Hawking radiation

What is an anti particle? What happens when a particle meets an antiparticle? Do they disappear without trace? Or do they explode, leaving some kind of matter? I still don't think matter can be negative. Help!!!

I don't understand. It is said that the mass of a blackhole decreases. As matter gets sucked inside a black hole, its mass should increase, and therefore, its event horizon should increase too, shouldn't it? as for negative mass, how can mass be negative? It is a scalar quantity.

Nice theory, sounds good.

Not that I don't believe this, but there is a lack of evidence to support this. Hawking essentially makes up a theory to explain something which is not based on observation... which is not science. That is philosophy. And Hawking radiation is based on the theory that particles come in and out of existence. Again there is no direct proof of that. Hawking has a vivid imagination and he might be right on this one. But move evidence is needed to prove this.

You make it sound like he's sitting around playing xbox smoking pot, then pauses the game and says Eureka!!
That is not the case.

Try and understand for a second the intense mathematical proofs that go into coming up with a theory like this.

People said the same thing about the existence of black holes themselves until tech caught up with theory and they could be observed to a small extent, yet now you talk about black holes as a matter of fact.

the black hole evaporation?.

I am a proffesor at FU.

what documentary is this from?

The documentary is called "Stephen Hawking: Master of the Universe"

BBC Horizon I think, about a year ago now...
