There is Poincare recurrence, where for N distinct quantum states or units
of phase space volume occupied the recurrence time is on the order of T =
10^Ndt, for dt the increment of time fundamental to state changes. This
might mean dt is the Planck unit of time 10^{-43}sec This is then a huge
time if one considers the observable universe with 10^{80} particles, and
so this time is 10^{10^{80}}dt. But this is not all, for we may have to
consider quantum recurrence time that would be 10^T or 10^{10^{10^{80}}}dt,
which curiously is the lower bound on the stability of the de Sitter
vacuum.
To make things a bit more bizarre, if space is flat and infinite R^3 then
there will be regions out there with duplicates of you. With the
equivalence of space and time the closest should be around 10^{10^{80}}dx
for dx the elementary unit of distance most identified as the Planck length
10^{-33}cm. So duplicates of this local world and ourselves may not just be
a recurrence in time, but in space as well.
