Physics - Dark matter

Dark matter is a mysterious form of matter that does not emit, absorb, or reflect light, making it invisible to current telescopes. It constitutes about 27% of the universe's total mass-energy content, influencing the motion of galaxies and large-scale structures through its gravitational effects. Despite extensive research, the nature of dark matter remains unknown, with leading candidates including WIMPs and axions. Understanding dark matter is crucial to uncovering the universe's fundamental composition and evolution.
