New dark matter theory explains cosmic mysteries with two particle types

sciencedaily.com

A new theory proposes dark matter consists of at least two particle types that separate over time, potentially solving cosmic mysteries. Heavier dark matter particles sink to galactic centers while lighter ones spread out, explaining observations like diffuse dwarf galaxies and dense clumps causing gravitational lensing. This "two component self interacting dark matter" model, supported by simulations, offers a more complex view of the invisible universe, awaiting further observational tests.
