cosmological spacetimes
Hi,
I need an example on how to perform the Einstein Field Equations for a universe which is anisotropic and where the clustering of masses are aligned to an arbitrary axis (axial pole).
Just like the example given for Friedmann equations in the sagemanifolds examples website.
Thanks
As stated this is a little broad. Do you have some equations for what you'd like to do, and are there any specific stumbling blocks you are having getting started? I understand more-or-less what you're asking, but most people on here aren't cosmologists so the question would be more meaningful if you posted some math and/or code.
