The Universe - some information to help you live in it. Bigger than the biggest thing ever and then some.
Infinity is just so big that by comparison, bigness itself looks really titchy.
Gigantic multiplied by colossal multiplied by staggeringly huge is the sort of concept we're trying to get across here. It is impossible to import things into an infinite area, there being no outside to import things in from. It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds.
