Dark matter is a mysterious substance that makes up most of the matter in the universe, but does not interact with light or other electromagnetic radiation. Scientists have inferred its existence from its gravitational effects on visible matter, such as stars and galaxies.[1]
There are different theories about what dark matter is made of, but none of them have been confirmed by direct observation. Some possible candidates are:
- Weakly interacting massive particles (WIMPs): These are hypothetical particles that only interact through gravity and the weak nuclear force. They are predicted by some extensions of the standard model of particle physics, such as supersymmetry
- Axions: These are hypothetical particles that are very light and very weakly interacting. They were proposed to solve a problem in quantum chromodynamics, the theory of the strong nuclear force[2]
- Primordial black holes: These are black holes that formed in the early universe, before stars and galaxies. They could have a wide range of masses and sizes, depending on the conditions of their formation[2]
Scientists are trying to detect dark matter particles directly using various experiments, such as underground detectors, space telescopes, and particle colliders. However, so far none of these experiments have found conclusive evidence for dark matter25
Dark matter is one of the biggest mysteries in modern physics and cosmology. It has profound implications for our understanding of the origin, structure, and fate of the universe.
