Milky Way’s Core May Be a Dense Dark Matter Core, Not a Black Hole

A new study proposes the Milky Way’s central mass could be a dense fermionic dark matter core rather than Sagittarius A*, capable of reproducing the observed fast S-star orbits and the galaxy’s Keplerian rotation decline, and it might even mimic the black hole shadow seen by the Event Horizon Telescope; while provocative, the idea isn’t yet proven and future observations are needed to confirm or refute it.
