Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

A controversial prediction about black holes and the expansion force of the universe could explain a cosmology mystery ...

Black holes are eaters of all things, even radiation. A new study published in Physical Review Letters suggests that black holes might spew dark energy—and that they could help explain an intriguing ...

Located in China, Juno is a 17-country collaboration that will try to detect neutrinos and antineutrinos to learn more about their mass.

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 ...

The universe is full of different types of radiation and particles that can be observed on Earth, including photons in the entire range of the electromagnetic spectrum, neutrinos and cosmic rays. A ...

Two enormous telescopes are currently being constructed deep beneath the Mediterranean Sea, off the coasts of France and Italy, with the ambitious goal of detecting one of the universe’s most ...

The most energetic cosmic neutrino, or "ghost particle," ever recorded may be the remnants of a nearby black hole explosion.

“The mass and the antiparticle nature of neutrinos can be studied by measuring the radioactive beta and double-beta decays of atomic nuclei,” Ruotsalainen said. “There are likely some tens of suitable ...
