Does dark matter really exist?

A recent story in Nature reports no signs of dark matter from the Large Underground Xenon (LUX) Detector, deep underground in South Dakota (photo below by Carlos Faham). Certainly not a death-knell for the theory (indeed, the experiment is ongoing) but, as a draft paper notes, “the LUX data are in strong disagreement with low-mass WIMP signal interpretations of the results from several recent direct detection experiments.”
