I'm probably getting the wrong end of the stick, but I'd think not based on conservation of angular momentum.

anonymous · Answer

yes rotation is possible in space for like infinite time, provided that , once that person should be rotated, he will keep rotating

anonymous · Answer

That assumes that an independent 'rotator' is present, and I assume that ganeshie was asking about an independent self-rotator.

anonymous · Answer

that could be possible , for being a self rotator a person need to move himself using is inertia , i think he can rotate, provided that there should be platform over which he can have force of friction or something lol

anonymous · Answer

By the conservation of angular momentum, he could only spin some of himself clockwise by spinning an equal part anticlockwise.
