I dont know what mechanisms might be taking place at the molecular level but my assumption is that the workings of our universe and our reality is a carbon copy of the Cathode Ray Tube and how it works. Imagine ourselves inside the Television in a 3 dimensional world of pixels or atoms in our case. Each atom depending on its absorption of frequencies of light according to the strings length or code in string theory or its density and displaying the related color temperature. Plasma in the universe takes the place of the Cathode and provides the electrical charge. Now my assumption is that when Plasma comes in contact with a positive charge the EM field is produced perhaps to bind molecules together? But Im not sure how that would work either. Also a CRT has one vertical and one horizontal magnetic field that positions the pixel in space. Any ideas of a similiar function in atoms? If you look at how aCRT works at this link perhaps someone can shed some light so to speak on how it could work or couldnt?
