Dark matter is a hypothetical form of matter that is believed to account for approximately 85% of the matter in the universe and about a quarter of its total energy density. Its presence is inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe, rather than any direct physical interactions that produce detectable light or radiation. Dark matter does not emit, absorb, or reflect light, making it extremely difficult to detect with existing astronomical instruments. The exact nature of dark matter remains one of the foremost mysteries in astrophysics. Various theories suggest that dark matter could be composed of undiscovered subatomic particles, such as weakly interacting massive particles (WIMPs), axions, or sterile neutrinos. Understanding dark matter is crucial for providing a more complete picture of the universe’s composition, the formation of galaxies, and the dynamics of cosmic structures. Large-scale experiments and astronomical observations continue to search for signs of dark matter particles.
