The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

Physicists have taken quantum strangeness to an extraordinary new level by measuring light across 37 dimensions. Their groundbreaking experiment pushes quantum mechanics beyond classical expectations, ...

Albert Einstein and Niels Bohr had an ongoing rivalry about the true nature of quantum mechanics, and came up with a thought ...

An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, ...

Physicists using near-absolute-zero detectors have reached unprecedented sensitivity in the hunt for light dark matter. A groundbreaking scientific project known as QROCODILE, led by the University of ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

"These single atoms are like the smallest slits you could possibly build." For over 100 years, quantum physics has taught us that light is both a wave and a particle. Now, researchers at the ...

TL;DR: This experiment may not revolutionize telecommunications, but it highlights how accessible these concepts have become outside traditional research labs. Using nothing more than an iPad, a solar ...

Andrea Gallo Rosso is a member of the ALPHA collaboration. He receives funding from the Swedish Research Council. Several experiments have aimed to unveil what it’s made of, but despite decades of ...
