WEBVTT 00:00:17.640 --> 00:00:18.920 The universe… 00:00:20.160 --> 00:00:22.000 …has provided our planet 00:00:22.080 --> 00:00:25.200 with all the ingredients needed for life to emerge… 00:00:26.240 --> 00:00:27.360 …and flourish. 00:00:29.520 --> 00:00:31.440 The energy flowing through us. 00:00:36.480 --> 00:00:38.520 The daily rhythms we follow. 00:00:41.400 --> 00:00:43.880 The elements we are made of. 00:00:47.280 --> 00:00:49.800 But behind all these wonders… 00:00:50.920 --> 00:00:52.840 …lies a mysterious force… 00:00:56.040 --> 00:00:58.520 …that makes all of this possible. 00:01:01.040 --> 00:01:01.920 Gravity. 00:01:08.600 --> 00:01:10.880 It holds everything in place. 00:01:15.760 --> 00:01:17.480 It builds every star… 00:01:20.600 --> 00:01:22.240 …and shapes every planet. 00:01:26.480 --> 00:01:28.600 And guides every life. 00:01:31.000 --> 00:01:33.400 It's the ultimate force of attraction. 00:01:35.480 --> 00:01:40.240 So profound, it will bring two young souls together… 00:01:42.680 --> 00:01:45.880 in their search for the perfect mate. 00:02:13.720 --> 00:02:18.880 In the Southern Ocean, over 2,000 kilometers from Antarctica… 00:02:21.680 --> 00:02:25.320 …lies the windswept island of South Georgia. 00:02:29.920 --> 00:02:31.440 Home to a colony 00:02:32.840 --> 00:02:35.480 of half a million king penguins. 00:02:44.080 --> 00:02:47.080 And it's a big day for two of them. 00:02:52.600 --> 00:02:53.600 New parents. 00:02:59.040 --> 00:03:00.680 For over 50 days… 00:03:03.400 --> 00:03:07.480 they've been taking turns keeping their precious cargo safe… 00:03:10.920 --> 00:03:12.240 …and warm. 00:03:14.920 --> 00:03:19.520 And today, it's time to welcome their baby son into the world. 00:03:30.800 --> 00:03:31.680 Little Rocky… 00:03:35.080 --> 00:03:36.960 meet big world. 00:03:44.920 --> 00:03:47.440 And on the other side of the island, 00:03:48.320 --> 00:03:50.840 another little chick is stepping out. 00:03:54.720 --> 00:03:55.880 A girl. 00:03:57.200 --> 00:03:58.120 Paloma. 00:04:04.920 --> 00:04:09.240 Rocky and Paloma don't know it yet, but they are destined for each other. 00:04:20.800 --> 00:04:24.120 A force of attraction beyond their control 00:04:25.520 --> 00:04:27.080 will bring them together. 00:04:35.920 --> 00:04:40.600 This force not only hugs Rocky and Paloma firmly to the ground… 00:04:45.800 --> 00:04:48.680 …it hugs our atmosphere to the planet. 00:04:55.000 --> 00:04:57.000 It keeps Earth orbiting the Sun… 00:05:03.040 --> 00:05:08.160 …the Sun rotating around the center of our galaxy… 00:05:09.920 --> 00:05:14.200 …and galaxies dancing and swirling around each other 00:05:16.040 --> 00:05:18.280 on the grandest of scales. 00:05:21.720 --> 00:05:25.360 Gravity holds all the pieces of our universe together, 00:05:26.600 --> 00:05:28.040 connecting everything… 00:05:31.600 --> 00:05:33.960 …from the most distant star… 00:05:41.640 --> 00:05:43.280 …to the tiniest penguin. 00:05:47.680 --> 00:05:52.400 But Rocky and Paloma aren't thinking about their place in the cosmos… 00:05:56.440 --> 00:05:57.920 …just their next meal. 00:06:03.960 --> 00:06:07.160 It's taking all the efforts of their devoted parents… 00:06:09.840 --> 00:06:12.400 to feed their insatiable appetites. 00:06:20.960 --> 00:06:22.080 It's a thankless… 00:06:25.520 --> 00:06:27.040 and never-ending task. 00:06:42.640 --> 00:06:47.120 They're doing everything they can to fatten their chicks in time for winter. 00:06:50.040 --> 00:06:53.120 Because as Rocky and Paloma have been growing bigger… 00:06:55.200 --> 00:06:58.440 the days have been growing shorter. 00:07:04.280 --> 00:07:07.000 Food is becoming scarce. 00:07:11.880 --> 00:07:14.160 Their parents must leave the island… 00:07:18.320 --> 00:07:21.480 and travel hundreds of kilometers out to sea… 00:07:23.840 --> 00:07:25.120 to hunt for food… 00:07:27.160 --> 00:07:29.400 leaving their precious chicks for months 00:07:30.000 --> 00:07:32.360 to fend for themselves. 00:07:43.440 --> 00:07:46.040 Paloma's cries go unanswered… 00:07:48.200 --> 00:07:50.880 as the first, loneliest night sets in. 00:07:54.080 --> 00:07:56.880 The darkest moment in a penguin chick's life. 00:08:05.200 --> 00:08:09.680 But it's nothing compared to our universe's darkest moments… 00:08:12.800 --> 00:08:15.480 because long before there was an Earth, 00:08:17.280 --> 00:08:18.400 a Sun, 00:08:19.640 --> 00:08:20.880 or stars… 00:08:25.520 --> 00:08:27.400 there was no light at all. 00:08:37.200 --> 00:08:41.400 The universe was just a dark, dense web of gas. 00:08:49.280 --> 00:08:53.280 But here, gravity began to work its magic. 00:08:56.600 --> 00:09:01.000 From this gravity came everything. 00:09:07.400 --> 00:09:09.520 Parts of the web were pulled together… 00:09:12.000 --> 00:09:13.640 into clumps of matter… 00:09:17.160 --> 00:09:19.640 …that grew and grew… 00:09:24.920 --> 00:09:29.840 until they got so big, they collapsed in on themselves… 00:09:32.000 --> 00:09:33.480 …bursting into life… 00:09:38.680 --> 00:09:42.160 …as the very first stars. 00:09:50.800 --> 00:09:52.160 Gravity kept working, 00:09:52.880 --> 00:09:57.440 sculpting the primordial web into more and more stars… 00:09:59.920 --> 00:10:02.000 pulling them toward each other 00:10:03.520 --> 00:10:06.280 and spinning them into vast galaxies. 00:10:13.800 --> 00:10:14.720 From nothing, 00:10:15.680 --> 00:10:19.400 gravity shaped an entire universe of possibility… 00:10:22.760 --> 00:10:25.800 that still speckles our night sky. 00:10:35.800 --> 00:10:40.480 But light from distant stars won't keep penguin chicks warm. 00:10:43.680 --> 00:10:45.280 With their parents at sea, 00:10:46.160 --> 00:10:49.120 Rocky and Paloma are losing weight, 00:10:50.560 --> 00:10:53.800 becoming more and more vulnerable. 00:11:10.400 --> 00:11:12.640 The chicks only refuge from the cold 00:11:13.480 --> 00:11:14.840 is their fluffy down 00:11:16.520 --> 00:11:17.440 and each other. 00:11:19.600 --> 00:11:23.680 Their survival hinges on a precise, elegant dance 00:11:23.760 --> 00:11:25.480 between one star 00:11:26.320 --> 00:11:27.440 and one planet, 00:11:29.320 --> 00:11:34.080 choreographed by gravity over four and a half billion years ago. 00:11:43.800 --> 00:11:47.720 Out of the dust and gas left over from the formation of the Sun… 00:11:51.240 --> 00:11:54.160 …gravity pulled bits and pieces of rubble together… 00:12:01.880 --> 00:12:05.080 …molding them over time into a planet. 00:12:15.920 --> 00:12:19.280 It was unrecognizable from the home we know now… 00:12:21.720 --> 00:12:24.240 but it had all the potential for life… 00:12:28.040 --> 00:12:31.800 bathed in the glow of our newborn Sun. 00:12:36.520 --> 00:12:41.400 That same Sun, billions of years later, is now rising… 00:12:45.640 --> 00:12:49.080 …signaling to Rocky and Paloma's parents, 00:12:49.960 --> 00:12:52.560 it's time to return to South Georgia… 00:12:56.960 --> 00:13:01.080 with their bellies full of fish. 00:13:08.600 --> 00:13:11.040 As the sun warms the beaches, 00:13:11.120 --> 00:13:14.480 the island is transformed into a haven once again. 00:13:19.600 --> 00:13:22.880 But making it to shore was the easy part. 00:13:25.320 --> 00:13:28.480 Rocky's parents now have to find their baby 00:13:29.240 --> 00:13:31.760 amongst thousands of others. 00:13:42.600 --> 00:13:47.560 Up the coast, Paloma's parents lock onto her special call… 00:13:48.600 --> 00:13:50.720 …and quickly find her in the crowd. 00:13:58.240 --> 00:14:01.320 And finally, Rocky's parents also hear 00:14:01.840 --> 00:14:03.440 the unmistakable cry… 00:14:05.600 --> 00:14:07.080 …of their little one. 00:14:13.480 --> 00:14:17.600 His voice has a unique signature only his parents can identify. 00:14:21.680 --> 00:14:23.200 It's a family reunion. 00:14:25.240 --> 00:14:27.240 And two baby bellies 00:14:28.280 --> 00:14:30.200 are full at last. 00:14:36.440 --> 00:14:40.160 From the first stars to the birth of our galaxy, 00:14:40.240 --> 00:14:42.240 Sun, and planet, 00:14:43.480 --> 00:14:46.720 gravity set the stage for life. 00:14:53.800 --> 00:14:56.120 But for Earth to become the home we know, 00:14:57.840 --> 00:15:01.280 gravity would need to send a bit of chaos our way… 00:15:07.320 --> 00:15:10.680 …so evolution could run riot. 00:15:20.200 --> 00:15:22.000 Several months have passed. 00:15:23.680 --> 00:15:25.800 Rocky's now doubled in size… 00:15:28.000 --> 00:15:29.400 and is ready for love. 00:15:30.920 --> 00:15:33.680 But he won't truly be an eligible bachelor… 00:15:35.720 --> 00:15:39.080 until he's become fit and handsome. 00:15:43.320 --> 00:15:45.600 First, a new outfit. 00:15:50.680 --> 00:15:53.360 Trading in his childish, fluffy feathers… 00:15:55.880 --> 00:15:58.200 for a shiny, waterproof coat… 00:16:00.920 --> 00:16:02.880 he's ready for his first swim. 00:16:16.160 --> 00:16:17.960 On the other end of the beach, 00:16:19.760 --> 00:16:21.800 Paloma is ready to launch as well. 00:16:31.560 --> 00:16:34.800 After only knowing dry land their whole lives, 00:16:36.080 --> 00:16:38.480 it's an intimidating moment for both. 00:16:43.000 --> 00:16:44.840 Rocky thinks he's swimming… 00:16:49.000 --> 00:16:51.760 but Paloma actually is. 00:17:03.480 --> 00:17:07.480 Rocky finally figures out he needs to be in the water. 00:17:12.680 --> 00:17:16.360 These young birds will be gone for the next two years… 00:17:18.960 --> 00:17:21.600 on their own separate journeys. 00:17:26.560 --> 00:17:29.080 There are great riches awaiting them in the ocean… 00:17:32.320 --> 00:17:33.400 thanks to gravity… 00:17:36.360 --> 00:17:38.280 …and our nearest neighbor. 00:17:49.480 --> 00:17:51.760 Not long after our planet formed… 00:17:55.120 --> 00:17:57.640 it collided with another young world. 00:18:13.360 --> 00:18:15.200 And out of the orbiting debris… 00:18:20.960 --> 00:18:24.320 …gravity formed Earth's traveling companion… 00:18:29.000 --> 00:18:29.840 the Moon. 00:18:36.680 --> 00:18:40.240 The impact knocked the young Earth onto its side… 00:18:41.560 --> 00:18:44.040 -…and threw it into turmoil… 00:18:46.040 --> 00:18:48.800 lurching and spinning wildly. 00:18:52.280 --> 00:18:54.440 But over billions of years, 00:18:54.520 --> 00:18:58.320 the gravitational tug of the Moon tamed the Earth. 00:18:59.640 --> 00:19:01.760 The Moon drifted away. 00:19:02.920 --> 00:19:05.000 Earth's rotation slowed… 00:19:07.400 --> 00:19:10.400 which transformed Earth's story. 00:19:15.200 --> 00:19:19.320 Because slower spin meant longer days… 00:19:22.000 --> 00:19:26.400 and, therefore, more hours of continuous sunshine 00:19:26.480 --> 00:19:28.640 penetrated the oceans… 00:19:40.120 --> 00:19:45.400 …creating the conditions for the first life to get a foothold. 00:19:52.000 --> 00:19:56.160 The first step in an underwater labyrinth of life 00:19:57.000 --> 00:19:59.320 that grew and grew… 00:20:05.360 --> 00:20:10.160 …eventually filling the oceans with unimaginable wonders. 00:20:24.560 --> 00:20:28.000 Wonders that today provide a rich ecosystem 00:20:29.000 --> 00:20:31.520 for two very hungry penguins… 00:20:35.120 --> 00:20:37.320 hundreds of kilometers apart 00:20:38.000 --> 00:20:39.280 in the open ocean. 00:20:44.040 --> 00:20:47.400 Paloma has reached the polar front… 00:20:52.240 --> 00:20:56.520 where the Southern Ocean meets the warmer waters of the Atlantic, 00:20:56.600 --> 00:20:59.600 Pacific, and Indian Oceans. 00:21:04.480 --> 00:21:08.160 Here, nutrients are churned up from below, 00:21:09.320 --> 00:21:11.720 supporting thousands of species… 00:21:17.000 --> 00:21:22.200 including lantern fish, a favorite of the king penguin. 00:21:27.160 --> 00:21:29.040 They live deep underwater. 00:21:32.760 --> 00:21:34.760 But that's no problem for Paloma. 00:21:36.560 --> 00:21:40.400 She's able to hunt 300 meters below the surface. 00:22:02.840 --> 00:22:06.840 Penguins are uniquely adapted to dive and hunt at great depth. 00:22:10.160 --> 00:22:14.320 But to understand how these remarkable adaptations came about, 00:22:16.280 --> 00:22:21.080 you need to know what gravity had been up to 66 million years ago. 00:22:31.680 --> 00:22:35.360 In the cold outer reaches of the solar system, 00:22:36.040 --> 00:22:39.360 millions of chunks of ice and rock orbit the Sun. 00:22:42.880 --> 00:22:45.680 Most of the time, these asteroids are no trouble. 00:22:54.280 --> 00:22:56.800 But sometimes they are. 00:23:00.720 --> 00:23:03.560 In the outer region of the asteroid belt, 00:23:04.840 --> 00:23:08.600 one particular rock, ten kilometers across, 00:23:09.360 --> 00:23:12.680 was warmed by the Sun over millennia. 00:23:16.880 --> 00:23:18.160 And bit by bit, 00:23:19.040 --> 00:23:25.200 the warming began to shift this asteroid, called Chicxulub, out of its orbit… 00:23:28.120 --> 00:23:29.640 until gravity took hold… 00:23:32.000 --> 00:23:33.840 pulling it in toward the Sun… 00:23:38.040 --> 00:23:41.320 sending it on a collision course with Earth… 00:23:48.160 --> 00:23:51.600 …at 72,000 kilometers an hour. 00:24:00.520 --> 00:24:04.840 The impact triggered a superheated wave of plasma… 00:24:08.360 --> 00:24:12.360 …causing wildfires and devastation across the planet… 00:24:15.160 --> 00:24:16.800 blocking out the Sun. 00:24:19.520 --> 00:24:23.080 Three-quarters of Earth's species were obliterated. 00:24:25.680 --> 00:24:28.200 It was bad news for the dinosaurs… 00:24:30.200 --> 00:24:33.840 but good news for the king penguin. 00:24:39.840 --> 00:24:41.400 Smaller and lighter, 00:24:42.080 --> 00:24:44.720 birds were able to survive the impact. 00:24:46.920 --> 00:24:50.280 They took to the skies and diversified. 00:24:53.640 --> 00:24:55.640 With large predators gone… 00:24:58.360 --> 00:25:01.120 the oceans abounded with fish. 00:25:05.200 --> 00:25:09.120 The penguin's ancestors became expert divers, 00:25:10.960 --> 00:25:12.240 diving deeper 00:25:13.360 --> 00:25:15.160 and staying down longer 00:25:16.720 --> 00:25:22.800 until, ultimately, they lost the ability to fly altogether. 00:25:28.880 --> 00:25:30.960 From soaring through the skies… 00:25:34.880 --> 00:25:37.000 to soaring through the oceans. 00:25:42.680 --> 00:25:45.080 Invaluable adaptations 00:25:45.160 --> 00:25:48.800 that Rocky and Paloma have put to good use. 00:25:53.800 --> 00:25:56.320 Fitter and stronger, 00:25:56.400 --> 00:25:59.760 they are now ready to return to their home shores 00:25:59.840 --> 00:26:01.080 in search of a mate. 00:26:05.200 --> 00:26:07.480 But their homecoming is interrupted… 00:26:15.800 --> 00:26:16.720 …by orcas, 00:26:18.280 --> 00:26:21.080 the only whale known to eat penguins. 00:26:25.160 --> 00:26:27.880 Paloma shifts into top gear. 00:26:32.880 --> 00:26:35.400 It will be a race to the finish. 00:26:41.040 --> 00:26:42.320 Orcas are fast. 00:26:47.920 --> 00:26:50.480 But king penguins are built for speed. 00:27:12.800 --> 00:27:15.800 Paloma is too quick for her pursuer. 00:27:19.920 --> 00:27:24.280 But Rocky took cover in the kelp forests near the shore. 00:27:38.680 --> 00:27:42.200 And the hungry orca isn't going anywhere. 00:28:00.080 --> 00:28:01.480 Rocky sees his opening… 00:28:06.280 --> 00:28:07.720 and bolts for the shore. 00:28:11.200 --> 00:28:14.280 -He definitely knows how to swim now. 00:28:20.000 --> 00:28:23.560 Two long years roaming the sea, 00:28:24.280 --> 00:28:27.400 all for a chance to enter the great lottery. 00:28:29.120 --> 00:28:31.400 The search for love. 00:28:34.320 --> 00:28:38.760 Gravity shaped the Sun, Earth, and Moon… 00:28:41.400 --> 00:28:44.160 creating a stable home for life on our planet 00:28:45.200 --> 00:28:48.480 and steering evolution in new directions. 00:28:56.680 --> 00:29:00.680 But the ballad of Rocky and Paloma needs one more part… 00:29:03.200 --> 00:29:04.600 …created by gravity 00:29:06.240 --> 00:29:08.440 in the fiery heart of the Sun. 00:29:12.040 --> 00:29:12.920 Light. 00:29:17.240 --> 00:29:19.560 Our star only shines because, 00:29:19.640 --> 00:29:23.680 at its center, an intense battle is taking place. 00:29:28.040 --> 00:29:29.720 Gravity pulls inward… 00:29:31.720 --> 00:29:35.200 while intense pressure pushes back. 00:29:41.800 --> 00:29:43.600 This gravitational war…. 00:29:48.480 --> 00:29:51.640 …causes atoms to collide and fuse… 00:29:58.000 --> 00:30:00.400 …releasing tiny pockets of energy… 00:30:02.240 --> 00:30:05.080 …in the form of photons… 00:30:12.320 --> 00:30:15.880 …that not only shower the Earth with life-sustaining energy… 00:30:18.240 --> 00:30:22.280 but also bathe it in light. 00:30:26.920 --> 00:30:29.960 Light that contains its own hidden wonders. 00:30:33.000 --> 00:30:35.800 Because within every sunbeam 00:30:36.920 --> 00:30:38.040 is a rainbow. 00:30:41.400 --> 00:30:44.160 Each photon has a unique wavelength 00:30:45.440 --> 00:30:48.600 and interacts with the stuff our world is made of 00:30:49.120 --> 00:30:50.320 in a different way. 00:31:01.880 --> 00:31:04.640 Some wavelengths are absorbed. 00:31:06.160 --> 00:31:08.680 Others are reflected. 00:31:12.760 --> 00:31:18.000 How these light waves hit our eyes determines what colors we see. 00:31:22.400 --> 00:31:24.840 And this ability to perceive color 00:31:25.680 --> 00:31:29.680 plays a key role in the penguin dating game. 00:31:39.200 --> 00:31:43.480 Years of feasting at sea have made Rocky fit and strong. 00:31:48.120 --> 00:31:51.400 Traits he needs to display to attract a mate. 00:31:58.200 --> 00:32:01.200 Pigments that he synthesized himself 00:32:02.360 --> 00:32:04.800 color his feathers brilliant yellow… 00:32:07.000 --> 00:32:09.480 perfect for showing off his own flair 00:32:11.360 --> 00:32:16.800 and attracting the gaze of the one bird in this crowd… 00:32:22.000 --> 00:32:25.600 -…who only has eyes for him. 00:32:29.800 --> 00:32:30.640 Paloma. 00:32:44.520 --> 00:32:48.680 Starlight reflects onto the retina at the back of Paloma's eye. 00:32:55.000 --> 00:32:58.280 Here, millions of cone cells get to work 00:32:58.360 --> 00:33:00.480 decoding every wavelength… 00:33:07.000 --> 00:33:12.200 …which allows Paloma to distinguish one color from another. 00:33:16.480 --> 00:33:17.840 In the blink of an eye, 00:33:18.360 --> 00:33:22.600 these lovebirds are not only able to see their world 00:33:23.640 --> 00:33:26.280 but also understand it 00:33:27.800 --> 00:33:30.280 and find their soulmate. 00:33:36.840 --> 00:33:40.840 The courting then turns to a carefully choreographed dance. 00:33:43.680 --> 00:33:46.480 Each displaying their dazzling, yellow feathers… 00:33:50.920 --> 00:33:52.280 for the other to admire. 00:34:03.600 --> 00:34:05.600 Other suitors try their luck 00:34:05.680 --> 00:34:07.000 but to no avail. 00:34:12.600 --> 00:34:14.360 Because Rocky's yellow feathers… 00:34:16.560 --> 00:34:18.360 aren't his only selling point. 00:34:22.240 --> 00:34:23.520 By shaking his head… 00:34:26.280 --> 00:34:28.280 he encodes a secret message… 00:34:30.680 --> 00:34:32.680 in ultraviolet light. 00:34:35.120 --> 00:34:37.240 His beak catches the Sun 00:34:39.000 --> 00:34:40.720 and reflects its rays. 00:34:47.200 --> 00:34:49.360 And thanks to an extra cone cell… 00:34:51.760 --> 00:34:56.640 …Rocky and Paloma's eyes can see colors beyond our own. 00:34:58.240 --> 00:35:02.120 These UV signals win Paloma over. 00:35:04.040 --> 00:35:05.880 They're the perfect match. 00:35:12.840 --> 00:35:16.000 Raising a penguin chick is a grueling task 00:35:17.880 --> 00:35:21.480 that requires both parents to be in top form. 00:35:26.320 --> 00:35:29.760 Impressive yellow feathers and a flashy beak 00:35:29.840 --> 00:35:32.800 are proof of strength and ability, 00:35:34.320 --> 00:35:38.040 essential characteristics when it comes to bringing up a family. 00:35:41.360 --> 00:35:44.120 From all the thousands of other birds, 00:35:45.000 --> 00:35:46.840 Rocky and Paloma… 00:35:49.640 --> 00:35:51.280 have found each other. 00:36:00.880 --> 00:36:03.480 From the first ripples in the cosmic web… 00:36:09.560 --> 00:36:11.240 …to the birth of our Sun… 00:36:13.680 --> 00:36:14.560 planet, 00:36:15.840 --> 00:36:16.720 and Moon… 00:36:21.680 --> 00:36:25.000 …the impacts that have written Earth's history… 00:36:27.800 --> 00:36:33.160 …to the force that powers the Sun, painting our world in color… 00:36:35.280 --> 00:36:40.280 gravity has had a hand in all of it… 00:36:44.200 --> 00:36:48.200 guiding these two penguins to their special moment… 00:36:51.920 --> 00:36:54.080 …on this special island… 00:36:58.240 --> 00:37:02.120 where it's not long before something extra special 00:37:02.200 --> 00:37:03.640 is delivered to Earth. 00:37:04.800 --> 00:37:09.760 Rocky and Paloma are going to be parents themselves. 00:37:13.680 --> 00:37:15.440 Ushering in a new life 00:37:16.160 --> 00:37:19.080 and maybe even new romance… 00:37:21.880 --> 00:37:25.720 with gravity, as ever, helping to lead the way. 00:37:33.880 --> 00:37:35.440 All across the Earth, 00:37:36.440 --> 00:37:38.880 life is dazzling in its variety. 00:38:04.520 --> 00:38:07.520 It has taken 13.8 billion years 00:38:07.600 --> 00:38:10.880 to reach this one precious moment 00:38:10.960 --> 00:38:13.680 in time and space. 00:38:22.520 --> 00:38:25.720 Every animal made from the stars… 00:38:27.720 --> 00:38:29.800 synchronized with the planet, 00:38:31.440 --> 00:38:34.720 and sustained by gifts from the cosmos 00:38:34.800 --> 00:38:38.400 that only made it here by pure chance. 00:38:52.320 --> 00:38:53.920 All held in its place 00:38:54.000 --> 00:38:55.120 by the ultimate, 00:38:56.040 --> 00:38:58.960 the original force of attraction. 00:39:07.320 --> 00:39:09.520 The story of our universe 00:39:09.600 --> 00:39:14.440 is the story of how life came to be here on this planet… 00:39:17.880 --> 00:39:19.400 …we call home. 00:39:23.080 --> 00:39:27.120 A story that is still being written.
