Throughout the twentieth century, physicists have been trying to unify. gravity with the Standard Model (SM). A vague statement about quantum Elko Fields Andrew Lopez Throughout the twentieth century, physicists have been trying to unify gravity with the Standard Model (SM). A vague statement about quantum gravity is that it induces non-locality.
