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 ...
Several physicists have proposed theories that try to unite quantum mechanics with Einstein’s general theory of relativity.
It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...
Einstein's theory of general relativity is our best description of the universe at large scales, but a new observation that reports a "glitch" in gravity around ancient structures could force it to be ...
