What evidence is there that Rosen's models describe reality better than
the usual ones?
And where does Tipler rely on modelling complex systems as Markov
processes? His main arguments about the Eternal Return and the Bekenstein
Bound applies to just about any system; even if the system does it best
to be unpredictable or organized it *has to* repeat itself in a finite
time if it is finite and non-growing. Markov processes are awfully general.

What is the evidence that vacuum is not a state of near maximal entropy?
(One vacuum with virtual particles looks like any other vacuum -> *very*
high entropy)
