You should read up on the significance of the aleph. The alephs are used to describe the cardinality of infinite sets. Think of it like this:
The real numbers lie on a line, with infinity possible divisions, which results in an infinite number of numbers in any subset of the line. The complex numbers, however, are an infinite set of ordered pairs, or instead of an infinite set lying on a line, it's a grid of infinite size extending in two dimensions.
Take some <i>n</i> from the real numbers, and some <i>m > n</i> also from the real numbers. You now have a set <i>{ n > x > m | n, m in R }</i>. For every x, there is an infinte number of correlating values in the complex numbers C, like its own real number line.
So in effect, assume the set of all real numbers has some size <i>p</i>; its cardinality is <i>p*1</i>. By corrollary, the complex numbers have cardinality <i>p<sup>2</sup></i>. Which set is bigger? Infinity 1 or infinity 2? Moreover, which set is bigger if you consider that both sets are infinite in size, but by definition the real numbers are a subset of the complex numbers?![]()
