- The discussion on L-S has apparently misled you. I believe that the
- space-time manifold is discrete, i. e. not continuous. There are many
- ways to discriminate between a continuous and discrete model and this
- has nothing to do with countability. Perhaps the most dramatic is that
- special relativity can only be approximately true. Einsten himself
- thought that it may not be possible to base physics on continuous structures
- and recognized that this meant all existing theories including his could
- only be approximations to a deeper underlying theory.
