Galaxy dynamics are confronted with one of the deepest problems of modern physics: the dark matter problem. The motions of stars and gas observed exceed what can be explained by the mass visible in ...

Modified gravity theories: dwarf galaxies speak
The most discreet dwarf galaxies in our Universe reveal a gravitational anomaly that has intrigued astronomers for decades. While large spiral galaxies seem to follow well-established rules, the ...
Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...
Although dark matter is a central part of the standard cosmological model, it’s not without its issues. There continue to be nagging mysteries about the stuff, not the least of which is the fact that ...

We learn more about Modified Newtonian Dynamics aka MOND. What if there is no such thing as dark matter? What if our understanding of gravity is just wrong? New work is taking another shot at that ...
Galaxies in the early universe were merging up to 10 times more than is predicted by theories of modified Newtonian dynamics, known as MOND. This rate of mergers is instead in line with theories that ...
(via PBS Space Time) What if there is no such thing as dark matter? What if our understanding of gravity is just wrong? New work is taking another shot at that Einstein guy. Let’s see if we’ve finally ...
