In a nutshell Researchers have demonstrated mathematically that quantum systems preserve time-reversal symmetry, meaning ...

In simpler terms, the second law of thermodynamics means that things naturally tend to become more disordered over time.

Researchers from Nagoya University in Japan and the Slovak Academy of Sciences have unveiled new insights into the interplay ...

Physicists have performed a simulation they say sheds new light on an elusive phenomenon that could determine the ultimate ...

But there is at least a certain tension between how quantum theory describes the world and how we think space-time works in Einsteinian relativity. Attempts to resolve this tension have ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

What is quantum ... time. But to understand how things work in the real world, quantum mechanics must be combined with other elements of physics – principally, Albert Einstein’s special theory ...
