Hmmm I did not realize conservation of momentum was absolute hogwash. News to me.

in space? in a vacuum? being affected by literally 0.0001% of all mass of the rotating body?

Short video lesson for you:

that's not a sphere, those hammers are changing distance to his core by more than 50% of the total distance, ice caps on earth do not reach the same % difference in height

completely irrelevant video

You really need to go back to school.

It’s good to learn.

No, no, no. This is conservation of angular momentum. Completely different.
