Browsing: Dark Matter
Dark matter is a mysterious and invisible form of matter that makes up about 27% of the universe, yet it does not emit, absorb, or reflect light, making it undetectable by traditional means. Its presence is inferred from its gravitational effects on galaxies, galaxy clusters, and the large-scale structure of the cosmos. Despite decades of research, the true nature of dark matter remains one of the biggest open questions in physics. Stay informed on the latest discoveries, experiments, and theories aiming to uncover what dark matter is and how it shapes the universe.
