From the time of Dante [Alighieri], when you have the Ptolemaic universe, you had God on the outside like a hypersphere, and then in the center you have the Earth, all the seven heavens and layers, and then you have the Mount of Purgatory and Hell right in the center, and here's Satan flapping his wings and he keeps making the lake of Cocytus ice so you can't get out. So, again, where Heaven and Hell are, who the hell knows that now?
