On the effective inertial mass density of a dissipative fluid

TL;DR

This paper demonstrates that the effective inertial mass density of a dissipative fluid decreases shortly after leaving equilibrium, influenced by dissipative variables, with implications for cosmology and astrophysics.

Contribution

It introduces a new understanding of how dissipative processes affect inertial mass density immediately after equilibrium is disturbed.

Findings

Inertial mass density reduces by a factor depending on dissipative variables.

Reduction occurs on a time scale of the order of relaxation time.

Potential applications in cosmological and astrophysical models.

Abstract

It is shown that the effective inertial mass density of a dissipative fluid just after leaving the equilibrium, on a time scale of the order of relaxation time, reduces by a factor which depends on dissipative variables. Prospective applications of this result to cosmological and astrophysical scenarios are discussed.
