of the universe horizon distance and universe horizon volume were investigated
in the light of five general cosmic models which were constructed in a previous
study. Both distributions increase so slowly up to t ≈ 21.5444 Myr, then they start raising very fast up to t ≈ 60 Gyr. Afterwards, they increase
again very slowly until t ≈ 124 Gyr.
Distributions of mass of radiation, matter and dark energy within the horizon
volume of the universe were also studied in the five general cosmic models. The
masses of both radiation and matter decrease gradually with time while the mass
of dark energy increases. The mass of radiation prevailed in the early universe
up to t ≈ 34627.5 - 55916.2 yr, where
it becomes equal to the mass of matter. Then the mass of matter dominated until t ≈ 9.4525 - 10.0632 Gyr, where it
becomes equal to the mass of dark energy. Thenceforward, the mass of dark
energy prevails the universe. The cosmic space becomes approximately matter
empty in the so far future of the universe.
