Everything in space—from Earth and the sun to black holes—accounts for just 15% of all matter in the universe. The rest of ...

But axions were pushed aside as the WIMPs hypothesis gained more steam. Back-of-the-envelope calculations showed that the ...

Inspired by superconductivity, a strange new theory that seeks to explain dark matter might explain dark energy, too ...

Dark matter remains effectively invisible by not interacting with light, but its interaction with gravity has helped to shape galactic structures. "This is the missing piece we've been looking for ...

The earliest galaxies are thought to have formed as the gravitational pull of dark matter, which has been impossible to study directly, slowly drew in enough hydrogen and helium to ignite stars.

As such, researchers suspected galaxies might only form if dark matter was involved. However, in 2018, astronomers discovered one large galaxy, ...

Known for its large mass despite emitting very little light, Segue 1 is traditionally viewed as a prime candidate for ...

Dark matter is a hypothetical substance that is believed to comprise about 85% of the matter in the universe. Its gravitational influence prevents large objects such as galaxies from flying apart as ...

Dark matter may be a quantum mechanical wave that literally holds galaxies together. Quantum mechanics is our best theory of the fundamental nature of reality, but it's usually only ...

Dark matter remains effectively invisible by not interacting with light, but its interaction with gravity has helped to shape galactic structures. "This is the missing piece we've been looking for ...

A composite of Stephan’s Quintet, a visual grouping of five galaxies, constructed from almost 1,000 separate image files from the James Webb Space Telescope. UCLA astrophysicists believe if cold ...
