Earth's progression through the densities

[Spaced]

Since Ra is always using analogies to the motion of waves; vibration, distortion, etc., I always assumed they were using Density in the same way as you would if you were measuring density of light, like in foot candles, or density of sound-waves (which is equal to sound intensity divided by the speed of sound). If light/love is the building block of the Universe than would an increase in the density of light not also increase the amount of information carried by the light and offer new opportunities for experience? It makes sense to me also that these increases in density would have thresholds that separate it into different categories of density, since that is the way many natural systems seem to operate.

Then again, I'm just a 3D alien.
