Infinity is 100^100^100^100^100 divided by zero.
“Hey Siri, what’s zero divided by zero?”
“Imagine you have zero cookies, and you split them evenly among zero friends. How many cookies does each person get? See, it doesn’t make sense. And Cookie Monster is sad that there are no cookies. And your friends are sad because they don’t exist. Oh wow. This escalated quickly.”
Which infinity are you talking about? Georg Cantor showed that in the transfinite realm there are infinite sizes of infinite sets, the smallest infinity being the infinite set of counting numbers (which also includes the listable set of rational numbers).
