Joseph,
Thank you for your comments about the Penrose book. We discussed this briefly
before, but, if you haven't already read Jacob Bekenstein's work on black hole
thermodynamics and the holographic principle, you should. Much of it is related
to the material you describe for the Penrose book. I'm still working on the
Kaluza-Klein Biology paper that I mentioned to you. I hope to soon finish it.
When its ready for circulation, I'll send you a copy.
Best regards,
Kevin

Dear Pedro, Dear FISers,
In our search for the "foundations of information" two years ago, we looked at
Michael Conrad's fluctuon model of the universe. We came to the conclusion, I
think, that 1) any coupling of fluctuations in the quantum vacuum to
thermodynamic entities (biological macromolecules) has not been confirmed and
2) the concept of information as energy does not apply to the "timeless"
vacuum background.
Roger Penrose's 2011 book, Cycles of Time, which I have just read, presents a
new view of the universe as described by a conformal cyclic cosmology (CCC). It
makes some remarkable statements about information which I believe are worth
discussion. His key point is to make information loss in black holes the
condition for the reduction in the phase-space volume of the universe to
permit geometrical matching between a De Sitter "end" of one universe or aeon
and the smooth transition to an Einsteinian Big Bang in a new aeon, both
involving massless particles. Penrose thus goes back to Hawking's original
theory, as he finds it difficult to see how any real structural information can
be maintained outside the black hole by the photons leaking through.
Deterministic unitary "Schroedinger" evolution must be accompanied by
probabilistic processes, as is also clear from Lupasco. Also clear is that as
matter evaporates, the associated space (and time) collapses
to the necessary conformity for which Penrose gives good mathematics, without
violation of the 2nd Law as in other cyclic models. Mass reappears in the new
aeon under the influence of something like a Higgs field.
The other remarkable statement is in the text of Fig. 3.1, page 142, which
reads as follows: "Photons and other (effectively) massless particles/fields
can propagate smoothly from an earlier pre-Big Bang phase into the current
post-Big Bang phase or, conversely, we can propagate the particle/field
information backwards from post- to pre-Big Bang phase (italics mine)." Taken
at face value, this might tend to confirm that particles/fields, that is,
energy, are different from the information about them but inseparable from it,
as some of us have argued. I would be very interested to know how some of you
interpret these concepts. There is a formal resemblance to Feynmann's concept
of anti-particles being normal particles moving backward in time. However, I am
not at all sure that the analogy helps because it refers to thermodynamic time
and this is exactly what disappears in the cosmological framework.
Thank you and best wishes,
Joseph
