Neutralino's response to the above quote by Lloyd: "Of course a 2 dimensional surface is not a model of the universe. However, the 3 dimensional surface of a 4 dimensional sphere is a conceivable model of the universe. This surface (called S^3 amongst mathematicians) is topologically equivalent to the surface of a 3-sphere, but we cannot picture what it would look like. Therefore, I used the lower dimensional model to try and emphasize the point that there are models of the universe that have no centre. I hope that this has emphasized it sufficiently."
Dear Neutralino:
There are no three dimensional 'surfaces' - only charges of EM that become more dense as the center of a '3-D' system (electron, for example) is approached.
