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 ...
While general relativity sees space-time as continuous, quantum theory sees the universe as discrete parts that make up a bigger whole. They can't both be true. "Does gravity have to yield?
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 ...
Researchers hope to use these shifting quantum perspectives to make sense of the puzzling nature of gravity. Einstein’s general relativity, which is a classical theory of gravity, says that ...
The quantum version of this 18 th-century classic would involve studying the correlations between two torsion pendula placed close together as they rotate back and forth like massive harmonic ...
