\begin{abstract}
This paper contributes an extensive analysis of Dark Matter (DM) along
with associated materials regarding the interpretation of its evidence
from `cosmic microwave background radiation', `gravitational lensing',
`galactic mergers and collisions', `evolution and formation of
galaxies', `galactic clusters', `Lambda-CDM models of the observable
universe. Massive Astrophysical Compact Halo Objects (MACHOs), Weakly
Interacting Massive Particles (WIMP's), Strongly Interacting Massive
Particles (SIMPs), along with hot, warm, and cold DM, shedding an
extensive overview of the \selectlanguage{greek}γ\selectlanguage{english}\_elastic of the cold DM after the chemical
equilibrium is reached and kinetic decoupling happens earlier for
\selectlanguage{greek}γ\selectlanguage{english}\_(in-elastic) accounting for 85\% of the dominated matter in the
universe. Scaler-Vector-Tensor (SVT) Gravity, MOdified Newtonian
Dynamics (MONDs), and Gravity of Entropy (GoE) have emerged as a
supplement of the modified General Relativity (GR) as a source of
non-baryonic DM scenarios in the universe. Observable evidence has been
taken into account for the `dispersion of velocity', `galactic rotation
curves', `Lyman-\selectlanguage{greek}α \selectlanguage{english}forest simulations', '21 cm red-shift spectra',
`satellite sky surveys', `formation of structures', and `supernova
measurements of Type Ia'. Direct evidence in the underground chamber for
`nuclear giggles' either `Cryogenic experiments CRESST, CDMS' or `noble
liquid gases XENON' as a result of DM scattering via VECTOR-PORTALS and
Indirect evidence as a result of sky-surveys like satellite telescopes
ANTARES, AMANDA or through the `collider experiments' in LHC, CERN,
Geneva, Switzerland.%
