８８ Gravity of Dark Matter【Exploring the universe】Dialogue with the Universe
・Gravity of Substance is represented by F＝G・ｍa・ｍb／square of L.
（G：gravitational constant、ｍa・ｍb：mass、L：distance）
・Dark matter, despite about５ times presence of Substance, is distributed spherically around the galaxy.
・From the above, assuming Gravity of Dark Matter to be represented by
Fd＝Gd・ｍa・ｍb／n-th power of L,
n is estimated that less than 1.
（Gｄ：gravitational constant of Dark Matter）
