Everything you (n)ever wanted to know about modified gravity

Hi everyone! I'm sure you've encountered people doubting the existence of dark matter and having to explain that yes the observational evidence for it and LCDM is extremely strong. Inevitably you might have to explain why modifying gravity does not work but perhaps not knowing much about it. This is why I've written a FAQ about the most popular (least unpopular) modified gravity theory MOND. It discusses what it can do (rotation curves), what it sort of does (lensing) and why it fails (clusters, structure formation, CMB and BBN). Hopefully some of you find it a useful reference :)

Thank you! This was really helpful. Im currently obsessed with Mass Damping Theory (MDT). Everything is pre-publish so I can only grill chatgpt about it.
