What Is Dark Matter | Frenly Guru

Dark matter is a hypothetical form of matter that does not interact with light or other electromagnetic radiation, making it invisible and detectable only through its gravitational effects. It is thought to make up approximately 26.8% of the universe's mass-energy content, with the remaining 68.2% consisting of a form of energy known as [[dark-energy|dark energy]], and 5% consisting of ordinary matter. Dark matter plays a crucial role in the formation and evolution of galaxies, [[gravitational-lensing|gravitational lensing]], and the large-scale structure of the universe. Its existence is implied by the observed gravitational effects that cannot be explained by [[general-relativity|general relativity]] unless more matter is present than can be observed. The study of dark matter is an active area of research, with scientists using a variety of methods, including [[astrophysics|astrophysical]] observations and [[particle-physics|particle physics]] experiments, to better understand its properties and behavior.
