Scientists at the University of Illinois Urbana-Champaign have confirmed the existence of a massless particle, long theorized ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists announced on Wednesday that they have found no evidence for the hypothetical “sterile neutrino,” an extra version of ...

Several massive multimillion dollar experiments should soon reveal more about the nature of these ghostly particles ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

The hypothetical faster-than-light particle known as the tachyon may marry with the special theory of relativity, according to a team of physicists, making its existence more plausible. Tachyons are a ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it's more difficult. This is something physicists from Poland and the UK are well aware of. To ...

Jason Bono was one of the researchers behind a major scientific moment — when tiny particles unexpectedly unraveled one of the most important and successful theories in physics. Bono, who earned his ...

In the quest to unravel the mysteries of the universe, physicists are revisiting a 150-year-old theory that could illuminate why matter prevails over antimatter. This knot hypothesis, originally ...
