How it works: the wave in the foreground is an illustration of the phase of an out-of-equilibrium Bose-Einstein condensate in a 1D cavity, which belongs to the Kardar-Parisi-Zhang universality class.

The text is now best known for introducing “Pascal’s Law” or “Principle,” that any change of pressure in an enclosed incompressible fluid (like water) is transmitted equally to all points within the ...

The laws of physics do not exist, a theoretical physicist named Sankar Das Sarma argues in a new column published by New Scientist. While we define the laws as the "ultimate laws" of our universe, ...

The dominant view in physics is simple: the laws of nature are fixed. Gravity pulls as it always has; quantum probabilities collapse with the same stubborn indifference today as billions of years ago.

"In the past, entropy was lower; the future is where entropy is higher." However, quantum physics encounters a problem here: the mathematician and physicist John von Neumann was able to show: ...

A University of Portsmouth physicist has explored whether a new law of physics could support the much-debated theory that we are simply characters in an advanced virtual world. The simulated universe ...

The second law of thermodynamics demands that the entropy of any closed macroscopic system should never decrease. The laws of physics naturally drive systems towards states of increasing disorder and ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or two to tell you about fascinating ideas from their corner of the universe.
