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 ...

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

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 ...

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.

Entropy always increases, but in quantum systems, traditional entropy measures seem constant. TU Wien researchers resolved this paradox by considering Shannon entropy, which accounts for the ...

Protons are far from simple particles — they are swirling cauldrons of quarks, gluons, and quantum entanglement. Scientists ...

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 ...

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 ...

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

"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.

This week, astronomers reported the discovery of a super-Earth potentially capable of sustaining life, occupying an eccentric orbit around its star that oscillates in and out of the habitable zone.
