Gas Rich Galaxies Confirm Prediction of Modified Gravity Theory

Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity known as MOND, according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. This the latest of several successful MOND predictions raises new questions about accuracy of the reigning cosmological model of the universe, writes McGaugh in a paper to be published in March in Physical Review Letters.

Why am I interesting for this article?
Modern cosmology says that: "for the universe to behave as it does, the mass-energy of the universe must be dominated by dark matter and dark energy. However, direct evidence for the existence of these invisible components remains lacking. An alternate, though unpopular, possibility is that the current theory of gravity does not suffice to describe the dynamics of cosmic systems."

What is my conttribution of this article?
My contribution is the dark matter is not like that everyone say it. Before, the astronomy thought that dark matter can destroy galaxy, but now, the dark matter is used to support a galaxy.
In my conclution, never say something that you don´t know. Always read and search information about the and then you can say something that you learned.
