, nearly 30 years. 836 01:02:13,650 --> 01:02:15,569 Is this why you came here initially? 837 01:02:15,652 --> 01:02:17,613 I didn't choose to come here. 838 01:02:17,696 --> 01:02:20,282 I did this under a vow of obedience. 839 01:02:20,365 --> 01:02:23,202 I had been a scientistand then entered the Jesuits 840 01:02:23,285 --> 01:02:26,955 and thought I was gonna be teachingat a school like maybe Georgetown. 841 01:02:27,039 --> 01:02:30,751 But under obediencethey ordered me to come to Rome 842 01:02:30,834 --> 01:02:34,087 and eat that terrible foodand look at this miserable scenery. 843 01:02:34,171 --> 01:02:37,424 And, oh, yes, there's a collectionof a thousand meteorites. 844 01:02:37,508 --> 01:02:39,968 They didn't knowthat the meteorites were here. 845 01:02:40,052 --> 01:02:43,138 They didn't know that my expertisewas meteorites. 846 01:02:43,222 --> 01:02:46,099 It was one of those divine coincidences. 847 01:02:46,183 --> 01:02:48,644 It's phenomenal that we've got meteorites, 848 01:02:48,727 --> 01:02:53,023 that we've got pieces of outer spacethat have visited us here on Earth, 849 01:02:53,106 --> 01:02:55,400 and that we can tellthat they're not from the Earth, 850 01:02:55,484 --> 01:02:58,403 that they're made, chemically,of completely different materials, 851 01:02:58,487 --> 01:03:01,073 that they were formed4.5 billion years ago. 852 01:03:01,156 --> 01:03:04,243 That we have the abilityto understand these things 853 01:03:04,326 --> 01:03:05,994 is itself a miracle. 854 01:03:06,703 --> 01:03:11,166 And you would find it perfectly reasonablethat life is elsewhere in the universe, 855 01:03:11,250 --> 01:03:14,253 life on Earthmay have originated elsewhere? 856 01:03:14,336 --> 01:03:17,381 It's possible. I don't know.I don't have the data. 857 01:03:17,464 --> 01:03:19,675 You know, people will sometimes ask me, 858 01:03:19,758 --> 01:03:22,219 do I believe that there's life elsewherein the universe? 859 01:03:22,302 --> 01:03:24,429 And I think that's the right wayto ask it. 860 01:03:24,513 --> 01:03:27,850 It's a matter of belief.I don't have the data. 861 01:03:28,559 --> 01:03:30,644 But if you were to come to me,as a scientist, 862 01:03:30,727 --> 01:03:32,771 saying you wanted resourcesto look for life, 863 01:03:32,855 --> 01:03:35,148 and you had a great project,I'd say, "Go for it." 864 01:03:35,232 --> 01:03:37,150 On the other hand, if you were sayingyou wanted to study 865 01:03:37,234 --> 01:03:39,820 little green mencoming out of a flying saucer, 866 01:03:39,903 --> 01:03:42,322 then I'm not so sureI'd go along with that. 867 01:03:42,406 --> 01:03:47,035 But if the green men arrived on Earth,would you consider baptizing them? 868 01:03:47,452 --> 01:03:48,745 Only if they ask. 869 01:03:50,831 --> 01:03:54,835 Brother Guy invited usto see the historical telescope. 870 01:03:54,918 --> 01:03:57,588 ...that were commissionedto photograph the entire sky 871 01:03:57,671 --> 01:03:59,298 and make a photographic atlas. 872 01:03:59,798 --> 01:04:02,801 Why, throughout so much of historyand around the world, 873 01:04:02,885 --> 01:04:06,597 have people thought of heavenas up there? 874 01:04:07,973 --> 01:04:09,641 I don't know, but it's certainly true. 875 01:04:09,725 --> 01:04:11,518 I mean, there are so many languages 876 01:04:11,602 --> 01:04:14,605 where the word for "sky" and the wordfor "heaven" are the same word. 877 01:04:15,939 --> 01:04:17,149 All I can think of-- 878 01:04:17,232 --> 01:04:20,611 and maybe, you know, a professionalwould come up with a better answer-- 879 01:04:20,694 --> 01:04:24,364 all I can think of is looking at the stars 880 01:04:24,448 --> 01:04:29,745 give you that sense of out-of-yourselfthat you need 881 01:04:29,828 --> 01:04:32,623 to be able to be readyto encounter a god. 882 01:04:33,790 --> 01:04:35,918 When you see a shooting star today, 883 01:04:36,001 --> 01:04:40,088 is it an interesting scientific factfor you, or do you gasp in wonder? 884 01:04:40,172 --> 01:04:42,299 Yes.

Yeah. 1019 01:12:56,418 --> 01:12:57,586 'Oumuamua? 1020 01:12:57,669 --> 01:12:59,880 'Oumuamua.So, it's actually a Hawaiian word. 1021 01:12:59,963 --> 01:13:01,965 It means "first messenger from afar." Yes. 1022 01:13:02,049 --> 01:13:03,050 Okay. 1023 01:13:03,759 --> 01:13:05,844 So it's actually a two-step process. 1024 01:13:05,928 --> 01:13:09,306 The computer software isn't perfect,and it still requires manual review, 1025 01:13:09,389 --> 01:13:10,849 and that's where I come in. 1026 01:13:10,933 --> 01:13:14,478 So my main responsibility is to reviewall the nightly detections. 1027 01:13:14,561 --> 01:13:16,313 And things that are real, 1028 01:13:16,396 --> 01:13:20,400 they would show up as eithera series of dots or trailed objects. 1029 01:13:20,484 --> 01:13:22,653 Are you the first person who's seen this? 1030 01:13:22,736 --> 01:13:25,322 Yes. So while the observerscollect the data, 1031 01:13:25,405 --> 01:13:28,492 I'm actually the first personon the planet to review and see this, 1032 01:13:28,575 --> 01:13:30,452 and my submitting it would sound the alarm 1033 01:13:30,536 --> 01:13:32,871 if there was an objectthat was a hazard to the Earth. 1034 01:13:34,498 --> 01:13:37,543 The alarmwould instantly call the attention 1035 01:13:37,626 --> 01:13:41,255 of NASA's Planetary DefenseCoordination Office. 1036 01:13:42,089 --> 01:13:45,175 Only a few people know that it exists. 1037 01:13:45,884 --> 01:13:50,264 Responsible here is Dr. Kelly Fast,an astronomer. 1038 01:13:50,347 --> 01:13:52,516 I've heard you describe asteroids 1039 01:13:52,599 --> 01:13:54,101 as the vermin of the solar system. 1040 01:13:54,184 --> 01:13:55,769 Why do you call them that? 1041 01:13:56,478 --> 01:14:01,108 Well, certainly astronomers who arelooking at things besides asteroids... 1042 01:14:02,192 --> 01:14:03,652 they might be looking at their target, 1043 01:14:03,735 --> 01:14:08,031 and asteroids are going to photobombwhatever they're looking at. 1044 01:14:08,115 --> 01:14:11,118 So I guess from a point of view,if you're looking at something else, 1045 01:14:11,201 --> 01:14:13,412 then they are the verminof the solar system. 1046 01:14:14,121 --> 01:14:15,873 From our point of view at NASA, 1047 01:14:15,956 --> 01:14:20,586 they're fantastic for science,for spacecraft targets. 1048 01:14:20,669 --> 01:14:22,421 But we also want to keep an eye on them, 1049 01:14:22,504 --> 01:14:27,009 because it's never good when two thingsoccupy the same space at the same time. 1050 01:14:27,092 --> 01:14:30,804 So we want to know if any of themare going to intersect Earth's orbit 1051 01:14:30,888 --> 01:14:33,307 at a time when Earth is going to be there. 1052 01:14:33,390 --> 01:14:35,976 There's dust hitting Earth's atmosphereall the time. 1053 01:14:36,059 --> 01:14:37,936 We see shooting stars, 1054 01:14:38,020 --> 01:14:39,980 that's just dust burning upin the atmosphere. 1055 01:14:40,063 --> 01:14:43,025 But it's when things are larger, 1056 01:14:43,108 --> 01:14:45,903 when you get up tothe size of asteroids-- 1057 01:14:45,986 --> 01:14:49,865 Earth's atmosphere is fantasticfor burning things up, 1058 01:14:49,948 --> 01:14:52,159 but eventually things get too bigfor that to happen. 1059 01:14:52,242 --> 01:14:55,454 Chelyabinsk, 20 meters.There was devastation. 1060 01:14:56,246 --> 01:14:58,707 Tunguska, Siberia, in 1908. 1061 01:14:58,790 --> 01:15:02,294 That was probably a 40-meter asteroid. 1062 01:15:04,379 --> 01:15:08,342 Eighty million treeswere flattened by the blast. 1063 01:15:08,425 --> 01:15:13,096 But not a single grain of the asteroidhas ever been discovered. 1064 01:15:16,225 --> 01:15:19,937 And defense? What can we doif there's a big sucker coming in at us? 1065 01:15:20,020 --> 01:15:21,980 What can we do about it? 1066 01:15:22,064 --> 01:15:24,691 Well, yeah, the best defenseis preparation. 1067 01:15:24,775 --> 01:15:26,652 And so finding them first-- 1068 01:15:26,735 --> 01:15:29,363 You don't know how to mount a defenseuntil you find them. 1069 01:15:29,446 --> 01:15:31,490 So that is the first order of business. 1070 01:15:31,573 --> 01:15:34,076 And that is going onwith ground-based surveys. 1071 01:15:34,535 --> 01:15:36,203 If you think of it as: 1072 01:15:36,286 --> 01:15:37,120 You've got the Sun, 1073 01:15:37,204 --> 01:15:39,957 you've got the Earth and the other planetsgoing around the Sun, 1074 01:15:40,040 --> 01:15:41,208 like being on a racetrack. 1075 01:15:41,291 --> 01:15:44,169 And then you've got all the asteroidsgoing around the Sun on the racetrack. 1076 01:15:44,253 --> 01:15:47,005 And so there are many timeswhen they might come close together. 1077 01:15:47,089 --> 01:15:49,925 In fact, we have that often,where there's a "close approach," 1078 01:15:50,008 --> 01:15:53,011 where an asteroidcomes close to Earth, which-- 1079 01:15:53,095 --> 01:15:56,390 Close might mean, you know,many lunar distances away. 1080 01:15:56,849 --> 01:15:58,517 But let's say this is really large. 1081 01:15:58,600 --> 01:16:02,062 It's a very large asteroid,and you don't have a lot of time. 1082 01:16:02,688 --> 01:16:06,233 There are the moviesthat show blowing them up. 1083 01:16:06,316 --> 01:16:09,361 You don't necessarily have to do that.You still need a good push. 1084 01:16:09,444 --> 01:16:12,823 And you could usea nuclear explosive device 1085 01:16:12,906 --> 01:16:14,283 that is used in some of these movies. 1086 01:16:14,366 --> 01:16:18,245 But the idea is you would detonate itnext to the asteroid, 1087 01:16:18,328 --> 01:16:23,375 and the energy from that detonationwould irradiate the surface, 1088 01:16:23,458 --> 01:16:26,211 and the material that blows offthe surface of the asteroid 1089 01:16:26,295 --> 01:16:28,297 would give it that pushin the other direction. 1090 01:16:30,340 --> 01:16:32,885 A softer, unaggressive approach 1091 01:16:32,968 --> 01:16:38,307 was actually performed bya Japanese probe on Asteroid Ryugu. 1092 01:16:39,391 --> 01:16:41,602 How small the asteroid is 1093 01:16:41,685 --> 01:16:46,815 we can tell from the size of the shadowthe probe casts on its surface. 1094 01:16:49,651 --> 01:16:53,906 Gravity is so minimalthat the softest of landings 1095 01:16:53,989 --> 01:16:58,702 already threw great quantitiesof debris away from it, into space. 1096 01:17:00,621 --> 01:17:03,749 Right herewe see how meteorites originate. 1097 01:17:05,042 --> 01:17:08,962 The probe itself is alreadyon its way back to Earth, 1098 01:17:09,046 --> 01:17:12,799 bringing a single gramscooped from the asteroid. 1099 01:17:13,842 --> 01:17:18,138 But for bigger specimens,Antarctica is paradise. 1100 01:17:21,767 --> 01:17:25,062 It is not that more rocks fall herethan elsewhere. 1101 01:17:25,812 --> 01:17:31,401 They are visible on the vast glaciersthat cover almost the entire continent 1102 01:17:31,485 --> 01:17:34,571 that is larger than the United States. 1103 01:17:35,989 --> 01:17:41,078 We were invited to join the huntby South Korean scientists. 1104 01:17:41,745 --> 01:17:45,249 Their station, named Jang Bogo, 1105 01:17:45,332 --> 01:17:49,837 at the coast of East Antarctica,houses about 50 people. 1106 01:17:53,048 --> 01:17:57,052 The austral summer seasonlasts nearly five months, 1107 01:17:57,469 --> 01:18:00,013 during which the Sun never goes down. 1108 01:18:03,183 --> 01:18:06,895 Inside, it is more spaciousthan we anticipated. 1109 01:18:08,522 --> 01:18:13,610 Only a few miles away,six men of Scott's last expedition 1110 01:18:13,694 --> 01:18:19,825 endured a whole winter huddlingin a snow cave just nine feet across. 1111 01:18:20,659 --> 01:18:23,620 They were starving and freezingin squalor, 1112 01:18:23,704 --> 01:18:28,417 surviving on seal meatand a ration of one biscuit a day. 1113 01:18:29,418 --> 01:18:31,837 From diaries of Scott's men, 1114 01:18:31,920 --> 01:18:37,634 we know they dreamt of banquets thatwere ripped away from their ready forks. 1115 01:18:37,718 --> 01:18:42,014 Only one man managed in his dreamto actually eat, 1116 01:18:42,097 --> 01:18:45,767 and he was rightfully hatedby his comrades for this. 1117 01:18:50,147 --> 01:18:53,317 But we were not herefor lobster and kimchi. 1118 01:18:53,817 --> 01:18:57,988 We were itching to flyto the Polar Plateau in the interior. 1119 01:18:58,822 --> 01:19:02,910 We knew there wasan overland expedition of trucks 1120 01:19:02,993 --> 01:19:05,954 that had left our station three weeks ago 1121 01:19:06,038 --> 01:19:10,626 and was nearing the meteoritehunting grounds on the blue ice. 1122 01:19:20,928 --> 01:19:25,766 But first the helicopter has to climb upsome 2,000 meters. 1123 01:19:26,266 --> 01:19:30,729 From the station at the coastto the ice plateau of the continent, 1124 01:19:30,812 --> 01:19:34,691 we are flying over glacier icecascading down. 1125 01:19:35,400 --> 01:19:37,569 Imagine crossing this on foot. 1126 01:19:38,237 --> 01:19:41,281 Each of these wildly tossed boulders 1127 01:19:41,365 --> 01:19:43,992 is larger than an apartment building, 1128 01:19:44,076 --> 01:19:47,621 and the mass is constantly flowingtowards the sea. 1129 01:19:51,416 --> 01:19:53,794 Finally we reach the Plateau. 1130 01:19:54,628 --> 01:19:59,842 Only a few mountains remain,sticking out of the ice like islands. 1131 01:20:01,677 --> 01:20:06,390 It felt like entering into a worldthat was not our planet. 1132 01:20:11,645 --> 01:20:14,523 From here begins the immense loneliness 1133 01:20:14,606 --> 01:20:20,737 of a vast continent covered by icetwo to four kilometers thick. 1134 01:20:26,285 --> 01:20:30,539 Through GPS data,we knew the position of the caravan. 1135 01:20:31,999 --> 01:20:33,959 They were expecting us. 1136 01:20:52,978 --> 01:20:56,315 We were so looking forwardto meet Jong Ik Lee, 1137 01:20:56,398 --> 01:20:58,692 the leader of this expedition. 1138 01:20:59,526 --> 01:21:03,280 He was the one who invited usto Antarctica, 1139 01:21:03,363 --> 01:21:06,325 and it felt like meeting an old friend. 1140 01:21:07,576 --> 01:21:09,328 -I didn't think you'd make it.-Yes, yes. 1141 01:21:09,411 --> 01:21:11,330 I didn't know that we would make it. 1142 01:21:11,413 --> 01:21:13,290 My dream... 1143 01:21:13,373 --> 01:21:17,878 We had seen footage he shotclose to here a few years earlier. 1144 01:21:18,962 --> 01:21:21,548 He had found a large meteorite, 1145 01:21:21,632 --> 01:21:26,220 and we fell in love with him,seeing his ecstasy of discovery. 1146 01:21:27,012 --> 01:21:29,681 This is science at its best. 1147 01:22:10,180 --> 01:22:12,474 Okay, down. 1148 01:22:21,024 --> 01:22:25,445 Something else I like aboutthis highly charged emotional moment, 1149 01:22:25,529 --> 01:22:30,075 something the stupid doctrineof film schools would never allow. 1150 01:22:31,702 --> 01:22:34,454 Watch the background. A figure enters. 1151 01:22:34,538 --> 01:22:38,458 No recognizable motivation,wrong timing, 1152 01:22:38,542 --> 01:22:40,544 rear end approaching. 1153 01:22:59,062 --> 01:23:00,856 Back to the present. 1154 01:23:01,690 --> 01:23:06,195 Along with us, Jong Ik's wife,Mi Jung, had arrived, 1155 01:23:06,278 --> 01:23:09,448 herself a renowned polar geologist. 1156 01:23:21,251 --> 01:23:23,128 Husband and wife reunited. 1157 01:23:24,588 --> 01:23:29,009 Minutes after our arrivalwe found our first meteorite. 1158 01:23:30,260 --> 01:23:34,097 The sheer, blank ice,not covered with snow, 1159 01:23:34,181 --> 01:23:36,767 is the ideal terrain to spot them. 1160 01:23:37,684 --> 01:23:42,940 The gigantic mass of ice is moving slowly,like a conveyor belt 1161 01:23:43,023 --> 01:23:48,612 and exposes stones that may have fallenhundreds of thousands of years ago. 1162 01:23:51,782 --> 01:23:55,369 Most of the meteoritesare carried all the way to the ocean. 1163 01:23:55,911 --> 01:24:02,000 But where the glacier is deflected upwardsby a mountain range deep down there, 1164 01:24:02,084 --> 01:24:06,255 the ice evaporates,leaving its cargo at the surface. 1165 01:24:08,090 --> 01:24:11,593 Every stone out here is a meteorite. 1166 01:24:55,345 --> 01:24:58,473 Watch the man on the right.He found something. 1167 01:25:12,154 --> 01:25:14,948 The lucky one turned out to be Clive. 1168 01:25:15,574 --> 01:25:18,619 It may look staged, but it was really him. 1169 01:25:23,415 --> 01:25:29,296 This is it!
