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

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 ...

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

Photons are particles of light, or waves, or something like that, right? [Mithuna Yoganathan] explains this conundrum in more detail than you probably got in your high school physics class. While ...

Light is a paradox. It is associated with wisdom and knowledge, with the divine. The Enlightenment proposed the light of reason as the guiding path toward truth. We evolved to identify visual patterns ...

Light’s dual nature, manifesting as both wave-like and particle-like behaviour, is a phenomenon known as wave-particle duality and remains one of the most perplexing mysteries in quantum mechanics.

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

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

We’ve all seen recreations of the famous double-slit experiment, which showed that light can behave both as a wave and as a particle. Or rather, it’s likely that what we’ve seen is the results of the ...
