> Isn’t there loads of evidence for dark matter including direct evidence like gravitational lensing? There is an equivalent boatload of evidence for modified gravity that can't be explained by particle dark matter [1], but one set of observations is hand waved away as a minor inconvenience while the other set is taken as definitive proof. If gravity doesn't work the way we expect, then lensing in galaxy collisions isn't necessarily telling us what we think it is. But setting that aside, if we take even the most naive modified gravity, MOND, then lensing does require a form of particle dark…

From a bit of armchair research this Friday, here are some articles on the connection between MOND and the Hubble constant: https://en.wikipedia.org/wiki/MOND https://arxiv.org/abs/1204.6359 https://arxiv.org/abs/1703.06110 http://file.scirp.org/Html/1-4500356_51478.htm https://ned.ipac.caltech.edu/level5/Sept01/Milgrom2/Milgrom3... https://academic.oup.com/mnras/article/438/2/1805/1016908 Basically what these are saying is that if the universe (and space around galaxies) is expanding, then stars would be dragged along with that expansion and move outward from the center of mass if they…
