What Is Dark Matter | Mamamimi Me

Dark matter is implied by gravitational effects that cannot be explained by general relativity unless more matter is present than can be observed. It is thought to serve as gravitational scaffolding for cosmic structures, and its presence is inferred by its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. The study of dark matter is an active area of research, with scientists using a variety of experiments and observations to detect and study dark matter, including the use of gravitational lensing and the analysis of cosmic microwave background radiation. Dark matter is a key component of the standard Lambda-CDM model of cosmology, which describes the evolution and composition of the universe.
