A flat universe with dimension is a contradiction in terms.
True flatness is an impossibility.
There is either nothing or something.
And closed and saddle are suggestive of external influence or pressure or even boundary.

They have to do with the topology of the universe and the topology has something to do with the shape.

It could also be finite now but expand infinitely.
Only meaningless looping of words hoping they will actually mean something to others.
The facts and truth tell another story.Perhaps we share the same aspirations.
And relevant facts and truth are currently unattainable.
