A growing body of theoretical and experimental work in physics is converging on a striking possibility: time, the dimension humans experience as a constant forward flow, may not be a fundamental ...

Gravitational waves may leave a permanent timing gap in light, revealing how gravity preserves information through a memory ...

Add Yahoo as a preferred source to see more of our stories on Google. New physics research links quantum collapse models to gravity and finds tiny limits on clock precision. (CREDIT: AI-generated ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." When you purchase through links on our site, we may earn an affiliate ...

Time feels like the most basic feature of reality. Seconds tick, days pass, and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
