A model of the cyclic universe suggests that dark matter could be a population of black holes predating the Big Bang.

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it. Yet its gravity helps shape galaxies, and that makes ...

Dark matter has been thought to be cold and collisionless, meaning its particles don't interact with each other. The new study, however, challenges this assumption.

A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar ...

Dark matter is supposed to be everywhere, threaded through the Milky Way and outnumbering ordinary matter by a wide margin.

A tiny object half a universe away, a scar in a stream of stars circling the Milky Way, and an unusual star cluster in a ...

Invisible dark matter particles may regularly pass through our bodies, and dozens to thousands of these particles may be colliding with atoms inside us every year, according to a new calculation.

The SuperCDMS is chilled to right around absolute zero, and its detectors are primed to hunt dark matter particles.

Learn how a two-state model of dark matter could explain why gamma-ray signals appear in some galaxies but not others.

A new study suggests that failing to detect dark matter signals in some galaxies may not contradict evidence seen in our own.
