Origin Of Galactic,Stellar, Planetary and Satellite Rotation/Formation As Tangential Accretion Of Decaying Relevant Orbital Material Sections Transfering Orbital Angular Momentum To Accreted Body Thereby Increasing Its Rotation Angular Motion: A Natural Law

Stars, planets and satellites began as cores orbited by sections of relevant material. Due to gravitational attraction the orbits of these sections decayed and then  tangentiaklly is the Iaccreted to the more slowly rotating cores to rotate faster due to addtion of the sections' angular momentum: If Iω (core)  is the rotational angular momemtum of a pre stellar, planet satellite core,  and Iω (orbiting section) is  the  angular momentum of the orbiting section, the equation for the origin of stellar, planetary and satellite present rotation is:

Iω (core) + Iω (section 1)+ ...+ Iω (section n) = Iω ( newly formed star, planet, satellite). Two armed spiral galaxies began as pairs of pre formed galactic arms in linear motion . Due to gravitational pre formed arm attraction the orbits of each arm began to decay and tangentiallty accreted in their fore sections forming two armed spiral galaxies which began to rotate.Origin of two armed spiralgalaxy rotation is the transformation of  orbital angular momentum of each pre formed galactic arm adding together when attached into the final rotatioal angular momentum of the newly formed two armed spiral galaxy The equation for the origin of two armed spiral galaxy rotation is :

Iω (new 2 armed spiral galaxy) = Iω (arm 1) + Iω (arm 2) .The basis of this abstract is the formation of  a two armed spiral  and a two arme barred spiral galaxy appearing in a coffee cup on the sufrface of the coffee after adding some powdered coffee creamer to the coffee in the cup.Two armed spiral and barred spiral  galaxy forms may be universal patterns in nature appearing in a coffee cup on a smal scale and in outer space on a  grand scale.
