This is the so-called entropy catastrophe. This critical temperature, where a superheated solid and a liquid have the same entropy, is around three times the melting temperature. Gold has a melting ...

Heating that lasted only trillionths of a second raised a gold sample’s temperature to 19,000 K without melting it, a study ...

Instead of the big bang, some physicists have suggested that our universe may have come from a big bounce following another ...

Evolution cannot explain biological complexity without violating some fundamental laws of nature, specifically, the Second Law of Thermodynamics. If you recall, we mentioned the Second Law of Thermody ...

Time is one of the most intriguing concepts in physics, and yet, it's something that we often take for granted. But what if the way we experience time moving only forward defies the very laws of ...

The second law of thermodynamics demands that if we want to make a clock more precise – thereby reducing the disorder, or ...

In the strange, often unintuitive world of quantum physics, one mystery has stood out for decades: Can quantum entanglement be manipulated in a reversible way, like energy in a perfect heat engine?

A new study shows entanglement can be reversed—if you plug in a quantum battery. The finding rewrites the rules of the quantum world.

Second, he said, there might be “an arrow in time that describes this increasing complexity,” similar to the way the second law of thermodynamics, which describes the increase in entropy, is ...
