Does God exist: A hopefully civil and fruitful debate

You definitely can use infinity in math. I do it nearly every day in my nuclear power classes. An open is defined as infinity ohms of resistance and a short causes infinite current. Of course, that's only the math of it, in reality you aren't going to get infinite current or you would have endless energy. We also use imaginary numbers which are the negative square roots of a number.

I should have made myself clearer: You cannot do arithmetic with infinity, it is a concept, not a number, not a thing that arithmetic applies to.

Reminder: I find it hard not to sound annoyed, but please refrain from claims without justifications. Even if you have to back up those claims with "because I ate sunny-sideups for breakfast today", please do so.
