A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL ...

Add Yahoo as a preferred source to see more of our stories on Google. A illustration shows a quantum experiment investigating gravity on a tiny scale. Scientists have determined a way to measure ...

“A theory that coherently describes all fundamental forces of nature is often called the Theory of Everything,” Aalto University postdoctoral researcher Mikko Partanen said. It has been the physicists ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...

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 ...

As far as we know, our physical world is governed by four fundamental forces: electromagnetism, weak and strong nuclear forces, and gravity. Apart from playing with bar magnets or marveling at the ...

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

"By understanding quantum gravity, we could solve some of the mysteries of our universe — like how it began, what happens inside black holes, or uniting all forces into one big theory." When you ...

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 ...

The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a ...
