Light is the only physical phenomenon of our experience that transits all three scales of the world we inhabit: infrafinite, finite, as well as transfinite. The concept of instanton accomodates the transition of thesescales in space and time. This fact indicates that the quantization might be in fact, the only true law of nature. In this respect the world we inhabit is unique: the Planck’s quantization procedure asks for a special fundamentalstructure of the universe as an optical medium, which must be a Maxwell fish-eye. In order to apply the Planck’s procedure of quantization to matter, one needs to extend the electromagnetic properties of the light fields to matterfields. At this juncture, the special relativity aroused a thesis which acts implicitly in all initiatives of theoretical physics: the length — which is a differentia of the concept of matter — is identical to the distance, which is aproperty of the vacuum concept, and can be revealed only by light. A proper usage of this thesis leads to the idea of Yang-Mills fields: the equivalents in matter of the electromagnetic fields from vacuum. The planetary atomicmodel, as the fundamental structure of the physical world is considered from this point of view. Consequences are suggested and/or described; some of them are pursued up to their conclusions, some remain at the level oflogical speculations.
