Good to see people with a level head.

So! tell me more.
What do you think of Plasma?

The mass-energy density of the universe is obviously unknown. What can be measured to some extent is that figure with regards to the visible universe. Beyond that, one has to know the history of the universe (which depends on the model). Certainly according to the mainstream, that figure is very low (with or without 'dark' stuff) because the universe is not much larger than what is observed at the present time.
Interestingly Quasi-steady state cosmology QSSC has an infinite universe with galaxies streching as far as one can ponder, then some. There was no first galaxy from what I understand.
Plasma is cool. But I would image that gravity is the long-range force that determines how the universe evolves on the large-scale. That is not the case in plasma cosmology. Locally, within our Local Group, it certainly is gravity that controls structures like the galaxy cluster, galaxies, planetary systems, so why not the rest of the universe. If I recall, electromagnetism is the main factor in plasma theory.
I do believe the universe is infinite in spatiotemporal extent.
