Galaxy rotation measurements lean toward modified gravity

Modified gravity under an estimated mean external field correctly predicts the observed statistical relation of accelerations from both the inner and outer parts of RCs.

Unique Prediction Of Modified Gravity Challenges Dark Matter

Unique Prediction Of Modified Gravity Challenges Dark Matter Press Release - Source: CASE WESTERN RESERVE UNIVERSITY Posted The best example is represented by the Sunflower galaxy (NGC 5055) with the strongest external field among SPARC galaxies, whose well-measured rotation curve shows a mildly declining behavior at large radial distance and can be accurately modeled only with an external field effect. CREDIT Creative Commons 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 more accurately predicts a galactic phenomenon that appears to defy the classic rules of gravity.
