Creepy story about a man who volunteers to rescue people from a
wormhole that randomly appears in cities, killing anyone who is not
able to make it to the center of the spacetimedistortion before it
disappears. The mathematical content of the story is only in the
discussion of the probabilistic aspect of determining when it will
disappear. Like nuclear decay, the probability is constant; at any moment
the probability that the wormhole will disappear is the same as at any
other moment. The character discusses the implications of such a
probability distribution as well as specifically addressing some of the
misconceptions people might have about it. Contributed by
