To elaborate on this a little bit, you can think of the laws of physics as a differential equation, and the universe as a solution. You can imagine what would happen if the universe passed through a different state (just solve the differential equation again, with new initial conditions), or even different physics (solve the new differential equation), but how do you figure out what happens when calculus changes?
