Not necessarily, there may be something underneath space-time. That is,
something that provides the building blocks for space-time.
Just like nature provides ways to enhance the building blocks of today's
computer (and thus allows to increase the speed of the masterclock, nature
may also provide ways to enhance the velocity of information transfer.
