What if dark matter isn't matter at all, but a repulsive gravitational effect that creates negative curvature in spacetime, indirectly pushing matter together by sculpting spacetime differently?
Reimagining dark matter as a repulsive gravitational effect
Instead of being "extra mass" attracting things (as the current model assumes), this theory proposes that dark matter is not matter at all, but a repulsive gravitational effect that creates negative curvature in spacetime in certain regions.
In this framework, dark matter isn't pulling galaxies together — it's shaping spacetime so that matter clumps without needing extra mass. This represents a fundamental shift in how we conceptualize the dark matter problem.
By introducing regions of negative curvature in spacetime, this theory can potentially explain the observed galaxy rotation curves, gravitational lensing, and large-scale structure of the universe without requiring invisible particles.
