• (C) it yields inconsistencies in spatial topology equations, discriminating unnecessarily between the torus and the plane
• (D) it creates the illusion that observable space is curved, when in fact the universe may be Euclidean and planar
• (E) it does not provides sufficient variety in geometrical models to describe all the possible ways in which space may curve
