1. Basics, i.e. Roberson Walker Metric, Hubble Parameter, and Initial Density
We start off with using the Roberson Walker metric, i.e. using  and in doing so, referencing page 74 of  we have that if we access using R as the radius of a 3 sphere, in the Line metric, for the Roberson-Walker formulation, as well as a fixed volume of space, occupied cosmologically after a world line time, t, as
Here, is a scale factor, with the scale factor = 1 in the present era, and being as low as 10 - 55 in Planck time regimes. If so then, if we speculate upon a density drop off, given phenomenologically by
And, then use of the evolution Equation (3), on the LHS, the time derivative of density, as given by
As well as looking at the generalized Chapyron Gas model for DM and DE  given as
Then the density function for space time, as referenced in Equation (2) has an initial value of the form, if the volume is proportional to the cube of Planck length, , then we will write, to first approximation, where A = 1/3 by the radiation regime of space-time. Here we are assuming an invariant for the cosmological constant, with its value in early time the same as today, i.e. no Quintessence
The rest of this document will use a derivation by the author modified HUP  as to this Equation (5).
2. Basic Background on the Heisenberg Uncertainty Principle, as Used by This Document
If we use the following, from the Roberson-Walker metric     .
Following Unruh   , write then, an uncertainty of metric tensor as, with the following inputs
Then, the surviving version of Equation (6) and Equation (7) is, then, if    
Equation (9) is such that we can extract, up to a point the HUP principle for uncertainty in time and energy, with one very large caveat added, namely if we use the fluid approximation of space-time 
Then by 
Then, by 
3. Estimating of the Term in Equation (12), as the Conclusion, with Consequences
The summary of what we obtain here, is if
For our purposes, this corresponds to having fairly large but not infinite, but also the decisive factor in the reduction of energy density as given in Equation (2), i.e. that even in the Pre Planckian regime, that we position the energy density for a dramatic drop in value. We do this preparation for a reduction in the energy density so that the value of is very small and consistent with  . And also, what we are referring to as a phase shift, as for a change of state in the HUP, as delineated below:
This matter of Octonionic and Pre Octonionic is being pursued separately by the author, but the notice of a phase shift, is in work which is consistent with work which Dr. Li and Dr. Yang did, in  and the reader can access Octonionic and Pre Octonionic states by the following:
Keep in mind one basic fact. If we restrict ourselves solely to Octonionic geometry, we are embedded deeply in only what the Standard Model of physics allows. We should though understand what is implied by the physics of the Octonionic structure and so the rest of this first discussion is devoted to it.
In  , Wilson gives a generalized structure as to Octonionic geometry, and it is a generalized way to introduce higher level geometry into the formation of standard model physics. Crowell, in  examines its applications as to presumed space-time structure. Also note what is said in  the take away from it, is that as quoted from  , that there exists
(A linkage to the) mathematics of the division algebras and the Standard Model of quarks and leptons with U (1) × SU (2) × SU (3) gauge fields.
End of quote:
Once again, if we have only U (1) × SU (2) × SU (3) gauge fields, we have only the standard model, and that if we wish to have a minimum time step, we need to go beyond the standard model.
The division algebras are linked to Octonionic structure in a way which is touched upon by Crowell  , but the main take away is that in the Pre-Planckian space-time regime, that there was specific inputs which may explain some of the findings of  from a different perspective. As well as  , it is worth reading, i.e. the reader,  as well as Reference  for Baez’s summary as to the properties of Octonions as well. We also claim that resolution of these details will be important in falsification of the argument given in  as well. The uncertain principle as utilized can be checked against the generalized HUP as given in  , and if or not a phase shift in early universe signals, GW, or what have you as given in  occurs, may give insight as to if there are extra dimensions as alleged in  .
It is worth reviewing if this construction meets the experimental gravitational tests mentioned in  by Abbot et al. of LIGO which started experimental gravitational astronomy. Furthermore, the considerations of Octonionic space-time theory should be checked against the experimental tests mentioned by Corda, in  which could confirm or falsify different gravitational theoretical models. In addition, this can be further refined by the 2nd Abbot paper,  which did a different mass range of black hole binary, as of  .
In addition, all these can be used to also vet if  , by Penrose, i.e. cyclic conformal cosmology, as written, is ruled out or confirmed by various experimental and modeling tests.
