Positively massive existence exhibits gravitating interactions, while negatively massive existence exhibits anti-gravitational interactions. Here, “existence” encompasses both massive and energetic forms in the universe.
On a large cosmological scale, effective mass can be expressed as follows:
The traditional Cosmological view:
Mᵉᶠᶠ = Mɢ = Mᴍ + Mᴅᴇ
The Extended Classical Mechanics (ECM) view.
Mᵉᶠᶠ = Mɢ = Mᴍ − Mᵃᵖᵖ
The primordial universe existed purely in energetic, vibrational form, without massive particles. Even then, this energetic existence possessed a potential form corresponding to an effective mass Mᵉᶠᶠ, with an associated gravitating mass Mɢ < 0.
Thus, the universe as a whole manifests both negative gravitational mass Mɢ < 0 and positive gravitating mass Mɢ > 0, corresponding to a balance between positive effective mass Mᵉᶠᶠ > 0 and negative effective mass Mᵉᶠᶠ < 0. Here, Mᵉᶠᶠ > 0 represents the mass contributing to gravitation, while Mᵉᶠᶠ < 0 represents the antigravitational mass of the universe.
Both effective gravitational and antigravitational masses vary dynamically depending on motion and gravitational interactions.
Currently, the effective negative gravitational mass associated with dark energy constitutes approximately 72% of the universe, whereas the effective positive gravitational mass constitutes less than 5%. Consequently, dark energy’s negative mass dominates the large-scale dynamics of the universe.
Moreover, the observed accelerated expansion of the universe indicates that the negative effective mass of dark energy is increasing. It is plausible that the universe will reach a state where the influence of positive effective mass becomes negligible, due to the continued accelerated expansion and the corresponding decrease in effective positive gravitational mass density.
Therefore, dark energy, in fact, is increasing.
