Of course it shifts all wavelengths by the same factor. So the spectrum of atoms are shifted accordingly. With v = Hd the red shift factor is z = v/c = H(d/c). for H = 70km/s/Mpc for v = c we then have that d = c/H = 3x10^{5}km/s/(70Mpc/km/s) = 4.3x10^3Mpc = 1.4x10^{10}ly. So at z = 1 there lies the cosmological horizon. We now observe galaxies with z = 8 and the CMB has z = 1100. One can however thing of these photons as emitted prior to these systems crossing the horizon. LC -- You received this message because you are subscribed to the Google Groups "Everything List" group.
