From SR to GR in an easy math (and physical) way

    From SR to GR in an "easy" math (and physical) way

    Hello..i know that for example to go from Newtonian to SR you take:

    [tex] \frac{du}{ds}=0 \rightarrow \nabla _{u} u=0 [/tex]

    My question is ¿is there an "easy" form to go from SR to GR in the form:

    [tex] \nabla _{u} u=0 \rightarrow \nabla R_{ab} =0 [/tex]
    Or to get Einstein equation appart from using the Lagrangian formalism... using "Differential Geomertry" or similar...:confused: :confused:

    Your first claim doesn't make much sense to me. Can you clarify?
    Are you trying to describe the evolution of the universe as a geodesic in some abstract space?
