Scientists say the the acceleration of the universe is increasing.The further away an object is, the faster it is moving away from us.Ok, Ill buy that,but the further away, the farther back in time that object is, which to me says the the universe was expanding faster when it was younger.How do they resolve this fact to arrive at their conclusion of a presently accelerating universe?We have no idea exactly where the galaxies that we see are right now,only where they were billions of years ago.
Curious.
