It is very interesting that essentially there are causally disconnected subsets of the universe - each a sub universe onto their own. Although globally not possible, is the gravitational collapse scenario plausible for some of these causally disconnected subsets? Tying it with the fact that galaxies seem to be slowly eaten by their black hole centers, would this be an example of a local gravitational collapse?
And when this process is over, what happens to all the black holes, isolated from everything else.. do they just dissipate out, creating a uniform, cold, low entropy universe?
- bkeroack 12y agoIt would be a uniform, cold, high entropy universe. The highest entropy possible. Once all the black holes had eaten through all matter and subsequently all radiated away (via Hawking radiation).
- bronson 12y agoCorrect. As we understand it now, the black holes will slowly evaporate through Hawking radiation. http://en.wikipedia.org/wiki/Future_of_an_expanding_universe#Black_Hole_Era http://en.wikipedia.org/wiki/Future_of_an_expanding_universe...
