The motion of gravitation existed before gravity could create mass. That motion is a wandering spin motion. The origin of that motion is the spin instigated by the photon of light; into the star smoke; dark pre-atomic dust, as the photon and the star smoke are ejected together; from the star or stars. Those pre-atomic dark matter, dust motes, are pushed out of the star by the photonic bow wave; and sucked out, in the vortex of the spinning photon particle. This occurs at almost the speed of light; but is immediately decreasing in speed as the particle or photon runs away from the dark pre-atomic motes; and the friction within the smoke slows the pre-atomic dust motes down from a centrifugal to a centripetal rate of spin; and the electro-static charge begins to slow the spin rate; and attraction can begin to assemble the dust motes into spherical assemblies of atoms. Those dusty spheres (i.d.p.’s) we call chondrules; or Earthy meteorites; are then formed.
There are those in science who claim that Dark energy is more mysterious and more important than dark matter. Let’s take a look at lightning in the clouds of our Earth’s atmosphere. Static charge is invisible, until it’s not. It needs moisture in order to travel; or a close proximity to another charged particle. Dark energy is no more mysterious than the electric charge due to friction here on Earth. The photons speeding thru the universe full of star smoke; create the dark energy in the whole of the universal fabric.
