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

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Add Yahoo as a preferred source to see more of our stories on Google. An artist's concept of multiple types of subatomic particles. (Mark Garlick/Science Photo Library) Forget about turtles; for all ...

The quantum Cheshire cat effect draws its name from the fictional Cheshire Cat in the Alice in Wonderland story. That cat was able to disappear, leaving only its grin behind. Similarly, in a 2013 ...

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

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it. Yet its gravity helps shape galaxies, and that makes ...

The original version of this story appeared in Quanta Magazine. In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She ...

New study reveals how quantum entanglement is transferred in ultrafast photoionisation experiments, offering us insights into how quantum information develops from microscopic to macroscopic scales ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...
