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

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 ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

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.

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 ...

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 ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...
