&gt; But even disregarding this, there seems to be a need to propagate something through space.<p>That&#x27;s the problem with QM.  So far as we can tell, <i>nothing</i> propagates through space.  Even if something <i>did</i> propagate through space, it does so faster than the speed of light.  And we know that information travelling faster than the speed of light is impossible.  Because if it was possible, we would have causality violations.<p>i.e. if faster than light travel was possible, the universe would necessarily look very different than it does.<p>So we have multiple experiments, all of which are true, and which <i>apparently</i> disagree with each other in certain esoteric ways.  Since the universe is consistent, we must conclude that the failure is in our understanding, not in the universe.
