If ever spotted in the emptiness of space, according to theoretical physicist Eugeny Babichev of the University of ...

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

The speed of light is one of the most fundamental constants in physics, yet it has never been directly measured in one direction. Instead, scientists rely on assumptions built into how time and ...

Shaped quantum light is turning ordinary photons into powerful tools for the future of technology.

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

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

While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...
