Is dark matter ’natural?’ Physicist puts the question to the test

Dark matter is one of the oldest open problems in physics. It makes up most of the matter in the universe and shapes how galaxies form and move, yet no one has ever directly detected it. Physicists have proposed dozens of candidates to explain it: exotic new particles, black holes formed moments after the Big Bang and more.
