Will the String Theory Tie Them All Together?

It is quite unlikely that string theory will be able to achieve all that is mentioned in the conclusions. It has been clear for some time now that the theory has no unique vacuum (representing something similar to our universe) instead it has billions upon billions of consistent vacua even non-perturbatively. This fact alone reduces the predictive power of the theory. The fact that it seems to be a consistent theory of quantum gravity is a major reason why so many people are working on it (since nobody understands what string theory really is non-perturbatively it is hoped that once it is understood everything will work out ok). However, string theory is not the only theory which claims to be consistent with quantum mechanics and general relativity. The other approach known as ``loop quantum gravity`` also has many strong points, but certainly not ``sexy`` enough for people to pay attention.

Will the String Theory Tie Them All Together?
I hope so.
