文摘While the pressureless dust assumption has been widely adopted in the standard model of cosmology, a quantitative estimate of the actual contributions of the baryonic matter and the hot/cold dark matter to the age of the Universe has not yet been made in literature. They provide a simple scenario of how the solution, e.g. the age of the Universe, is affected by the inclusion of the thermal pressure of the baryon and dark matter particles.
