⚛️ Milky Way Center: New Light on Dark MatterA recent study suggests that sub-GeV dark matter could explain two long-standing mysteries observed at the Milky Way's center. Specifically, the proposed light dark matter particles annihilating in the Central Molecular Zone (CMZ) could produce electron-positron pairs, leading to the unusually high ionization rates detected there. This same mechanism might also account for the unexplained 511 keV gamma-ray emission emanating from the galactic center, which is believed to result from positron annihilation. By linking these two phenomena, the study offers a unified framework that challenges conventional dark matter theories focused on heavier particles. If confirmed, this model would necessitate new approaches in dark matter detection and open new avenues for astrophysical and particle physics research.
