In astronomy, dark matter is a hypothetical form of matter that does not interact with light or other electromagnetic radiation. Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be observed.

Dark Matter est une série télévisée américaine de science-fiction créée par Blake Crouch, basée sur son roman éponyme de 2016. Elle est diffusée depuis le 8 mai 2024 sur Apple TV+ [1].
1 oct. 2024 · dark matter, a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).
9 mai 2018 · Physicists and astronomers have determined that most of the material in the universe is “dark matter”—whose existence we infer from its gravitational effects but not through electromagnetic...
Matter is defined as any substance that has mass and occupies space. But there’s more to the universe than the matter we can see. Dark matter and dark energy are mysterious substances that affect and shape the cosmos, and scientists are still trying to figure them out. Learn more.
Dark matter seems to outweigh visible matter roughly six to one, making up about 27% of the universe. Here's a sobering fact: The matter we know and that makes up all stars and galaxies only accounts for 5% of the content of the universe! But what is dark matter? One idea is that it could contain "supersymmetric particles" – hypothesized ...
La matière noire, invisible, compose une grande partie de l’Univers ; toutefois, nous ne pouvons la détecter qu’à partir de ses effets gravitationnels. Les galaxies de notre Univers semblent arriver à réaliser une véritable prouesse.
Dark matter provides the surplus gravity. Scientists have confirmed earlier observations by measuring how much matter in the very early universe is “normal” and how much is “dark” using experiments like NASA’s Wilkinson Microwave Anisotropy Probe (WMAP).
Dark matter is invisible to observations across the optical spectrum, and is observed primarily by its gravitational effects. Without the binding effects of dark matter, the galaxies would not have formed, the stars would not shine, and life would not exist.
