In the same
context the dark energy is necessary to explain the expansion process of the universe [1-2].
Where, ξU = H0 = the Hubble parameter or expansion rate of the universe (H0 = ξU =70 (km/sec)/Mpc = 2.26854593 x10-18s-1), ρu = dislocation density (ρu = 1.273x1011 dislocations/m 2).
By using the Eq. (2) and Eq. (3) ξP = c/λP = 1.850570728x10 43s-1, this frequency factor represents the expansion rate of the cosmic structure at MPS.

The adiabatic charge transition levels between q and q + 1 charge states of a single defect can be
calculated via the following expression
Eq+1/q = Eqtot − Eq+1
tot + ∆V (q) − ∆V (q + 1), (1)
where Eqtot and Eq+1
tot stand for the total energies of the system in the q and q + 1 charge state,
respectively.
