It's a matter of interpreting the data, and who gets the data first.When redshifts of Type Ia supernovae were found to increase non-linearly, it was hailed as evidence that the Universe was accelerating. This would violate most laws of gravity, not to mention the First Law of Thermodynamics on energy conservation. To explain the "accelerating" data, scientists claimed a repulsive "dark energy." The first reports from the Wilkinson Microwave Anisotropy Probe were interpreted to favour DE, though WMAP says nothing about acceleration. To quote Roger Penrose: "In my opinion, we must be exceedingly cautious about claims of this kind--even if seemingly supported by high-quality experimental results. These are frequently analysed from the perspective of some fashionable theory."Doubts about the "standard" cosmology and its dark epicycles continue to spread. From Space.com:Dark Energy and Dark Matter Might Not Exist, Scientists Allege "Ever since these concepts were first proposed, some astronomers have worked feverishly to figure out what each thing is, while other astronomers have tried to prove they don't exist, in hopes of restoring the universe to the more understandable place many would like it to be."A new look at the data ...
