A new modified gravity theory replaces dark matter with an "infrared scheme"
Spiral galaxies rotate at such a high speed that the gravity calculated only from their visible stars could not prevent them from dispersing. To solve this puzzle, physicists have postulated ...

Does dark matter actually exist? New theory says it could be gravity behaving strangely
"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." ...
Our solar system officially houses eight planets, but some scientists say there could be a ninth. And that’s not just Pluto aficionados – evidence suggests a huge undiscovered world lurks on the dark ...
One of the biggest cosmological mysteries centers on a discrepancy in how fast the universe is expanding. A new study comes to an intriguing solution by applying a modified theory of gravity and an ...
(via Sabine Hossenfelder) Most astrophysics are pretty convinced that 80% of the matter in the universe is some invisible stuff that they can’t detect - dark matter. The idea has become more popular ...
Wide binary stars as direct probes of the nature of gravity at low acceleration weaker than about 1 nanometer per second squared have been hotly debated. The nature of gravity at such low acceleration ...
An international group of scientists, including Case Western Reserve University Astronomy Chair Stacy McGaugh, has published research contending that a rival idea to the popular dark matter hypothesis ...
A theory developed to replace dark matter may mean bad news for Planet Nine, a hypothetical as-yet-unseen world in the outer solar system. The odd orbital alignments of icy objects in this region that ...

Scientists claim to hack gravity and now crush space & time itself
Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.
How did the first galaxies after the Big Bang form and evolve? Were they small and attributed to dark matter or were they large and some other force attributed to their growth? This is what a recent ...
