Abstract: We investigate the effects of Quantum Gravity on the Planck era of theuniverse. In particular, using different versions of the GeneralizedUncertainty Principle and under specific conditions we find that the mainPlanck quantities such as the Planck time, length, mass and energy becomelarger by a factor of order 10-10^{4} compared to those quantities which resultfrom the Heisenberg Uncertainty Principle. However, we prove that thedimensionless entropy enclosed in the cosmological horizon at the Planck timeremains unchanged. These results, though preliminary, indicate that we shouldanticipate modifications in the set-up of cosmology since changes in the Planckera will be inherited even to the late universe through the framework ofQuantum Gravity or Quantum Field Theory which utilizes the Planck scale as afundamental one. More importantly, these corrections will not affect theentropic content of the universe at the Planck time which is a crucial elementfor one of the basic principles of Quantum Gravity named Holographic Principle.
