I know that the weak-electro theory has been doing well, and the Z0 particles makes it almost iron-clad. But the strong force? From what I learned in an intro-to-quantum course, we can solve the electro-magnetic interactions explicitly only because the Fine Structure Constant is less than 1 (~ 1/137). The weak force just happens to be obviously tied to E&M. But the strong force has a constant (analogous to the FSC) that is quite a bit greater than 1 (I don't remember what it is). And don't even talk about tying in gravity. Nobody knows what a 'graviton' looks like. Anybody care to respond? --Randy
