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 dimension of ours (that obviously u don't belong in) is linked with time, time defines every thing, you know the number     10 exponent 100 after the maximum possibility of finding a exact copy of a body becomes possible and maximum, then why can't there be an infinity, that would not make scenes  that reputation could be finite
