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

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in ...

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

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 ...

In the end, the Universe becomes a place where gravity and quantum physics slowly turn all mass into faint streams of particles.

TU Wien researchers have uncovered a quantum twist to the paths particles take through spacetime — one that could finally ...

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 ...

The study of higher dimensional gravity theories represents a vibrant and innovative field in modern theoretical physics. At its core, this research seeks to extend the familiar four-dimensional ...

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 ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

How to build a particle collider the size of the solar system. To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could ...
