In his Space.com article: "Scientists Say Dark Matter Doesn't Exist", author Ker Than writes:

"Now John Moffat, an astronomer at the University of Waterloo in Canada, and Joel Brownstein, his graduate student, say those announcements were premature.

In a study detailed in the Nov. 21 issue of the Monthly Notices of the Royal Astronomical Society, the pair says their Modified Gravity (MOG) theory can explain the Bullet Cluster observation. MOG differs from other modified gravity theories in its details, but is similar in that it predict that the force of gravity changes with distance.

"MOG gravity is stronger if you go out from the center of the galaxy than it is in Newtonian gravity," Moffat explained. "The stronger gravity mimics what dark matter does. With dark matter, you take Einstein and Newtonian gravity and you shovel in more dark matter. If there's more matter, you get more gravity. Whereas for me, I say dark matter doesn't exist. It's the gravity that's changed."

Using images of the Bullet Cluster made by the Hubble, Chandra X-ray and Spitzer space telescopes and the Magellan telescope in Chile, the scientists analyzed the way the cluster's gravity bent light from a background galaxy—an effect known as gravity lensing. The pair concluded that dark matter was not necessary to explain the results."

Here are two scientists that agree that gravity gets stronger as you go out from the center of the galaxy. Modified Gravity theory (MOG gravity).

As I wrote in my article - Dark Matter, Who Needs it? I say, "The reason the stars' gravity gets stronger is - in a rotating spiral galaxy, the galaxy's outlying stars are traveling faster then its central stars, and are therefore at a higher energy level relative to space ("space energy level"). Therefore the nucleons of the outlying stars', inertial mass will be greater then the central stars. Therefore, according to Newton's "Law of Gravity", their gravity will be stronger." - Newton's gravitation formula doesn't change, only the nucleon's "inertial mass" becomes stronger because they are at a higher "space energy level". ( Newton didn't know this happens because, particle accelerators wouldn't be invented for another couple of hundred years.)
