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 ...

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 ...

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.

On the other hand, quantum physics leads to a lot of weird and seemingly counterintuitive phenomena, so when physicists like good old John von Neumann point out that entropy in quantum systems ...

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 ...
