In my previous article I referred to John Ellis when I meant
George Ellis.  People should strive for more distinctive names :-).

Also, the repeating universe idea does not explain the large scale
statistical homogeneity of the universe (the flatness problem)
unless the cycle distance is *very* short.  How short depends on
what you think a "natural" initial state might be.  If one assumes
total chaos then a few billion Planck lengths might be OK.
(About 10^-34 cm).  If one assumes more irregular, but not
totally chaotic conditions then perhaps sub-galactic scales could
be used.  Obviously since we know the cycle distance must be greater
than a few hundred mpc this isn't a promising way to solve the flatness
problem.  Which doesn't mean it couldn't be true on some large scale.
