The Takeaway
For decades, 'Dark Matter' has been the invisible explanation for why galaxies don't fly apart, but this research suggests the problem is actually that gravity itself changes at low accelerations. The author found that this deviation from Newton's laws happens identically in everything from small-scale lab tests on Earth to pairs of stars and massive galaxies, suggesting a new universal law rather than a new type of matter.
From the abstract
Modifications to Newtonian dynamics at low accelerations have long been proposed as an alternative to dark matter to explain galaxy rotation curves. More recently, similar corrections have been invoked to interpret anomalies in Cavendish-type laboratory experiments and in the dynamics of wide binary stars, although the latter remain affected by ongoing observational debate. We show that, if deviations from Newtonian gravity occur in the low-acceleration regime, the available data are broadly con
