I know where you went wrong.

You forgot to Gaussian smooth the random density field.



Go back, plug in and it will change your conclusions to a more satisfactory state.

You should also consider this.

Although the resulting Einstein equations can be solved in the usual spacetime discretization fashion, an interesting alternative method of solution is the symplectic operator splitting formulation [40, 121] founded on recognizing that the second order equations can be obtained from the variation of a Hamiltonian decomposed into kinetic and potential subhamiltonians,



There, I hope that simplifies the problem for you.

If you really want to understand Einstein, you have to study his explanation of radio. It is as follows, a verbatim transcript, I assure you.

You see - wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: You send signals here, and they receive them there. The only difference is that there is no cat.
