Substantiivi
- (astronomy, astrophysics, loosely) Matter which cannot be detected by its radiation but whose presence is inferred from gravitational effects.
- (particle physics, cosmology, strictly) Matter which has mass but which does not readily interact with normal matter except through gravitational effects.
- (biology, informal) Unclassified or poorly understood genetic material.
Esimerkit
- The evidence for dark matter in galaxies started to accumulate in the mid-1970s. By the following decade it became clear that essentially all galaxies, including our own Milky Way, are surrounded by extensive halos of dark matter.
- On large scales like that of clusters of galaxies, gravitational lensing indicates that the dark matter is smoothly distributed, on the average.
Luokat
(particle physics, cosmology, strictly) Matter which has mass but which does not readily interact with normal matter except through gravitational effects.
Dark matter map for a patch of sky based on gravitational lensing analysis of a Kilo-Degree Survey
(particle physics, cosmology, strictly) Matter which has mass but which does not readily interact with normal matter except through gravitational effects.
Collage of six cluster collisions with dark matter maps. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide.
(particle physics, cosmology, strictly) Matter which has mass but which does not readily interact with normal matter except through gravitational effects.
DM map by the Cosmic Evolution Survey (COSMOS) using the Hubble Space Telescope (2007)
