Black Holes Not Affected by Dark Matter, Say Astrophysicists - Technology Review

Black Holes Not Affected by Dark Matter, Say Astrophysicists - Technology Review: "But in the fine tradition of science, this clears up one mystery only to reveal another. If dark matter has this powerful gravitational influence, why doesn't it form into black holes?

Nobody knows. But there is another group of astronomers who will be studying this result with interest. These guys think dark matter is an unnecessary invention. Instead, they say, the rotation of galaxies can be explained if the force of gravity is stronger over these galactic distances.

So according to them there is a simpler explanation for the absence of a link between dark matter and black holes: it's that dark matter doesn't exist."
