Where does time really come from? I am often asked this question after acquaintances or friends of friends learn that I am a physics reporter. There is not a set answer – but to better understand it, ...

Time has an arrow: It only ever seems to move in one direction. The future is always unknown to us, while the past forever remains locked and inaccessible. And yet, the vast majority of the laws of ...

There’s a lot we don’t understand about quantum systems. But over the past century, physicists have found ways to exploit the many oddities of quantum mechanics to their liking—including a new ...

The arrow of time is a staple of human perception. Every second of every minute of every hour of every day, you live it. If you spill a drink, you can’t reverse time and pull the liquid back into the ...

(via Big Think) Dr. Robert Hazen, staff scientist at the Earth and Planets Laboratory of Carnegie Science in Washington, DC, thinks that a single arrow of time may be too limiting. A second arrow, ...

A solution for temporal asymmetry -- or entropy production -- in thermodynamics has been developed to further our understanding of the behavior of biological systems, machine learning, and AI tools.
