Dark Matter

Definition of Dark Matter as it relates to Science, Astronomy, Cosmology

Dark Matter is a theoretical form of matter that is believed to account for approximately 85% of the universe's mass. It does not emit, reflect or absorb light, making it extremely difficult to detect. However, its existence is inferred through its gravitational effects on visible matter, such as stars and galaxies. In the context of cosmology, dark matter plays a crucial role in understanding the formation and evolution of large-scale structures in the universe, such as galaxy clusters. It also helps explain the rotation curves of galaxies and the observed flatness of the universe's overall geometry. Dark matter is a fundamental concept in the field of astrophysics and cosmology, and is an active area of research in modern science.
