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.
Dark Matter: Created by Blake Crouch. With Joel Edgerton, Jennifer Connelly, Alice Braga, Jimmi Simpson. 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.
Jul 18, 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).
But what is dark matter? One idea is that it could contain "supersymmetric particles" – hypothesized particles that are partners to those already known in the Standard Model. Experiments at the Large Hadron Collider (LHC) may provide more direct clues about dark matter.
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.
Jul 9, 2024 · 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.

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...
Jan 28, 2022 · Dark matter emits no light, and cannot be directly observed, but scientists think that it and dark energy make up most of the mass of the universe.
The invisible form of matter, called dark matter, makes up roughly 30% of the universe’s total mass. Its gravity drives normal matter (gas and dust) to collect and build up into stars, galaxies, and massive galaxy clusters.
The mission will measure the locations and quantities of both normal matter and dark matter in hundreds of millions of galaxies. Throughout cosmic history, dark matter has driven how stars and galaxies formed and evolved.
