Zeitbeben.

On February 13th, 2001, according to Vonnegut, the universe will tire momentarily of expanding forever. What's the point? Maybe it would be more fun to shrink for a change, and have a reunion of all the stuff back where it began. Then it could make a great big BANG again.

It will shrink back to February 17th, 1991, but will then decide that expansion is the way to go, after all. As time marches on once more to 2001, though, Vonnegut and Trout and everybody else and everything else will have to do exactly what they did the first time through the decade, for good or ill: marry the wrong person, bet on the wrong horse. Whatever! Ten years of deja vu all over again! At least deja vu doesn't cause physical injury and property damage.
