General relativity tested in space

Fundamental physics is at a crucial turning point thanks to recent advances in experimental tests conducted in space. General relativity, a revolutionary theory concerning the curvature of space-time and gravity, is today subject to unprecedented validations via satellites and sophisticated space experiments. The deployment of measurement tools such as ultra-precise atomic clocks in orbit and … Read more

Quantum mechanics and general relativity: a conflict to resolve

La mécanique quantique et la relativité générale : un conflit à résoudre

IN BRIEF Quantum mechanics and general relativity: two major theories of physics. Mathematical incompatibility between the two theories. Problem of unifying gravity and quantum mechanics. General relativity describes gravitation at large scales. Quantum mechanics operates at the subatomic scale. The challenges of a unified theory within the context of the universe. The necessity to reconcile … Read more
