How is nonbaryonic matter (dark matter) different from baryonic matter, and what do observations suggest nonbaryonic dark matter may be? Nonbaryonic dark matter is made up of quarks instead of leptons and is most probably comprised of neutrinos with very low mass. Nonbaryonic dark matter is much more massive than baryonic matter and is most probably comprised of high-mass neutrinos. Nonbaryonic dark matter does not interact with baryonic matter or with electromagnetic waves, and is probably comprised of weakly interacting massive particles, or WIMPs. Nonbaryonic dark matter only interacts with $\mathrm{x}$-rays and gamma rays and is probably comprised of small b massive objects within galactic halos.
