Without anything in the universe that could change over time and therefore indicate the passing of time that seems to be rather inconsequential to me at first glance, if it is even meaningful to talk about time in such a universe. I'd say I leave that to your choosing. Also have as many space dimensions as you like and whatnot, I don't want to be to picky. I just want to take away all the objects you could use to implement sets with and on top of which you could then continue to build more structures.
