Can somebody please explain the maths (and physics) of black holes evaporating (in simple terms)

Black holes (through a variety of possible methods, I can't remember which one's in vogue) emit subatomic particles. Obviously, this is a loss of mass, so they gradually get smaller.

What subatomic particles; bosons, positrons? and why dont these particles fall into the holes itself

Uhm excuse me I might sound stupid but aren't black holes supposed to have such a huge gravity that NOTHING "escapes" their 'grab' ?

 

What's the basis of this theory?

i dont see why they would collapse considering that emissions from a blackhole are composed of roughly 10% of the mass taken in. Emitted as radiation thats detectable... im puzzled why they would lose their integrity under the hypothesis that blackholes can almost expand endlessly. im very interested in this subject ! if anyone has concrete data concerinng it please post!

its all theoretical but what jakiri posted is what current understanding tells us

I Googled "Hawking radiation" and found a couple of sites that might answer the question:

http://casa.colorado.edu/~ajsh/hawk.html

oh, so taking into consideration that if nothing enters their event horizon to 'feed' the singularity, then it will eventually spiral down to nothing.

Is there a point were a black hole becomes so big that these particles etc cannot escsape

 

 

 

BTW i want the name black hole disposed and a new name in its place

I think the term black hole came because of the term

black body radiation(BBR).

What would you like to call it? vacuum sucker?

It was a term coined in the earlier part of last century by John Wheeler.
