How to Modify Gravity Without Deep Theory
Newtonian gravity is the limit though in the weak field of general relativity. So how would you go about changing gravity? How do you go about modifying gravity without any deep theoretical superstructure? Just the idea of how could gravity be modified? The easy thing to imagine doing and certainly something that was at the top of the minds of people who thought about rotation curves and things like that when they try to get rid of dark matter back in the day is that you change the inverse square law. All you are doing is changing the magnitude of the gravitational force from one over r squared to something else. And even if you do not have a deep seated quantum field theory justification for doing so you can
