Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

Physicists have spent a century trying to reconcile the smooth fabric of spacetime in general relativity with the jittery ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

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 ...

Quantum gravity challenges the classical notion of spacetime by positing that the smooth, continuous fabric described by general relativity may arise from more fundamental, non-spatiotemporal entities ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Gravity, a fundamental force we take for granted, might be more mysterious than we ever imagined. A groundbreaking study has emerged, challenging long-held beliefs about gravity and its nature. This ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive ...
