That's the key to people's mental block on this: Incredibly close to 1 is not the same thing as

*infinitely* close to 1. What do you think the mathematical definition of infinitely close to 1 is in calculus? Yeah. Get it yet?

It's like playing chess and arguing over how horses don't move like knights in real life.
