Researchers say they may have taken a significant step toward explaining the origin of gravity. SHARJAH, EMIRATE OF ...

Einstein’s theory of general relativity describes gravity as the curvature of space and time caused by matter and energy.

Recent research shows that gravity and quantum information are deeply connected and that the shape of spacetime can be traced back to the way information is stored in quantum fields. Einstein's theory ...

Wormhole time travel is mathematically valid under general relativity, but exotic matter, stability, and quantum gravity gaps ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

A recent study has investigated teleparallel gravity and its potential to resolve tension surrounding the expansion of the universe in a way that general relativity can't. In the early 20th century, ...

The odds of the bet Jonathan Oppenheim made in 2023 are generous, even at 5000 to 1. But if he wins, it could transform our view of the universe. The physicist is wagering that space-time, and ...

Scientists have spotted the first hints that Einstein's formulation of gravity operates in the quantum realm.

General relativity describes gravity not as a force but as the curvature of spacetime produced by mass and energy. Matter tells spacetime how to curve, and this curved geometry guides the motion of ...

An explanation of two key reasons why quantum gravity remains unsolved: the mathematical incompatibility between quantum ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...
