“The main question is if there can be any space without space, although this sounds absurd, for it is evident that there can be no space without space. However, if there can be no space without space, how can there be the curvature of space if there is no space? Then, we may answer that there is space and engage in circular reasoning. On a superficial level, some “obvious axioms” lead us to accept that there is space as it is without questioning how that is, how it is possible, and what creates this space. Then, we may answer that, based on laws of physics, nature works in such ways and that there are four main forces, and that based on all our knowledge and theories confirmed by experiments, we conclude and state, based on a “fact,” that there is a curvature of space.”
