摘要 : In this article, based on the wave equation established in the first part of this series, I have studied the evolution of the energy density of the universe from the initial moment to the present, and found that there is still residual energy of the initial energy of the universe, which appears in the form of vacuum energy. The residual energy is the simplest explanation for dark matter. The calculations show that the present average energy of each momentum mode in the residual energy is of the order of 10^{-3} eV, which is approximately 3 to 5 times the averaged energy of photons in the cosmic microwave background.
