New Paper on ‘MOND’ Argues That Gravity Adjustments At Very Low Accelerations – Slashdot

MOND — MOdified Newtonian Dynamics is a speculation that Newton’s legislation of gravity is wrong below some prerequisites. Now a paper claims {that a} find out about does certainly display that pairs of broadly separated binary stars do display a deviation from Newton’s 2d Regulation, arguing that, at very low ranges, gravity is more potent than the legislation predicts.
Phys.org writes that the find out about “reinforces the proof for changed gravity that used to be prior to now reported in 2023 from an research of the orbital motions of gravitationally certain, broadly separated (or long-period) binary stars, referred to as extensive binaries.”However RockDoctor (Slashdot reader #15,477) calls the speculation “very a lot disputed.”
YouTubing-astrophysicist Dr Becky thought to be this document a few months in the past (2023-Nov-09), below the name “HUGE blow for trade idea of gravity MOND”. On the very least, astrophysicists and cosmologists are deeply not sure whether or not this information helps or discourages MOND. (Shortened remark as a result of verification downside.)Final week, I up to date my annual rely of MOND and different “selection gravity” publications. Whilst analysis on MOND (and others) continues, and any “suppression” the tin-foil-hat brigade wish to scream about is useless, it stays an unpopular (not-equal-to “suppressed”) box. Typically, astronomical e-newsletter counts are expanding, and MOND sticks with that pattern. If anything else is rising in popularity, it is the “MOG” form of “MOdified Gravity”.
