Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges. Now, ...

A null boundary carries a degenerate signature (0++) metric, which is obtained by taking the pull-back of the four-dimensional line element to the boundary. Credit: Classical and Quantum Gravity (2025 ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

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 ...

Breakthroughs in science often begin with a simple question and years of tireless exploration. From the way tiny molecules slip through microscopic pores to the staggering behavior of matter near ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. When you purchase through links on our ...

Some random article came up on google for me about how there is a new attempt to reconcile both QM and Relativity through some space time dimension field. The point being that wouldn't such a theory ...

"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 ...

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 ...
