String Theory was once believed to be so highly constrained
that it might uniquely
determine all the parameters in the Standard Model. However, we now
know that there are a near-infinitude
of possible compactifications of string theory to four dimensions, and
each of these compactifications may
in turn have many different low-energy limits. Given this state of
affairs, does String Theory retain any predictive power?
Is there a sense in which the Standard Model is a "typical" or
"likely" low-energy limit?
