Wide binaries offer a means to test Modified Newtonian Dynamics (MOND), an alternative explanation for galactic rotation curves compared to dark matter. Various analyses of wide binary systems using Gaia DR3 data are in conflict, with some favoring MOND and others favoring General Relativity (GR). Will future analyses using Gaia DR4 data align more consistently with MOND than with GR?
This question resolves as YES if all the most methodically robust analyses of wide binaries, using Gaia DR4 data, exhibit discrepancies with GR that are in line with MOND.
This question resolves as NO if the analyses of wide binaries using Gaia DR4 data are aligned with GR, or if most of the methodically robust analyses do not agree on whether the Gaia DR4 data is consistent with GR.
Determining the resolution of this question necessitates a judgment regarding the methodical robustness of different analyses. I intend to consider informed discussions in the comments while ultimately reserving final judgment.
