Dark Matter is a mysterious substance that makes up about 27% of the universe, yet it does not emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects. Scientists infer its existence from the way galaxies rotate and how they interact with visible matter, leading to the conclusion that there must be something else exerting gravitational pull. Despite extensive research, the exact nature of Dark Matter remains unknown. It is believed to consist of exotic particles that do not fit into the standard model of particle physics. Understanding Dark Matter is crucial for explaining the structure and evolution of the universe.
