I have a very faint idea of General Relativity.. hence this question. I think that according to General Relativity, the shortest distance between two points on this earth is along a curved path, which is the curvature of the earth [or sorta.. parallel to it]. Hence, i assumed that when on earth, we measure an area of the land, and we treat it as a rectangle, we are not making an approximation, but that, in fact is the actual area we calculate on this earth.(adsbygoogle = window.adsbygoogle || []).push({});

so, is it true that if we are to measure the surface area of the earth while being on the earth, we will measure it to be [itex]4\pi^2 R_e^2[/itex] rather than [itex]4\pi R_e^2[/itex]??
