The '''curvature of spacetime''' refers to this. It gives rise to the "fictitious forces" that are perceived as gravity under [[General theory of relativity|General Relativity]]. The Einstein Field Equations explain how that curvature arises from the presence of massive objects like the Earth or the Sun. Analyzing the resultant gravitational fictitious force arising from massive objects obtains the same result as Newton's law of gravity for non-relativistic objects. | The '''curvature of spacetime''' refers to this.
