A Model of Spacetime Dynamics with Embedded Quantum Objects [PDF]

open access: yesReports in Advances of Physical Sciences, 2017
General relativity theory (GRT) tells us that (a) space and time should be viewed as an entity (called spacetime), (b) the spacetime of a world that contains gravitational objects should be viewed as curved, and (c) spacetime is a dynamical object with a
