摘要: In this article, I shall propose an enlightening view on the origin of dark matter abundance, in which I introduce a neutral primordial field, which is a new field beyond the standard model. All the standard model
elementary particles are produced spontaneously from this field in the Big Bang epoch of the universe and then
these produced elementary particles decayed or annihilated in the well-known standard model interactions. The
relic of the primordial field appears in a form of vacuum energy can not only give naturally the correct abun-
dance of dark matter in the present universe, but provide a natural solution to the cosmological constant problem
as well. We find that the conventional methods of detecting dark matter either fail or have great difficulties to
detect the remaining vacuum energy of the primordial field, and how to confirm the existence of the remaining
energy of the universe’s original energy in experiment is still an open problem.
