The MAGIC of SSC and how it affects LHC

We discuss the phenomenology of Supercritical String Cosmology (SSC) in the context of Dark Matter constraints on supersymmetric particle physics models at LHC. We also link our results with recent findings of the MAGIC, H.E.S.S. and Fermi Telescopes on delayed arrival of highly energetic photons from the distant Galaxies and GRBs. The link is provided by a concrete model of space-time foam in (supercritical) string theory, involving space-time defects and their interaction with matter in a brane world scenario.
