Quasi-Steady State Cosmology
Modern cosmology began with the realization that there were solutions to Einstein’s theory of gravity discovered by Friedmann and Lemaitre which when combined with the redshift distance relation of Hubble and others could be interpreted as showing that we live in an expanding universe. It was then only elementary logic to argue that if time reversal was applied, the universe must originally hav...
متن کاملThe quasi-steady-state cosmology
This paper outlines an alternative cosmology called the quasi-steady-state cosmology (QSSC) which was proposed in 1993 as a rival to the standard big bang cosmology (SBBC). The motivation for an alternative cosmology is introduced by first discussing some of the weak points of the SBBC. The theoretical framework and observational tests of the QSSC are next described. Finally some tests which ca...
متن کاملDetermining “small parameters” for quasi-steady state
For a parameter-dependent system of ordinary differential equations we present a systematic approach to the determination of parameter values near which singular perturbation scenarios (in the sense of Tikhonov and Fenichel) arise. We call these special values Tikhonov parameter values. The principal application we intend is to equations that describe chemical reactions, in the context of quasi...
متن کاملComments on the Quasi-Steady-State Cosmology
The Quasi-Steady-State Cosmology as proposed by Hoyle, Burbidge and Narlikar does not fit the observed facts of the Universe. In particular, it predicts that 75-90% of the radio sources in the brightest sample that shows steeper than Euclidean source counts should be blueshifted.
متن کاملSteady quasi-homogeneous granular gas state
Using Newtonian molecular dynamics we study a gas of inelastic hard disks subject to shear between two planar parallel thermal walls. The system behaves like a Couette flow and it is tuned to produce a steady state that ideally has uniform temperature, uniform density, no energy flux and a linear velocity profile for restitution coefficient in the wide range: 0:3prp1. It is shown that Navier–St...
