How plausible is a grand unified field theory?  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?
