Rotation Curves and the Dark Matter Debate: Are We Missing Something?
Galaxy rotation curves have perplexed astronomers for decades, posing a significant challenge to our understanding of gravity and the universe’s composition. The core issue lies in the observation that stars in galaxies do not slow their rotation as expected when they are farther from the galactic center. Instead, the velocity remains constant or even increases,…
