A new study argues that dark matter and dark energy might be illusions caused by the universe’s forces fading over time. For many years, scientists have thought that dark matter and dark energy make ...

Dark matter, the substance that makes up about 27% of the universe, could potentially be detected as a red or blue light ...

The object was detected by observing how its gravity distorts light behind it. Astronomers have discovered an extremely faint ...

For decades, astronomers have believed that dark matter and dark energy make up most of the universe. However, a new study ...

The story begins with the black hole information paradox. According to relativity, anything that falls into a black hole is ...

When trying to identify the nature of dark matter, sometimes it’s the things it doesn’t do that tell us the most, like turning the center of the Earth liquid. A new study has shown that if some models ...

Evolving dark matter may explain cosmic acceleration. Observations support a mixed model. For years, a stubborn puzzle has sat at the center of the standard cosmological model. The evidence clearly ...

We have not been able to detect dark matter yet, even though there are many aspects of the universe that suggest the existence of invisible matter. In one new theory, it is possible that dark matter ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

The Bullet Cluster as seen by the James Webb Space Telescope (JWST) consists of a larger cluster of galaxies (left) and a smaller cluster (right). The hot gas seen by the Chandra X-ray Observatory is ...

Astronomers have found over 5,000 exoplanets, and now scientists think these distant worlds could unlock one of the universe’s greatest mysteries: dark matter. A new study suggests that Jupiter-like ...

Ask most astronomers, and they'll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...
