In a plasma cosmogony hypothesis, the stars are formed when cosmic Birkeland currents twist around one another, creating z-pinch regions that compress the plasma into a solid. Laboratory experiments have shown that such compression zones are the most likely candidates for star formation and not collapsing nebulae. When stars are born, they are probably under extreme electrical stress. In that case, they will split into two or more daughter stars, thereby equalizing their electrical potential.
The sky looks to random for a pure z-pinch ignition. If all stars have been compressed by z-pinch the sky would look like an atomic model of NaCl or a perl necklace.
Gravitiy is not the force of colapsing nebulae. But probably electro static clumping. Only such a clump can be ignited by a current. Once ignited to a sun the above said is true for the sun and the remaining gas and dust within n AU. Its a "coincidence" that a z-pinch hits a clump. Hence the random sky.
Once gas and dust have been compressed all their tiny angular momentums, a heritage of the galaxy, unite to a gravitational force worth to mention.
