1 00:00:00,000 --> 00:00:02,002 [Music throughout] 2 00:00:02,302 --> 00:00:06,740 Have you ever wondered what it would look like to fly into a black hole? 3 00:01:07,033 --> 00:01:11,037 So, what is happening here? 4 00:01:11,104 --> 00:01:18,545 This is a simulation of a flight into a supermassive black hole surrounded by a hot, glowing disk of gas. 5 00:01:18,545 --> 00:01:25,985 The thin inner circle is called the photon ring. It’s an image produced by light that has orbited the black hole one or more times before escaping. 6 00:01:27,720 --> 00:01:32,459 This oval, centered on the camera’s direction of travel, shows the entire simulated sky. 7 00:01:34,461 --> 00:01:38,264 Camera position and orientation relative to the black hole. 8 00:01:38,264 --> 00:01:42,068 For the camera, time slows compared to that of a faraway observer. 9 00:01:42,469 --> 00:01:48,508 The camera is aiming at the photon ring’s far side. It’s now moving so fast that the simulation slows for a better view. 10 00:01:50,944 --> 00:01:56,282 The camera’s speed causes light sources directly ahead to brighten greatly. 11 00:01:57,484 --> 00:02:03,423 The camera begins its 10-minute plunge to the event horizon. 12 00:02:06,993 --> 00:02:09,829 The camera hits the event horizon ... 13 00:02:09,829 --> 00:02:11,998 now. 14 00:02:12,365 --> 00:02:17,470 Light from the outside universe still shines in, but can never leave. 15 00:02:19,305 --> 00:02:24,410 The camera is destroyed. Microseconds later, it reaches the singularity. 16 00:02:25,478 --> 00:02:30,783 A closer view shows just how layered and intricate the photon ring is. 17 00:02:45,131 --> 00:02:50,436 Each band is a distorted image of the gas disk layered between the background sky. 18 00:02:50,837 --> 00:02:56,142 Successive bands are thinner, produced by photons that have taken an additional trip around the black hole before reaching the camera. 19 00:03:06,352 --> 00:03:14,294 Due to the camera’s speed, the entire sky appears to shift progressively forward. The sky is shrinking before our eyes. 20 00:03:25,538 --> 00:03:30,843 On a typical laptop, computing this simulation would have taken more than a decade. 21 00:03:30,910 --> 00:03:37,684 The Discover supercomputer at NASA’s Goddard Space Flight Center performed the feat in 5 days ... 22 00:03:37,684 --> 00:03:41,988 ... using only 0.3 percent of its processing power. 23 00:04:15,021 --> 00:04:19,325 NASA
