Classical physics encompasses the principles that govern macroscopic bodies, fields and continua in regimes where quantum and relativistic effects may be neglected. At its foundation lie Newton’s laws ...

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 ...

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 ...

For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by ...

Explore 25 science experiments that defied the laws of physics, revealing mind-bending phenomena that challenge intuition.

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 ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...
