Dark matter is a term used in astrophysics to describe a mysterious form of matter that does not emit, absorb, or reflect light, making it invisible and undetectable by traditional means. Its existence is inferred from its gravitational effects on visible matter and cosmic structures. Although it constitutes about 85% of the universe’s mass, its nature remains unknown. It plays a crucial role in the formation and evolution of galaxies and the overall structure of the cosmos. Various theories suggest it could be composed of undiscovered particles or exotic forms of matter. Dark matter continues to be a fundamental enigma in modern physics and cosmology.
