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

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

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

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

Physicists from Trinity College Dublin believe new insights into the behavior of light may offer a new means of solving one ...

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 ...

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 ...

Shini introduces the idea of Quantum Mechanics and how it helps us understand light. What is light? That is something that has plagued scientists for centuries. It behaves light a wave... and a ...

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 ...

The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space. The ...

A course offered at the University of Wisconsin has long been connecting seemingly unrelated fields — the sciences and arts — into an interdisciplinary education. Physics 109 — Physics in the Arts — ...
