Some scientists say, that the LHC can "recreate the conditions [quite close to] of the Big Bang". But, what if our Cosmos is Closed ? Then, mere moments after the Big Bang, Space was still "Hyper-Curved", compared to today, after space has expanded for 14 G.yr., and is not very far from Flat. Unless the LHC can recreate those conditions of Hyper-Closed-Curvature, as the "backdrop" for the LHC particle collisions, then High Energy collisions in Flat space (today) != High-Energy collisions in Hyper-Curved Closed space ('Big Bang') (conveying the concept, if being a little imprecise w/ words).

Analysis of the microwave background radiation conclusively shows large scale euclidean geometry; our universe is flat. For the universe to be closed, it must have positive curvature.

Look at the line 5 from the bottom.

 

+ Dark Energy in the vacuum

It's similar to Big Bang condition.

It's our best result at the present.

I think it's just similar energy densities. Of course it would be totally awesome to recreate the spacetime too, but that would be a bit harder than just throwing particles at each other really fast, at least I would hope so.
