Bob Loves to Rotate

Bob can rotate.
He feels so happy when he spins and turns all the time.
It's his favorite thing to do, spinning all day long!

But wait, in that universe, there is no day or light!
It's always dark. However, Bob doesn't mind because he can rotate.
He has rotated so many times that he has become an expert at it, and he's really good!

Do you think he can stop rotating?
Do you think he can spin faster?
Do you think he can move to another place?
Do you think he notices that the sky is black without any light?
