New Preprint on Wide Binaries Supports MOND

[QUOTE="ohwilleke, post: 6876218, member: 19562"] [B]TL;DR Summary:[/B] Wide binary stars have weak enough gravitational fields to enter the MOND regime, and a paper looking at new better data on them supports this hypothesis. In a dark matter hypothesis, wide binary stars should exhibit no dark matter phenomena since dark matter halos are so much bigger than pairs of distant gravitationally bound pairs of stars. But, in a MOND hypothesis, wide binary stars should be more strongly bound to each other than Newtonian gravity would predict. GAIA's latest edition has greatly improved the quality of the data on wide binary star systems allowing these hypotheses to be compared to observations. A paper looking at new data sees a MOND effect in wide binary stars. The discussion engages with possible sources of noise or bias in the results that have been proposed in connection with earlier wide binary data, and finds those hypotheses to be implausible at best.

Hernandez, "Internal kinematics of [I]GAIA[/I] DR3 wide binaries: anomalous behaviour in the low acceleration regime" [URL='https://arxiv.org/abs/2304.07322']arXiv:2304.07322[/URL] (April 14, 2023).
