An illustration conveying the idea of a space-based quantum internet, which would seem, like the hypothetical particle of a tachyon, to outpace light. An illustration ...

Quick, pick a side: Is light a wave or a particle? This question is best known for its power to set crowds of undergraduates a-tittering. But it’s more than a pop science brain-teaser. Scott Holmstrom ...

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 ...

Ever since Democritus – a Greek philosopher who lived between the 5th and 4th century's BCE – argued that all of existence was made up of tiny indivisible atoms, scientists have been speculating as to ...

Is light made of waves, or particles? This fundamental question has dogged scientists for decades, because light seems to be both. However, until now, experiments have revealed light to act either ...

A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in ...

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 ...

An extremely rare particle measurement from the world's largest atom smasher could cast doubt on a popular theory about the fundamental building blocks of the universe, including dark matter.

In physics, particles are small localized objects with physical characteristics like mass or volume. From those humble ingredients, our virtually limitless universe is built. The concept, presented in ...
