Re 141: It might not fit in an YEC model, but the disparity certainly does raise questions of whether we understand all the factors affecting redshift. The object raises the possibility that we have significant "unknown unknowns" with regard to redshift.

This is quite cutesy of Danny. All the factors that relate to faith-belief and evolution-denying? Can Danny name two or three such factors?

significant "unknown unknowns" with regard to invisible gods, undiscoverable 'powers', faith-based rejection of pixies, 189 schisms in Christian theology.

Lyle is the same. He has a Theory of the Ark. He is probably a fraud, but maybe a true-believer. All of this can be explained by Pixie Theory. Teach the controversy. Follow the money.

Well obviously, by definition, I can't name "unknown unknowns". But I can name some known unknowns.

Known Unknowns

• The Dynamic Theory predicted significant differences in Redshift as measured on earth verses those measured by Hubble. Notice that in this 2001 paper from the University of Chicago that the theory was referred to as "New". Are you so all knowing that you can assure me that there aren't other unknown "new" theories that will impact our understanding of Redshift? Dynamic Theory
• The affect on light of travel through deep space. We assume there is little affect, but do we know?
• The effect of gravity wells. The blueshift on a proton entering a well is assumed to be offset by the redshift as it exits.
• Redshift due to Inflation vs redshift due to velocity. How much actual inflation there is/was affecting the light we are looking at. Is our model of inflation correct?
• Our location in the universe. Are we near the center or not?
• The composition of the universe.
• The affect of other dimensions and whether they exist.
• The initial conditions of the Universe.
