Have a read through the answers to An explanation of Hawking Radiation to get a better idea of what Hawking radiation is. The popular explanation of virtual particles falling into the black hole is just a metaphor and should not be taken literally. The proper explanation for Hawking radiation is I'm afraid far more complicated than that. A black hole does ...

Why not negative energy? Energy is a scalar quantity that is conserved. Negative energy means that there exists a potential well which for bound quantum mechanical states has negative energy, and for free states positive. A matter of definition. Look at the hydrogen atom states Note the - sign for the energy levels In the case of the black hole the ...

First of all, let me point out that the supertraslation proposal to solve the paradox is not due to Hawking. Is due to Hawking, Perry and Strominger and is based on previous works of Strominger and collaborators. Unfortunately this habit of giving too much merit to very well know people is very common, especially from mass media. The supertraslation ...

Hawking radiation is a theoretical result from the analysis of quantum field theory in general relativistic, curved spacetime. This sort of semi-classical analysis, combining aspects quantum mechanics of with classical GR, is a stepping stone to a full theory of quantum gravity. The theoretical result does not prove that Hawking radiation exists. If ...

I will first show a simple way to think of Hawking radiation and how we might indirectly observe it. If you have a particle on an accelerated frame it is within what is called a Rindler wedge. Below is a diagram of spacetime for an accelerated frame. We think of a particle in region I The hyperbolic lines are regions of constant radius from the $45$ degree ...
