http://www.springerlink.com/content/w6777w07xn737590/fulltext.pdf Misconceptions about the Hubble recession law Wilfred H. Sorrell, Astrophys Space Sci (2009) 323: 205211 "Many advocates of big-bang cosmology believe observations showing the dimming of distant Type Ia supernovae prove beyond reasonable doubt that the expanding universe is undergoing acceleration. It is thought that the acceleration is driven by some unknown type of dark energy. Although this standard interpretation of the supernovae data is widely accepted, it could be completely wrong. (...) The observational techniques used by Hubble led to the empirical discovery of a linear dependence of redshift on distance. Based upon these historical considerations, the first conclusion of the present study is that astronomical evidence in favor of an expanding universe is circumstantial at best. The past eight decades of astronomical observations do not necessarily support the idea of an expanding universe. This statement is the final answer to the question asked in Sect. 1 of the present study. Reber (1982) made the interesting point that Edwin Hubble was not a promoter of the expanding universe idea. Some personal communications from Hubble reveal that he thought a model universe based upon the tired-light hypothesis is more simple and less irrational than a model universe based upon an expanding space-time geometry. The second conclusion of the present study is that the model Hubble diagram for a static (tired-light) cosmology gives a good fit to the Type Ia supernova data shown in Fig. 2. This observational test of a static (tired-light) cosmology model also proves that it is wholly possible to explain the supernovae data without requiring any flat Friedmann model universe undergoing acceleration. The static cosmology does require the Andrews (2006) anomalous dimming of distant Type Ia supernovae. It is emphasized that the anomalous dimming effect has nothing to do with a particular cosmology. The anomalous dimming effect has everything to do with the intrinsic short duration of supernova light curves and the cosmic redshift of the supernova light. The intrinsic short duration of a celestial body is the key concept because the observed redshift- magnitude relation for the brightest E-type cluster galaxies do not show the anomalous dimming effect at all." Do Einsteiniana's highest priests know that the only reasonable alternative to idiotic Big Bangs, accelerated expansions of the universe etc. is the assumption that "the supposed vacuum of space is acting as an interstellar medium TO LOWER THE SPEED OF LIGHT"? They do, but for the moment that is a grand secret between them: http://www.sciscoop.com/story/2008/10/30/41323/484 "Does the apparently constant speed of light change over the vast stretches of the universe? Would our understanding of black holes, ancient supernovae, dark matter, dark energy, the origins of the universe and its ultimate fate be different if the speed of light were not constant?.....Couldn't it be that the supposed vacuum of space is acting as an interstellar medium to lower the speed of light like some cosmic swimming pool? If so, wouldn't a stick plunged into the pool appear bent as the light is refracted and won't that affect all our observations about the universe. I asked theoretical physicist Leonard Susskind, author of The Black Hole War, recently reviewed in Science Books to explain this apparent anomaly....."You are entirely right," he told me, "there are all sorts of effects on the propagation of light that astronomers and astrophysicists must account for. The point of course is that they (not me) do take these effects into account and correct for them." "In a way this work is very heroic but unheralded," adds Susskind, "An immense amount of extremely brilliant analysis has gone into the detailed corrections that are needed to eliminate these 'spurious' effects so that people like me can just say 'light travels with the speed of light.' So, there you have it. My concern about cosmic swimming pools and bent sticks does indeed apply, but physicists have taken the deviations into account so that other physicists, such as Susskind, who once proved Stephen Hawking wrong, can battle their way to a better understanding of the universe."
