We can think of photons as projectiles; and every star is a source
of photons and pre-atomic dust; both photon particles and preatomic dust are being ejected from each and every star; blasting outwards in every direction. Every photon projectile is pushing forward with a bow wave of compression pushing outwards and moving the fabric of the dark matter dust that’s in its path. The so-called universal expansion is the collective force of all of those photons; pushing the star smoke or pre-atomic dark matter dust ahead of the photon particles.

There is a simple device called a radiometer which looks like a
light bulb; but it has inside its vacuum sealed globe; four vanes
which are black on one side and which are set into a spinning
motion when struck by Sun light. The instrument demonstrates
that light particles carry a pushing force; so when the radiometer
is sat in the Sun light; the vanes are caused to move in a spin
motion. That same particle push is moving the pre-atomic dark
matter dust into an expansion of our universe; which is also a
near vacuum; and is the home to countless stars.

The double slit experiment proves that light is a particle; and that
particle has a bow wave out in front of that moving particle.
Common sense and Occam’s razor say that in order for mass to
exist it had to have a source from which it came. Turn off all light
in the universe, and there would be no-thing. Light, photons and
dark matter pre-atomic dust are created in the stars. Light moves
in two ways; it goes forward and it has spin. When that photon
exits from a star; it has a bow wave of pressure; and a vortex of
an exhaust like spin. Both motions combine in pushing and
pulling pre-atomic dark matter dust or star smoke dust into the
emptiness of space. That pre-atomic dark matter dust thru the
spin induced friction gradually attracts via electro-static charge
and the spin motion of gravitation; into atoms which contain
gravity; in mass. (The motion of gravitation is spin.)
Time being created; as change is created in mass; by the photon
and its motions. There is no space time; there is only matter time;
as change is notable in matter.
