When we use GR to calculate the properties of space-time when we are looking at a smooth distribution of matter which is both isotropic and homogeneous, we find there are essentially two answers: space-time is infinite, and is either expanding or contracting; or space-time is finite and wrapped into a (hyper)sphere, and is either expanding or contracting. In all these cases, the matter is not moving, but the space istelf is expanding (or contracting).
So let's refresh your TWO possible answers:
-Space-time is infinite and expanding.
or
-Space-time is infinite and contracting
or
-Space-time is finite and expanding.
or
-Space-time is finite and contracting.
or
-It is none of the above.
Oh, and its false on some scales...
Well, there you go.
Now I see why you feel you are ready to move on to economic theory!
