The galaxies were very closely packed at that time, but their rate of separation, or shall we say expansion, cannot IMO be determined by the 1998 discovery. You prefer, and believe, the rate was very slow AT THAT TIME. But that's just your conjecture. I believe it was very rapid since the BB was likely a hugely violent event. But I can't prove that, and never claimed I could. AG * *> I never disputed that conclusion; only yours, that it implies that after the galaxies formed, the universe was expanding very slowly.* *Expanding "very slowly" compared with the expansion of the universe during inflation certainly. I will now make a statement that you dispute that I am nevertheless absolutely certain is true: * *Today galaxies are expanding faster than they were before galaxies started expanding faster. * *The reason I would be willing to bet my life on the above statement being true is because all tautologies are true.* *What tautology are you referring to? You really need to get your act together and cease with your foolish accusations. AG* *> Sure, after that the expansion slowed due to gravity, but the discovery of the accelerated expansion says NOTHING about the much earlier rate of expansion. AG * *Yet more evidence that you don't read what I write, not even the parts that I underline. * *More mind-reading by the a'hole-in-chief.

That's the issue, in case you can't remember. Sure, I read it, several times in fact, but I see no EVIDENCE for the conclusion you've fallen in love with; that in the very early universe, the rate of expansion was very low. Do you know the difference between FACT and CONJECTURE?
