I'm definitely not an expert, but I was under the impression that both space and time are already thought to be discrete and have minimum quanta, Planck length (10^-36 m) and Planck time (10^-44 s). I guess this new theorem suggests that not only do they have minimum values, they don't exist between these points. Sort of like how pixels aren't really sized objects, but they sort of fill the space between them -- this might be a terrible analogy.
