Right.

Right.

Exactly. So, of course, Oppenheimer, now known as the father of the atomic bomb, he talks about destroyers of worlds. But it's the same technology. And that's what I mean by science is agnostic, right? It's the same technology, overcoming a critical mass, igniting thermonuclear fusion. Eventually, there was a fission. The original bomb was a fission bomb.

And fission was first shown by Lise Meitner, who showed that a certain uranium, when you bombarded it with protons, broke into smaller pieces that were less than the uranium, right? So some of that mass that E equals MC squared energy had escaped. And it was the first kind of concrete demonstration of this, Einstein's most famous equation.

So all of this comes together, but the story of, they still weren't called black holes. This is 1939. And they had these very long-winded ways of describing the end state, the catastrophic end state of gravitational collapse. But what you have to imagine is as this star collapses, so now, so what's the sun? The sun's a million and a half kilometers across.

So imagine a star much bigger than the sun, much bigger radius. And it's so heavy, it collapses, it supernovas. What's left is still maybe 10 times the mass of the sun, just what's left in that core. And it continues to collapse. And when that reaches about 60 kilometers across, Like, just imagine, 10 times the mass of the sun, city-sized. That is a really dense object.

And now the black hole essentially has begun to form, meaning the curve in spacetime is so tremendous that not even light can escape. The event horizon forms, but the event horizon is almost imprinted on the spacetime because the star can't sit there in that dense state any more than it can race outward at the speed of light. Because even light is forced to rain inwards.

So the star continues to fall. And that's the magic part. The star leaves the event horizon behind. And it continues to fall. And it falls into the interior of the black hole. Where it goes, nobody really knows. But it's gone from sight. It goes dark. There's this quote by John Wheeler, who's like granddaddy of American relativity, and he has a line that's something to the effect.
