Dark Matter Decay May Explain Early Universe Supermassive Black Holes

Astronomers using the James Webb Space Telescope have discovered supermassive black holes that formed within the first billion years of the universe, challenging existing theories. Researchers now propose that decaying dark matter particles with masses between 24-27 electronvolts may have released enough energy to prevent gas cloud fragmentation, causing direct collapse into massive black holes instead of star formation.
