All existing science suggests there can never be a big crunch, that concept predates observations of the universe acceleratingnits expansion, when people thought gravity must be slowing the expansion and thus could stop and reverse it at some point in the future.
There are no past universes and there's nothing to suggest there will ever be another. This is it, we exist in the very early part of the warm universe and there's only so much time ahead of us before everything not local dissapears over the horizon and everything that's left goes cold and dead for all of eternity, the universe doesn't operate on terms that are friendly to your concepts of right and wrong.
