Abstract Gravity whose nature is fundamental to the understanding of solar system, galaxies and the structure and evolution of the Universe, is theorized by the assumption of curved spacetime, according to Einstein, s general theory of relativity (EGR). Particles which experience gravity only, move on curved spacetime along straight lines (geodesics). The geodesics are determined by curvedspacetime metric. In the last year, I proposed the mirrored version of EGR, the flat-spacetime general relativity (FGR), in which particles move along curved lines on flat spacetime. This puts gravitational study back to the traditional Lagrangian formulation. The Lagragian on flat spacetime is simply taken to be the curved spacetime metric of EGR. In fact, all acclaimed accurate verification of general relativity is the verification of FGR, because relativists when confronting GR to observational data, calculate time, distance, or angle by directly using the coordinates in Schwarzschild solution or in post Newtonian formulation. For example, two famous tests of general relativity are about angles. All mainstream textbooks and papers calculate the angles by directly using the coordinate φ. However, only when spacetime is flat does there exist one coordinate system which has direct meaning of time, distance, angle, and vice verse. This is the famous Riemann theorem when he pioneered the concept of curved space. According to the theorem, all coordinates on a curved space are merely parameters.
