Do Black Holes emit Hawking radiation while engulfing normal mass?

Question

As I read on various sites ,all of them say that Black Holes emit Hawking radiation as one of the instantly created virtual particles near Event Horizon escapes from it.One goes inside it and other particle escapes and this particle(which escapes) constitutes Hawking radiation. So while engulfing Normal BODIES,does it emit something,so that the information preserves somehow?

Answer 1

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 not necessarily emit anything when an object falls into it. If the falling object has a non-zero angular momentum there will be gravitational waves emitted, but these are unrelated to the information paradox.

At the moment there is no widely accepted explanation for the information paradox. There are many suggestions including a recent one from Hawking himself, but none of them are sufficiently convincing to have become widely accepted.
