DF9 Galaxy Challenges Dark Matter Theory

Astronomers just found DF9, a galaxy so dim it’s a hundred times fainter than the last two “ghost galaxies” they discovered—and it’s practically empty of dark matter. This third find is shaking up cosmic theory: it’s the strongest evidence yet that these galaxies formed when two massive galaxies collided violently, ripping apart ordinary matter from dark matter. It’s not just rewriting the story of galaxy birth—it’s proving dark matter is real, physical stuff, not just a gravity tweak. Support the show:Get a discount at https://solipillow.com/discount/dnn.
