Weakly Interacting Massive Particles, or WIMPs, represent one hypothesized class of particles to explain dark matter. They neither absorb nor emit light and don't interact strongly with other particles. But when they encounter each other, they annihilate and make gamma rays.
Which of the following is a weakly interacting massive particle?
WIMPs are Weakly Interacting Massive Particles, hypothetical particles which may be the main (or only) component of Dark Matter, a form of matter which emits and absorbs no light and which comprises approx 75% of all mass in the observable universe.
Do WIMPs interact with light?
It not only doesn't emit or absorb light, but it doesn't interact with any of the known, directly detectable particles through the electromagnetic, strong, or weak nuclear forces. The most sought after dark matter candidate is the WIMP: the Weakly Interacting Massive Particle.
