New research challenges the long-held belief that Sagittarius A* is a supermassive black hole at the Milky Way's center. Instead, scientists propose it could be a dense clump of fermionic dark matter, capable of mimicking the gravitational effects attributed to a black hole.

This dark matter core, with a mass equivalent to 4.6 million suns, would explain the rapid movement of stars and dust-shrouded bodies in the Galactic Center. The theory also accounts for the observed slowdown in the Milky Way's rotation curve, which traditional cold dark matter models struggle to explain.

The team's research, published in Monthly Notices of the Royal Astronomical Society, suggests this fermionic dark matter structure could cast a shadow similar to the one captured by the Event Horizon Telescope in 2022. While the theory challenges conventional understanding, researchers emphasize it's still early days and future observations using the Very Large Telescope will be crucial to test this provocative hypothesis.
