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

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two ...

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

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

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

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

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 ...

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 ...
