Dark energy is an idiocy that does not work so Einsteinians are looking for an even greater idiocy: http://www.newscientist.com/article/mg20627643.500-did-a-sleeper-field-awake-to-expand-the-universe.html New Scientist: "In the late 1990s, observations of supernovae revealed that the universe has started expanding faster and faster over the past few billion years. Einstein's equations of general relativity provide a mechanism for this phenomenon, in the form of the cosmological constant, also known as the inherent "dark energy" of space-time. If this constant has a small positive value, then it causes space-time to expand at an ever-increasing rate. However, theoretical calculations of the constant and the observed value are out of whack by about 120 orders of magnitude. To overcome this daunting discrepancy, physicists have resorted to other explanations for the recent cosmic acceleration. One explanation is the idea that space-time is suffused with a field called quintessence. This field is scalar, meaning that at any given point in space-time it has a value, but no direction. Einstein's equations show that in the presence of a scalar field that changes very slowly, space-time will expand at an ever-increasing rate." Pentcho Valev wrote: http://cosmologystatement.org/ An Open Letter to the Scientific Community (Published in New Scientist, May 22, 2004) "The big bang today relies on a growing number of hypothetical entities, things that we have never observed-- inflation, dark matter and dark energy are the most prominent examples. Without them, there would be a fatal contradiction between the observations made by astronomers and the predictions of the big bang theory. In no other field of physics would this continual recourse to new hypothetical objects be accepted as a way of bridging the gap between theory and observation. It would, at the least, raise serious questions about the validity of the underlying theory." Why are all those rebels silent now? Perhaps, like Mr. Praline, they have realized that proving that dead science is dead is just as silly as proving that dead science is alive: http://www.youtube.com/watch?v=4vuW6tQ0218 Owner: Oh yes, the, uh, the Norwegian Blue...What's,uh...What's wrong with it? Mr. Praline: I'll tell you what's wrong with it, my lad. 'E's dead, that's what's wrong with it! Owner: No, no, 'e's uh,...he's resting. Mr. Praline: Look, matey, I know a dead parrot when I see one, and I'm looking at one right now. Owner: No no he's not dead, he's, he's restin'! Remarkable bird, the Norwegian Blue, idn'it, ay? Beautiful plumage! ........................ Mr. Praline: No, I'm sorry! I'm not prepared to pursue my line of inquiry any longer as I think this is getting too silly! University of North Carolina at Chapel Hill Professor David A. Plaisted is going to stop tweaking the Big Bang Model but is still being misled by red herrings (if there is A DECREASE IN THE SPEED OF LIGHT, the question of whether it occurs "through discrete levels" is a red herring): http://www.cs.unc.edu/~plaisted/ce/redshift.html David A. Plaisted: "The fact that red shifts appear to be quantized has interesting implications for the study of the universe. This suggests that the red shift may be caused by something other than the expansion of the universe, at least in part. This could be a loss of energy of light rays as they travel, or A DECREASE IN THE SPEED OF LIGHT through discrete levels. Maybe there is some other explanation." http://www.physorg.com/news4999.html "The widely accepted idea that the universe began with a Big Bang could be wrong, according to astrophysicists who took part in a "Crisis in cosmology" meeting in Portugal and reported in this month's Physics World magazine. According to the standard Big Bang theory, the universe began in a hot dense fireball about 13 billion years ago and has been expanding ever since. But despite plenty of evidence to support the theory, not everyone is convinced. Eric Lerner of Lawrenceville Plasma Physics, who organized the Portuguese meeting, says that certain properties of the cosmic microwave background - the so-called "echo of the Big Bang" - do not match predictions from the theory. Others are unhappy that cosmologists have had to introduce weird concepts like dark matter and dark energy to explain the universe. Mainstream scientists, however, have hit back, saying that we just need to tweak the Big Bang model and tie up "loose ends"." Mainstream scientists are going to tweak the Big Bang model forever because this brings billions: http://www.physorg.com/news179508040.html "More than a dozen ground-based Dark Energy projects are proposed or under way, and at least four space-based missions, each of the order of a billion dollars, are at the design concept stage." Billions also force mainstream scientists to ignore and eventually suppress any alternative idea, although in moments of aberration they admit: "We have a complete inventory of the universe," Sean Carroll, a California Institute of Technology cosmologist, has said, "and it makes no sense." http://www.sciscoop.com/2008/10 "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." http://www.springerlink.com/content/w6777w07xn737590/fulltext.pdf Astrophys Space Sci (2009) 323: 205211 Misconceptions about the Hubble recession law Wilfred H. Sorrell "The question is this: Do astronomical observations necessarily support the idea of an expanding universe? Almost all cosmologists believe as sacrosanct that the Hubble recession law was directly inferred from astronomical observations. As this belief might be ill- founded... (...) It turns out that the Hubble recession law was not directly inferred from astronomical observations. The Hubble recession law was directly inferred from the ad hoc assumption that the observed spectroscopic redshifts of distant galaxies may be interpreted as ordinary Doppler shifts. 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. (...) 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." http://www.time.com/time/magazine/article/0,9171,757145,00.html Monday, Dec. 14, 1936: "Other causes for the redshift were suggested, such as cosmic dust or a change in the nature of light over great stretches of space. Two years ago Dr. Hubble admitted that the expanding universe might be an illusion, but implied that this was a cautious and colorless view. Last week it was apparent that he had shifted his position even further away from a literal interpretation of the redshift, that he now regards the expanding universe as more improbable than a non-expanding one." http://www.nytimes.com/2010/01/26/science/26essay.html "The worrying continued. Lawrence Krauss, a cosmologist from Arizona State, said that most theories were wrong. "We get the notions they are right because we keep talking about them," he said. Not only are most theories wrong, he said, but most data are also wrong..." http://www.telegraph.co.uk/science/6057362/Give-scientists-the-freedom-to-be-wrong.html Martin Rees: "Over the past week, two stories in the press have suggested that scientists have been very wrong about some very big issues. First, a new paper seemed to suggest that dark energy the mysterious force that makes up three quarters of the universe, and is pushing the galaxies further apart might not even exist." http://www.smithsonianmag.com/science-nature/87150187.html "Dark Energy: The Biggest Mystery in the Universe (...)
