The cosmic implication of dark energy manifestation is an important topic in today's astro-physics. It is again a burning issue that the vacuum field with its gargantuan energy density is posing to be a misfit to rationalize the observably introduced dark energy to interpret the speeded expansion of the flat space containing the critical density of gravitationally active energy (matter equivalent density of 1x10^(-26) kg m^-3. However, the critical energy density of this space requires a miniscule fraction of the vacuum energy density (one in ten to the power of 122) to impart the critical repulsive effect for speeding up space expansion against the inward pull by gravity. In view of the stated issue, introspection is made by this author on the possible mitigating path of the omnipresent vacuum field in the nonstationary space evolution with the observable expansion characteristics, namely, the angular velocity (Hubble's constant) and the recently reported angular acceleration. Presented analysis reveals that the nonlocally mitigating parameter is of similar nature as that noted in the nonstationary evolution in electrodynamics. The similarity helped in establishing the scaling down principle in the nonlocal mitigation of the vacuum field in the space evolution. Relation connecting angular acceleration of the gravitationally active space with the vacuum field characteristics could be established, which asserts the need of manifestation of dark energy and in turn estimates the reportedly arrived dark energy proportion of the universe. The present estimate of 74% dark energy content is quite close to the reported value of 68.3%. Furthermore, noting that the mitigation process essentially involves dilution of gravitationally active space with the vacuum field, thermodynamic process could be set up to reevaluate the dark energy purely from the expansion characteristics. It is show that the spontaneous dilution process leads to the manifestations of dark energy and dark matter in the expanding space. This way of estimation finally yields about 71% dark energy content. The two approaches provide quite consistent results. Analysis of vacuum field characteristics again suggests that dark energy is to dark matter ratio should be the constant, pi (~3.14). Noting the reported normal matter content of about 5%, the indicated ratio of dark energy is to dark matter corroborates to about 71% dark energy content.of the universe. By drawing similitude of the nonlocal mitigation in nonstationary evolution in electrodynamics the ratio of dark energy is to dark matter could be shown to have the value of pi (~3.14). It proves universality of the nonlocal interaction irrespective of the type of perturbation that causes the nonstationary evolution. See pdf files 1.
