Two questions about a non-flat nuclear space-time

The quest for the explanation of new or at least anomalous nuclear reactions put some authors in front of the clue, the “ansatz”, that the nuclear space-time should be no longer flat but endowed with curvature. Other authors made assumptions implying the breakdown of local Lorentz invariance at the nuclear scale. We report some suggestions aiming to check the validity of these assumptions. Given that this breakdown occurs, curvature is a case among the more general deformations of the space-time that are predicted in the deformed space-time theory.
