Are there MOND theories that attempt to account for dark energy too? Or only dark matter?

- mr_mitm 4y agoNot that I'm aware, but there are modified GR theories. In classical GR, the equations can be derived by applying the principle of least action with the Ricci scalar R being the Langrangian. People are studying what happens if you assume the Lagrangian is a function of R, like R^n or so. It doesn't have the same stigma as MoND, but it's also not that popular. It's also very hard to test for. https://en.wikipedia.org/wiki/F(R)_gravity https://en.wikipedia.org/wiki/F(R)_gravity
