Description
Despite intensive searches, dark matter has not yet been discovered as a particle. Why not? Arguably, most searches are like looking for lost keys only under the lamppost, because that’s where we can see. I will assess how thoroughly we have really searched under the WIMP lamppost, point out opportunities for progress, and discuss the ultimate limitations of such searches. Then I will discuss what’s beyond this lamppost, where we have searched much less thoroughly, and where new ideas --- exploiting cosmic rays, neutron stars, and more --- are catalyzing progress.
