Yes, classically things would be very divergent on such a big scale. Though once we get to those scales, I suppose we need to turn our Bizarro-Newtonian-Gravity into some Bizarro-General-Relativity. Without thinking too hard about what all that means... I'd guess all the extra gravity would give us a 'Big Crunch' pretty quickly. Or, at least something close to a crunch... since as the universe got smaller, gravity would get weaker and weaker.A Random Player wrote:Not necessarily.. The universe is isotropic (I think) and infinite, so one will be pulled from all sides the same.. But how would the universe know which "side" of the infinity has more mass?

On that topic, since spacetime would curve *more* the further away you are from a mass... every object would have an event horizon if you go out far enough.

Thank goodness this is just a 2D simulation!
