Dark matter makes up a large portion of the universe, but we've never seen it. Here's what we know, what it might be, and why it could change everything. More than 80% of the universe's matter is ...

Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't know whether star-free dark matter halos exist. An Diego astrophysicist has calculated the mass below ...

The reason we call dark matter dark isn't because it's some shadowy material. It's because dark matter doesn't interact with light. The difference is subtle, but important. Regular matter can be dark ...

An AI-powered tool can distinguish dark matter's elusive effects from other cosmic phenomena, which could bring us closer to unlocking the secrets of dark matter. Dark matter is the invisible ...

Scientists have long suspected that a see-through substance known as dark matter suffuses the cosmos, keeping the fabric of our universe from tearing. But what exactly dark matter is made of ...

Scientists have just slashed the potential hiding spaces for dark matter particles. The LUX-ZEPLIN, or LZ, experiment has searched for and ruled out the existence of dark matter particles with a ...

Ultrafine dark matter, millions of times lighter than electrons, could flow through the cosmos in waves. We might just have an easy way to check for tiny interactions between this dark matter and ...

Scientists call that dark matter, because it does not interact with light and is invisible. In the 1970s, American astronomers Vera Rubin and W. Kent Ford confirmed dark matter’s existence by ...

You know dark matter, the mysterious stuff that most physicists now believe makes up the bulk of the universe — even though it remains completely undetectable, except for its gravitational ...

A: It is true that we cannot see dark matter directly. The blue color in the image of the El Gordo galaxy cluster (at left) was artificially added to show where the cluster’s dark matter resides.

It is impossible for a telescope to image and far from being completely understood, yet dark matter is everywhere. The deepest mysteries about dark matter relate to its nature and behavior.

This ordinary matter is by far in the minority, and the rest of the universe is 27% dark matter and 68% dark energy. “Dark matter is most of all matter. It’s everywhere, and it’s lurking in ...
