Description

The discovering of the Cosmic Microwave Background (CMB) radiation in the sixties
and its subsequent interpretation, the numerous experiments that followed with the
enumerable observation data they produced. We see that the energy in the form of
radiation has the equation of state p = ρ/3. This applies to all massless particles. It is
also valid for massive particles when they are moving with momenta much larger
than their masses. This is known as the extreme relativistic or ER limit opposite to
the non-relativistic or NR limit where the momenta are much smaller than the mass
of the particles. Matter in the Early Universe, from the study of isotropic of gas at
times much before the development of any structure, can be viewed as a gas of
relativistic particles in thermodynamics. To provide insight into the behaviour of
matter in early stages of the universe. The research framework mainly focuses on
discussing the basic ideas that have shaped our current understanding of the Early
Universe like the behaviour of matter under extreme conditions. We aim to discuss
cosmological observables, principles and solutions which is the physics that governs
the scope of this project specifically the relativistic thermodynamics. The simulation
and establishment of the data handling analysis work will be based on the number
density as a function of temperature, number of particles for both bosons and
fermions particles as a function of temperature using high programming language
(MATLAB). Temperature is an independent variable and time is kept as reference.
The validation of the data analysis will be compared to the cosmological solutions
the Empty de Sitter Universe, Vacuum Energy Dominated Universe, Radiation
Dominated Universe and the Matter Dominated Universe.
