Two new features are revealed by examining redshift from a position away from the centre of the universe. First, inter-galactic redshift is best recognised as a recession velocity. This was the way Hubble pictured the universe but it was later supplanted with expansion of space–time under the Big Bang Model. Unfortunately, expansion cannot explain the drift velocity because intergalactic redshifts do not reveal the change in redshift in the direction of the drift velocity. But, by using Hubble's understanding the redshift remains proportional to distance from whatever point you examine it, despite the absolute recession speed of the observer. However, using the recent CMBR surveys, we see a drift velocity that comes from our sun's movement relative to the static CMBR. Again, using Hubble redshift, this recession speed is invisible when looking at the redshift between galaxies.
All this demands a new model of the universe.
