What areas of commonality are there between quantum theory and general relativity?

Is it even possible to use the the two when calculating the same physical behaviour?

Is there a correlation between them?

At what point does general relativity fail to work in the world of the atom and why?

    Googling "constant of Quantum Theory and General Relativity" returns zero hits. Where have you heard this? There are plenty of endeavors to reconcile the two theories, but I'm not sure what you mean by a "constant". – pela Nov 17 '15 at 07:45

    Come on chaps no need for the downvotes, Lorenzo is obviously asking what QM and GR have in common i.e. in what areas are they they same. That's a fair question. – John Rennie Nov 17 '15 at 08:38

  • Funny, just read this feature in Nature: http://www.nature.com/news/the-quantum-source-of-space-time-1.18797?WT.mc_id=TWT_NatureNews. Brings up some very interesting new things that may have something to do with your question. – udrv Nov 17 '15 at 09:22
  • GR or spacetime is essentially classical, there is probably nothing in common. however, you can use dimensional analysis to find the scale both GR and QM are critical. – Shing Nov 17 '15 at 10:08
  • Both involve gauge symmetries, albeit 2 completely unrelated ones: if the action is unchanged by a diffeomorphism, one can derive general relativity, with a few principles. Based on the symmetry of action under a particular change of wave function phase, one can derive the standard model of particle physics, explaining electric charge and basically everything we currently know for certain about – Damon Blevins Feb 26 '16 at 17:37
  • Particles. With a few issues, of course! Internal symmetries are the latter. They change the particles state, not the spatial-temporal state, unlike a diffeomorphism, which is thus called a spacetime symmetry. – Damon Blevins Feb 26 '16 at 17:38
