Re: TOTAL SCIENTIFIC FAILURE: LHC Proves String Theory WRONG!
Actually, the Bible is riddled with inconsistencies too.
And yes, I agree - the abscence of instantly-decaying black holes proves the ADD (Arkani-Hamed Dimopoulos Dvali) model wrong — as the unification presented in that theory has consequences for gravity. Normally, gravity is very weak relative to the other forces, such that it could only become unified with the rest of them at energies many orders of magnitude higher than the LHC could reach. But, in the ADD model, gravity only looks weak because portions of it are caught up in the remaining dimensions. This drops the energies down to something right in the heart of the LHC’s capabilities.
If everything went as the model proposes, particles that collided at energies above this cutoff could close to within a distance that’s smaller than the space occupied by the additional dimensions. Once that happens, they’d feel the full force of gravity, and immediately merge to form a tiny black hole. So tiny, in fact, that it would instantly decay via Hawking radiation. This decay would be visible as jets of particles, something that can't be missed, and something that wasn't found in the LHC.
And, contrary to your report, this result doesn’t mean the death of string theory, only the particular flavour - the ADD model - that predicted black holes at these energies. Eliminating some models is a critical process of narrowing down what’s possible, but most theoretical constructs have a range of possible models, and string theory is no different. In fact, it’s entirely possible that the ADD model was generated simply because physicists were looking for something they could possibly test in the LHC.
Ultimately, this benefits - not destroys string theory, because now the possible implications have been further narrowed down!
