Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...

“In both quantum gravity and classical gravity, spacetime must be undergoing violent and random fluctuations all around us, but on a scale which we haven’t yet been able to detect,” said Zach ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.

A new computational simulation of the early universe has revealed a fundamental, unbreakable geometric limit to the fabric of spacetime, dubbed the "Metric Wall." Discovered by independent physics ...

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

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 ...

Quantum gravity remains one of the foremost challenges in theoretical physics, seeking to reconcile the principles of quantum mechanics with the geometric understanding of spacetime envisaged by ...

There is no question that quantum theory is correct. It’s been proven over and over, both in the lab and through practical achievement. But the question remains: is it always correct? Quantum ...

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