First of all - please don't give me warnings if I write something that is not correct here. I'm just trying to understand the Big Bang theory, and I have some problems with it. OK, the red shift. What does it indicate? I don't believe it indicates velocity and distance, because there are numerous observations of quasars that seemingly have an arm connection to a galaxy, but where the galaxy and the quasar have very different red shifts. How can this be explained?
