Those "GUTs" as has introduced are known as well. However, a new physics theory has recently been established [1]. It is a brand new physical theory different from the standard model.It is a new physical theory based on high-dimensional space (five dimensions) that combines relativity with quantum mechanics. This theory suggests that there are only four independent physical constants in nature (vacuum dielectric constant, vacuum speed of light, Planck's constant, and light base radius), and most other physical constants such as basic charge, electron mass, proton mass, electron radius, proton radius, and gravitational constant are related to them and theoretically calculated from them. All things in nature are determined by the properties of vacuum. The four fields (forces) in nature, including universal gravitation, are unified by the same electromagnetic force without the need for high-energy conditions. Theoretical calculations have concluded that any fundamental particle with mass in nature must carry an integer charge (either positive or negative). There is no fundamental particle with only a rest mass but no charge, or no fundamental particle with only a charge but no rest mass; and there is no fractional charge present. Mass and charge are two external manifestations of the existence of a thing. Solving the theoretical equation only provides two solutions, leading to the conclusion that only two types of particles, electrons and protons, exist stably in nature, while other fundamental particles only exist at energy due to vacuum fluctuations. In five dimensional space, electrons and protons are completely symmetrical and antiparticles to each other. The difference between electrons and protons we see is due to the three-dimensional perspective of reality. Neutrons are complexes of electrons and protons, and their radii are slightly larger than those of electrons, while protons have very small radii, which are four orders of magnitude smaller than electrons. The charge, mass, and radius of electrons and protons can be calculated theoretically.
