While I'm on a roll. As this medium decays into this universe, forgetting the mechanism for now, each matter particle and antimatter particle emerging from the infinity + infinity + infinity has brought its own piece of space with it. After their annihilation, the main residue is 2 bits of new space. Multiply this by almost infinity and you have a universe. This area of new matter is probably thousands of light years thick and always receding. The matter of the universe is attracted to this ever receding wall of new matter and is called Dark Energy or gravity.
This is what is fondly refered to as word salad. A word salad is made by adding some scientific terms from physics, math and cosomology. Then a dash of half understood scientific theory is added, then the whole thing is mixed together. The result is word salad which is what we have here.
It is great to be interested in science and physics. I recommend that you spend time in the science section of the forum and you will learn alot. The overwhelming majority of what can be learned in the fringe section amounts to the antithesis of science.
