1 00:00:17,640 --> 00:00:18,920 The universe… 2 00:00:20,160 --> 00:00:22,000 …has provided our planet 3 00:00:22,080 --> 00:00:25,200 with all the ingredients needed for life to emerge… 4 00:00:26,240 --> 00:00:27,360 …and flourish. 5 00:00:29,520 --> 00:00:31,440 The energy flowing through us. 6 00:00:36,480 --> 00:00:38,520 The daily rhythms we follow. 7 00:00:41,400 --> 00:00:43,880 The elements we are made of. 8 00:00:47,280 --> 00:00:49,800 But behind all these wonders… 9 00:00:50,920 --> 00:00:52,840 …lies a mysterious force… 10 00:00:56,040 --> 00:00:58,520 …that makes all of this possible. 11 00:01:01,040 --> 00:01:01,920 Gravity. 12 00:01:08,600 --> 00:01:10,880 It holds everything in place. 13 00:01:15,760 --> 00:01:17,480 It builds every star… 14 00:01:20,600 --> 00:01:22,240 …and shapes every planet. 15 00:01:26,480 --> 00:01:28,600 And guides every life. 16 00:01:31,000 --> 00:01:33,400 It's the ultimate force of attraction. 17 00:01:35,480 --> 00:01:40,240 So profound, it will bring two young souls together… 18 00:01:42,680 --> 00:01:45,880 in their search for the perfect mate. 19 00:02:13,720 --> 00:02:18,880 In the Southern Ocean, over 2,000 kilometers from Antarctica… 20 00:02:21,680 --> 00:02:25,320 …lies the windswept island of South Georgia. 21 00:02:29,920 --> 00:02:31,440 Home to a colony 22 00:02:32,840 --> 00:02:35,480 of half a million king penguins. 23 00:02:44,080 --> 00:02:47,080 And it's a big day for two of them. 24 00:02:52,600 --> 00:02:53,600 New parents. 25 00:02:59,040 --> 00:03:00,680 For over 50 days… 26 00:03:03,400 --> 00:03:07,480 they've been taking turns keeping their precious cargo safe… 27 00:03:10,920 --> 00:03:12,240 …and warm. 28 00:03:14,920 --> 00:03:19,520 And today, it's time to welcome their baby son into the world. 29 00:03:30,800 --> 00:03:31,680 Little Rocky… 30 00:03:35,080 --> 00:03:36,960 meet big world. 31 00:03:44,920 --> 00:03:47,440 And on the other side of the island, 32 00:03:48,320 --> 00:03:50,840 another little chick is stepping out. 33 00:03:54,720 --> 00:03:55,880 A girl. 34 00:03:57,200 --> 00:03:58,120 Paloma. 35 00:04:04,920 --> 00:04:09,240 Rocky and Paloma don't know it yet, but they are destined for each other. 36 00:04:20,800 --> 00:04:24,120 A force of attraction beyond their control 37 00:04:25,520 --> 00:04:27,080 will bring them together. 38 00:04:35,920 --> 00:04:40,600 This force not only hugs Rocky and Paloma firmly to the ground… 39 00:04:45,800 --> 00:04:48,680 …it hugs our atmosphere to the planet. 40 00:04:55,000 --> 00:04:57,000 It keeps Earth orbiting the Sun… 41 00:05:03,040 --> 00:05:08,160 …the Sun rotating around the center of our galaxy… 42 00:05:09,920 --> 00:05:14,200 …and galaxies dancing and swirling around each other 43 00:05:16,040 --> 00:05:18,280 on the grandest of scales. 44 00:05:21,720 --> 00:05:25,360 Gravity holds all the pieces of our universe together, 45 00:05:26,600 --> 00:05:28,040 connecting everything… 46 00:05:31,600 --> 00:05:33,960 …from the most distant star… 47 00:05:41,640 --> 00:05:43,280 …to the tiniest penguin. 48 00:05:47,680 --> 00:05:52,400 But Rocky and Paloma aren't thinking about their place in the cosmos… 49 00:05:56,440 --> 00:05:57,920 …just their next meal. 50 00:06:03,960 --> 00:06:07,160 It's taking all the efforts of their devoted parents… 51 00:06:09,840 --> 00:06:12,400 to feed their insatiable appetites. 52 00:06:20,960 --> 00:06:22,080 It's a thankless… 53 00:06:25,520 --> 00:06:27,040 and never-ending task. 54 00:06:42,640 --> 00:06:47,120 They're doing everything they can to fatten their chicks in time for winter. 55 00:06:50,040 --> 00:06:53,120 Because as Rocky and Paloma have been growing bigger… 56 00:06:55,200 --> 00:06:58,440 the days have been growing shorter. 57 00:07:04,280 --> 00:07:07,000 Food is becoming scarce. 58 00:07:11,880 --> 00:07:14,160 Their parents must leave the island… 59 00:07:18,320 --> 00:07:21,480 and travel hundreds of kilometers out to sea… 60 00:07:23,840 --> 00:07:25,120 to hunt for food… 61 00:07:27,160 --> 00:07:29,400 leaving their precious chicks for months 62 00:07:30,000 --> 00:07:32,360 to fend for themselves. 63 00:07:43,440 --> 00:07:46,040 Paloma's cries go unanswered… 64 00:07:48,200 --> 00:07:50,880 as the first, loneliest night sets in. 65 00:07:54,080 --> 00:07:56,880 The darkest moment in a penguin chick's life. 66 00:08:05,200 --> 00:08:09,680 But it's nothing compared to our universe's darkest moments… 67 00:08:12,800 --> 00:08:15,480 because long before there was an Earth, 68 00:08:17,280 --> 00:08:18,400 a Sun, 69 00:08:19,640 --> 00:08:20,880 or stars… 70 00:08:25,520 --> 00:08:27,400 there was no light at all. 71 00:08:37,200 --> 00:08:41,400 The universe was just a dark, dense web of gas. 72 00:08:49,280 --> 00:08:53,280 But here, gravity began to work its magic. 73 00:08:56,600 --> 00:09:01,000 From this gravity came everything. 74 00:09:07,400 --> 00:09:09,520 Parts of the web were pulled together… 75 00:09:12,000 --> 00:09:13,640 into clumps of matter… 76 00:09:17,160 --> 00:09:19,640 …that grew and grew… 77 00:09:24,920 --> 00:09:29,840 until they got so big, they collapsed in on themselves… 78 00:09:32,000 --> 00:09:33,480 …bursting into life… 79 00:09:38,680 --> 00:09:42,160 …as the very first stars. 80 00:09:50,800 --> 00:09:52,160 Gravity kept working, 81 00:09:52,880 --> 00:09:57,440 sculpting the primordial web into more and more stars… 82 00:09:59,920 --> 00:10:02,000 pulling them toward each other 83 00:10:03,520 --> 00:10:06,280 and spinning them into vast galaxies. 84 00:10:13,800 --> 00:10:14,720 From nothing, 85 00:10:15,680 --> 00:10:19,400 gravity shaped an entire universe of possibility… 86 00:10:22,760 --> 00:10:25,800 that still speckles our night sky. 87 00:10:35,800 --> 00:10:40,480 But light from distant stars won't keep penguin chicks warm. 88 00:10:43,680 --> 00:10:45,280 With their parents at sea, 89 00:10:46,160 --> 00:10:49,120 Rocky and Paloma are losing weight, 90 00:10:50,560 --> 00:10:53,800 becoming more and more vulnerable. 91 00:11:10,400 --> 00:11:12,640 The chicks only refuge from the cold 92 00:11:13,480 --> 00:11:14,840 is their fluffy down 93 00:11:16,520 --> 00:11:17,440 and each other. 94 00:11:19,600 --> 00:11:23,680 Their survival hinges on a precise, elegant dance 95 00:11:23,760 --> 00:11:25,480 between one star 96 00:11:26,320 --> 00:11:27,440 and one planet, 97 00:11:29,320 --> 00:11:34,080 choreographed by gravity over four and a half billion years ago. 98 00:11:43,800 --> 00:11:47,720 Out of the dust and gas left over from the formation of the Sun… 99 00:11:51,240 --> 00:11:54,160 …gravity pulled bits and pieces of rubble together… 100 00:12:01,880 --> 00:12:05,080 …molding them over time into a planet. 101 00:12:15,920 --> 00:12:19,280 It was unrecognizable from the home we know now… 102 00:12:21,720 --> 00:12:24,240 but it had all the potential for life… 103 00:12:28,040 --> 00:12:31,800 bathed in the glow of our newborn Sun. 104 00:12:36,520 --> 00:12:41,400 That same Sun, billions of years later, is now rising… 105 00:12:45,640 --> 00:12:49,080 …signaling to Rocky and Paloma's parents, 106 00:12:49,960 --> 00:12:52,560 it's time to return to South Georgia… 107 00:12:56,960 --> 00:13:01,080 with their bellies full of fish. 108 00:13:08,600 --> 00:13:11,040 As the sun warms the beaches, 109 00:13:11,120 --> 00:13:14,480 the island is transformed into a haven once again. 110 00:13:19,600 --> 00:13:22,880 But making it to shore was the easy part. 111 00:13:25,320 --> 00:13:28,480 Rocky's parents now have to find their baby 112 00:13:29,240 --> 00:13:31,760 amongst thousands of others. 113 00:13:42,600 --> 00:13:47,560 Up the coast, Paloma's parents lock onto her special call… 114 00:13:48,600 --> 00:13:50,720 …and quickly find her in the crowd. 115 00:13:58,240 --> 00:14:01,320 And finally, Rocky's parents also hear 116 00:14:01,840 --> 00:14:03,440 the unmistakable cry… 117 00:14:05,600 --> 00:14:07,080 …of their little one. 118 00:14:13,480 --> 00:14:17,600 His voice has a unique signature only his parents can identify. 119 00:14:21,680 --> 00:14:23,200 It's a family reunion. 120 00:14:25,240 --> 00:14:27,240 And two baby bellies 121 00:14:28,280 --> 00:14:30,200 are full at last. 122 00:14:36,440 --> 00:14:40,160 From the first stars to the birth of our galaxy, 123 00:14:40,240 --> 00:14:42,240 Sun, and planet, 124 00:14:43,480 --> 00:14:46,720 gravity set the stage for life. 125 00:14:53,800 --> 00:14:56,120 But for Earth to become the home we know, 126 00:14:57,840 --> 00:15:01,280 gravity would need to send a bit of chaos our way… 127 00:15:07,320 --> 00:15:10,680 …so evolution could run riot. 128 00:15:20,200 --> 00:15:22,000 Several months have passed. 129 00:15:23,680 --> 00:15:25,800 Rocky's now doubled in size… 130 00:15:28,000 --> 00:15:29,400 and is ready for love. 131 00:15:30,920 --> 00:15:33,680 But he won't truly be an eligible bachelor… 132 00:15:35,720 --> 00:15:39,080 until he's become fit and handsome. 133 00:15:43,320 --> 00:15:45,600 First, a new outfit. 134 00:15:50,680 --> 00:15:53,360 Trading in his childish, fluffy feathers… 135 00:15:55,880 --> 00:15:58,200 for a shiny, waterproof coat… 136 00:16:00,920 --> 00:16:02,880 he's ready for his first swim. 137 00:16:16,160 --> 00:16:17,960 On the other end of the beach, 138 00:16:19,760 --> 00:16:21,800 Paloma is ready to launch as well. 139 00:16:31,560 --> 00:16:34,800 After only knowing dry land their whole lives, 140 00:16:36,080 --> 00:16:38,480 it's an intimidating moment for both. 141 00:16:43,000 --> 00:16:44,840 Rocky thinks he's swimming… 142 00:16:49,000 --> 00:16:51,760 but Paloma actually is. 143 00:17:03,480 --> 00:17:07,480 Rocky finally figures out he needs to be in the water. 144 00:17:12,680 --> 00:17:16,360 These young birds will be gone for the next two years… 145 00:17:18,960 --> 00:17:21,600 on their own separate journeys. 146 00:17:26,560 --> 00:17:29,080 There are great riches awaiting them in the ocean… 147 00:17:32,320 --> 00:17:33,400 thanks to gravity… 148 00:17:36,360 --> 00:17:38,280 …and our nearest neighbor. 149 00:17:49,480 --> 00:17:51,760 Not long after our planet formed… 150 00:17:55,120 --> 00:17:57,640 it collided with another young world. 151 00:18:13,360 --> 00:18:15,200 And out of the orbiting debris… 152 00:18:20,960 --> 00:18:24,320 …gravity formed Earth's traveling companion… 153 00:18:29,000 --> 00:18:29,840 the Moon. 154 00:18:36,680 --> 00:18:40,240 The impact knocked the young Earth onto its side… 155 00:18:41,560 --> 00:18:44,040 -…and threw it into turmoil… 156 00:18:46,040 --> 00:18:48,800 lurching and spinning wildly. 157 00:18:52,280 --> 00:18:54,440 But over billions of years, 158 00:18:54,520 --> 00:18:58,320 the gravitational tug of the Moon tamed the Earth. 159 00:18:59,640 --> 00:19:01,760 The Moon drifted away. 160 00:19:02,920 --> 00:19:05,000 Earth's rotation slowed… 161 00:19:07,400 --> 00:19:10,400 which transformed Earth's story. 162 00:19:15,200 --> 00:19:19,320 Because slower spin meant longer days… 163 00:19:22,000 --> 00:19:26,400 and, therefore, more hours of continuous sunshine 164 00:19:26,480 --> 00:19:28,640 penetrated the oceans… 165 00:19:40,120 --> 00:19:45,400 …creating the conditions for the first life to get a foothold. 166 00:19:52,000 --> 00:19:56,160 The first step in an underwater labyrinth of life 167 00:19:57,000 --> 00:19:59,320 that grew and grew… 168 00:20:05,360 --> 00:20:10,160 …eventually filling the oceans with unimaginable wonders. 169 00:20:24,560 --> 00:20:28,000 Wonders that today provide a rich ecosystem 170 00:20:29,000 --> 00:20:31,520 for two very hungry penguins… 171 00:20:35,120 --> 00:20:37,320 hundreds of kilometers apart 172 00:20:38,000 --> 00:20:39,280 in the open ocean. 173 00:20:44,040 --> 00:20:47,400 Paloma has reached the polar front… 174 00:20:52,240 --> 00:20:56,520 where the Southern Ocean meets the warmer waters of the Atlantic, 175 00:20:56,600 --> 00:20:59,600 Pacific, and Indian Oceans. 176 00:21:04,480 --> 00:21:08,160 Here, nutrients are churned up from below, 177 00:21:09,320 --> 00:21:11,720 supporting thousands of species… 178 00:21:17,000 --> 00:21:22,200 including lantern fish, a favorite of the king penguin. 179 00:21:27,160 --> 00:21:29,040 They live deep underwater. 180 00:21:32,760 --> 00:21:34,760 But that's no problem for Paloma. 181 00:21:36,560 --> 00:21:40,400 She's able to hunt 300 meters below the surface. 182 00:22:02,840 --> 00:22:06,840 Penguins are uniquely adapted to dive and hunt at great depth. 183 00:22:10,160 --> 00:22:14,320 But to understand how these remarkable adaptations came about, 184 00:22:16,280 --> 00:22:21,080 you need to know what gravity had been up to 66 million years ago. 185 00:22:31,680 --> 00:22:35,360 In the cold outer reaches of the solar system, 186 00:22:36,040 --> 00:22:39,360 millions of chunks of ice and rock orbit the Sun. 187 00:22:42,880 --> 00:22:45,680 Most of the time, these asteroids are no trouble. 188 00:22:54,280 --> 00:22:56,800 But sometimes they are. 189 00:23:00,720 --> 00:23:03,560 In the outer region of the asteroid belt, 190 00:23:04,840 --> 00:23:08,600 one particular rock, ten kilometers across, 191 00:23:09,360 --> 00:23:12,680 was warmed by the Sun over millennia. 192 00:23:16,880 --> 00:23:18,160 And bit by bit, 193 00:23:19,040 --> 00:23:25,200 the warming began to shift this asteroid, called Chicxulub, out of its orbit… 194 00:23:28,120 --> 00:23:29,640 until gravity took hold… 195 00:23:32,000 --> 00:23:33,840 pulling it in toward the Sun… 196 00:23:38,040 --> 00:23:41,320 sending it on a collision course with Earth… 197 00:23:48,160 --> 00:23:51,600 …at 72,000 kilometers an hour. 198 00:24:00,520 --> 00:24:04,840 The impact triggered a superheated wave of plasma… 199 00:24:08,360 --> 00:24:12,360 …causing wildfires and devastation across the planet… 200 00:24:15,160 --> 00:24:16,800 blocking out the Sun. 201 00:24:19,520 --> 00:24:23,080 Three-quarters of Earth's species were obliterated. 202 00:24:25,680 --> 00:24:28,200 It was bad news for the dinosaurs… 203 00:24:30,200 --> 00:24:33,840 but good news for the king penguin. 204 00:24:39,840 --> 00:24:41,400 Smaller and lighter, 205 00:24:42,080 --> 00:24:44,720 birds were able to survive the impact. 206 00:24:46,920 --> 00:24:50,280 They took to the skies and diversified. 207 00:24:53,640 --> 00:24:55,640 With large predators gone… 208 00:24:58,360 --> 00:25:01,120 the oceans abounded with fish. 209 00:25:05,200 --> 00:25:09,120 The penguin's ancestors became expert divers, 210 00:25:10,960 --> 00:25:12,240 diving deeper 211 00:25:13,360 --> 00:25:15,160 and staying down longer 212 00:25:16,720 --> 00:25:22,800 until, ultimately, they lost the ability to fly altogether. 213 00:25:28,880 --> 00:25:30,960 From soaring through the skies… 214 00:25:34,880 --> 00:25:37,000 to soaring through the oceans. 215 00:25:42,680 --> 00:25:45,080 Invaluable adaptations 216 00:25:45,160 --> 00:25:48,800 that Rocky and Paloma have put to good use. 217 00:25:53,800 --> 00:25:56,320 Fitter and stronger, 218 00:25:56,400 --> 00:25:59,760 they are now ready to return to their home shores 219 00:25:59,840 --> 00:26:01,080 in search of a mate. 220 00:26:05,200 --> 00:26:07,480 But their homecoming is interrupted… 221 00:26:15,800 --> 00:26:16,720 …by orcas, 222 00:26:18,280 --> 00:26:21,080 the only whale known to eat penguins. 223 00:26:25,160 --> 00:26:27,880 Paloma shifts into top gear. 224 00:26:32,880 --> 00:26:35,400 It will be a race to the finish. 225 00:26:41,040 --> 00:26:42,320 Orcas are fast. 226 00:26:47,920 --> 00:26:50,480 But king penguins are built for speed. 227 00:27:12,800 --> 00:27:15,800 Paloma is too quick for her pursuer. 228 00:27:19,920 --> 00:27:24,280 But Rocky took cover in the kelp forests near the shore. 229 00:27:38,680 --> 00:27:42,200 And the hungry orca isn't going anywhere. 230 00:28:00,080 --> 00:28:01,480 Rocky sees his opening… 231 00:28:06,280 --> 00:28:07,720 and bolts for the shore. 232 00:28:11,200 --> 00:28:14,280 -He definitely knows how to swim now. 233 00:28:20,000 --> 00:28:23,560 Two long years roaming the sea, 234 00:28:24,280 --> 00:28:27,400 all for a chance to enter the great lottery. 235 00:28:29,120 --> 00:28:31,400 The search for love. 236 00:28:34,320 --> 00:28:38,760 Gravity shaped the Sun, Earth, and Moon… 237 00:28:41,400 --> 00:28:44,160 creating a stable home for life on our planet 238 00:28:45,200 --> 00:28:48,480 and steering evolution in new directions. 239 00:28:56,680 --> 00:29:00,680 But the ballad of Rocky and Paloma needs one more part… 240 00:29:03,200 --> 00:29:04,600 …created by gravity 241 00:29:06,240 --> 00:29:08,440 in the fiery heart of the Sun. 242 00:29:12,040 --> 00:29:12,920 Light. 243 00:29:17,240 --> 00:29:19,560 Our star only shines because, 244 00:29:19,640 --> 00:29:23,680 at its center, an intense battle is taking place. 245 00:29:28,040 --> 00:29:29,720 Gravity pulls inward… 246 00:29:31,720 --> 00:29:35,200 while intense pressure pushes back. 247 00:29:41,800 --> 00:29:43,600 This gravitational war…. 248 00:29:48,480 --> 00:29:51,640 …causes atoms to collide and fuse… 249 00:29:58,000 --> 00:30:00,400 …releasing tiny pockets of energy… 250 00:30:02,240 --> 00:30:05,080 …in the form of photons… 251 00:30:12,320 --> 00:30:15,880 …that not only shower the Earth with life-sustaining energy… 252 00:30:18,240 --> 00:30:22,280 but also bathe it in light. 253 00:30:26,920 --> 00:30:29,960 Light that contains its own hidden wonders. 254 00:30:33,000 --> 00:30:35,800 Because within every sunbeam 255 00:30:36,920 --> 00:30:38,040 is a rainbow. 256 00:30:41,400 --> 00:30:44,160 Each photon has a unique wavelength 257 00:30:45,440 --> 00:30:48,600 and interacts with the stuff our world is made of 258 00:30:49,120 --> 00:30:50,320 in a different way. 259 00:31:01,880 --> 00:31:04,640 Some wavelengths are absorbed. 260 00:31:06,160 --> 00:31:08,680 Others are reflected. 261 00:31:12,760 --> 00:31:18,000 How these light waves hit our eyes determines what colors we see. 262 00:31:22,400 --> 00:31:24,840 And this ability to perceive color 263 00:31:25,680 --> 00:31:29,680 plays a key role in the penguin dating game. 264 00:31:39,200 --> 00:31:43,480 Years of feasting at sea have made Rocky fit and strong. 265 00:31:48,120 --> 00:31:51,400 Traits he needs to display to attract a mate. 266 00:31:58,200 --> 00:32:01,200 Pigments that he synthesized himself 267 00:32:02,360 --> 00:32:04,800 color his feathers brilliant yellow… 268 00:32:07,000 --> 00:32:09,480 perfect for showing off his own flair 269 00:32:11,360 --> 00:32:16,800 and attracting the gaze of the one bird in this crowd… 270 00:32:22,000 --> 00:32:25,600 -…who only has eyes for him. 271 00:32:29,800 --> 00:32:30,640 Paloma. 272 00:32:44,520 --> 00:32:48,680 Starlight reflects onto the retina at the back of Paloma's eye. 273 00:32:55,000 --> 00:32:58,280 Here, millions of cone cells get to work 274 00:32:58,360 --> 00:33:00,480 decoding every wavelength… 275 00:33:07,000 --> 00:33:12,200 …which allows Paloma to distinguish one color from another. 276 00:33:16,480 --> 00:33:17,840 In the blink of an eye, 277 00:33:18,360 --> 00:33:22,600 these lovebirds are not only able to see their world 278 00:33:23,640 --> 00:33:26,280 but also understand it 279 00:33:27,800 --> 00:33:30,280 and find their soulmate. 280 00:33:36,840 --> 00:33:40,840 The courting then turns to a carefully choreographed dance. 281 00:33:43,680 --> 00:33:46,480 Each displaying their dazzling, yellow feathers… 282 00:33:50,920 --> 00:33:52,280 for the other to admire. 283 00:34:03,600 --> 00:34:05,600 Other suitors try their luck 284 00:34:05,680 --> 00:34:07,000 but to no avail. 285 00:34:12,600 --> 00:34:14,360 Because Rocky's yellow feathers… 286 00:34:16,560 --> 00:34:18,360 aren't his only selling point. 287 00:34:22,240 --> 00:34:23,520 By shaking his head… 288 00:34:26,280 --> 00:34:28,280 he encodes a secret message… 289 00:34:30,680 --> 00:34:32,680 in ultraviolet light. 290 00:34:35,120 --> 00:34:37,240 His beak catches the Sun 291 00:34:39,000 --> 00:34:40,720 and reflects its rays. 292 00:34:47,200 --> 00:34:49,360 And thanks to an extra cone cell… 293 00:34:51,760 --> 00:34:56,640 …Rocky and Paloma's eyes can see colors beyond our own. 294 00:34:58,240 --> 00:35:02,120 These UV signals win Paloma over. 295 00:35:04,040 --> 00:35:05,880 They're the perfect match. 296 00:35:12,840 --> 00:35:16,000 Raising a penguin chick is a grueling task 297 00:35:17,880 --> 00:35:21,480 that requires both parents to be in top form. 298 00:35:26,320 --> 00:35:29,760 Impressive yellow feathers and a flashy beak 299 00:35:29,840 --> 00:35:32,800 are proof of strength and ability, 300 00:35:34,320 --> 00:35:38,040 essential characteristics when it comes to bringing up a family. 301 00:35:41,360 --> 00:35:44,120 From all the thousands of other birds, 302 00:35:45,000 --> 00:35:46,840 Rocky and Paloma… 303 00:35:49,640 --> 00:35:51,280 have found each other. 304 00:36:00,880 --> 00:36:03,480 From the first ripples in the cosmic web… 305 00:36:09,560 --> 00:36:11,240 …to the birth of our Sun… 306 00:36:13,680 --> 00:36:14,560 planet, 307 00:36:15,840 --> 00:36:16,720 and Moon… 308 00:36:21,680 --> 00:36:25,000 …the impacts that have written Earth's history… 309 00:36:27,800 --> 00:36:33,160 …to the force that powers the Sun, painting our world in color… 310 00:36:35,280 --> 00:36:40,280 gravity has had a hand in all of it… 311 00:36:44,200 --> 00:36:48,200 guiding these two penguins to their special moment… 312 00:36:51,920 --> 00:36:54,080 …on this special island… 313 00:36:58,240 --> 00:37:02,120 where it's not long before something extra special 314 00:37:02,200 --> 00:37:03,640 is delivered to Earth. 315 00:37:04,800 --> 00:37:09,760 Rocky and Paloma are going to be parents themselves. 316 00:37:13,680 --> 00:37:15,440 Ushering in a new life 317 00:37:16,160 --> 00:37:19,080 and maybe even new romance… 318 00:37:21,880 --> 00:37:25,720 with gravity, as ever, helping to lead the way. 319 00:37:33,880 --> 00:37:35,440 All across the Earth, 320 00:37:36,440 --> 00:37:38,880 life is dazzling in its variety. 321 00:38:04,520 --> 00:38:07,520 It has taken 13.8 billion years 322 00:38:07,600 --> 00:38:10,880 to reach this one precious moment 323 00:38:10,960 --> 00:38:13,680 in time and space. 324 00:38:22,520 --> 00:38:25,720 Every animal made from the stars… 325 00:38:27,720 --> 00:38:29,800 synchronized with the planet, 326 00:38:31,440 --> 00:38:34,720 and sustained by gifts from the cosmos 327 00:38:34,800 --> 00:38:38,400 that only made it here by pure chance. 328 00:38:52,320 --> 00:38:53,920 All held in its place 329 00:38:54,000 --> 00:38:55,120 by the ultimate, 330 00:38:56,040 --> 00:38:58,960 the original force of attraction. 331 00:39:07,320 --> 00:39:09,520 The story of our universe 332 00:39:09,600 --> 00:39:14,440 is the story of how life came to be here on this planet… 333 00:39:17,880 --> 00:39:19,400 …we call home. 334 00:39:23,080 --> 00:39:27,120 A story that is still being written.
