QFT interpretation of Hawking Radiation

Click For Summary
Hawking radiation is explained through quantum field theory (QFT) as a process involving virtual particles in a vacuum that typically cancel each other out. In the presence of a black hole, this balance is disturbed, allowing virtual particles to become real particles that appear to emerge from the black hole. The discussion raises a question about how a black hole can disturb these waves without simply absorbing them. The complexity of this phenomenon suggests that a straightforward answer may not exist. Understanding this concept requires a deeper exploration of quantum mechanics and the nature of black holes.

Hello,

So I was reading about Hawking radiation and I read a QFT interpretation of it. It went something like this:

A vacuum contains virtual particles (vacuum energy), which in qft can be described as waves that are out of phase and cancel each other out (matter and antimatter). I a black hole, this out-of-phase state is disturbed and the waves do not cancel each other out, thereby converting virtual particles into particles that seem to originate from the Black Hole.

My question is, how does a Black Hole merely "disturb" the waves of the field and not simply suck them in? I mean, isn't that what Black Holes do? Here is an image of what I'm talking about from a video by PBS Space Time:

(I'm 15 by the way, so please tell me if there are flaws in my explanation)

Reading where? You will get much better answers if we know what you've been reading.

There may not be any simple answer to your question. You can find Hawking's paper here and there is a somewhat more friendly explanation here.

I am slowly going through the book 'What Is a Quantum Field Theory?' by Michel Talagrand. I came across the following quote: One does not" prove” the basic principles of Quantum Mechanics. The ultimate test for a model is the agreement of its predictions with experiments. Although it may seem trite, it does fit in with my modelling view of QM. The more I think about it, the more I believe it could be saying something quite profound. For example, precisely what is the justification of...
