That's called the conservation of angular momentum.

This is because of a principle called conservation of angular momentum.
这是因为称为角动量守恒的原理。
Vox 观点
It seems to be able to right itself by flipping in the air without pushing off anything first, which would contradict the law of conservation of angular momentum.
它似乎能够通过在空中翻转而不首先推动任何东西来调整自己,这与角动量守恒定律相矛盾。

But the reason it’s moving away also explains why it will never leave us—a principle known as the conservation of angular momentum.
In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important quantity in physics because it is a conserved quantity – the angular momentum of a system remains constant unless acted on by an external torque.
