Inhomogeneous cosmology in the cosmic rest frame without dark stuff
Günter Scharf
We study Einstein's equations with an isotropic but inhomogeneous metric in the cosmic rest frame. The equations are solved perturbatively in the late Universe. The leading plus ne…

Nonstandard cosmology
Günter Scharf
Considering radial geodesics in the Robertson-Walker metric leads us to abandon the co-moving coordinates. Instead we work in the cosmic rest frame. Since then the matter is in mot…

Nonstandard general relativity III: The Kerr class
Günter Scharf
We revisit the Kerr metric in Boyer-Lindquist coordinates and construct the corresponding class of nonstandard solutions of Einstein's equations. These solutions can be used to des…
