While this isn't the end for supersymmetry, it is a blow for our understanding of what lies beyond the Standard Model.
The Ugly: A Dark Dilemma Understanding the nature of dark matter and dark energy are two of the biggest challenges for all of physics, from the quantum world to cosmology. Supersymmetry - which predicts that for every particle of "normal" matter there's a "superpartner" particle - may help explain why 95 percent of the mass-energy of the universe is invisible. (Dark matter has been detected indirectly by its gravitational impact on normal matter and dark energy is the invisible force that has been indirectly observed as the force that accelerates the expansion of the universe.)
But if we cannot detect any evidence of supersymmetry, what the heck is dark matter and dark energy? Let alone gravity; that ‘everyday' force remains as mysterious as ever.
Unfortunately, until the LHC turns up supersymmetry evidence, or spits out some totally unpredictable exotic dark matter particle, dark matter and dark energy will remain a mystery. And as for supersymmetry theory, well, it will soldier on while physicists push particle accelerators to ever higher energies in the hope of seeing over the Standard Model horizon and into a new landscape of exotic physics that may, or may not be, supersymmetrical in nature.
