Calculating δgtt at Boundary of Start of Planckian Physics Due to 1 Million Relic Black Holes


We use the ideas of a million black holes, at the boundary of contribution to the shift from Pre-Planckian to Planckian physics, as a summed up contribution from one million primordial black holes. I.e. this is assuming a quantum bounce. This is an extension of work done by the author as to explain the nature of a transition from being tiny to when becomes 1 in value. Taking this into account, this article is a way to delineate the physics, inherent in the transition from to which puts a premium upon the growth of the inflaton, due to , with but with changing from , an 10255 increase in magnitude. This increase in magnitude may be the driver of subsequent inflation. When we have a pre quantum, especially if the inequality becomes an equality, and then the transition to marks the start of quantum gravity, whereas our black hole entropy model used to obtain a non zero entropy contribution from 1 million primordial relic black holes, as referenced, comes from Dr. Sen in an October 10 Run Run Shaw lecture in Stonybrook University.

1. Introduction

Dr. Sen, in 2016 [1] makes use of a simple black hole generation of entropy analogy which we write as, using Planck units for 3 + 1 dimensional geometry


N, in this case, is a counting mechanism, for “particles” leaving the event horizon of a black hole and we will have more to say about an alleged counting mechanism later, while r, in this case, is a radial “distance” which is assuming a nonsingular treatment with r, in this case equivalent to an event horizon [2] [3] . We will though for the sake of a model, state that we are fixing say 106 (a million) relic black holes, at the boundary of Pre Planckian to Planckian physics. And that we are when doing that, making the following transformation, as given by [4]


The idea of a 2nd order transition in cosmology can be looked up in [5] [6] [7] but in fact what we are examining is due to [3] , namely if we are looking at the generation of gravitational waves/gravitons from decay of the following mass via


Take about 1 million black holes behaving as given in Equation (3) and also assume, [8] , i.e. a quantum bounce, with [8]


And we will be using in Equation (2)


In addition, from [9] we will be using the following for the inflaton, if, then



Furthermore, Sciama, in 1982 [10] allows us to write the following, namely Sciama [10] in 1982 argued for the lifetime of a black hole, of mass M, that the following holds


Here, if the time is about 10−44 seconds (Planck time), then. If so, then, according to [2] , Calmert, et al. about 0.1% of the energy emitted, in the traditional 4 dimensional black hole (3 + 1 dimensions) would be gravitons. Then, becomes linked to Gravitons according to


This would mean then 1 primordial black hole would produce, if the mass of a graviton is 10−62 grams [11]


Or, for a million black holes about 1058 gravitons and we would, do the following for change in energy, namely write, from [2] , and using [4]


Furthermore, we will be assuming, using for Graviton production, that, i.e. the Planck length is approximately the same as the event Horizon of the Black hole, that then we will use Equation (1) directly with the result that for 3 + 1 dimensions, we are using if we use Planck length, that


For the remainder of this document we will be working with


We will be working with Equation (13) to isolate out what we can extract from this, in terms of early universe conditions. The approximation for Gravitons and entropy is based upon, Ng, namely we will, as a start, incorporate Ng’s infinite quantum statistics idea, of entropy being equivalent to a count of particles, i.e. by [12]


All this will be elaborated upon in the main analysis leading to the change in inflaton values, next.

2. Isolation of the Value of the Inflaton, Using Equation (13), Equation (14)

Given the above, we can write, if we do the math, that we need to do a basic re normalization via Planck units of the above in terms of, if so then we have that we rewrite Equation (13) via


Then if we can rewrite the Equation (13). To read as follows. If the mass of a graviton is 1062 g, and the value of Planck mass is about 10−5 g with Planck mass renormalized by Planck scaling to be 1, then in the Planck rescaling we have


Now if the frequency, initially was of the order of


We get, then that


i.e. the inflaton, nearly zero, in the Pre-Planckian regime, becomes enormously large, right after the phase transition, and we are assuming that the scale factor, is invariant, in Equation (18). If so then there is a 10255 increase in the inflaton, according to Equation (18).

3. Conclusion: Is the Increase of 10255 for the Inflaton, a Driver of Inflation?

The final question to ask, is about the N in the right hand side of Equation (1). It can be viewed, as say the number of operations, for the Universe. i.e. in this sense is a counter point to the [19] of Seth Lloyd which has a power relationship of the entropy being 3/4th the power of the computational bits. i.e. our suggestion is that perhaps there are many more N computations than was supposed in Seth Lloyds [19] reference.
