Black Hole Apocalypse

00:00:03 JANNA LEVIN: Of all the objects in the cosmos

00:04:41 Right here, in these facilities,

00:09:56 We don't have the physics to describe them

00:14:59 Ever since he was a teenager, he had been calculating

00:19:54 after it finishes burning its hydrogen fuel

00:24:40 with some advanced technology for interstellar travel,

00:30:12 what's happening inside there?

00:34:58 So Murdin begins searching for a visible star

00:39:42 became stronger and stronger and stronger

00:44:17 and we synthesize in a computer

00:49:07 fire-eating demons, if you will

00:54:17 LEVIN: There's no way a quasar could be a star

00:59:23 at the bottom of a river

01:03:46 LEVIN: The key to finding supermassive black holes

01:08:16 it would have consumed

01:13:11 How is it possible to make such gigantic black holes?

01:18:20 It won't show up on any telescope

01:22:54 So photons can impart a force on something

01:27:38 We've come in a very short time to realize

01:32:16 to take a picture of a black hole

01:36:23 LEVIN: As a physics problem,

01:40:44 was extremely controversial

01:45:44 THORNE: So what we saw in the signal

01:51:01 and challenge both our science and our imaginations
