Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing ...

The universe has cooked up all sorts of bizarre and beautiful forms of matter, from blazing stars to purring cats, out of just three basic ingredients. Electrons and two types of quarks, dubbed “up” ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

Hypothetical particles called axions have been sought by physicists for decades, as they are the leading candidate for what makes up dark matter. But we may not need new experiments to find exotic ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...

If dark matter particles decay, then scientists could hunt for signs of this process, including X-ray or gamma-ray radiation or even emitted "ghost particle" neutrinos, in vast clusters of galaxies.

"WIMPs are still the leading candidate for dark matter, but billions of dollars of experiments have been done, only getting stronger and stronger upper limits, so alternative scenarios have to be ...
