Rayraz, You see the elison next to the 1/4Pi in the first equation? I think that refers to exponet; as i/4pi radians times the exponet where if the exponet is two you have 3 dimentions if it is three you have 4 dimensios etc. the energy you speak of might go into one of these other dimensions. If you have a serious interest you could start by logging on to mkaku.org - besides the fact that I'm pretty sure I met him when we were kids, he's a favorite because he has a way of explaining this stuff in a simple manner. He has a weekly radio program you might be able to access through streaming video either on his site or through kpfa radio station sorry you'll have to do a google for that one. If you're lucky and have a good physics prof you can talk to, you could visit him at office hours with these types of questions. - I don't know how many times I visited old Dr. Brown to ask him questions - even if I didn't always understand what he said it was worth it to see his eyes light up to realize that someone had an interest in what he had to say on physics. ***** Hey don't you have a Math Exam on monday? !!! ?? (or was that last week - time is so confusing.)
