Is gravity a fictitious force?
Is gravity a fictitious force? Under General Relativity, the force of gravity is replaced by distortions in space itself. Objects move following the curvature of space. At low energies, in an inertial reference frame, that works out to move exactly the same way as under Newtonian gravity. Thus, Newtonian gravity is a “fictitious” force. Why […]
