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

For more than a century, the double-slit experiment has been the sharpest test of what reality is made of, and of whether ...

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

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

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

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew. When you purchase through links on our site, we may earn an ...

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 ...

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 ...

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 ...
