Physical proof that infinity isn't real

Physicist frequently use infinity when talking about fields (ex. V = integral of E*dr from 0 to infinity) but if the fields were infinite, be they gravitational or electric, they would span the entire universe and all things effected by it would collapse into a single, crushing point. This has clearly not happened and is not happening. QED, infinity is not real.

This is more of a statement than a proof, but it's something:

But you should try to prove it for a few days if you have the time. It may be fun and rewarding if you have enough of start point on it to make some progress.
