Galaxies appear redshifted. The farther away they are, the more redshifted they are. The accepted explanation for this is that these galaxies are moving away from us, probably because of some expansion of the universe. The farther away they are, they faster they move away. Is this basically correct? Can anyone point me in the direction of evidence that the apparent size of distant galaxies appears to shrink, and that the farther out they are, the faster they appear to be shrinking?
