    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.

  3. With Joel Edgerton, Jennifer Connelly, Jimmi Simpson, Oakes Fegley. A man is abducted into an alternate version of his life. Amid the mind-bending landscape of lives he could've lived, he embarks on a harrowing journey to get back to his true family and save them from a most terrifying foe: himself.

  4. May 25, 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).

  5. 6 days ago · Dark matter is that invisible glue that keeps stars, dust, and gas together in a galaxy. This mysterious substance makes up the majority of a galaxy's mass and forms the foundation of our Universe's structure. Dark matter is still one of the greatest mysteries of science.

    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 ...

  7. 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.

  8. Jan 28, 2022 · Dark matter makes up over 80% of all matter in the universe, but scientists have never seen it. We only assume it exists because, without it, the behavior of stars, planets and galaxies simply...

  9. May 9, 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...

  10. Jun 21, 2023 · Dark matter is a hypothesized form of matter that does not interact with light or other forms of electromagnetic radiation, but exerts gravitational effects on visible matter, light, and the structure of the universe.

  11. Aug 28, 2006 · Dark energy and dark matter describe proposed solutions to as yet unresolved gravitational phenomena. So far as we know, the two are distinct.
