>We know for a fact that gravity is _not_ Newtonian, that the inverse square law does not hold
[citation needed]
The consensus is that gravity - outside of extreme mass/energy environments - works just as Newton described it to many many decimal places.
Emphasized part added because people in the replies thought that I literally think that General Relativity is somehow wrong. Don't be dense. All I'm saying is that gravity at galactic scales works as Newton described it. General Relativity has extremely tiny effect at those scales.
