I think it has to do with the concept of computable vs non computable functions.  One stand is that if the Universe is a simulation then by definition it is computable but we can clearly define and reason about non computable things (which suggests that it is not in fact just a Turing machine and may in fact the hyper computer running the simulator.  But you can&#x27;t really get above that.  So the speed of light is just a defined constant which no meaning and we can&#x27;t pierce the through hypervisor.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Simulated_reality#Computationalism" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Simulated_reality#Computationa...</a>
