When you throw a returning boomerang, it spins eccentrically.
It is saying the axis of rotation does no pass through the center
of masses. That spinning eccentricity along with its moment of
inertia, regarless the medium it can fly (air/vacuum), is the cause
of the boomerang's return, even in empty space (vacuum)!
Australian Aborigines knew that phenomenon since thousand
of years ago.
