You know, back in 1970, there was a graduate student at Princeton called Jacob Bekenstein. And he read papers written by Stephen Hawking, who said he demonstrated, Stephen Hawking demonstrated that when you take two black holes, the area surrounding the black holes, a black hole is an ultimate prison. Nothing can escape from it. It's just like Vegas. Anything that happens stays in it. But when you merge two black holes, the area surrounding them, the product of the merger, is always bigger than the sum of the areas. He demonstrated that mathematically. And then Bekenstein said, well, that's interesting because we know about the second law of thermodynamics where entropy always increases. So maybe the black holes have entropy related to their surface. And his mentor was John Wheeler at Princeton. And he said, you know, this is a crazy enough idea that it might be true. Speaking about nutty ideas. And then Stephen Hawking heard Bekenstein speak about it. And he said, that's nonsense. That's nonsense, makes no sense. I will prove it to be wrong. So he used quantum mechanics in a curved space-time around a black hole. And lo and behold, he found they emit radiation. They have a temperature. They have entropy. This is the biggest discovery, theoretical discovery of Stephen Hawking, celebrated since, you know, for 51 years now. And he went to disprove Bekenstein and proved him right. It was considered a crazy idea in the mind of the person who benefited most from discovering that Bekenstein was right.
