Say you have an observer that is not on planet Earth. He then tries to measure the momentum of an object traveling on the Earth itself. He notices that when the object travels in one direction it has an added velocity of the Earths rotation, then in the other direction the object loses velocity due to the Earths rotation. On Earth an observer, Newton for instance, measures that the inertia of an object is the same when the object is pushed in either direction. So then how could an observer not on the Earth show that the relativistic two-way momentum is the same? Assuming they both measure about the same relativistic mass, the two observers would measure two different velocities, but that does not give the same answer for their momentum...(adsbygoogle = window.adsbygoogle || []).push({});
