"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Tiny 3D-printed “light cages” are giving researchers a new way to catch and hold individual particles of light on a chip, a ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

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

Spencer Axani, assistant professor in the Department of Physics and Astronomy, is the inventor of CosmicWatch, a portable, ...

Researchers replicated the classic double slit experiment using lasers, but their slits are in time not space. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...
