I think its fair to no longer call dark matter a fudge factor. The bullet cluster observations put a nail in that coffin. https://en.wikipedia.org/wiki/Bullet_

- yorwba 9y agoIt's a fudge factor in that the distribution of dark matter is fit to explain any deviations from our predictions about the effects of gravity. Even if we were subtly wrong about how gravity works, we could probably find some dark matter distribution that matches our observations. So long as we are unable to independently observe dark matter, we can't be sure how much of it is actually caused by some different phenomenon.
