GK: When they know what a photon "is" I think they will unify Einstein and quantum mechanics.-I don't think so. I think they are two different levels of reality and cannot be fully combined. > > GK: dwh. we were talking about different times at the beginning of the universe. before you go any further, do you understand what we said about "energy" and a "photon", a "force carrier". What I posted before still stands. > > 'energy" has a few forms. It is based on some type of "particle exchange" and conservation laws. If you like. I will bow out so I don't confuse you.-I don't think you are confusing him. He doesn't understand the concepts of energy at the atomic level and energy at the wood and coal level, as totally different.
