New Scientist SPACE – Breaking News – Gravity theory dispenses with dark matter
The work appears to rule out the need to invoke dark matter or another alternative gravity theory called MOND (Modified Newtonian Dynamics). But other experts caution it has yet to pass the most crucial test – how to account for the afterglow of the big bang.
For now, I am still going to stick with the dark matter theory, such as Sean Carroll says; “Nobody would be happier than me if it turned out to be modified gravity rather than dark matter, but it’s becoming harder and harder to go along with that possibility.”
