"evidence for modified gravity at low acceleration from Gaia observations of wide binary stars." A potential replacement for dark matter scaling? Any physicists want to try to answer some questions? (phys.org)

My understanding is the researcher took Gaia probe information and looked at “wide binary stars” (not sure what defines wide, but there must be a ton of them), within 650 light years of earth. They found the ones that accelerate the least (relative to each other? Rotationally?) are, and this is where I get confused, moving...

Sean Carroll just did a long solo episode of his Mindscape podcast (preposterousuniverse.com) which includes a survey of the various research areas attempting to explain the dark matter.

It’s a long episode but it in he describes what to look for in modified gravity claims.

This is not to say the specific claims from this group are incorrect or lacking. I’d consider the podcast episode a tool to help you analyze and form an opinion on what is being said.
