I used to think that one can measure the curvature of the our universe
in order to determine if it is finite or infinite in spatial extent.
But this is impossible. It could be spherically finite but so large
that it will be measured as flat with some very tiny error. But we can
never determine whether that tiny error is caused entirely by
measurement error, or partly by its slight curvature. That is, we can
never be sure that the error is due entirely to imperfect
measurements. Thus, we can never determine via measurement if the
universe is finite or infinite in spatial extent. AG
Science is never being able to say you're sure.
