First, we don't know that spacetime is quantized; that's a plausible speculation but we have no theory of quantum gravity.
Second, "quantized" is not the same as "discrete". A free particle in quantum theory is "quantized" but the spectrum of all of its observables is continuous.
- wnoise 5y agoIt's not even a plausible speculation; all of the best models we have, quantum mechanics, special relativity, quantum field theory, general relativity, and string theory have a fully continuous space-time. The one notable exception is loop quantum gravity.
