New research shows that the second law of thermodynamics, which states entropy increases over time, also applies to closed ...

The universe is getting more disordered, entropy is growing -- this is the second law of thermodynamics. But according to quantum theory, entropy should actually stay the same. Scientists took a ...

For over a century, the Maxwell’s Demon paradox has haunted physics. This thought experiment suggests that a tiny, ...

An international collaboration led by Nagoya University in Japan sheds new light on the relationship between quantum theory ...

The grandfather paradox is just one of the thorny logical problems that arise with the concept of time travel. But one physicist says he has resolved them.

Vanderbilt University physicist Lorenzo Gavassino isn't so sure this is as big an obstacle as time-traveler pessimists have ...

"Entropy is usually associated with uncertainty ... Ben Turner is a U.K. based staff writer at Live Science. He covers physics and astronomy, among other topics like tech and climate change.

Professor Brian Cox explains the concept of entropy and the arrow of time ... This clip is useful for students of Physics or Chemistry. It can help explain why travelling backwards in time ...

At first glance, however, quantum physics does not really seem to adhere to this rule: Mathematically speaking, entropy in quantum systems always remains the same. A research team at TU Wien has ...
