+ - Survey finds no hint of dark matter near Solar System--no hint of a clue, either->

Submitted by Eponymous Hero
Eponymous Hero writes: Does dark matter exist or doesn't it? It seems these results don't shed as much light as we'd hoped.

"Moni Bidin says he’s not sure whether dark matter exists or not. But he says that his team’s survey is the most comprehensive of its type ever done, and the puzzling results must be reckoned with. 'We don’t have a good comprehension of what is going on,' he says."

This has the smell of a Neutrinogate scandal, but at least we've been warned about the shoulder shrugging.

"As an example, Newberg notes that the researchers assumed that the group of stars they examined were smoothly distributed above and below the plane of the Milky Way. But if the distribution turns out to be lumpier, as is the case for stars in the outer parts of the galaxy, then the resulting calculations of dark matter density could be incorrect.

Flynn agrees that there are a number of ways that the method employed by Moni Bidin and his co-authors 'could get it wrong.'"
