The Hubble constant has been added in addition to the three fundamental constants (speed of light, gravitational constant and Planck constant) used by Max Planck, for derivation of the Planck mass by dimensional analysis. As a result, a general solution is found for the mass dimension expression m = γ p m 0, where m 0 ≡ m p is the Planck mass, γ = 1.23×10−61 is a small dimensionless quantity and p is an arbitrary parameter in the interval [-1, 1]. The Planck mass m p = 2.17×10 -8 kg, mass of the Hubble sphere M H ~ 10 53 kg, minimum quantum of mass/energy m G = 2.68×10-69 kg,Weinberg mass m W = 1.08×10 -28 kg, mass of hypothetical quantum gravity atom M G = 3.8×10 12 kg, Eddington mass limit of stars M E = 6.6×10 32 kg and some more masses potentially important for the physics and astrophysics represent particular solutions for values of p, expressed as fractions with small numerators and nominators.

This paper is a revisit to a 2011 document, with the addition of results pertinent to singularities in the case of a single repeating universe, as well as when the multiverse voids the necessity of a classical GR singularity. When a classical singularity does not exist, it impacts the formation of a massive graviton for reasons brought up, and allows for reacceleration of the universe due to massive gravitons. The existence of massive gravitons would also affect initial entropy, and also lead to the datum, that a calculated inflaton φ(t) may re-emerge after fading out in the aftermath of inflation. The inflaton may be a contributing factor, with non-zero graviton mass, in reacceleration of the universe a billion years ago. The inflaton is a source of reacceleration of the universe, especially if the effects of a re-emergent inflaton are in tandem with the appearance of macro effects of a small graviton mass, leading to a speed up of the rate of expansion of the universe one billion years ago, at red shift value of Z ~ 0.423. We find that the graviton being massless or massive directly affects graviton contributions to reacceleration of the universe, with other phenomenological consequences. Finally we give our own counterpart as to how much space-time should be transferred to the present cosmological inflationary cycle which may permit preservation of Planks constant value and support Corda's brilliant "gravity's breath" document.

“…The characteristic distance we will obtain the well known expression for cross section of two-photon quasiparticles annihilations [10] in which m will replaced to 3m . In non-relativistic limit for probability of this process we will obtain the formula is very small mass that was call the "Hubble mass" [13].…”

The model in which expansion of the Universe leads to a generation of non-equilibrium vacuum-like electron-positron plasma is proposed and researched. The formulas that relate the Hubble's constant with the concentration of plasma particles and the cosmological constant are obtained. The collective properties of vacuum-like plasma are investigated. It is shown, that the coefficient of a two-photon annihilation in such plasma is nine times less than for the free particles. A simple formula for dark energy density as a function of electron mass and charge is obtained. It was demonstrated that acceleration of plasma's chemical potential fluctuations flow proportional of dark energy density.
