Dark Matter

A new theory suggests dark matter may have come from quantum bags that got squished together in the early universe.

By entangling the motion and quantum properties of a beryllium crystal, scientists have achieved unprecedented precision for measuring electromagnetic waves.

Dark matter could be even weirder than anyone thought, say cosmologists who are suggesting this mysterious substance could interact with itself in a higher dimensional universe.

Astronomers may not know what dark matter is, but they do know that galaxies are supposed to contain a lot of the shadowy, invisible substance.

A new map of the local universe created with machine learning reveals filaments of dark matter connecting galaxies.

Astronomers are hoping to use the wake of stars to test the existing theories of dark matter.

A hunt for hypothetical axions streaming from Betelgeuse turns up empty but helps physicists set constraints on their properties.

A new study suggests that annihilating dark matter particles may explain the Milky Way center's mysterious glow.

The Hyades — the closest star cluster to our sun — is being stretched by an invisible 'lump,' researchers say.

Scientists are finally figuring out how much dark matter — the almost imperceptible material said to tug on everything, yet emit no light — really weighs.
