Thanks Saul-Paul, so the data is evidence FOR string theory in your opinion.
Interesting!

Jack,
Superstring theory does not view the Planck scale of spacetime as a quantum
foam but rather as the Planck scale is approached the dimensionality of
spacetime goes to 10-d. In string theory the spacetime does fluctuate but
this fluctuation is harmonic rather than chaotic. In fact the assumption
that the harmonics of the strings absorbs all the quantum fluctuation can be
used to derive the dimensionality of spacetime. Also Lorentz invariance is
assumed in this calculation. This was first done by L. Brink and H.B.
Nielsen in 1973 ("A Simple Physical Interpretation of the Critical Dimension
of Space-time in Dual Models," *Physics Letters* 45B:4 (1973) 332-336. This
paper is also included in the anthology edited by John Schwartz,
*Superstrings: the First 15 Years of Superstring Theory, Vol. 1* (World
Scientific, 1985). [Note that "Dual Models" is the old name for string
theory, when it was still evolving away from the terminology of s-matrix
theory. However, the Mandelstam labels of S, T, and U duality have
resurfaced in membrane theory!]
I mentioned the Brink-Nielsen view of string theory in my paper "Notes on
Hyperspace" that I wrote for ISSO & ISEP in November 2000. [See attached
pdf.]
Also on page 6 of F.W. Stecker's pdf paper [referred to in the NASA
report], he says "We note that there are variants of quantum gravity and
large extra dimension models which do not violate Lorentz invariance and for
which the constraints considered here do not apply."
BTW: In the "Acknowledgments" on page 8, Serge Rudaz is one of four
people thanked "for helpful discussions." I remember meeting Serge Rudaz in
1976 at your Nob Hill appartment on (1155?) Jones Street where the PCRG held
seminars. He was then a young physics student (at Cornell?) who was an old
acquaintance of yours. He told us about "instantons" -- which was a new idea
then. I have not heard of him since 1976 -- until seeing this
acknowledgement!
Nuff said!
Saul-Paul
JS: Yes, Serge was with me at UCSC in Summer 1973 when I went to see
Jean Cocteau's Orphee on campus with Helen Quinn (who was close to
having he baby at that time) and I think Serge and a few others. This
was days before I went to SRI to meet with Puthoff and Targ on the tape
you have. The story is in the book "Destiny Matrix".

Thanks Gary. This is actually good news for my theory in which
Einstein's GR is emergent as a c-number ODLRO field out of
a BCS QED vacuum instability that forms the inflation field.
That is, direct quantization of Einstein's guv field is not
appropriate anymore than re-quantizing the giant superfluid and
superconducting waves is appropriate.
Therefore "quantum foam" is suspect. Also Bohm's "quantum potential"
view of "vacuum fluctuations" is relevant in context of the recent
paper from Teheran.
I need to follow the experiment below more carefully.
