Forgive me for posting in a thread that hasn't been active for more than 60 days (I saw the warning) But this conversation interests me. =p
The universe is made up of space, because without space you can't really have the stuff that the space occupies. I think it's that simple. It's like, do you spend time in a small closet full of a lot of junk, with no room to breathe? Of course not, nobody would do that- or you would die. Space lets *everything* be.... the reason Buddhists and certain religionists (as well as philosophers) emphasis emptiness, and 'Nothingness' and 'space' is because that's the very essence force that allows All to exist.
Now can space itself be considered a 'something?' I think that answer is more of a 'yes' and 'no' thing. If it was a 'something' like the corporeal matter was, it would just cause more clutter. But if it was a true negative, it would be a black hole that innately and purely got rid of the 'something.'
I think this also explains why the universe adores ambiguity and ambivalence-y and doesn't like neat, pat answers. It thrives on complication and 'Yes and no' answers and 'It depends' and Yes' if x meets y to the z axis but only if D isn't in the mood of scorpio under the water blue fall of the great mood provided that- then back to the original score of Plato - blah blah blah.
There's a larger picture here. The universe as a whole is mainly concerned with balance. The reason rpg games are so popular- it goes back down to the basics. A fire-type creature is strong against fire, maybe lightning too- but weak against water/ice. That's a very simplistic version of how the universe operates. Everything that exists has things that its both strong and weak too- and you can narcissitically improve yourself (be a 'boss') to be very strong, but if you do THAT then you will be vulnerable to liberalism and faggy working-together-ness. You can try to have no weaknesses, but upon doing so you will just be weak against teamwork. Of course the contrary is true, if you act too goody goody and 'hippie-like' then you will just become easy to prey to bullies and thugs. When you try to get really good at one skill, you are avoiding getting good at another skill...the balance is balanced around the balance. But it has to be this way: Because everything is at stake. Or you couldn't ever get what you wanted.
