I did take a university physics/theoretical that was pretty awe-inspiring. I think boson and superstring theories were the rage, and it was over my head at the time, and I didn't pursue it any further. I still do try to keep up with the current theories and research, but it is certainly not an easy read, nor are the concepts easy to accept either. In the mid '80s , physicists thought they had it all figured out with superstrings and how elementary particles and the interactions between them could fit. In the last 20 years, M-theory, with its 11 dimensions (yes, 11) and string theory landscape are the hot topics. Will the theory of everything occur in our lifetime? Perhaps. Oh, but that also requires us to realize that the earth is more than 5,000 years old. Doesn't the catholic church officially recognize that fact now?
