Abstract:
Present treatments of eternal inflation regulate infinities
by imposing a geometric cutoff.
We point out that some matter systems
reach the cutoff in finite time.
This implies
a nonzero probability
for a novel type of catastrophe.
According to the most successful measure proposals,
our galaxy
is likely to encounter the cutoff
within the next 5 billion years.
