Kaluza-Klein theories show how you can get Electro-Magnetism from Einstein's General Relativity (gravity) if you assume an extra (5th) dimension which is a circle. A particle moving around this circle (i.e. with momentum in the 5th dimension) appears to a 4-dimensional observer (us) to have electric charge. It is quantized because the circle has a finite size. When you note that the (8) is a circle (O) we can move towards figuring things out. http://en.wikipedia.org/wiki/Kaluza-Klein_theory
This blog is to present a Sci-fi Aether concept of how ellipsoidal particles that make up a gaseous medium, can align themselves and form figure 8-shaped loopings or toruses; and thus becoming in essence elementary particles within the Aether.
Some of stuff on this blog is perhaps too far out, and completely wrong, but there are some more valid ideas to reflect upon. Anyway, I'm trying to get a good simulation going, so it all becomes more clear.
