Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of ...

The challenge of quantum gravity For decades, physicists have struggled to reconcile the principles of quantum mechanics with those of general relativity.

A new perspective on gravity emerges from the work of Ginestra Bianconi, professor of applied mathematics at Queen Mary University of London. Her study, published in Physical Review D, proposes an ...

Famed physicist Stephen Hawking took gravity to its ultimate limits. In doing so, he made a number of significant ...

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 ...

For decades, physicists have struggled to reconcile the principles of quantum mechanics with those of general relativity. While quantum mechanics governs the behaviour of particles at the smallest ...

Several physicists have proposed theories that try to unite quantum mechanics with Einstein’s general theory of relativity.

Famed physicist Stephen Hawking took gravity to its ultimate limits. In doing so, he made a number of significant advancements in our understanding of black holes, cosmology and quantum gravity.
