Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

From your morning coffee to the road leading to your office and all other things and people you experience in your everyday life are all part of the classical world. This world is governed by the ...

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 ...

Classical physics encompasses the body of theory developed over the past few centuries that describes the behaviour of macroscopic systems. Rooted in Newton’s laws of motion and gravitation, the ...

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 ...

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 ...

Quasiparticles -- long-lived particle-like excitations -- are a cornerstone of quantum physics, with famous examples such as Cooper pairs in superconductivity and, recently, Dirac quasiparticles in ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...
