Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

Electron–proton collisions Study reveals importance of entanglement entropy. (Courtesy: Kevin Coughlin/Brookhaven National Laboratory) An international team of physicists has used the principle of ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...
