Ok so I'm a bit confused. We have a confirmed electroweak theory - electromagnetism and the weak nuclear force were unified through the gauge principle and the fact that they merge into one force at high enough energies.
Merging the strong nuclear force with electroweak would give us a Grand Unified Theory, of the electronuclear force. What I don't understand though is this - the strong nuclear force is also described by gauge theory. We have also confirmed that at even higher energies (even earlier moments of our universe), we have an electronuclear force.
So why is the strong nuclear force not regarded as being unified with the electroweak force? Is it that we know that they are unified at high energies, it's just we can't explain why (e.g. the fact that baryons have to be able to convert into leptons, something we can't account for at the moment?)
I just don't understand what it is that means we don't have a GUT. It seems to me that that we've already described how the three forces are unified by the gauge principle, and know that they're different because of symmetry breaking.
If someone could enlighten me that'd be great, thanks :)
