Constant speed of light and quantisation of matter in the stable and semi-stable state
IF 'c' is a constant AND there is a finite speed range for matter [0,c)
THEN there exists a supreme(upper limit) of the number of communications (relative speed assertion between two frames) at an given time t>0 for an individual particle.
This then suggests a possible origin of the discretization/quantization of matter in the stable state even the life-time of those in a semi-stable state. Having been formed in the core of a sun in a series of interactions which involve high energy <=> highly relativistic physics, A restriction on the number of interactions which can be simultaneously undertaken by a given reference body would lead to a discrete number of formation interaction configurations, in turn thus resulting in a discrete sequence of values which are possible for any given particle's rest mass upon completion of it's formation interaction. Not only would that discrete sequence of rest mass mean the quantisation of matter in the stable state but also in it's interaction with electromagnetic fields there after. Which we do.
