(Weakly Interacting Massive Particle)
(proposed particle comprising dark matter)

WIMP (or Weakly Interacting Massive Particle) is a proposed Dark Matter element consisting of a particle not affecting Electromagnetic Radiation (EMR) and therefore invisible. It could be an as-yet unknown subatomic particle or could be a known particle with such characteristics, such as the Neutrino (ν), if the numbers and the mass were sufficient. Discovery of candidate particles in accelerators or through detection would comprise evidence for their existence.

An alternative idea is that dark matter consists of larger objects, the term being used for this is MACHO.
