Two ghostlike particles, neutrinos and photons, are emerging as unlikely combatants in a quiet revolution in physics. New ...

A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a ...

Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

A new study takes the GHZ paradox, which describes how quantum theory can't be described by local realistic descriptions, to ...

Using the Super Proton Synchrotron, the team created beams of electron-positron pairs and passed them through a meter-long region of plasma. This setup served as a scaled laboratory version of a ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Physicists are learning to treat light not as an untouchable beam that simply passes through matter, but as something that can be bent, cloaked, and sculpted at scales smaller than a single wavelength ...

Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported the first ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

This episode of the Physics World Weekly podcast features Alex May, whose research explores the intersection of quantum ...
