    Cosmic Plasma

    does just that , creates matter

    River . . . makes logical sense to me . . . . so, is your Cosmic Plasma basically a 'dark energy' matrix . . . or do you visualize it as like the Quark-Gluon Plasma (QGP) that has been hypothesized by others? Would not this Cosmic Plasma necessarily require that it be of an EXTREMELY HIGH energy density . . . . say, upwards of 10^+120 ergs/cc, or so"

    let me put it this way

    a galaxy doesn't spiral in towards its self , centripetal ( bb , big-bang theory )

    but spirals out ward , centrifugal ( cosmic plasma theory )

    What the cosmic plasma theory demonstrates is the energy output from spiral galaxies has an expansion effect. Do all the galaxies generate the energy that inflates the universal balloon relative to each of the galaxies?

    One possible source of energy for this galaxy connection is connected to the gravitational force. If we lower the potential in the EM, weak and strong nuclear forces energy is given off. If gravity is a force, what type of energy is released when gravitational potential decreases? If there is no energy given off, gravity cannot be a force like the others, since it departs from a common output schema used by the others forces of nature.

    I believe the lowering of gravitational potential does give off some type of output. If you look at the spiraling of a galaxy, this implies two things. First there is kinetic energy, which needs a source. The spiraling is also different that a radial collapse of the matter, in that galactic gravity will act much slower than radial. The energy output due to gravity potential lowering, causes motion and a resistance to gravity.

    Like the other forces, this energy output from gravity, should create a visual similar to gaining gravitational potential. We call it dark energy and dark matter since we can't acknowledge there is an energy output from the lowering of gravitational potential.

    The universe is great.

    . . . wrapped-up, perhaps, in dark energy?

    Necessity. Things are as they are because they could not exist in any other way.

    the Universe is infinite , because what makes it is Naturally infinite

    energy and matter and life as well

    The Universe is infinite. To be less than infinite still requires infinite nothing beyond it. The Universe is already zero, so infinite nothing isn't required. So the Universe is just infinite.

    nothing is non-extant

    it is indeed

    That implies that there were preexisting conditions; that something prevented reality from turning out in a fundamentally different way (or at least with a greater or smaller amount of energy). If there were indeed preexisting conditions then that implies that there was some sort of structure to reality before it began (in other words, that it existed before it began). If it didn't actually begin (is eternal in some sense), then talking about the necessity of how it turned out is nonsensical.

    Since all our measurement systems are relative to some frame of reference, I will take this one step further and say that in an infinite isotropic-looking universe measurement becomes meaningless.

    But isn't size subjective? So why cant the universe always be the same size and something else expands? We could be the size of a point to another being in another universe for all we know.
