I agree. We also have the additional experimental fact that we have never observed anything that indicates an edge of spacetime with finite curvature.zonde said:So if the reasoning can't be restricted to math only it's sort of philosophy
If the spacetime didn’t end then the geodesic could be further extended. Anyway, consider the standard KS coordinates covering the maximally extended Schwarzschild vacuum. The singularity in region II is an edge of the manifold.zonde said:I certainly do not understand that "spacetime ends" option. As I see this it's geodesics that end there not spacetime.

That option definitely is considered. That is one of the drivers of work on quantum gravity.zonde said:I don't understand why option "particular solution has somewhere sneaked in unphysical assumption" is not considered
