Finite yet unbounded space?

Finite yet unbounded space?
Hey guys, do you think the theory that say "universe is finite yet unbounded" is a rational and plausible explanation? IMO the "finite but unbounded" universe is still a limited and finite universe. I think, universe is neither finite nor infinite because finite and infinite imply size, and size is a property of matter and space is nothing. We also can't say space "exist" because space isn't an object because it is nothing. So I will say space is eternal which mean have no beginning and end.
Any thoughts?

My thought is can you please translate that into correct English, (with no nonsequiturs)? Spacetime is not "nothing", as Krauss pointed out. Insufferable knowitall.

Finite and unbounded means that the geometry of space is closed. The twodimensional analogue is the surface of a sphere. That surface has no edges. In this kind of space, if you travel in a straight line you will eventually return to where you started. Skepticism is not a position; it is an approach to claims. Science is not a subject, but a method.

I mean, space is neither finite nor infinite because both of these terms can only be applied for objects, because only object (something that have shape and location) have size. What do you mean by "spacetime isn't nothing"?

Pay no attention to the troll behind the curtain, spouting ittelevant hypotheticals. Spacetime is not an "object". Think dimension(s). Insufferable knowitall.

In my opinion, universe or space don't have any size, geometry, topology, dimension, etc. and universe is not finite or infinite because, space is not an object. Isaac Newton pretty much thought this too until he conceived and preformed this experiment: Spacetime is a physical thing.

See also: Frame dragging.
Give me your argument in the form of a published paper, and then we can start to talk.
