MIT physicists discover surprising twist in Milky Way’s core

Posted by in categories: cosmology, physics

MIT physicists have discovered a surprising twist in the Milky Way’s rotation curve that challenges our understanding of dark matter. By tracking the speed of stars across the galaxy, they’ve uncovered a potential deficit of dark matter at the galactic core.

Traditionally, astronomers believed that dark matter was responsible for the galaxy’s rotation. Still, the new analysis raises the possibility that the Milky Way’s gravitational center may be lighter in mass than previously thought.
