New dark matter theory could solve multiple cosmic mysteries at once
Physicists at the Chinese Academy of Sciences have proposed a 'two-component' dark matter model to explain anomalies in galaxy formation. The theory suggests that dark matter particles of different masses interact with each other, causing them to segregate within galaxies.
Dark matter has long been one of astronomy's greatest mysteries. It cannot be seen or touched, yet its gravitational influence helps shape galaxies and the large scale structure of the universe. For decades, scientists have relied on the "cold dark matter" model to explain how galaxies formed and evolved. But as telescopes and observations have become more precise, researchers have uncovered several puzzling features that the standard model struggles to explain.
