A fundamental rule that determines the fate of the universe The second law of thermodynamics means hot things always cool unless you do something to stop them. It expresses a fundamental and simple ...

One of the most important principles of physics, that disorder, or entropy, always increases, has been shown to be untrue. This result has profound consequences for any chemical or physical process ...

Black holes are intriguing astronomical objects that have a gravitational pull so strong that it prevents any object and even light from escaping. While black holes have been the topic of numerous ...

One of the most fundamental rules of physics, the second law of thermodynamics, has for the first time been shown not to hold for microscopic systems. The demonstration, by chemical physicists in ...
