New Theory Challenges Need For Dark Matter 302
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)."

I'm sorry, but "gravitational effects" won't sell popsci books. For the sake of our royalties, let's stick to dark matter.

Yes, I agree. Dark gravity deniers should be kicked out of their profession. Once a consensus is reached, it is recognized as FACT!

Maybe, with chronically insufficient funding, researchers work better. It'll be known as the Paradox Berlusconii.

Hmmm... your espresso theory might explain some of the software made in the Seattle area in more recent years.

Well, THIS religious nutbar subscribes to the theory that gravity is really just the love felt between particles: just as absence makes the heart grow fonder, distance increases this attractive force, resulting in increased orbital velocities of stars.
Love makes the galaxy go 'round.

A religious rant, condemning other theories as inadequate, antiquated, and conforming to orthodoxy. On the internet too. Wow, who would have anticipated that?

Yeah. That's implausible. After carving up the turkey recently, the last thing left was the dark matter. Everyone seems to like the white matter better.

Indeed, stupid scientists made a big complicated theory about forces proportional to masses and then after doing experiments and finding that things fall the same regardless of mass, they cover up their error by adding even more factors!
Occam's Razor requires us to believe that stuff all falls at the same rate because God decided that was the best rate.
Why this rate? When God created the world, He made the rate of fall exactly enough that we could walk on two legs, while all Lower creatures cannot because the Falling Speed is not tuned for them. If Falling was even slightly slower or faster, your feet would hit the ground out-of-step and would not be able to walk - co-incidence? No, proof that God made the world for Man.

Don't forget - they also have geologists on trial for failing to predict the earthquake a few years ago. The Universe is merely seeking equilibrium.
