An exotic class of non-baryonic particle, WIMPs (Weakly Interacting Massive Particles) are a prime dark matter candidate. For more about dark matter and WIMPs, check out these pages: The question of dark matter The WIMP experiment Big bang cosmology primer
These as yet undiscovered particles are a leading candidate for dark matter.
Acronym for a Weakly Interacting Massive Particle, a possible form for cold dark matter.
A very Weakly Interacting relatively Massive elementary Particle. WIMPs have not yet been observed.
a hypothetical subatomic particle of large mass that interacts weakly with ordinary matter through gravitation; postulated as a constituent of the dark matter of the universe
a Weakly Interacting Massive Particle, a possible form for cold dark matter. : is the symbol used for the redshift. The formula is 1+z = lambda(obs)/lambda(em) where lambda is the wavelength of a line emitted at lambda(em) but observed at lambda(obs).
WIMP stands for "Weakly Interacting Massive Particles." They are hypothetical particles that have a non-zero mass and only participate in weak nuclear interactions. Dark matter may be composed of WIMP's.
