- gpderetta 9y agoIANAP but as far as I understand, neither time nor space are believed to be discrete in the mainstream physics model.

- jessriedel 9y agoThe Planck length describes the scale at which current known physical theories breakdown, not become discrete. Although some hypothesized extensions involve discretized time and space, there is no concrete evidence for this hypothesis.
- Simon_says 9y agoDiscrete space or time would cause some problems for the equivalence principle - that the laws of physics should look the same to all observers, irrespective of their relative velocities. It's hard to imagine how physics could look the same to all observers if spacetime is a discrete entity that can be contracted by different factors along different axes for different observers.
