For starters let me say that reading about and pondering cosmology is only a hobby, I have no formal education in this arena, although I am returning to school this spring to do just that. That being said, the following query may be foolish for some basic reasons I have missed, or not come upon yet, but I would be happy to know what they are. For the sake of this question let us say that the Milky Way Galaxy is at the center of a sphere, the sphere being our expanding universe. As we draw a radial line from the center of the sphere (A) out to its face our line passes through 5 other galaxies (B,C,D,E,F). Each of these galaxies are separated by each other by a decent amount of space, say 10 billion light years, and measures a red shift to its nearest galactic neighbors sufficient to put their speed of separation at 1/4 the speed of light. Galaxy A being the Milky Way, here are the 6 galaxies connected by a straight line each uniformly spaced. A----B----C----D----E----F My understanding is that since we on A measure a redshift of X to B and B measures a redshift of X to C we on A measure a redshift of 2x to C. Therefor we on A would measure a redshift of 5x to F, and since X=1/4 the speed of light galaxy F is "moving away" from A at a speed greater than the speed of light? If that is the case then even though F is "moving away" from A at greater than the speed of light it is still possible to travel from A to F while moving at only slightly more than 1/4 the speed of light?
