>>I'm still not understanding the paper. I know that many assumed that the Doppler effect is the cause of the redshift relationship between our galaxy and others (well except for those that believe in gravitational time dilation). Is the paper saying that redshift does not occur or that light shifted towards red does not mean an object is moving away from you?

My physics professor Dr. Paxon, told us, “The most famous thing about me is that I married the niece of Max Planck”! :)
