Along the same lines as the OP, I've wondered if some sources object to the application of proper time to a photon because of these definitions: a photon follows a light like path, proper time is the time of an inertial clock along the path of an object, "In relativity, proper time is the...

Isaac, you said: "...just confirming my knowlage that quantum gravity has a fundamental unit of space,while GR requires infinitesimal units of space..." yes, they do. But not likely for the reason you may think. The 'discreteness' and 'continuous' are fundamentally different input...

Isaac..." another set of laws is needed"...?... great question...again! maybe...seems it is an open question. Rovelli says [to me] in a 2008 paper : maybe we don't understand what QM is telling us because we don't have a valid starting point. Keep in mind his paper is a set of ideas rather...

Isaac, I wish I had your knowledge when I was 13. WELL DONE! Keeping in mind all the above reasons why the two theories do 'work' in their own domains and are 'tested' rather than 'proved', here is a perspective that is somewhat different than those posted. Here are some reasons why some...
