According to the present investigation, the energy (Mc2) of the Cosmic Globe is a kinetic expression of its Potential Energy (P. E.) in the Vacuum Field (V-Field). It is above the Zero Point Energy (ZPE) of the Vo-Field and due to its dynamic nature expands isotropically in the surrounding Vacuum, increasing the size of the Cosmic Globe. But the progress of Centrifugal Expansion is opposed by the Centripetal drag of the G-Field, which brings the expansion to a halt when the P.E. in the V-Field and the Kinetic Energy (K.E.) of the Cosmic Globe exhaust themself at Rc = Mc2 x G/c4. Instead, the G-Field P.E. attains its maximum value Rc x c4 /G = Mc2 = total mass-energy of the Cosmic Globe - which triggers the Contraction phase. Thus, Rc is the delimiting non-crossable boundary for the mass-energy expanding inside the Cosmic Globe - marking a sharp contrast with the Schwarzschild radius (Rs), which delimits the no-return boundary of the mass-energy collapsing under its g-forces! And, during the G-compression, the contracting globe squeezes out the voids and discharges its energy into the V-Field to attain its ZPE state. At the Maximum Contraction (Ro), the G-Field P.E. equals zero, while the P.E. with respect to the V-Field attains its maximum value - which initiates the Expansion Cycle. In short, the Cosmic Globe perpetuates its expansion and contraction cycle by recycling its total energy through the periodic and gradual interconversion into the P.E. of the V-Field and G-Field.
