String Theory Quote of the Day

This is from Zwiebach's book:

String theorists sometimes say that string theory has already made at least one successful prediction: it predicted gravity!

Right on brother!

Actually, though this is humorous, it is also factual. In all of our searching to find a theory that describes gravity at every energy scale, we came across a theory that gives gravity as a prediction. On one hand it is funny, but on the other it is also interesting.
