Spacetime Curvature Inside a Stationary Volume Completely Enclosed by a Near-Light-Speed Energy Shell: The Börekci Energy Field Apparatus, the Redesigned Börekci Metric and Antimatter Production
General relativity describes gravity not as a force but as the curvature of spacetime geometry. In this framework an object does not attract the objects around it; it curves the spacetime around it, and objects moving within that curvature follow their geodesics.
