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 ...

Arkani-Hamed therefore suspects that the usual notion of quantum particles moving and interacting in space-time is an approximation of deeper, more abstract concepts, which, if found, could serve ...

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.

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 ...

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.

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 ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go to the ends of space and time to find a fix.

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.
