In Cosmology, it is the difference between "space is infinite" and "space goes on so far as light has had time to reach any of our instruments but not so far that the expansion of space will prevent light from ever reaching us" - Why complicate the theory because there are locations in space we can't see or change? In Relativity, it is the difference between "all points in time are equally real" and "only one point in time is real, (the present) but that present depends on where you are and how fast you are going and in what direction" - Why complicate the theory because there are points in time we can't see or change?
