Subject: Re: Multiverse concepts in
string theory
Hi Norman,
It will be a wonderful thing to get a
confirmation by next year but I am afraid that the usual behavior of theorist
will occur: the theory will be re-tinkered so that the particle masses are too
massive to be created by humans. It has been happening already in
astrophysics...
Btw, have you any familiarity with
modeling the dynamics of scalar fields in relativistic situations? I need some
help. ;-)
Onward!
Stephen

Stephen,
As you say, the version of string theory with an
infinity of universes is an elegant concept. However, when you
say ". . . its most fundamental assumption, the existence of a
supersymmerty relation between bosons and fermions, has never even come
close to matching experimental observation," one could infer that there
is little likelihood that SUSY will ever be shown to be a good
theory.
This may change soon. Wikipedia says
"Experimentalists have not yet found any superpartners for known particles,
either because they are too massive to be created in our current particle
accelerators, or because they may not exist at all. By the year
2007, the Large Hadron Collider at CERN should be ready for use, producing
collisions at sufficiently high energies to detect the superpartners many
theorists hope to see."
So maybe, in a couple of years, there WILL be experimental
observation supporting SUSY.
I agree that the posts by Hal Finney and Wei Dai are well
said and inspirational. Thanks,
Norman
