(1)    The evolution of galaxies is essentially the reversible process of the mass polymerization and the mass dissociation.( the mass fusion and the mass diffusion ), and the universal law of the star evolution is the co-evolution law of the solar star and the planets.

(2)    the definition of the co-evolution law of the solar star and the planets:

(a)    the solar star and the planets can only evolve in the co-evolution system with the interactive mass-energy transform and the mass-energy exchanging through the unified double hole mechanism

(b)    in the co-evolution system the general evolution trend of the solar star is increasing it’s mass density through the mass fusion and the mass polymerization process to produce the multi-magnet iron balls in the core area of the solar star while the general evolution trend of the planets is decreasing it’s mass density through the mass diffusion and the mass dissociation process to have the high density of iron like material diffused to the low density level of composed with main hydrogen and the helium material.

(c)    In a solar star system all the planets are releasing the neutronised particle streams from all directions into the core area of the solar star to help the magnetic iron ball formed and to promote the grow up process of the iron ball in the center of the solar star, while the solar star in return to release the protonised particle streams to all revolving planets to promote mass dissociation process of the planets and to have their high density metal material to be diffused into the low density level of the gas of hydrogen and helium.

(d)    When the co-evolution process evolve to the binary period, the solar star will evolve to be the “female binary star” with the multi-iron balls pregnanted in the core area of “ the female binary star” and while one of the quality matched planets in the solar star system will evolve to be “ the male binary star”. When the male-female binary stars ready to produce the new born planets they began to rotate in the intertwine style.

(e)    When “the male-female binary stars “ rotate around each other with their intertwine rotate and this special binary star rotate will produce the powerful centrifugal force to project the mature magnet-iron ball into the space, when the female binary star project ing the new born magnet-iron ball into the space it also accompanied by the huge energy releasing that will leads to the sharp increasing of the brighteness of the binary star before they totally merged. And the merged binary star will become the young solar star with the bigger quality, and the young solar star will automatically establish the new solar star system with the quality matched planets to star up the next generation of the co-evolution system.

(f)     the projected iron ball from the female binary star is the primitive planets with the powerful magnetic force that will attract some smaller new born planets as it’s satellite and all the primitive planets and it’s satellite have the same style of “the body contact “relationship because they both have the very strong magnetic force to attract each other. And all the primitive planets and the primitive satellite will have it’s rotational axis  intersected with the crossing angle of 90 degree.

90 degrees of spin axis intersection principle

(g)    The principle of the 90 degree intersection:

 the postpartum binary star merge and the primitive planets and it’s satellite are all follow the 90 degree intersection principle which means the axis of merging binary star have their axis intersected with the 90 degree angle.and the primitive planets also have their axis intersected with the 90 degree intersection angle.

(h)   Mass diffusion principle of all elements on earth

All of the elements on earth are come from the mass diffusion ( mass dissociation ) process through the double hole mechanism of the reversible mass-energy transformation follow by the co-evolution law of the solar star and the planets.

(i)     the balancing principle of the repulsive force and the gravity force in the solar star system

the traditional theory to explain the principle of all planets that revolve around the sun is because of the big quality of the sun which produce the super powerful gravity force to attract all planets revolve around the sun, such a saying is totally wrong ! in our solar system the 90% of the gravity force is not come from the sun, instead , the most of the gravity force just come from all planets themselves because of their high density mass structure And all planets produce the 90% of the gravity force to attract each other, and the sun in the center just only produce the repulsive force instead of the gravity force and the sun actually play an important role to use it’s repulsive force to isolate all the planets to their safety orbit to avoid the all the planets colliding each other due to their strong gravity force because of their high density.
