If the universe is a simulation, it would have to be on an analog computer which doesn&#x27;t have a clock speed as such.  Or a digital computer running sufficiently tiny time steps to be indistinguishable from an analog computer.  In either case I don&#x27;t think c is directly related to &quot;clock speed&quot;.  I&#x27;m not a good enough physicist to tell you what it does mean.  That&#x27;s my feeling anyway.
