Hace 1 día · In astronomy, dark matter is a hypothetical form of matter that appears not to interact with light or the electromagnetic field. Dark matter is implied by gravitational effects which cannot be explained by general relativity unless more matter is present than can be seen.
25 de may. de 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).

Hace 5 días · Los científicos la denominan materia oscura. Al igual que la energía oscura, hay mucho de lo que no sabemos sobre la materia oscura. Pero al parecer, un 27% del universo, o cerca de un cuarto, está compuesto de esa cosa extraña. En conjunto, la energía oscura y la materia oscura componen el 95% del universo. Eso es casi todo el universo.
