Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...

Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the ...

Ah, dark matter. Creator of the universe, sculptor of galaxies, great brewer of coffee (probably). There seems to be nothing it can’t do, or isn’t responsible for, but there’s just one problem: Where ...

In A Nutshell When two different types of cosmic strings become linked in the early universe, they form stable knots that ...

The Department of Energy’s Fermi National Accelerator Laboratory near Chicago. If accurate, it’s a sign that the theories forming the foundation of modern particle physics don’t tell the whole story.

Scientists have made a particle physics discovery that they say could mean nothing less than the upheaval of our entire model of the building blocks of the universe—if their results can be ...

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 ...

From its resting place outside Chicago, Illinois, a long-defunct experiment is threatening to throw the field of elementary particles off balance. Physicists have toiled for ten years to squeeze a ...

An extremely rare particle measurement from the world's largest atom smasher could cast doubt on a popular theory about the fundamental building blocks of the universe, including dark matter.

"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 ...
