"There's definitely physics in this world that's beyond the standard model, there's definitely more to neutrinos than we know, and there's definitely something stopping CP violation from occurring in the strong interactions. There may also be extra dimensions, grand unification, supersymmetry, or something even more exotic or surprising. But all of these possibilities require new particles, many of which make good dark matter candidates, and all of which have unknown particle parameters.
...
We've got lots of options and lots of searches going, but there's so much we don't know about it at this point! Cross-sections, masses, reaction rates, lifetimes, etc., they're all mysteries at this point. We may not know what dark matter is, exactly, but we've got lots of strong possibilities for what it could be, and some hints that simply can't be ignored. We're desperately trying to be able to detect it directly, and solve this mystery once and for all. Welcome to the cutting edge!"
