@Caleb,
You see a chair, and you say "the chair is there". You turn around, and now, "the chair is no longer there."
If you apply this reasoning to the universe, then the concept of absolute nothing is exactly the same as with the chair. Only applied to the universe.
The funny thing, however, is that this resoning is false. The boundaries you associate with "chair" are completely subjective. Another person might have two words that describe the bottom and top of a chair, respectively. To that person, there is two objects. This works for just about anything. What's more, the chair never is "not there". Everything that is; is. It doesn't fade from existence. it just changes constantly. Things that don't exist doesn't refer to some nether-reality holding a bunch of things that are not in reality. It refers to things that we don't percieve.
Even then, that's based on faulty reasoning. The statement assumes that there is a
thing that we don't percieve. Truth is, there is just perception, and there is the wanting of a perception. But nothing, really, by virtue of it's definition, really doesn't exist.
