Physics - An Unjustified Assumption?
When you describe a system using differential equations (or partial differential equations) with respect to space and time you're making the assumption that space-time is continuous (i.e. infinitely divisible). That's a massive assumption, and if it's wrong you could be missing a lot of physics.
Many theories make this assumption, for example Einstein's General Relativity.
