Understanding Dark Matter

Dark matter is a form of matter that doesn't interact with light, making it invisible. It can only be detected through its gravitational effects. While it clumps and forms galaxies like ordinary matter, its distribution is different due to its lack of interaction with electromagnetism. Dark matter interacts gravitationally and has a significant role in galaxy formation, driving the collapse of ordinary matter. The precise nature of dark matter is still unknown, and scientists are exploring various possibilities, including the existence of a dark matter disk.
