# Correction to Newton's law of Gravity for dark energy

Is there any correction to Newtons law of Gravity that takes into account the expansion of the universe?

• Yes and No. It's modified is for dark non-baryonic matter and It's called MOND - Modified Newtonian Dynamics. See arxiv.org/abs/1404.7661. There's BIMOND theory which produces a parameter in the cosomological constant. – Cinaed Simson May 13 at 20:40
• @CinaedSimson that appears to be an answer – Kyle Kanos May 15 at 23:52

Long before you can address that you need to switch from Newton's description of gravity to Einstein's. General relativity includes the Einstein field equation $$R_{ab}-\frac{R-2\Lambda}{2}g_{ab}=\kappa T_{ab}$$. Dark energy is represented by $$\Lambda$$. It's difficult to relate this back to Newtonian physics because a point mass's gravity in an otherwise flat spacetime has $$R=0$$.
