By definition, according to the laws of motion, starting from a single point, and every point moving by the amount for the same amount of time, would give you a sphere. Not a loaf of raisin bread. -Agreed

One can work Hubble constants backward and imagine a point or singularity as Hawking once did, but as I said before mapping the universe has resulted in huge bubble areas, great walls or galaxies, and although it is overall uniform, in localized areas it is not. I don't know of an author who has described it as a perfect sphere.
