General relativity -- Conceptual question Hello, I have a conceptual question. May be I am sounding a little bit idiotic, so apologize for that. I believe, there is no harming in knowing that I am wrong. Einstein's general theory of relativity describes gravity as a geometry of space time. On a macroscopic scale, in the space time continuum if we have the sun, stars and other objects placed on space time, it causes a dent (in a very layman's language), or a space time curvature which causes Earth or other celestial objects to move around. For that we have field equations and other things to understand more precisely. Now, we take another scenario. Say, for example, this world where we live in and we have other terrestrial objects like chair, car, buildings, mountains. Those things also causes a curvature based on the mass and the position. My question is that: can we in the same way that we describe the curvature of space time in macroscopic scale (sun and stars), describe the curvatures of terrestrial objects (like mountains and hills)? Are the equations of macroscopic scale still applicable in microscopic scale? Thanks.
