I have never understood how, when only one face of the moon is ever visible and that face is gravitationally tide-locked - As if on a chain with the Earth's axis, it is rational for science to teach that 'due to its rotation being in sync with its earth's orbit (27.3 days), it is impossible to observe the moon's rotation.
From earth, it's impossible to see most of the far side of the moon.
If you tie a string to a ball and swing it around your head.......Does the ball rotate - in and of itself?
No, it does not.
The ball is rotating, and its axis of rotation is where your fingers are grasping the string.
