Wave-particle duality is a fundamental fact of the Universe. But we don’t see many objects moving around as waves. This is why it hurts when a golf ball hits you on the head: you and the golf ball are ...

Now that LIGO has detected their first gravitational wave signal, the part of Einstein's theory that predicts that the fabric of space itself should have ripples and waves in it has been confirmed.

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

The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you’ll produce an interference pattern because the particles ...

Quantum objects are notoriously shifty. Take the photon, for example. The quantum of light can act as a particle one moment, following a well-defined path like a tiny projectile, and a wave the next, ...

Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has demonstrated that two peculiar features of the quantum world previously considered ...

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 ...

For the first time, wave-particle duality has been observed in a biomolecule. The team of physicists at the University of Vienna in Austria have also observed wave-like behaviour in the most massive ...

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 ...
