It's one of the most brilliant, controversial and unproven ideas in all of physics: string theory. At the heart of string theory is the thread of an idea that's run through physics for centuries, that ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

"Wonderful, beautiful and unique" is how Gordon Kane describes supersymmetry theory. Kane, a theoretical physicist at the University of Michigan in Ann Arbor, has spent about 30 years working on ...

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 his latest book Nobel Prize winner Steven Weinberg explores how science made the modern world, and where it might take us from here From Quanta Magazine (find original story here). If you're ...

What is light made of: waves or particles? This basic question has fascinated physicists since the early days of science. Quantum mechanics predicts that photons, particles of light, are both ...

In his latest book, the Nobel Prize winner Steven Weinberg explores how science made the modern world, and where it might take us from here. STEVEN WEINBERG: One difference, of course, is that they ...
