The Dangers of the Modified Gravity Community
Theory of modified Newtonian dynamics has been incredibly predictive on a huge range of scales ranging from the entire universe down to tiny galaxies. But there are many observations that modify gravity really struggles with, as well as some observations that it makes some sense of. There are many feedback relationships where a galaxy if it has too many stars, for example, then it's going to start having lots of supernovae That means it's not going to form as many stars in the future. So I think the answer lies in those feedback relationships but it would be fair to say that they're not fully understood at this point in time.
