  From the observed results of the space distribution of quasars we deduced
that neutrino mass is about10^(-1) eV. The fourth stable elementary particle
(delta particle) with mass about 10^(0) eV can help explain the energy resource
mechanism in quasars, the peaks of Extra-galactic Background Light (EBL) etc.
The key is the annihilation of dark matter particles under the super-strong
gravitational/electromagnetic fields from supermassive compact celestial bodies
(SCCB) such as galactic nuclei, quasars etc. Their origin is at the early era
of the universe (EEU) as universe density lo large than lo(cr) and
lo/c^(2)=const, and physical singularities (PSs) are produced from
inflation-explosion stage. PSs can still hide in SCCB with FTL matter now. The
energy scale at lo(cr) is the critical energy E(cr). At E(cr), inner symmetries
are degenerated; below E(cr), it can hold at most 4-fold SM. Appendix is the
theoretical/phenomenal part related to the mass scales sequence (MSS),
inflation-explosion, spherical universe, BSM, new particles etc. The MSS, like
a Mendeleev's periodic table, can be used to cosmology.
