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.
