: : Do black holes ever cease to exist?

: It is believed so.

: Stephen Hawking promotes this theory called, : "Hawking radiation",that eventually extinguishes : the black hole.

: His reasoning is this:

: Take a empty can for example, imagine you have a : many particles with each having X amount of : energy. Imagine that in order for one of those : particles to 'escape' the opening of the can it : is needed to have 2X of energy. How does a particle : escape?

: Well the analogy has been given as imagining a bunch : of frogs in a bucket, not one frog is capable of : jumping over the edge, but perhaps it is possible : if one frog is sitting on another and the instant : the one frog jumps (on bottom) the other frog jumps : as well at the crest of the first frogs jump. Well, : in theory the frog on top will escape. Thus extinguishing : the BH in a finite amount of time.

: This theory goes for the particles that are 'beyond' : the event horizon of the BH. (if that is even imaginable)

: I personally have problems with some of the intracacies : within the theory, but can see it in operation outside : of the EH, not beyond it.

do you think that there is a critca mass were the black hole could no longer hold its infinate density and would rapidly expand and blow up?

do you think it would cause a strobing affect Language Removed star shot off extra mass it coulnt hold and reformed into a black hole?
