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

Dark matter is believed to make up a large fraction of the matter in the universe, yet its true nature remains unknown. Most ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

The vast majority of matter is dark – invisible until it is detected only through its gravitational effects. The newly discovered object could be a clump of dark matter, or it could also be a compact, ...

This may be remembered as one of the more important physics images of this generation. Credit: Tomonori Totani, The University of Tokyo Physicists from Japan's University of Tokyo have published a new ...

We may have seen the first hints of strange stars powered by dark matter. These so-called dark stars could explain several of the most mysterious objects in the universe, while also giving us hints ...

Cosmic web Created using data from the JWST, this map shows how dark matter acts as the hidden framework on which visible galaxies are built. The overlaid contours mark regions of equal dark-matter ...

Physicists call it “ dark matter, ” a substance they describe as the cosmic glue, the scaffolding, a web that uses gravity to corral, shape and hold together stars, planets and galaxies. Yet nobody ...
