A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity ...

The new framework — or "recipe" for gravity, if you will — takes the metric of spacetime from general relativity, which describes the geometry of space and time based on distances and ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Illustration of the theory used to model quantum gravity: The lattice simulates a curved space-time – near the boundary, the lattice is denser due to the curvature.

What if you’ve already seen fragments of the future - without realizing it? In this thought experiment grounded in Einstein’s relativity, we unpack how a simple diagram changes our entire ...

Albert Einstein 's theory of general relativity —which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

In 2019 Rovelli published a paper with Marios Christodoulou of the Institute for Quantum Optics and Quantum Information Vienna (IQOQI) arguing that if gravity were indeed caused by deformations of ...

Instead of curving space-time, gravity in their model is mediated by four interrelated fields, with each one similar to the field that governs electromagnetism.
