- drdeca 6y agoQM doesn’t assume space is discrete. It does deal with a number of discrete quantities though. Are you sure that’s where the conflict is? I think people have done QM with a given curved spacetime, just, where the spacetime manifold isn’t decided based on the distribution of matter and whatnot? Like, I think that’s where the ideas of Hawking radiation come from?
- mhh__ 6y agoQuantum mechanics is not inherently discrete. We don't know whether the planck length is fundamental or not, but current models are in terms of continuous spatial and rotational degrees of freedom (in general). The eigenvalues often are quantized, however.
