'Less Clumpy' Universe May Suggest Existence of Mysterious Forces

One of the most precise surveys of the structure of the universe has suggested it is "less clumpy" than expected, in findings that could indicate the existence of mysterious forces at work. From a report: The observations by the Dark Energy Survey and the South Pole Telescope chart the distribution of matter with the aim of understanding the competing forces that shaped the evolution of the universe and govern its ultimate fate. The extraordinarily detailed analysis adds to a body of evidence that suggests there may be a crucial component missing from the so-called standard model of physics. "It seems like there is slightly less [clumpiness] in the current universe than we would predict assuming our standard cosmological model anchored to the early universe," said Eric Baxter, an astrophysicist at the University of Hawaii and co-author of the study. The results did not pass the statistical threshold that scientists consider to be ironclad enough to claim a discovery, but they do come after similar findings from previous surveys that hint a crack could be opening up between theoretical predictions and what is actually going on in the universe. "If the finding stands up it's very exciting," said Dr Chihway Chang, an astrophysicist at the University of Chicago and a lead author. "The whole point of physics is to test models and break them. The best scenario is it helps us understand more about the nature of dark matter and dark energy."
