is a quantum field theory of gravity. Alone of the four forces, gravity has no particles attached to it, and is instead explained by Einstein’s general theory of relativity as the warping of ...

From the mid-1980s, string theory set up a possible framework to approach quantum gravity using a 'top-down' approach. The effective field theory approach to strong forces drove the development of ...
