Presumably small variations in early conditions coupled with trillions of years of gravitational interactions could warp that the universe into a decidedly unspherical shape from the perspective of Yahweh and Vishnu.
After trillions upon trillions upon (you get the picture) of years, the last things around will be humongous black holes with very low temperatures evaporating into the empty coldness and any "early time" variations will be completely smoothed out.
I do not know if the cc is truly constant in such vacuous conditions, so that's where I got my earlier posted notion that anything "could" be possible at very late time/very great distance. I leave it to the Penroses, Steinhardts & Turoks and etc. of this world to sort this near-vacuum state into proper calculable models though...
