Analyzing Phantom Energy Ascribable to the Ultimate Fate of the Cosmos in Connection to Big Rip Cosmology in Relativistic Cosmology

Dark energy is a hypothetical form of energy that has been unremittingly applying force on the cosmos in every permissible direction.Astrophysicists and space scientists have been persistently investigating about the ultimate fate of the cosmos with the progress and several revolutionary presumptions articulated on the subject arena of Relativistic Cosmology.Since dark energy is extremely responsible for the exponential expansion incurred in the cosmos, therefore the space researchers have been persuading the concept that in far future the shape of the observable cosmos is tending to be flat, at the similar instance also builds a privilege whether the cosmos in the long run will on the verge of re-collapse and finish off with a colossal pulverization.Phantom energy is a hypothetical form of dark energy, possessing negative kinetic energy and satisfying the equation of state ‫‬ = ‫ܿߩ߱‬ 2 with ߱ < -1 where the dimensionless parameter ߱ has been acknowledged as the Equation of State (EoS) parameter, ‫‬ represents pressure, ‫ߩ‬ stands for the density of the fluid and ܿ is the velocity of light waves in vacuum.Here in this present study, an investigation has been portrayed regarding the vivid scenarios experienced whenever the subsistence of dark energy in the cosmos is under the governance of phantom dominance era satisfying the condition that the summation of the two physical measures viz., the pressure and energy density lead to a negative quantity.With a specified predetermined time span, the value of the positively aggrandized phantom-energy density grows to be infinite in spite of the subsistence of any cosmic matter in the cosmos.At long last, the phantom energy escalates the 36 Pallavi Saikia and Dr. Man Mohan Jha cosmic repulsion or detaching away of the interstellar objects like the constituents of the solar system, the galaxy clusters, the Milky Way, the mere fundamentals of an atom before the cosmos experiences a Big Rip Cosmological spectacle or an eminent annihilation.
