Two-Particle Dark Matter Theory Could Explain Cosmic Signals

A new study suggests that dark matter may consist of two distinct particles, helping explain why cosmic signals vary across the universe. This model accounts for the gamma-ray excess at the center of the Milky Way while remaining absent in smaller systems like dwarf galaxies.

Instead of ruling out dark matter, these differences point to a more complex and environment-dependent nature, opening new directions for understanding how this invisible substance shapes the cosmos.
