Story summary
- A study in the Journal of Cosmology and Astroparticle Physics argues that the absence of dark matter signals in galaxies does not contradict Milky Way evidence.
- Researchers propose two distinct dark matter particle types, which change annihilation rates based on environmental balance.
- The model explains why gamma-ray emissions are detected in the Milky Way but not in dwarf galaxies.
- Future observations by the Fermi Gamma-ray Telescope will test this theory.
