Abstract We use standard general relativity to illustrate and clarify several common misconceptions about the expansion of the universe. To show the abundance of these misconceptions we cite numerous misleading, or easily misinterpreted, statements in the literature. In the context of the new standard ΛCDM cosmology we point out confusions regarding the particle horizon, the event horizon, the ‘observable universe’ and the Hubble sphere (distance at which recession velocity = c). We show that…

Interpretation of the cosmological metric
The cosmological Robertson–Walker metric of general relativity is often said to have the consequences that (1) the recessional velocity v of a galaxy at proper distance l obeys the Hubble law v=Hl,…
An Interpretation of Milne Cosmology
The cosmological concordance model is consistent with all available observational data, including the apparent distance and redshift relationship for distant supernovae, but it is curious how the…

Abstract Based on the magnitude–redshift diagram for the sample of supernovae Ia analyzed by Perlmutter et al. (1999), Davis & Lineweaver (2004) ruled out the special relativistic interpretation of…
Cosmological Expansion Rate–Various Measurement Results and Interpretation
Different values of the Hubble constant for extragalactic objects are not considered here. We give a number of examples of the extreme accordance of expansion rates of different fields of knowledge…
Beyond the concordance cosmology
For almost a hundred years now, Einstein’s General Relativity theory has played a pivotal role in our understanding of the Universe. The recent realization of the accelerated cosmic expansion,…
Photon geodesics in Friedmann–Robertson–Walker cosmologies
The Hubble radius is a particular manifestation of the Universe’s gravitational horizon, Rh(t0) ≡c/H0, the distance beyond which physical processes remain unobservable to us at the present epoch.…
The kinematic origin of the cosmological redshift
A common belief about big-bang cosmology is that the cosmological redshift cannot be properly viewed as a Doppler shift (that is, as evidence for a recession velocity) but must be viewed in terms of…
Conceptual Problems of the Standard Cosmological Model
The physics of the expansion of the universe is still a poorly studied subject of the standard cosmological model. This because the concept of expanding space can not be tested in the laboratory and…
Photon Geodesics in FRW Cosmologies
The Hubble radius is a particular manifestation of the Universe’s gravitational horizon, Rh(t0) ≡ c/H0, the distance beyond which physical processes remain unobservable to us at the present epoch.…
The “writing on the cosmic wall”: Is there a straightforward explanation of the cosmic microwave background?
The Cosmic Microwave Background (CMB) is taken today as reflecting the thermodynamical state of the universe at these early cosmic times. Based on this assumption and standard cosmological principles…

Dark Energy and the Observable Universe
We consider ever-expanding big bang models with a cosmological constant, Λ, and investigate in detail the evolution of the observable part of the universe. We also discuss quintessence models from…
Solutions to the tethered galaxy problem in an expanding universe and the observation of receding blueshifted objects
We use the dynamics of a galaxy, set up initially at a constant proper distance from an observer, to derive and illustrate two counter-intuitive general relativistic results. Although the galaxy does…

OBSERVATION OF COSMOLOGICAL TIME DILATION USING TYPE IA SUPERNOVAE AS CLOCKS The Supernova Cosmology Project : III
This work is based on the first results from a systematic search for high redshift Type Ia supernovae. Using filters in the R-band we discovered seven such SNe, with redshift z = 0.3 — 0.5, before or…
Time Dilation in the Light Curve of the Distant Type Ia Supernova SN 1995K
The light curve of a distant Type Ia supernova acts like a clock that can be used to test the expansion of the universe. SN 1995K, at a spectroscopic redshift of z = 0.479, provides one of the first…
Dynamical solutions to the horizon and flatness problems.
TLDR
Because superluminal expansion and entropy production are the two generic features of inflationary models, the results suggest that inflation, or something very similar, may be the only dynamical solution to the horizon and flatness problems.
Spectroscopic identification of a galaxy at a probable redshift of z = 6.68
