An uncomfortable parallel can be drawn between the Big Bang story and the Christian myth of creation. At the root of the whole theory is faith, faith in things which cannot be seen or detected physically, such as an invisible form of matter and energy that is supposed to pervade the universe, or on a definite moment in time in which all matter as we know it came into being. The emphasis in theoretical physics and in mainstream cosmology is on pure thought and logic. Plasma cosmology on the other hand makes no assumption about the age of the universe; it places no limitations on the time available for large scale structures to form. The explanation for things that have occurred in the past lies in the processes that we see now, which in many cases we can explore in laboratory experiments. There is no effect without cause ‑ an infinite chain of cause and effect leads from now to the past.
