>>2280595you are correct but its actually a Möbius sphere. Much like a Möbius strip requires 3 euclidian spatial dimensions to render, a Möbius sphere requres 4 dimensions to render.
Every possible vector (from every possible point) on the surface of the sphere travels around the surface (like a ball of yarn kinda) before reaching its starting point, but on the "other side" of the sphere. I put "other side" in quotes, because each vector wrapping around creates a DIFFERENT "other side" of the surface of the sphere, so there is no "inside" of the surface like on a typical 3d sphere.
this "4th dimension" of the Möbius sphere is what we experience as "time"
