I thought string theory had been superseded by M theory? (Membrane theory)
Maybe...I based my comments on an article I read in a physics journal awhile back. The author did not believe in string theory. He said that since most university physicists are all-in for string theory, when it goes bust it will mean decades of wasted research.
Even though I have taught physics, my primary training is in chemistry. So I'll just stick with the periodic table for answers.
