It just tell us how rapidly it is expanding at different distance, but at the same time, NOW. So, there is no basis for the claim it was expanding very slowly in its very early history. AG Wrong conclusion! Since galaxies far away are receding the faster than those close to us, Hubble's law also says that those close to us are receding more slowly than those farther away. So, since in the very early universe the galaxies were closely separated, Hubble's law says they were receding from each other more slowly than today. AG That doesn't follow. That galaxies(near) are receding more slowly than distant galaxies(distant) now, does not imply they were receding more slowly in the past. *Yes, I think you nailed my error. Hubble's law just tells us the relative velocities of near and far galaxies, but doesn't imply the galaxies were receding from each other slowly in the very early universe. I'm still puzzled how I could get that implication. AG* In fact you can invert the argument: assuming they were all together in the past, those receding faster will now be further away. *What is "inverted" about the argument?
