fuzzy dark matter

English

Etymology

From the lack of definition (fuzziness) due to the wave-like nature of fuzzy dark matter, unlike the particle-like of hot dark matter and cold dark matter.

Noun

fuzzy dark matter (uncountable)

1. (physics, cosmology, astronomy) A type of dark matter with very low particle mass, with concomitant very large de Broglie wavelength (such as wavelength on the order of kiloparsecs), resulting in a population of overlapping waves, and concentrations of this dark matter modeled as fields and interference patterns, over astronomical and cosmological distances.
