&gt;<i>doesn&#x27;t quantum mechanics mean everything has a lowest resolution of discrete steps, ie. Plank-time and Plank-length. In that sense, calculus over finite terms is enough.</i><p>That&#x27;s one solution yes, but whether the universe is continuous or discreet is not a &quot;solved&quot; problem in physics in general. The lowest resolution could just be a &quot;sampling restriction&quot; (or quantum laws etc) and not the actual reality. There have been some experiments to discern between the two cases, but nothing conclusive IIRC.<p>&gt;<i>The paradox is illogical anyhow, it fails to equate simple v</i>t=s.*<p>That&#x27;s not being illogical. v<i>t=s is not logic, is just a formula that we deduced and which matches what we see in everyday life (and in fact it&#x27;s not absolute, e.g. when it comes close to the speed of light etc).<p>The paradox just checks whether v</i>t=s is compatible with certain descriptions of the chain of events that look intuitive at first.
