Timewave Zero.
Think about it.
It would be AWESOME.
Time and space would coalesce into a singular point, wherein everything and anything would happen all at once; you would meet yourself and the universe would be made and destroyed at the same time, everything woul cancel out and all that would be left would be a giant, bollock naked, grinning Rick Astley floating in a grey anti-universe, with a continuously looping Rickroll shining in his hollow eye sockets.
THERE. That's enough to get the eschaton started!
Bring on the Astley!
Either that, or a misanthrope comes up with the Anti-Life Equation and uses it on God.
