Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

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

A team of physicists has uncovered a surprising new way to explore one of science's greatest challenges: uniting the two fundamental theories that explain how our universe works—Einstein's theory of ...

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 ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

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 ...

In a new study published in Physical Review D, Professor Ginestra Bianconi, Professor of Applied Mathematics at Queen Mary University of London, proposes a new framework that could revolutionize our ...

Quantum gravity is a research area in theoretical physics that seeks a consistent, predictive framework unifying general relativity with quantum mechanics by quantizing the gravitational field. It ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

Physicist Brian Cox has rarely been shy about his enthusiasm for big, difficult ideas, but his reaction to a recent quantum gravity paper stands out even by his standards. He has described the work as ...
