QUOTE : Ever since I was a child, I've been hearing physicists insist that nothing can travel faster than light. That it would break the universe somehow. Something to do with causality ... But it's what we are doing at this very moment to Bitworld! We are saying that according to the rules of the simulation, everything, everywhere has to march forward in lockstep. As much as we might like to see how it all comes out - whether that tear is going to break loose from Mercury's eye, for example - we may not. We can't throw more mana at it and fast-forward that one part of the simulation, because then it would be out of sync with all the other parts. It would break the world.
