The Dark Matter Mystery
Dark matter makes up about 27% of the universe, yet we can't see it directly. It's one of the biggest mysteries in modern physics.
The Evidence
- Galaxy rotation curves
- Gravitational lensing
- Large-scale structure formation
- Cosmic microwave background
What Could It Be?
Leading candidates include:
- WIMPs (Weakly Interacting Massive Particles)
- Axions
- Sterile neutrinos
- Primordial black holes
The Search Continues
Experiments like LUX-ZEPLIN and Euclid are pushing the boundaries of our ability to detect dark matter directly and map its distribution across the cosmos.
