hello there, I am totally into all astrophysics. so I want to know, how fast is the known universe at the most outer edge moving? or in other words, how fast is the most outer edge expanding away from earth. - and whats the rate of acceleration? I mean even if, as I understand it, the space between galaxies is increasing, there should be a know parameter to this effect by now. is there? I wonder why no one is ever mentioning the speed. again lets say the relative to earth (or milkyway) speed. or .. the rate of expansion - generated space over time. courious what comes now..
