This Is The Real Reason We Haven’t Directly Detected Dark Matter

“So we keep looking, we keep thinking of new possibilities for what it could be, and we keep thinking of new ways to search for it. That’s what science at the frontiers is like. Personally, I don’t expect these direct detection attempts to be successful; we’re stabbing in the dark hoping we hit something, and there are little-to-no good reasons for dark matter to be in these ranges. But it’s what we could see, so we go for it. If we find it, Nobel Prizes and new physics discoveries for everyone, and if we don’t, we know a little more about where the new physics isn’t. But just as you shouldn’t fall for the hyper-sensationalized claims that dark matter has been directly detected, you shouldn’t fall for the ones that say “there’s no dark matter” because a direct detection experiment failed.”

At some point, when you’re looking for an unknown, you have to give up and declare it isn’t there. Sometimes you’re right, and other times, you discover that you either weren’t looking in the right place, or weren’t looking in the right way. It took over 25 years to find the neutrino from when Pauli first proposed it; over 50 years to find the Higgs boson from when it was first theorized; and over a century to find the first gravitational wave, first predicted by Einstein’s theory in 1915. So why, then, would we give up so quickly after not finding dark matter, after only a few decades of looking under a particular set of assumptions?

Dark matter isn’t easy to find, but it isn’t supposed to be. Absence of evidence is not evidence of absence. Learn the real reason we haven’t detected it, yet, today.
