Ah, but its the clock speed that matters. Upgrading to successively
faster pocket universe after pocket universe (each nested within the
previous) would allow umpteen magnitudes more quantitative run time,
ergo more 'life'. What does it matter if the U-prime universe is going
to phase out in 100 billion years when one second there is equal to 10^n
seconds in Pocket Universe Level n?

Recall Egan's 'Diaspora' - the perpetual voyage to ever higher
universes, all with similar constraints cosmologically, but each higher
level universe runs faster.
