I had my suspicions but I wanted to see what others made of it. The headline was obviously dodgy, but that might just have been the reporting rather than the paper. And I glanced at the paper but didn’t dig through. Since then I had a slightly more careful poke through it, and sentences like this ring some pretty loud alarms:
The masses of electrons, muons, and tau can be explained by the different curvatures of universe, galaxy, and solar system, respectively.
Anyway, I appreciate your comments and the comments of the person you replied to. I should have recognized this for what it was.
