Is Dark Matter's Main Rival Theory Dead?
"One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up," write two U.K. researchers in the Conversation: Galaxies rotate much faster than predicted by applying Newton's law of gravity to their visible matter, despite those laws working well everywh...
Due to a quirk of Mond, the gravity from the rest of our galaxy should cause Saturn's orbit to deviate from the Newtonian expectation in a subtle way. Results from yet another team show that Mond also fails to explain small bodies in the distant outer Solar System... "Ultimately though, Mond, as presently formulated, cannot be considered a viable alternative to dark matter any more," the researchers conclude.
