Multiple results point to Modified Newtonian Gravity

Science

Study of wide binary stars reveals new evidence for modified gravity at low acceleration:

Chae concludes, “At least three independent quantitative analyses by two independent groups reveal essentially the same gravitational anomaly. The gravitational anomaly is real, and a new scientific paradigm shift is on its way.”

The observed gravitational anomaly is remarkably well consistent with the MOND-type (Milgromian) gravity phenomenology. However, underlying theoretical possibilities encompassing the MOND-type gravity phenomenology are open at present, and this may be welcome news to theoretical physicists and mathematicians.

This is a big deal – assuming there isn’t something fundamentally wrong with how the multiple data sets are being analyzed by the researchers. It would mean that rather than keep on searching for dark matter, the gravitational anomalies being observed can be explained, not by some sort of deus-ex-machina, but by modifying our description of how gravity works in certain conditions.

It’s a simpler answer than invoking something that can describe the observations well but requires all sorts of hand-waving to invoke. Sort of like cosmic inflation or epicycles…

And it would mean that there’s a lot of physics that needs to be uncovered. Fun!

    Just a note to say I am enjoying your posts now that you have consolidated to one formate. Some interesting perspectives as well as some real brain teasers,

    • Thanks John. I have a few more things I want to try out and then I think I’ll be able to settle into a routine.

      And I need to get a better work flow for the video.
