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

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

God does not play dice with the universe,” Albert Einstein famously declared in 1927, sparking one of the most enduring ...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed.

The concept of wave-particle duality ascribes two seemingly contradictory traits to a single object. Wave–particle duality is a concept in particle physics that ascribes two seemingly contradictory ...

For the first time, wave-particle duality has been observed in a biomolecule. The team of physicists at the University of Vienna in Austria have also observed wave-like behaviour in the most massive ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave ...

Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has demonstrated that two peculiar features of the quantum world previously considered ...

Photon duality remains a paradox because the photon is regarded as a simple, unitary object in space. Equally bad, massless radiation is interpreted via concepts drawn from mass-based physics. The ...

The inherent contradiction in the way energy behaves. At the turn of the 20th century, it was believed that light was electromagnetic waves and electrons were particles. By the 1930s, it was ...
