An ancient Eastern philosophy posits that the universe originated from nothingness, from which two opposing yet unified elements that constitute all things originated. Inspired by this philosophy, this article proposes that the universe is composed of two fundamental particles: Yin and Yang particle. The vacuum, in this context, consists of vacuum quanta, which are formed by the combination of Yin and Yang particles. The separation of these particles results in light and matter, while their combination constitutes vacuum quanta. The attributes of Yin and Yang particles are inherently opposite. The Yin particle is invisible, whereas the Yang particle is visible. Additionally, the Yin particle has a positive charge, while the Yang particle has a negative charge. Similar to electrons, Yin and Yang repel like charges and attract opposite charges, which is the basis of the force of electric charge. Electrons themselves are also composed of Yin and Yang particles. When Yin and Yang particles separate from a vacuum quantum, a “hole” is left behind. The concept of a hole here is similar to Dirac's theory of electrons and positrons[1]. A hole represents the opposite state of a vacuum quantum: while the vacuum is “calm”, the hole is “greedy”. This greed creates an attractive force that pulls in everything, including Yin and Yang particles, as well as other holes. Therefore, the holes described in this theory are analogous to black holes, which are the sources of gravitational force. Schrodinger’s wave function equation, a complex function involving real and imaginary numbers, is reinterpreted in this article. It is hypothesized that the real number corresponds to the visible Yang particle, while the imaginary number corresponds to the invisible Yin particle. The following sections explain various physical phenomena through the lens of the Yin–Yang particles theory.
