Dark Matter Formed When Fast Particles Slowed Down and Got Heavy, New Theory Says
Dartmouth researchers propose that dark matter originated from massless, light-like particles in the early universe that rapidly condensed into massive particles through a spin-based interaction. Phys.Org reports: [T]he study authors write that their theory is distinct because it can be tested usin...
The extremely low-energy particles they suggest make up dark matter would have a unique signature on the cosmic microwave background, or CMB, the leftover radiation from the Big Bang that fills all of the universe. "Dark matter started its life as near-massless relativistic particles, almost like light," says Robert Caldwell, a professor of physics and astronomy and the paper's senior author. Hot, fast-moving particles dominated the cosmos after the burst of energy known as the Big Bang that scientists believe triggered the universe's expansion 13.7 billion years ago.
