dark matter
Where it comes from
Calque of German Dunkle Materie. The term gained new popularity in the 1970s as a result of Vera Rubin's publishing (in English) her discovery that some galaxies did not seem to have enough mass to account for their rotation curves.
noun
- Matter which cannot be detected by its radiation but whose presence is inferred from gravitational effects. 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.
- Matter which has mass but which does not readily interact with normal matter except through gravitational effects.
- Unclassified or poorly understood genetic material.
