Abstract: Based on general (1 + 3) threading of the spacetime (M, g), we obtain a new and simple splitting of both the Einstein field equations (EFE) and the conservation laws in (M, g). As an application, we obtain the splitting of EFE in an almost FLRW universe with energy‐momentum tensor of a perfect fluid. In particular, we state the perturbation Friedmann equations in an almost FLRW universe.
