The Planck Constant Was Not a Universal Constant

According to traditional classical quantum theory, due to the prior existence of the Planck constant, considered a universal constant, it is thought that the energy of a photon can be determined if its frequency is known, and the wavelength of a quantum can be determined if its momentum is known (E = hv and λ = h/p). In this paper, however, the Planck constant only comes into existence when mecλC is replaced with h. There is no problem with introducing h to simplify equations, but quantum mechanics is not affected even if there is no symbol h. The physicists at the beginning of the 20th century overestimated the Planck constant, and this gave rise to universal constants that do not exist in the natural world in itself.
