A star spits out photons of light; and pre-atomic dark matter dust or star smoke. The photon particle of matter has two motions; a forward motion thru the void of the universe; and a spin motion of variable rates of revolution as determined by the photons mass. The mass and diameter of axial spin of the photon is an expression of color and the exact angle of refraction that is possible by that particular photon; when it impacts to a curved surface; such as a convergent lens; ie; a drop of water; or blood.

The spin or gravitational motion is in part transmitted to the lens; as the spinning photons refract to a focal point. After the focal point of the convergence; a motion of divergence forms a secondary cone of light; from which a reactive motion emerges.
It would appear that nothing is lost in the process; because every-action having an opposite yet equal reaction; the double helix of creation is the result; as gravitation going into the focus is rewarded by the outreach of the force of gravity.

It’s worth considering that when the photons and their bow waves are created coming out of the stars; the exhaust vortex of the photon particles also sucks out the pre-atomic star dust or smoke; as a trail or swirl; like that trail which is seen behind a 50 caliber bullet when it’s fired from a sniper’s rifle. The bow wave in front of the photon particle of light pushes the particles or pre-particles out of the path of impact of the particle; and the spin of the particle gives stability and distance of travel to the photon particles; and just like in the double slit experiment the bow waves motion is out front of the particle; the particle creates the wave.
It is a foolish notion to ignore the fact, that the wave can’t exist without there being a particle to create it. The photon particle is matter; photonic spin is the instigator of the creation and assembly of mass; and mass is the evidence that time has passed.
