I remembered another question (a famous one) "why does the earth
rotate?". The common answer is because there is no agent to stop it. Can
we start with the idea that all heavenly objects were already rotating
when they started their lifes? Is it a good idea to accept the rotation
of the heavenly objects as an internal property of them - as we take the
concept of inertia as an internal property of mass?
