center of mass too, for calculation purposes. It seems to me
gravimagnetics or some other invention is essential to restore
conservation of angular momentum, at least on an instantaneous basis.
Another related factor which might enter into consideration here is that
instead of angular momentum being conserved separately from linear
momentum, it could be instead (as an alternative hypothesis) that only
the cross-product of the two is conserved.
Newton and the mainstream assume that linear and angular momentum are
individually conserved. Or, in other words, that linear momentum cannot
be converted into net angular momentum, and vice-versa.
That is the accepted POV according to mainstream physics, but not
according to several other (fringe) observers like:

Take it for what its worth - it's not exactly a new wrinkle, and the
effect is tiny - and many well-armed experts will scoff at the
suggestion, but nevertheless the wrinkle of two interacting kinds of
momentum has not been ironed-out to everyone's satisfaction yet.
