Fermi Degenerate Antineutrino Star Model of Dark Energy

Abstract

When the Large Hadron Collider resumes operations in 2021, several experiments will directly measure the motion of antihydrogen in free fall for the first time. Our current understanding of the universe is not yet fully prepared for the possibility that antimatter has negative gravitational mass. This paper proposes a model of cosmology, where the state of high energy density of the big bang is created by the collapse of an antineutrino star that has exceeded its Chandrasekhar limit. To allow the first neutrino stars and antineutrino stars to form naturally from an initial quantum vacuum state, it helps to assume that antimatter has negative gravitational mass. This assumption may also be helpful to identify dark energy. The degenerate remnant of an antineutrino star can today have an average mass density that is similar to the dark energy density of the ΛCDM model. When in hydrostatic equilibrium, this antineutrino star remnant can emit isothermal cosmic microwave background radiation and accelerate matter radially. This model and the ΛCDM model are in similar quantitative agreement with supernova distance measurements. Therefore, this model is useful as a purely academic exercise and as preparation for possible future discoveries.

A higher dimensional cosmological model for the search of dark energy source

“…The explanation of a physical mechanism as a source of DE can be seen in [14]. A cosmological model involving an antineutrino star is proposed in [15] in an attempt to find the origin of DE. In [16], DE is obtained from the violation of energy conservation.…”

f(R,T) Gravity Model Behaving as a Dark Energy Source

“…In [7], the authors assert that emergent D-instanton might indicate us a hint to the root of DE. A cosmological model associated with an antineutrino star is constructed by [8] in order to search the origin of DE. In [9], the author presents an explanation for DE with pure quantum mechanical method.…”
