Dark Matter
Dark matter is a hypothetical form of matter that does not emit, absorb, or reflect electromagnetic radiation, inferred through its gravitational effects on visible matter and cosmic structure.
Overview
In cosmological models such as the Lambda-CDM framework, dark matter accounts for approximately 27% of the universe's total mass-energy content, compared to ordinary baryonic matter at roughly 5%. It provides the gravitational scaffolding required for the formation and cohesion of galaxies and galaxy clusters, explaining observed galactic rotation curves where outer stars orbit at velocities exceeding predictions based on visible mass.
Why it matters
Dark matter serves as a central component of the Lambda Cold Dark Matter model in modern astrophysics. Its fundamental nature remains unconfirmed, motivating experimental detection programs directed toward theoretical candidates such as weakly interacting massive particles, axions, and sterile neutrinos.
