What method is being used to discover whether we live in an unbounded universe,in which expansion will continue forever,or a bounded universe,in which expansion will eventually turn into contraction and lead us to re-collapse?
A) careful monitoring of the Moon-Earth distance to detect the slowdown of the expansion of the universe
B) measurement of the deviation from uniformity of the cosmic background radiation
C) measurement of the curvature of the Hubble relationship, v = H₀ d, at large distances
D) measurement of the bending of light by distant galaxies as it follows the curvature of space
