I was wondering how spacetime could be relative and quantized. It doesn't make sense to me. I am especially interested in how this works in causal dynamical triangulation. I think it is a very interesting theory, and it sometimes doesn't get enough credit. But, I can't understand how at a tiny level, all spacetime is quantized, where at a macroscopic level, spacetime is continuous and relative. If anyone could help explain what I'm missing here, that'd be great!
