" Don't most astrophysicists now predict some " end of the line" - an end to it all? Not just the death of things, but the annihilation of everything. Some great contraction, or collapse. Or, perhaps, some vast dissipation into eternal emptiness. Maybe it's all swallowed up by an immense black hole, which then swallows itself. But, whatever the case, their extinction is inevitable and absolute. So complete as to erase any and all evidence that this reality - this existence - ever took place. So complete that, perhaps, for all intents and purposes, it never really did. (attrib: F.L. Vanderson) "
