LIGO Has The Dark Matter By The Tail
We now have good reason to believe that stellar-mass ultracompacts (e.g., primordial black holes and neutron stars) are at least as numerous as the luminous stars in our galaxy. So that amounts to several 100 billion dark objects.
If that number continues to go up by about a factor of five, which is hardly unreasonable, then the dark matter enigma is solved.
Microlensing, LIGO/Virgo, Gamma Ray observatories, and Fast Radio Burst results will have led us into the light regarding the dark matter. All that time, money, effort, and careers spent on the poorly motivated and thoroughly obsessive WIMP/axion/sparticle/etc. hunt will have been wasted.
