An upper limit to the size of black holes?

  1. Jul 1, 2011 #1
    In an earlier post I make the controversial suggestion that the universe was very heterogeneous in the early stages. I have another conjecture that goes along with that one.

    Please try to read this with a bit of an open mind.

    Imagine that there is an upper limit to the size of a black hole. Presume that the supermassive black hole in a galaxy eventually consumed most or all of the matter in the galaxy. Think of what might happen when a couple million of these super massive black holes combine. Might there be a point where the conditions inside the black hole are so extreme that matter cannot exist in any form?

    If a black hole reached that state, what would happen? If the matter simply cannot exist, then what does it do?

    One possibility might be that it would translate into energy. Over some relatively small amount of time, all, or maybe most of the matter energy in this black hole would translate into energy. Now there is no longer any matter to bend space. What once was a black hole is now a huge amount of energy in a relatively very small space. Effectively a big bang.

    Back to my earlier post: If that black hole did not contain “all” the matter of the universe, then the matter around it would disturb any homogeneity of the explosion. Maybe the explosion would cause some, most, or some number of the nearby black holes to burst or rupture suddenly releasing their matter.

    Before shooting me down, take a minute to play around with this concept. Think of it as a fun exercise and see what you might come up with.

    In any black hole, conditions are so extreme that matter cannot exist in any form. That's what the singularity is.
