Hello, I have read a few books on the subject of String theory, including The Elegant Universe and Fabric of the Cosmos by Brian Greene (that guy is AWESOME!). Anyway, Mr. Greene may have answered my questions somewhere in his books, but the other day, I heard someone say that strings are tiny vibrating strands of energy. Correct me if I'm wrong, but isn't everything in the universe, including energy supposed to be made up of strings, according to this theory? So, if I'm right in saying that, there seems to be a paradox here. How can strings be pure energy if they make up energy?
