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

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

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 ...

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

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 ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

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 ...

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 — ...
