Black Hole Evaporation

  1. Feb 25, 2008 #1
    If it is indeed true that black holes (eventually) evaporate, then once they lose enough mass do they then return to become a normal body of matter?

    I would assume that once this happens there would be an enormous explosion due to constraints of relativity disappearing.

    For black holes of any significant size, the evaporation rate is rxtremely slow. The stuff coming off would be normal matter, but the black hole itself just keeps getting smaller, but still a black hole, until it disappears.

    This is just like that other thread! :)

    As a black hole evaporates it gets hotter and hotter and radiates more and more until at roughly the planck size it just evaporates away (hence the name of the process) into a shower of high energy photons and other particles.
