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 ...

At the quantum scale, systems do not exist in isolation. They interact, exchange information, and become correlated with one ...

Time’s passage is non-negotiable. Its flow marks the progress of our lives, moving clearly in one direction. It is, by nature, asymmetrical. In this way, we perceive it to move like an arrow, ...

If a cup of water spills on the floor, the water can’t unspill—that is, it’s inconceivable that each water molecule would exactly reverse its course to slip back into the cup. To do so would be to ...

(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, ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

Like it or not, time is a fundamental part of life. And over the millennia, scientists have generally regarded time as a one-dimensional thing, an arrow that keeps moving forward, never backward. But ...

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, ...

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.
