The speed of light is one of the most fundamental constants in physics, yet it has never been directly measured in one ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

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 ...

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 ...

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 ...

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

A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, ...

Can we turn back time? Ask a savvy physicist, and the answer will be “it depends.” Schemes for retrograde time travel abound but usually involve irreconcilable paradoxes and rely on outlandish ...

There's an episode of Star Trek: The Next Generation in which John de Lancie's nearly-omnipotent alien character "Q" is stripped of his powers and banished to the Enterprise as a human because fans of ...

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 — ...
