Ladies and Gentlemen, The Openstax 2E Astronomy p.781 supernova outcomes has made me review this material again, to consider the Texas teachings again. I found it difficult first time through to listen to different opinions of Prof. Tegmark and also Prof. Koury on this Dark Matter topic, probably simply overwhelmed at many views. As a new person to hear many views on dark matter was overwhelming. Prof. Freese presents the dwarf galaxy models as being eaten by thr Milky Way, and this is good honesty to hear of this event. Prof. Schmidt in ANU presents the idea of a violent universe while tempering it by saying most quasars have ended. Dwarf galaxies may have been drawn to this galaxy when quasar activity still did not seem to allow for life to emerge.
