Concerning the expanding Universe, a new truth can also be assumed that the entirety of the Universe is in the shape of a hypersphere, a fourth-dimensional sphere. This can be proven by logic: If a second dimensional universe looks like a flat plane without up nor down, it has to meet itself somewhere. This creates an undeniable sphere. So one can then assume that since a 3D Universe  looks like a prism, with access to side to side, up and down, it all has to connect like the second dimension, making it a round forth dimensional figure, a hypersphere.
