The Non-Thermodynamic Self-Gravitating Perfect Fluid in a Dynamic Einstein-de Sitter Metric
摘要
This chapter discusses a particular early cosmological model in which the source of Einsteinian gravitation is assumed to be a “cold collisionless gas” composed of galactic matter (i.e. a thermodynamically inert, spatially homogeneous medium) with a timelike flow given by the timelike geodesics of the Einstein-de Sitter spacetime metric tensor.
