The roots of astrophysical dogma are mired with vanity. I am pretty sure Eddington was one of those people who set us on a course of disillusionment with nature, Penzias caused much trouble too looking at the situation in hindsight. Here, read this and you'll see the assumptions fly, assumptions without evidence. Assumptions without thinking clearly.
