Is a Grand Unified Theory of physics possible?

[EiNsTeiN]

I was in a lecture today, and the lecturer was a scientist from CERN.He is the director of the ALICE expirement in the LHC...

The superstring theory won't be proved true unless the expriment is done, and until then, no one can provide a verification..

It's supposed that the nuclear and the electroweak forces will be unified in the LHC, and that means we will be able to unify all the forces together except the gravitational..

It's a huge step though

I think that a truly unified theory would encompass more than physics. By limiting it to physics, I believe you doom it to impossibility. Unification would necessarily imply everything, no? Our understandings of the mind, life, and everything else would have to be included, or too much is left out and the theory will not conform completely enough to reality.

Unless you are fond of chasing ghosts in the machine (and plenty are), maybe a unified physical explanation is relevant without attempting to explain consciousness. That we are aware of physical phenomena is that we are removed from it. Being removed from it there is no need to include us in a physical explanation. Humans will only ever have a gross experiential understanding of physics, even though the equations might someday balance.

The LHC is the big atom smasher, aye?

I was under the impression that the unification through superstring theory was based upon weaving gravity into the idea. Is that inaccurate?

Maybe there are forces (outside of our universe)that are causing the accelarating expansion of our universe.The physics of these external forces could be totally different from our universe.Not bieng able to dirrectly observe outside our universe it will be tough to come up with a theory for everything.
