Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

(a) QCD factorization of the DVCS amplitude. The perturbatively calculable “hard part” is shown to lowest order in the strong coupling. The nonperturbative “soft part” is described by the universal ...

Despite decades of effort, a theory of quantum gravity is still out of grasp. Now a group of physicists have proposed an experimental test of whether gravity is quantum or not, to settle questions ...
