If so, then string theory is true
as it also predicts explicitly the Standard Model.
However that is not sufficient evidence for physicists
to think string theory is true.
What is needed for string theory to be true
is new physics to be experimentally verified
like the string theory prediction of the viscosity
of the quark-gluon plasma which has already been verified.
Does comp predict any new physics that can be experimentally verified?

Dear Richard,
Forgive me but string theory predicts a HUGE landscape of possible
physics, not just the Standard model. This is its fatal flaw, IMHO.
