The universe is not expanding in gravimotion's interpretation of Nature
The apparent expansion of the universe is physically based on red-shifts measures of light radiated by far away bodies of matter (discovered by Hubble).
Gravity, in gravimotion's interpretation of Nature, occurs as MOTIONS concurring toward the bodies of mass considered.
The quasars, galaxies and clouds of particles observed in our far surrounding horizon have gravities of their own, amounting to MOTIONS concurring toward them and as such straying in all directions away from us and creating the very red-shifts we are observing.
In gravimotion's interpretation of Nature, these far away receding gravitational MOTIONS, which are departing from us in all directions, take the place of science's expansion of the universe.
Nowadays science is no longer in favor of the interpretation in which far away galaxies are physically receeding from us; somehow the space in between the galaxies and us is instead expanding.
This latest explanation fits perfectly above gravimotion explanation, which involves the present mo(ve)ment (space-time) instead of a recession of the galaxies.
Gravimotion's explanation has the great advantage to avoid the fact that just in a few months an expansion of space would outrun light's own MOTION; the stars' light should by now be invisible at night; a disappearance that obviously did not occur.
In gravimotion's interpretation, the red-shifts are measuring the gravity surrounding these far away objects, eradicating altogether science's unrealistic expansion of space, yet (hopefully) concurring with science physical measurements.
