“…That said, the results are not spectacularly convincing at first sight with 2.59 in the "R band" which a cynic may say is more like "splitting the difference" between the two models rather than distinguishing between them. To resolve the issue Lerner et al [10] looked at the UV surface brightness of galaxies from the local Universe to z ~ 5 using the HUDF and GALEX datasets. They concluded "that available observations of galactic SB are consistent with a static Euclidean model of the Universe.…”

New data from FRB's have provided an exciting new window on the cosmos. For the first time we have both Dispersion Measure (DM) from distant sources and their redshift. This gives us the opportunity to determine the average electron number density in intergalactic space and thus test New Tired Light predictions. Here, in an alternative cosmology, the universe is static and redshifts are produced by an interaction between photons and the electrons in the intergalactic medium. In a paper published in summer 2006 New Tired Light (NTL) predicted an average electron number density of n = 0.5 m −3. In 2016 a paper was published reporting that for the first time the DM of a FRB and the redshift of the host galaxy had been found. Using standard physics this confirmed the electron number density as n = 0.5 m −3. The prediction NTL made ten years earlier was proved to be correct. Using this measured electron number density enabled a definitive value of the Hubble constant to be made by New Tired Light and the value is 63 km/s per Mpc which compares well with currently accepted values. Importantly, since in NTL the redshift and dispersion are both due to the electrons in IG space, a relationship between DM's and redshift can be predicted. NTL predicts that DM and LN(1 + z) will be directly proportional and related by the formula DM = m e c/2hr e (3.086 × 10 22 ) where m e , r e are the rest mass and classical radius of the electron, c is the speed of light in a vacuum and h is the plank constant. The numerical term is to change units from pccm it is emitted as a secondary photon that photon will have a wavelength of 2.2 mmthe wavelength at which the CMB curve peaks.

This paper describes the detail calculations of expected redshift change in the galaxies' or other distant objects' light after a certain amount of time between observations has elapsed. The detection of this phenomenon has been proposed since the Hubble's discovery of the galaxies' redshift dependence on their distance from Earth and their significant recession velocities. Various astrophysicists have performed such calculations for several cosmological models of the Universe, but not for the model introduced by the author of this paper. This is now addressed in this publication. Keywords: galaxy redshift change in time, finite size model of the Universe, Big Bang theory, gravitational redshift, Doppler redshift, Hubble constant, deformable dark matter, cosmological gravitational potential, gamma ray bursts, CMBR temperature IntroductionSeveral astrophysicists have proposed the measurement of change in the galaxies' redshift with the elapsed time of observations. The most comprehensive and early evaluation of this phenomenon was published by Sandage (1962Sandage ( , 2010 with possibly the earliest version suggested by Tolman (1930Tolman ( , 1934. Several recent publications on this subject are by Loeb (1998) and by Lerner, Falomo, and Scarpa (2015). However, all of these publications are using some variations of the classical models of the Universe based either on the main stream Big Bang (BB) model or on the Newtonian flat space model.In the previous publication Hynecek (2012a) has introduced a new model of the Universe that assumes the Universe being finite in size and filled with a repulsive and deformable Dark (transparent) Matter (DM). The DM is repulsive to visible radiating matter but attractive to itself. In this model the galaxies are treated only as small test bodies floating from the bulk of the Universe to the edge where they explode and generate the well-known immense Gamma Ray Bursts (GRB) detected here on Earth. The GRBs that are reflected back to the bulk of the Universe then contribute to the generation of new matter. This model is in line with the theory proposed by Hoyle, Burbidge & Narlikar (2000) of a steady state Universe with a constant matter creation. The new matter then condenses to stars and eventually to new galaxies endlessly repeating the cycle of creation and destruction. The galaxies' explosions residue at the edge of the Universe generates also the Cosmic Microwave Background Radiation (CMBR) with its temperature of 2.725 °K. The repulsive DM density is very small but its gravitational effects dominate the visible matter gravitation at large distances. The gravitational field of galaxies is thus compensated and screened by the DM after a certain distance. The galaxies thus for the most part move in this Universe independently of each other.The one of the significant contributions of this model to the theory of the Universe, in comparison to other models of the Universe in particular the BB model, is in the derivation of the relation between the Hubble constant and the CM...

Tests and Problems of the Standard Model in Cosmology

The main foundations of the standard ΛCDM model of cosmology are that: 1) The redshifts of the galaxies are due to the expansion of the Universe plus peculiar motions; 2) The cosmic microwave background radiation and its anisotropies derive from the high energy primordial Universe when matter and radiation became decoupled; 3) The abundance pattern of the light elements is explained in terms of primordial nucleosynthesis; and 4) The formation and evolution of galaxies can be explained only in terms of gravitation within a inflation+dark matter+dark energy scenario. Numerous tests have been carried out on these ideas and, although the standard model works pretty well in fitting many observations, there are also many data that present apparent caveats to be understood with it. In this paper, I offer a review of these tests and problems, as well as some examples of alternative models.Keywords Cosmology · Observational cosmology · Origin, formation, and abundances of the elements · dark matter · dark energy · superclusters and large-scale structure of the Universe PACS 98.80.-k · 98.80.E · 98.80.Ft · 95.35.+d · 95.36.+x · 98.65.Dx Mathematics Subject Classification (2010) 85A40 · 85-03
