Dark matter is essential to our understanding of the universe because it cannot be observed directly through electromagnetic radiation. Its existence is inferred from its gravitational effects on visible matter, such as stars and galaxies.
Observations and Evidence

Observations of the rotation of galaxies, gravitational lensing, and the cosmic microwave background radiation all point towards the presence of dark matter in the universe. These pieces of evidence have led scientists to conclude that dark matter makes up about 27% of the total mass-energy content of the universe.
Dark Matter Particles
The leading candidate for dark matter is a type of particle that does not interact with electromagnetic forces, known as a weakly interacting massive particle (WIMP). WIMPs are hypothesized to be abundant in the universe and may play a crucial role in shaping the large-scale structure of the cosmos.
Research and Experiments
Scientists have been conducting experiments to detect dark matter particles directly or indirectly. Some of the most well-known experiments include the Large Hadron Collider at CERN, the Cryogenic Dark Matter Search, and the Alpha Magnetic Spectrometer aboard the International Space Station.

Various theories and models have been proposed to explain the nature of dark matter, including supersymmetry, axions, and sterile neutrinos. Each of these theories offers a different perspective on the origin and interactions of dark matter particles.
Challenges and Limitations
Despite the progress made in unraveling the mystery of dark matter, there are still many challenges and limitations in our understanding of this elusive substance. The lack of direct detection and the existence of competing theories continue to complicate the search for dark matter.
Future Prospects
Advancements in technology and scientific research are expected to shed more light on the nature of dark matter in the coming years. New experiments, such as the Large Synoptic Survey Telescope and the European Space Agency’s Euclid mission, will provide valuable data that could help unravel the mystery of dark matter once and for all.
