Smoking-gun evidence for modified gravity at low acceleration from Gaia observations of wide binary stars

A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary stars, usually referred to as wide binaries in astronomy and astrophysics.

@Wowbggr this seems potentially huge? Claims that it does away with the need for dark matter? Do you have any lay-accesible references to the dark matter impact?

It would seem so to me. I can't point you in any particular direction for that but as I recall (don't quote me!!) one of the implications from MOND was no dark matter required to make the maths for orbital mechanics work.
