A new experiment (it's true a small scale one with the possibility of being brought to a much larger scale) has failed to find any sign of Dark Matter (DM), like all the other experiments before (at least the ground based one). AMS seems to have found some important extra anti-protons and positrons, that might be consistent with DM annihilation, but even so, it could be alternative explanations (and this wouldn't count as a direct detection, anyway). I was wondering what the Physics Forums community thinks about this lack of evidence for DM despite numerous and different approaches to find it (DAMA/LIBRA experiment claims to have found it, but no one was able to reproduce their results). Do we need a fundamentally new detection method (after all, even colliders won't be able to go too much higher in energy, for sure nowhere close to Plank scale anytime soon, so we do need a new approach for high energies)? Do we need some totally new theoretical ideas to describe Dark Matter, in a complete opposite direction from the current models? Do we need to give up on DM completely and find a new explanation for the observed gravitational behavior of the galaxies (MOND?)? What do you think?
