I&#x27;ll take a stab, but I&#x27;m basically a layperson as well, so take this with a grain of salt.<p>Causality would be tough to apply I think because of the quantum nature of the interaction. The object initiating the motion is quantum as well, so it&#x27;s tough to say precisely when it should interact. So it&#x27;s not as if the object is &quot;anticipating&quot; the interaction, it&#x27;s that the quantum field already is interacting before our classical intuition of a non-quantum particle would say it is.<p>At least, I think :)
