Matt Visser's Review of Sakharov's Emergent Gravity
Jack Sarfatti
of vacuum coherence which seems to be uniquely original to my theory in
the precise way I mean it. It is not in Modanese, not in Volovik, not in
Ning Li et-al - definitely not in anything Puthoff, Haisch et-al have
written.
When I use "vacuum coherence" I mean a QED BCS type vacuum instability
causing the inflation field to form where Einstein's gravity emerges
from the coherent Goldstone phase of the inflation field and the unified
w = -1 dark energy/matter is controlled by the Higgs intensity of the
inflation field.
I have a dynamics for inflation not found in current adhoc models.
What is wrong with Visser's paper is that it impliciltly assumes
vacuum coherence = 0
Visser does not ask the right question.
"The Question is: What is the Question?"

Thanks, I had not seen it. Very useful. :-)

Dear Jack,
Here I send you a link to a nice paper on "induced gravity"

Sakharov's induced gravity: a modern perspective
by Matt Visser (Washington University in Saint Louis)
Mod.Phys.Lett. A17 (2002) 977-992
Possibly you are aware of this paper, but if you haven't read it it nicely
present several ways to develop the Sakharov's idea for "emergent" gravity
that needs not micro-quantization.
The author derives important conclusions and compares the 4 ways one can go
after accepting Sakharov's idea that gravity is emergent
1. Sakharov: Demand one-loop dominance.
2. Pauli: Demand one-loop finiteness.
3. Frolov-Fursaev: Demand one-loop calculability.
4. Renormalizability: Demand one-loop calculability for certain differences.
You should read the paper but what impressed me is that one of the
interesting approaches suggested by Frolov & Fursaev was systematically used
by them to model black holes and the associated phenomena. So the original
Sakharov's idea is possibly viable alternative to micro-quantum gravity as
you call it.
p.s. My recent interest in the theory of vacuum was after reading the
original book of Roman Podolny written in 1983 called "Something called
Nothing". For pitty I don't know from where this book can be obtained in
English [I will need 4-5 months spent to translate it].
Currently I am interested also in the superconductive properties of the
vacuum and download from arXiv papers from Andrei Linde, and also I will try
to find something of Iakov Zeldovich who worked on the theory of vacuum.
Here is list with papers from Frolov & Fursaev. I hope you can find
something interesting in the papers whose links I send you.
Best,
Danko
