Abstract:
A theory explaining the non-observation of the dark matter and the source of the dark energy is presented in this letter. By integrating the asymmetrical potential and the Higgs potential, we provide a model with instantaneous symmetrical breaking and stable symmetrical breaking, resulting in the non-observed dark matter and observed matter respectively. Two crucial parameters in this model are the frequency and strength of the symmetry breaking from the vacuum: the former helps explain the impact of the effective mass from the dark matter; the latter determines the source of the dark energy. The expected strength in a certain period varies, causing the accelerating or deccelerating expansions of the universe. Considering the expected strength correlated with the vacuum expectation value and basing on the possible variations of the measured masses of the fundamental particles such as Z boson over time, current universe.
