force at a distance

基本解释

A proton contains three charged quarks bound by the strong force and its radius is defined as the distance at which the charge density drops below a certain value.
一个质子由三个带电的夸克通过强相互作用力结合而形成，它的半径是由电荷密度降到某一确定值的距离来确定的。
Venus and the Dark Twin are caught in the cup too, and the Repulsion Force is forcing a distance between them and the Earth, thus pushing the Earth toward Planet X at times.
金星和“黑暗孪星”也被困在这个“杯子”里，而排斥力在它们与地球之间造成了一段距离，所以不时地会推动地球朝行星X靠近。
