EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

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 ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

The concept of time has troubled philosophers and physicists for thousands of years, and the advent of quantum mechanics has not simplified the ...

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...
