LIVERMORE, Calif. – Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as ...

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 ...

Dynamical friction. The panels depict sparse areas of the universe with dark colour and dense areas with light colour. The upper panels show the density around a galaxy if the galaxy's gravity bends ...

A new study broadens the horizon of knowledge about how matter behaves under extreme conditions and helps to solve some great unknowns about the origin of the universe. An international team of ...

A window into how visible matter emerges from the “nothing” of vacuum has been opened by physicists at the Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) in New York. The ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that particles of matter emerging from energetic subatomic smashups retain a key ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...
