This article claims that Young's famous double-slit experiment — which for a century has been taken as textbook proof that light is both a wave and a particle — might actually be explainable using only particles. The researchers argue that the interference pattern (the bright and dark stripes) does not require waves canceling each other; instead, photons sometimes enter “dark states” where they can’t excite a detector, so it looks like no light is there even though photons passed through. If correct, this would mean wave-particle duality is not a fundamental feature of light, but an inference built from incomplete models. This does not overthrow quantum mechanics, but it challenges the idea that light must have a wave aspect at all — and it could reshape how we interpret measurement, interference, and maybe even the role of the observer in quantum physics.
