What is dark matter?

Dark matter is made of non-Baryonic matter

This position holds that dark matter is made of non-baryonic matter — not ordinary atoms but more exotic particles. It points to leading candidates such as axions and Weakly Interacting Massive Particles (WIMPs) as what the universe's unseen mass is likely composed of.

  1. Dark matter is made of axions
    In the 1970s, Scientists proposed axions as small particles that help balance neutrons and make them symmetrical. Because of the vast number of axions, scientists proposed them as candidates of dark matter in the universe.
  2. Dark matter is made of WIMPs
    Weakly Interacting Massive Particles (WIMPS) have been attractive candidates for what may make up dark matter. Scientists place hope on WIMPs as particles that would connect the large cosmic scale of physics to the standard models of physics.
