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.

>>120
0.999...<1

simple proof why 0.999... is not equal to 1
0.9 !=1
0.99 !=1
0.999!=1
any number of nines you take :still not equal
