Read something that is bothering me (in Aug 82 Sky and Telescope).
According to the article a black hole with the mass of our universe
will "evaporate" (I think that's the right word) in 1.7 * 10**135 years.

Does this explain the possible singularity of the big bang. I.e. if the
universe is collapsing will the big bang cycle take place approx. every
10**135 years.

Is it reasonable to ask where the particles escaping the universal black
hole are going?

The article "Opinautics: a matter of much gravity" is one of these strange
articles discussing anti future universes - I'm intrigued but can't claim
to truely follow the concepts.
