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

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

A groundbreaking study has challenged centuries of scientific consensus, potentially unravelling our understanding of how light behaves. Research from the Max Planck Institute for Quantum Optics may ...

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

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 ...

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 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 ...

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 ...

Scientists say fragments of energy may be the fundamental building blocks of the universe—not particles and waves.
