６－２．Calculation of KH

        ACV＝Kｈ×（Haa＋Hba）　　Kh：constant of proportionality

               Hba＝KH×Hbb 　　

        ACV＝Kｈ×（Haa＋KH×Hbb）

              Haa＝Hbb＝Kc×IC 　  　Kc：constant of proportionality

      ACV＝Kｈ×（Kc×IC＋KH×Kc×IC）　

　　    ＝Kｈ×Kc×IC×（１＋KH）

　　   acv＝Kｈ×haa＝Kh×Kc×ic

        　    　Kh×Kc＝acv／ic

      ACV＝(acv／ic)×IC×（１＋KH）

   （１＋KH）＝ACV／（(acv／ic) ×IC）

          １＋KH＝（ACV／IC）×（ic／acv）

       KH＝（ACV／IC）×（ic／acv）－１

９．Ideas about space

９－１． The measuring method of the speed of the solar system through space

             

he frequency of the light from the star at space=f0

The speed of the solar system througu space=Vx

The revolution speed of the earth=v

The speed of light=c

The frequency of the light from the star at the earth=f+

      when the speed of the earth through space=Vx+v.

The frequency of the light from the star at the earth=f－

     when the speed of the earth through space=Vx-v.

 f+=f0×(1+(Vx+v)／c)×(1－(1－(Vx+v)^2／ｃ^2)^－0.5

 f－=f0×(1+(Vx－v)／c)×(1－(1－(Vx－v)^2／ｃ^2)^－0.5

　You can calculate f0 and Vx with these equations.

In addition, if f0s of other stars which are in the direction that the solar system moves are diffrent and Vxs are the same, I think that Vx is the speed of the solar system through space.

９－２． Vx and CBR anistropy

 If Vx were the speed of the solar system which move relative to CBR, space would have the black body radiation . And we can not find the difference between CBR and the black body radiation of space. 

９－３．Source of black body radiaion and the black body radiation of material on the earth

Source of black body radition has myriad of harmonic oscillator. But material on the earth does not have myriad of harmonic oscilltor. So, source of black body radition of the material on the earth may be the space in the material on the earth. So, black body radition of the material on the earth may have anisotropy which is the same of the anistropy of CBR.
