Hi Syntax Vorlon,
Just thought I'd give you a little more information. I'm working on one of the 4 main detectors of the LHC (LHCb).
I would like to point out that none of these detectors are looking into the shape of the universe, but instead, the structure. One of the aims of the detector you were refering to (ATLAS), will be trying to find out whether or not the present theory of the unification of forces (super-symmetry) is correct. The theory origonally predicted super-symmetric particles existed at lower energies and would be able to be seen by detectors within the energy ranges of the present generation of accelerators. However, when the detectors failed to find them, the theory was adapted to give a distorted picture, and it is now saying that they will be able to be seen within the energy limit of the LHC (14TeV: 7 TeV + 7 TeV). To be fair to the theorists though, they have also stated that if super-symmetric particles are not found within this limit, then they can not exist. The theory of super-symmetry is a rather loose theory in that it has I believe over 130 free parameters. Because of this, the theory is able to adapt to any possible outcome except for the one where SuSy particles are not found, and because of this massive adaptability of the theory, there comes a lot of sceptism as to whether or not the theory is really right anyway.
The main aim of ATLAS though will be to verify whether or not the Higg's exists... Looking for mini black holes is a side issue.
You may be interested in looking at LHCb which is a dedicated B-Physics experiment looking at charge-parity (CP) violations through the decay of B mesons, in the aim of verifying the validity of the CKM matrix. Why you may ask? Because the CKM matrix is the theory that describes the process to some degree as to why pure energy tends more greatly to matter than antimatter.
At the end of the day though, any findings of the LHC will only be able to supply observations about the structure of the universe in which we live. It will not be able to prove or disprove the big bang theory, or with absolute certainty prove that present theories about the structure of the universe are absolutely correct, regardless of outcome.
