We are still too far from the true definition of space and a true definition of fact. To prove that there is a curvature of space, we must undeniably prove and show that we know and understand what space is and that we know and understand what a fact is philosophically, linguistically, and physically. Consequently, we may say we have considered and know all this, but the “fact” remains the “fact.” It is not whether we say we understand all this and have considered all that but if we have genuinely and undeniably proved and understood what we declare.
