Non-trivial spacetime shape provides topological protection against quantum fluctuations that should make the constant enormous.

A new experimental design suggests that scientists could exchange energy between laser beams and gravitational waves to prove that gravity is made of tiny individual particles called gravitons.

Researchers develop a unified guide to identify tiny distortions in space and time, linking quantum physics and gravity theories with measurable signals in current tools.

A new approach uses modern quantum tools and gravitational waves to spot single gravitons, potentially uniting quantum physics with Einstein's gravity theory and opening experiments on quantum gravity.

New research introduces quantum geodesics, offering a way to test theories uniting quantum physics and general relativity through observable deviations in space-time trajectories.

Researchers propose a quantum gravity theory compatible with particle physics, advancing our understanding of fundamental forces.
