<i>&gt; Spinning motion is an illusion and doesn&#x27;t exist as a fundamental form of movement</i><p>If there is no objective space, then &quot;movement&quot; in general is not a fundamental concept; but you are assuming that at least some kinds of movement are fundamental (tarikjn points out something similar to this).<p><i>&gt; similar to how lack of gravity in orbit is an illusion, in that you are continuously falling downward but missing the earth.</i><p>Actually, you have this backwards; it&#x27;s the &quot;falling downward&quot; because of &quot;gravity&quot; that is the &quot;illusion&quot;, according to our best current theory, general relativity. In a free-fall orbit, you are moving in a straight line through spacetime; you can tell this by the fact that you are weightless.
