Dark matter, matter in the universe that does not emit, absorb or reflect light, cannot be directly detected using conventional telescopes or other imaging technologies. Astrophysicists have thus been trying to identify alternative ...
A new analysis by a team of physicists offers an innovative means to predict "cosmological signatures" for models of dark matter.
