Orbits of electrons around nucleus can never exist because it can lose energy as charges accelerate so there is never orbits of electrons. Why can't we treat gravity as forces in similar fashion.. as something that doesn't really exist. My point is. General Relativity and spacetime curvature is our reality just like electrons using Schroedinger Equation is our reality. Hence why should we even treat classical space as valid or legitimate. Can't we treat classical space like same category of orbits of electrons which is fiction? Because if you assume classical space.. you assume force of gravity which never existed at all because for example black holes can't be modeled as gravity being a force. So you can't say space is classical limit of spacetime curvature.. in the same way you can't say the orbits of electrons is a classical limit of schroedinger equation.
