  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, one can perhaps derive the exact stage of the current universe.
