  We use a root finder procedure to obtain 
  <img src="Edit_1b92105a-3def-42b1-9d85-d0d8751ee379.bmp" alt="" /> . We use an inflaton value due to use of a scale factor 
  <img src="Edit_07cfc0f5-1e6a-44a9-b37b-54fc55bdafbc.bmp" alt="" /> if we furthermore use 
  <img src="Edit_980c2f2d-ae0d-4931-a0ed-b16d044cfa29.bmp" alt="" /> as the variation of the time component of the metric tensor in Pre-Planckian Space-time up to the Planckian space-time initial values. In doing so, it concludes with very restricted limit values for 
  <img src="Edit_1681c5aa-ebd2-4630-a8fb-e2c8c3f8e73a.bmp" alt="" /> of the order of less than Planck time, leading to an enormous value for the initial Cosmological constant.
