The paper states:
"First of all, the gravitational anomaly in the dynamics of binary stars cannot be attributed to dark matter because the required amount is absurd, and thus there is no way to save the standard theory of gravity."
- naasking 3y agoWhich applies to classical dark matter theories, not ones that naturally reproduce MOND dynamics.
- MattPalmer1086 3y agoI could easily be mistaken here, but wouldn't applying any dark matter theory to a binary system require it to have its own dark matter halo and core? I can understand how things like superfluid DM might help explain galactic rotations, but I'm having a harder time applying it to things like wide binaries.
- MattPalmer1086 3y agoOn further reading, I am fairly confident you are wrong. No dark matter theory can explain wide binary gravitational anomalies.
- naasking 3y agoI guess we'll just have to wait and see. Many of the superfluid dark matter proposals have already been ruled out by other observations anyway.
- MattPalmer1086 3y agoWe will indeed! I had heard superfluid DM had been ruled out for some things too. Exciting times!
