If you want to say it's a "parameter distribution" or something like that, that's fine. It doesn't change the fact that this thingie, whatever you want to call it, is already present in our existing theory of gravity, GR, and is already adjustable in that theory. So we're not adding anything new to the theory if we adjust this thingie to take into account observed motions for which we can't see the gravity source that causes the motion.
- throwawaymaths 4y agoDo you understand the concept of overfitting?
- pdonis 4y agoSee the response by DiogenesKynikos. The "fitting" is not being done the way you appear to think it is.
- throwawaymaths 4y agoI don't think you understand the concept of explanatory power. Because dark matter cannot be observed we must manually tune the dark matter distribution for each galaxy. This creates new parameters that don't exist in the theory that are necessary to properly explain phenomena. Whether or not they exist in the theory is irrelevant to the fact that they are necessary.
