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
