: Assuming the universe does NOT collapse under gravity

: When all the stars burn out-everything left will be light/heat.

: However blackholes will still exist -could they allow a rebirth?? ie fresh matter for new stars etc etc Anything is possible, especially since, until gen. rel. is made compatible with quantum theory, the ultimate fate of black holes is open. Furthermore, there is a paradox in black hole theory as it stands. To the outside universe, black holes take foreover to form, so it is not clear what the ultimate fate of a black hole is even without the quantum compatibility question. : Zeon
