Dark Matter Detection
Exploring methods to detect the invisible matter that shapes our universe
The Dark Matter Mystery
Dark matter constitutes approximately 27% of the universe's total mass-energy content, yet it remains one of the greatest unsolved mysteries in physics. Unlike ordinary matter, dark matter does not emit, absorb, or reflect light, making it invisible to electromagnetic observations.
Its presence is inferred through gravitational effects on visible matter, radiation, and the large-scale structure of the universe. Despite decades of research, the fundamental nature of dark matter particles remains unknown, driving innovative detection strategies across multiple experimental approaches.
Direct Detection
Underground experiments search for dark matter particles interacting with ordinary matter through nuclear recoils.
- • XENON, LZ, PandaX
- • Cryogenic detectors
- • WIMP searches
Indirect Detection
Space and ground-based observatories search for products of dark matter annihilation or decay.
- • Gamma-ray telescopes
- • Neutrino observatories
- • Cosmic ray detectors
Collider Searches
Particle accelerators attempt to create dark matter particles through high-energy collisions.
- • Large Hadron Collider
- • Missing energy signatures
- • Supersymmetry searches
Astrophysical Evidence
Galaxy Rotation Curves
Stars in spiral galaxies orbit at constant speeds regardless of distance from the center, indicating the presence of unseen mass extending far beyond visible matter.
