White holes

  1. Aug 22, 2010 #1
    Does the theory allow White Holes to exist?
    I read "somebody" thinks that black holes are connection to other universes; as b.o. continuously capture materials... couldn't they be emitting this material in the other universe? Could they be "white holes"... or, in other words, "big bangs"?

    This theory was explored fairly comprehensively in 'Red Dwarf'

    It seems unlikely, and white holes were really just tossed around as a possible example for Quasars, which we now understand to be Active Galactic Nuclei.

    there is no scientific proof of white hole, and it has been proven that black holes do release a bit if energy in the form of heat, about a nano degree above absolute zero, so energy that is absorbed in a black hole doese return to our universe, also by the laws of concervation then it is impossiable for a universe to loose energy but to only convert it into other forms
    but the idea of white holes arre interesting :)

    Unknown. If you use standard GR, it turns out to be hard to make a white hole, but no one knows if they exist or not. Once you go into quantum gravity, we don't have "the theory".

    Lee Smolin came up with this idea already :-) :-)
