Researchers have demonstrated that a nanoparticle of 7,000 sodium atoms can act as a wave, creating a record-setting ...

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.

Scientists have long grappled with a fundamental question: what exactly is light? Is it a wave, flowing like ripples across water, or is it made up of tiny particles, like miniature paintballs zipping ...
