Are Black Holes Hot? A Deeper Look

[Cbray]

I was wondering if black holes are insanely hot, my guess is they are because so much matter has been crushed together causing friction and energy.
Is this right? Thanks.

PS: if it's something a 14 year old wouldn't understand, please give me a url link to wikipedia where I can study it, thanks, bye!

they r not hot bcs they have huge gravitation and they can also change the hit to the mass energy

This happens to material the approaches the event horizon of a black hole.

So no one actually knows what happens to the matter once it goes inside the black hole?

I don't know but I'm just giving my amateurish thought on the subject.

I don't think there is an answer to your question because, as you suspect, we don't know.

If heat is movement of molecules, I don't see how they could move at all in a black hole if they were so tightly held together by gravity. Could that mean that black holes are precisely 0K ? I don't know...and not sure if anyone does.

Beyond the event horizon all bets are off for determining what is really going on. Contemporary understanding is that beyond an event horizon is a gravitational singularity, this is a point of infinite density. Notions like heat don't really apply.

Outside the black hole an accretion disc can form, this is a spinning disk of matter that is spiralling into the black hole. All that matter smashing together is likely to cause a lot of heat.
