Query: Is Our Universe Likely to Decay within 20 Billion Years?   Observations that we are highly unlikely to be vacuum fluctuations suggest
that our universe is decaying at a rate faster than the asymptotic volume
growth rate, in order that there not be too many observers produced by vacuum
fluctuations to make our observations highly atypical. An asymptotic linear
e-folding time of roughly 16 Gyr (deduced from current measurements of cosmic
acceleration) would then imply that our universe is more likely than not to
decay within a time that is less than 19 Gyr in the future.
