Everything and Nothing

Can we put a limit on everything. I think we can. If we accept the notion that the universe is expanding then also I think it would be reasonable to assume that everything is also expanding. If everything is expanding then it must be expanding to fill a space that doesn't contain anything.

We can say this because anything would have to be a subset of everything. Therefor everything must be expanding inside of nothing. Therefor everything must be a subset of nothing.

If we were to go to any border or edge of everything and cross over we would find ourselves in nothing. This would seem to indicate that regardless of size, nothing will always be greater than everything. Everything exists inside of nothing.

Ultimately it may be impossible to say you are talking about everything unless you include nothing. You must believe in everything just as firmly as you believe in nothing. kj
