Dark Matter's Surprising Origin: Fast Particles Slowing Down

Dartmouth researchers propose a novel theory for dark matter's origin. Their model suggests that in the early universe, high-energy massless particles collided and rapidly condensed, akin to steam turning into water, forming dark matter. These particles, attracted by opposing spins, cooled, and their energy plummeted, transforming into cold, heavy particles. The theory is testable via analysis of the cosmic microwave background radiation and draws an analogy to Cooper pair formation in superconductivity.
