A team of scientists has replicated one of Thomas Edison's early experiments from his quest to make the lightbulb, but with ...

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 ...

In a mind-warping milestone experiment, scientists have been able to manipulate small numbers of individual photons of light, opening doors for the development of quantum technologies. This research, ...

In the strange corner of modern physics where spacetime itself becomes the engine, the old rule that nothing can outrun light ...

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 ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

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 ...

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 ...

A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No vacant rooms means there’s no choice but to stay put.
