If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...

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

If spacetime is classical, it should undergo random fluctuations, which could in turn change the mass of objects by tiny amounts over time. One experiment the team suggests is that measuring an object ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

The Matter of Everything tells the history of physics through experiments. Any book about the history of science for a general audience will, of necessity, be something of a distortion. The question ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

Lab experiments around the globe that are gearing up to recreate the mysterious phase of matter found in the early universe could also produce the world's strongest electromagnetic fields, according ...
