Modifying gravity: Pavel Kroupa and colleagues have shown that Modified Newtonian Dynamics does a good job at describing the properties of open clusters of stars. (Courtesy: Volker Lannert/University ...

Dark matter is currently the most widely accepted hypothesis for explaining some of the weirdness we see in the cosmos – but it’s not the only possibility. Now, a team of astronomers has discovered ...

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 ...

Case Western Reserve astronomer Stacy McGaugh and international collaborators detect ‘external field effect,’ a prediction unique to rival dark matter hypothesis An international group of scientists, ...

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 ...

MOND, a modified law of gravity, correctly predicted in advance of observations the velocity dispersion -- the average speed of stars within a galaxy relative to each other -- in 10 dwarf satellite ...
