Quanta, Georg Cantor, & Uncountable Infinite Series.

Arguably, the set of rational numbers is infinite but technically countable. However, there are an infinite number of irrational numbers in between each and every rational number, and these are uncountable. When Georg Cantor proved this by his diagonal method, he was paving the way for the uncountable infinite series of universes currently believed to exist both actually and potentially under quantum theory. The really difficult question for quantum theorists is whether merely thinking about measuring quanta has the same effect as actually attempting a measure.
