Could universe be a blackhole inside a white hole?

  1. Mar 5, 2014 #1
    Would it be possible for the universe to exist as a white hole within a black hole? I know about the whole black hole universe theory, though I never really looked into it.

    I think the title of this thread might be the wrong way round.

    Try this:

    They suggest that a white hole might be like the Big Bang. Is this like what you meant?

    I know of no proposed theories or models which even suggest this is possible.

    Poplowskii has such a model or did at one time, it involved torsion and spin to attempt to account for the cosmological constant and the homogeneous and isotropic nature of the universe. No idea if he still follows or continues the model. If I recall the model failed to account for early universe large scale structure formation.

    That, and there is no such thing as a "black hole inside a white hole".

    I think the title's wrong. He means a white hole inside a black hole.

    Yeah. No such thing as that either.:rolleyes:

    Could you explain a bit more in the context of Fecund Universes?

    Are you saying that Fecund Universes isn't a viable theory, that white holes don't exist, or the two are incompatible?

    I'm saying that there is no solution in Einstein gravity that describes a white hole inside a black hole. I'm not familiar with "Fecund" universes -- can you provide a reference?

    If what you're saying is correct then are we to presume that Smolin's theory precludes white holes?

    Is there even a solution to Einstein gravity that could he could use?

    Thanks for the reference. I don't see any mention though of white holes as part of the "fecund universe" construction...
