>It's like how people don't realize that the sum of 1 and 1 is 0. Many smart people will disagree but it is nonetheless a fact.

No, it isn't a fact. This assertion is a common internet troll trick that relies on misusing the "product property of square roots" [i.e. sqrt(xy) = sqrt(x)sqrt(y)], with the "trick" being that the "product property" is only applicable for x,y >= 0 and x,y ∈ ℝ, and therefore cannot be used to "prove" 1+1=0.

Why purposely mislead people who may take you at your word?

Oh, I'm working in Z_2 with addition defined naturally.

Sort of just a joke, eh? Your definitions can place you in a different place for a different answer. And everyone really does know that. Time-averaged Euclidean vs. Euclidean closest approach vs. rank on the total order definable by orbits' parameters vs. energy needed to reach. So it's a bit pointless to go on about how "the universe doesn't need to make sense" like GGP and be dramatic about it.
