How Do Gravitons Leave Black Holes?

[Rev. Green]

How does a black hole attract matter if nothing, except a small amount of Hawking radiation, can escape?

[ToraToraTora]

they don't, they are a theoretical Boson anyway.

I'd have to think about this because it's not something I routinely study.

Let me get back to you.

[jim360]

I mean this in the nicest way possible, spath, but please don't try and answer this question.

[ToraToraTora]

TBF spath didn't try and answer the question, he answered something of his own choosing!

[jim360]

Your first answer had nothing to do with the question asked. Neither does the second one, if it comes to that.

[ToraToraTora]

spath: your answer is a poor description of a gravity field, not what is being asked. It also assumes that all stars have less mass than all black holes so it's nonsense too.

[Old_Geezer]

Perhaps there isn't such a thing as a graviton after all ?
Interesting question though.

[Old_Geezer]

Alternatively, I guess, they could come into existence just outside the event horizon ?

[ToraToraTora]

not with you jim. A black hole formed by a star would need to be a star of at least 25 solar masses, so there must be some smaller than the many stars that are greater than 25 solar masses.

[Old_Geezer]

They don't all spin; or do they ? I thought rotating ones were just one type but maybe they all do eventually. I know less of this than I thought, or senility has robbed me of the info.
