Gravitation Chain

Most of Planets'(or Stars') Motions are Not Classical "Kepler" Motions

Some abnormal phenomena about gravitation appear just as a result of "Sibling" gravitations from other planets, not the "Parent" gravitations from the central star.

萬有引力理論是否僅存在於太陽系。

星系外圍恆星為甚麼離得越遠，反而速度越快呢？

（可以用磁鐵的有效範圍來類比）

那麼你對這些邊緣恆星運動速度沒有明顯變慢的解釋是什麼呢？

在恆星被捕獲之前，該恆星就已經有了一個初速度。在離中心比較遠的地方就會受較小的引力，但為甚麼沒有所謂甩飛結果呢？因為週長已經足夠大，此時父引力已不起主要作用，兄引力開始起主導作用。如潮汐作用一樣。

在外側行星和內側行星都在以同方向圍繞中心運動時，內側行星對於外側行星的引力整體上來看是助力而不是阻力。

This statement refers to the hierarchical structure of feudalism, a social and economic system that was prevalent in medieval Europe. In this system, a lord is a person who grants land or other resources to a vassal, who in turn owes loyalty and service to the lord. The vassal may also have vassals of his own, but these individuals are not considered to be the direct responsibility of the lord at the top of the hierarchy. Therefore, if someone is the vassal of a vassal, they are not considered to be under the direct authority of the lord at the top of the hierarchy.
