Quantum non-gravity and stellar collapse Barceló, Carlos Garay Elizondo, Luis Javier Jannes, Gil Observational indications combined with analyses of analogue and emergent gravity in condensed matter systems support the possibility that there might be two distinct energy scales related to quantum gravity: the scale that sets the onset of quantum gravitational effects E-B ( related to the Planck scale) and the much higher scale E-L signalling the breaking of Lorentz symmetry. We suggest a natural interpretation for these two scales: E-L is the energy scale below which a special relativistic spacetime emerges, E-B is the scale below which this spacetime geometry becomes curved. This implies that the first 'quantum' gravitational effect around E-B could simply be that gravity is progressively switched off, leaving an effective Minkowski quantum field theory up to much higher energies of the order of E-L. This scenario may have important consequences for gravitational collapse, inasmuch as it opens up new possibilities for the final state of stellar collapse other than an evaporating black hole. 2023-06-20T03:49:48Z 2023-06-20T03:49:48Z 2023-06-20T03:49:48Z 2011 journal article https://hdl.handle.net/20.500.14352/44517 0015-9018 10.1007/s10701-011-9577-9 spa FIS2008-06078-C03-01 FIS2008-06078-C03-03 FQM2288 FQM219 Barceló, C., L.
