New Theory Challenges Need For Dark Matter

New submitter elsurexiste writes "An Italian Physicist came up with a strange way to explain anomalous galactic rotations without dark matter, instead relying on the gravitational effects of faraway matter. The article explains, 'Conceptually the idea makes little sense. Positioning gravitationally significant mass outside of the orbit of stars might draw them out into wider orbits, but it’s difficult to see why this would add to their orbital velocity. Drawing an object into a wider orbit should result in it taking longer to orbit the galaxy since it will have more circumference to cover. What we generally see in spiral galaxies is that the outer stars orbit the galaxy within much the same time period as more inward stars. But although the proposed mechanism seems a little implausible, what is remarkable about Carati’s claim is that the math apparently deliver galactic rotation curves that closely fit the observed values of at least four known galaxies. Indeed, the math delivers an extraordinarily close fit.' As usual, these are extraordinary claims that divert from the consensus, so keep a healthy skepticism. The paper is available at the arXiv (PDF)."

Odd how the fanatical, radical athiests get away with trolling so easily, and sometimes get modded up. Athiesm takes as much of a leap of faith as belief in a diety or dieties. More if you've actually experienced a diety. It's sad how so many athiests think religion is anti-science, and how they somehow think that you can have science or religion but not both, when over half of scientists are in fact religious.

I wish everyone would stop the damned trolling. It annoys me and detracts from slashdot. This thread is no place for a religious discussion. And if they don't believe in a diety why do they even mention one?
