QFT interpretation of Hawking Radiation

Click For Summary
SUMMARY

The discussion centers on the Quantum Field Theory (QFT) interpretation of Hawking radiation, specifically how black holes disturb the vacuum state of virtual particles. It explains that in a vacuum, virtual particles exist as waves that cancel each other out, but when a black hole forms, this balance is disrupted, allowing virtual particles to become real particles emitted from the black hole. The conversation highlights the complexity of this phenomenon and encourages further exploration of Hawking's original paper and related insights on virtual particles.

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.
