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

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

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

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 ...

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

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

Quantum mechanics forms the bedrock of modern physics, describing the behaviour of matter and energy at the smallest scales. Its counterintuitive concepts, such as wave‐particle duality, superposition ...

In quantum world, particles like photons can behave like particles (localized points) or waves (spreading out, showing interference patterns). The classic double-slit experiment is a good ...

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

Does quantum mechanics really reflect nature in its truest form, or is it just our imprecise way of describing the weird properties of the very small? A famous test that can help answer this question ...
