Mystery AtlasDark Matter Particle Hypothesis
The mainstream cosmological explanation that dark matter consists of a still-undiscovered particle, most often modelled as a WIMP (weakly interacting massive particle) or an axion, that interacts gravitationally but barely or not at all through electromagnetism; supported by independent evidence from rotation curves, gravitational lensing, and the cosmic microwave background, but not yet confirmed by any direct-detection experiment.

Dark Matter Particle Hypothesis attempts to explain Dark Matter — The current cosmological consensus, backed by independent lines of evidence: rotation curves, gravitational lensing, the cosmic microwave background's structure, and cluster collisions such as the Bullet Cluster. No direct-detection experiment has yet confirmed a candidate particle.
