Re: "In reality, physics is continuous."

That has yet to be established.

The universe could turn out to be finite and discrete - e.g. see my site:

It is confusion to argue from the continuity of the wave equation to the
continuity of the underlying physics - since there is no compelling reason to think that the wave equation is the final word on the issue - and discrete phenomena often look continuous if you observe them from a sufficiently great distance - e.g. see lattice gasses.

http://en.wikipedia.org/wiki/Loop_quantum_gravity is an example of a more modern discrete theory.
