We use a quantum tunnelling equation as given by V. Balck in the proceedings “Relativity and Gravitation, 100 years after Einstein in Prague” to delineate a relationship between spatial dimensions, and energy. Afterwards, we then scale the energy as related to formation of primordial black holes, in the onset of the big bang, and how they decay, to evaluate graviton production, and by extension graviton ‘particle’ induced entropy. The first section affirms that in principle we may have far fewer dimensions than was deemed necessary in string theory. In doing so, we compare the results with earlier work done where we used an argument by Haggard and Rovelli as far as the introduction of quantum effects, in the early universe. Note that Haggard and Rovelli delineated an outer radius as to the range of quantum effects, which extends past the Schwartzshield radius This is defined as 7/3 times the mass of the initial cosmological system. We also have a range of perturbative effects as delineated by Turok’s article which gives a range of values
