I think you question really is "why is Bodhiimportant in Buddhism". Bodhi is the word for enlightenment in Pali and Sanskrit. Bodhi is the goal of Buddhism.

I believe there is only one type of universe, a Quaternion four dimensional Universe. This Quaternion Universe has one real dimension and three vector dimensions. The universe has two "states", the Boundary state and the Internal state. The Boundary state is a minimum size, around r=150E24 meters. The Internal state is much larger than 150E24.

The steady state theory was disproved by observations in the sense that at larger distances, the Universe doesn't look the same as nearby. This means the Universe has changed over time, directly contradicting the main assumption of the steady state theory. - I am not sure to what extent quasars were involved, but quasars do tend to show up more frequently at greater distances, i.e., in the early Universe.
