The givens of Mass Vortex Theory are: a nebula (or part of a nebula), 10 big pockets of iron atoms (iron and other metal atoms), and a black hole. Atoms from the nebula pack in more densely around the pockets of metal atoms. We’ll call these dense regions protoplanets. When the black hole becomes present, it acts like a big sink-hole. The nebula starts to go down the drain which creates a kind of whirling vortex.
At some point, a protoplanet has too much mass and momentum to remain in the curved path of the Parent Vortex, and it moves radially out of the Vortex (as covered in a previous post). Like a baseball pitcher using his fingers to spin a baseball, the streaming gases of the Vortex act like fingers around the protoplanet to spin it as it exits the Parent Vortex. Thus, the protoplanet transitions into an orbit around the Vortex’s center-of-mass with spin.
The further away a planet is from the center singularity, the less curvature the Vortex has. With less curvature, the pinwheel arm of the Vortex has more time to drag the planet and create a faster spin. This effect is the reason that planets further away from the center of the Solar System spin more quickly.
