In the present paper the theoretical method of descending from the concrete to the abstract is applied to the evolution of elementary particles in the early universe, and a corrected and concretized research program for the primordial universe is given. We obtain through temporal vertical abstraction the following concrete evolutionary phases: 1. Gravitons and bound photons in the primordial universe up to the Big Bang, 2. Free photons of the cosmic background radiation in the universe after the Big Bang, 3. The simplest building blocks of matter in the universe after pair creation. The physical process in these three evolutionary phases is concretely described. The physical theories corresponding to the three evolutionary phases are – in the global area: a general-relativistic, hydrodynamic theory of gravity and in the local area: a relativistic, hydrodynamic quantum theory (= quantum hydrodynamics). The interplay of these two physical theories to determine the gravitational quantum hydrodynamic total state of the primordial universe is presented in detail in the form of a research program.
