Dark Matter

About

Dark matter is an invisible form of matter that is known to exist due to its gravitational effects on visible matter. It does not interact with light or other electromagnetic radiation, making it undetectable by conventional means. Dark matter is crucial for explaining phenomena such as the rotation curves of galaxies and the formation of galaxy clusters. It is believed to make up approximately 85% of the universe's total matter, significantly outweighing ordinary matter. The composition of dark matter remains a mystery, with various theories proposing it could be composed of particles like WIMPs (weakly interacting massive particles) or axions. These particles would interact with normal matter primarily through gravity. Despite extensive research, direct detection of dark matter has not been achieved, and its existence is inferred from its gravitational influence on observable structures in the universe. Ongoing experiments and observations continue to explore the nature of dark matter, aiming to uncover its secrets and understand its role in the cosmos.
