Dear Dr. Shinji,

May I ask you to help me understand three puzzles of the inflaton field.

In your recent "Introductory review of cosmic inflation", hep-ph/0304257 [Ref. 1], you wrote:

"In fact temperature anisotropies observed by the COBE satellite in 1992 exhibit nearly scale-invariant spectra as predicted by the inflationary paradigm. Recent observations of WMAP also show strong evidence for inflation [11]."

1. Can any of the inflationary models -- R^2, new, chaotic, extended, power-law, hybrid, natural, supernatural, extranatural, eternal, D-term, F-term, brane, oscillating, trace-anomaly driven, ..., etc. -- explain the so-called cosmic equator and pin down the topology of space? Please see

You also wrote [Ref. 1]: "When the inflationary period ends, the evolution of the universe is followed by the standard big-bang cosmology, and the comoving Hubble radius begins to increase. Then the scales of perturbations cross inside the Hubble radius again (the second horizon crossing), after which causality works."

2. How can you restore the causality "during" a period of "time" in which it is gone, zilch, non-existent?

Many years ago, in April 1986, Yakov Zel'dovich wrote me a nice letter in which he explained the big bang scenario as follows: "Long time ago there was a period of time during which there was still no time at all."

To explain this ultimate puzzle, imagine a super-powerful vacuum cleaner which suck everything, following strictly the deflation time,

At some critical moment, the vacuum cleaner will suck itself and will cease to exist, as pointed out by the late Yakov Zel'dovich.

3. Can you explain this miracle without the Aristotelian Prima Cause or Unmoved Mover? Please see

I very much hope to hear from you and from your colleagues.

Thank you very much for your time, as read by your clock.

Sincerely yours,

Dimi Chakalov

Tsujikawa-san,

Do you remember my email from Thu, 01 May 2003 14:18:22 +0300? You could have saved a lot of unneeded efforts and confusion with your "Dynamics of dark energy", arXiv:hep-th/0603057v3:

" ... the possibility that Einstein's equations themselves require some form
of modification, in other words the geometry part of the calculation needs
rethinking. Although there is no reason as of yet to believe this is the
case, it is perfectly possible and so we have spent some time looking at
alternatives to Einstein gravity as a source of the current acceleration
today. As we have mentioned, there is more that we have not dealt with, than we have."

Take some ideas from Aristotle,
