The big bang theory - Study guides, Class notes & Summaries

A few decades ago, there was great controversy among astronomers over the question of quasar distances, with some arguing that quasars are much nearer than application of Hubble's law would seem to imply. Why do nearly all astronomers now agree that quasars really are quite far away? - ️️We now have images and spectra that clearly show quasars to be embedded at the centers of distant galaxies and within distant galaxy clusters. A quasar's spectrum is hugely redshifted. What do most astron...
