It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...
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 close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

The Universe Could Be Simple – We Might Be What Makes It Complicated, Suggests New Quantum Gravity Paper Prof Brian Cox Calls “Exhilarating”
Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

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 ...
Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...
A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...
(via PBS Space Time) Black holes are inevitable predictions of general relativity—our best theory of space, time and gravity. But they clash in multiple ways with quantum mechanics, our equally ...

Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...
We recall some of the obstacles which arise when one tries to reconcile the general theory of relativity with quantum theory. We consider the possibility that gravitation theories which include ...
