lbiar Posted June 1, 2010 Author Report Posted June 1, 2010 I have a hard time understanding you. Why do you say "the universe in the first 13.7 billion years don't like to exceed this speed". I have a feeling that you are mixing up two different kinds of velocity. Try reading, Cosmology Tutorial - Part 2 ~modest I'm according with you, but: Hubble's law relations distance-speed and also time (distance with time). So if the radiation of cosmic microwave background go before more quickly that c, later need to brake, if brake means: the the radiation of cosmic microwave background may to see at the average speed but for example if before the 1/2 time of the universe has slow the speed, the stars at 1/2 distance would see at 1/2 of distance but at real speed. (same if ti was at 1/4, 3/4, ...) - the light that we see of stars at 1/2 of distance is also at 1/2 of time. If this occurs the Hubble's law would be false, because the relation distance-speed don't concordate. So, to be according to Hubble's law (it's a law), the speed need to be constant, and how in a expansion threre is not real speed this is equivalent to a constant speed and by that the expansion is decreasing (a expansion to maintain a equivalent constant speed each unit of space need to expand decreasing). Thanks by your note. Please, say me errors of my note.
lbiar Posted June 2, 2010 Author Report Posted June 2, 2010 I would like to moderator that close this thread. I prefer to concentrate in only 1 post asking what I consider adequate. Also here I can't obtain a point in common with nothing. Thanks to all and sorry by the disturb.
