  The incorporation of an adequate discrete expansion to the formalism of the
special relativity that does not allow gravitational acceleration unravels
unexplored phenomena. This extension takes into account consequences of a small
variation of the limiting velocity for a large scale of time together with the
space-time expansion. It determines a natural boundary between physical systems
with high and low kinetic energy, provides a new insight for Earth revolution
since its formation, indicates a new factor that maintains the earlier remnant
heat inside Earth, indicates that the self-sustaining nuclear fission chain
reaction that generates Earth major heat is increasing together with the
space-time expansion, provides a new lead for the problem of galaxies missing
mass, shows how time is entangled with space and expansion and leads to a new
interpretation of its characteristics.
