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.
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.
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).
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!
Jun 3, 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.

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.
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.
May 9, 2018 · What Is Dark Matter? An elusive substance that permeates the universe exerts many detectable gravitational influences yet eludes direct detection. By. Lisa Randall. Illustration by Chris Gash.
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.
Dark Matter Facts. Dark matter makes up about 85 percent of the total matter in the universe, accounting for more than five times as much as all ordinary matter. Dark matter played an important role in the formation of galaxies.
