The Generalized Uncertainty Principle (GUP) modifies the Heisenberg Uncertainty Principle (HUP) between position and momentum by introducing a nonzero minimum uncertainty in position. In a previous study, we demonstrated the emergence of GUP from non-extensive entropies, particularly for $S_\pm$ dependent only on the probability. In this new research, we derive a generalized energy-time uncertainty relation from these entropies. Consequently, we observe that the dispersion relation undergoes modification due to the non-extensivity introduced by the entropies $S_{+}$ and $S_{-}$. These modifications play a significant role at the Planck scale, but are negligible in the classical regime of large distances and low energies. Moreover, the modified uncertainty relation results in a maximum uncertainty in energy, attributed to the negative deformation parameter associated with entropy $S_{+}$. Conversely, the deformation parameter linked with $S_{-}$ leads to the emergence of a minimum time interval. In the Planck regime, the minimum time interval is on the order of the Planck time, while the maximum uncertainty in energy reaches the Planck energy. These findings imply that quantum gravity effects can be connected with non-extensive statistics. |
