All unidirectional energy is electromagnetic in nature. Entanglement provides optimum directional balance where two identical e-m energy systems (electron/positron, neutrino/antineutrino) possess opposing and alternating e-m directionality and interchanging identities with every e-m interaction.
There are other interactions that will result in varying degrees of directional balance, including unidirectional particles, such as
– charged particles (e.g., unidrectional energy, such as electrons, protons) that are directionally balanced by the magnetic and gravitational energy formed by the inherent energy of space,
– entangled particles with different rates of e-m interaction, resulting in partial entanglement, and partial directional balance,
– electrically neutral “mass” that is directionally balanced by gravitational energy gradients formed by the inherent energy of space.
Attraction of unidirectional or electromagnetic energy will occur whenever the interaction or proximity of two energy systems provides greater directional balance. For example, attraction occurs when two identical particles with opposing e-m directionality become entangled, resulting in alternating e-m directionality and interchanging identities with every e-m interaction, providing optimal directional balance.
Repulsion of unidirectional or electromagnetic energy will occur whenever the proximity of two energy systems provides greater unidirectionality, or directional imbalance. For example, repulsion occurs when two identical particles with the same e-m directionality (e.g., two electrons approach each other, resulting in greater unidirectionality, or when two particles, not entangled with each other, with out-of-phase alternating e-m directionality (same e-m directionality with each e-m interaction) approach each other.
Other elementary particles or particle pairs may exist at different energy levels within an atom, and do not interact directly with each other if they, themselves, are entangled with other particles, and are therefore already directionally balanced.
