I was wondering whether someone has been able to find an exact solution of the Einstein field equations for the gravitational field of a galaxy (in which the galaxy could be modeled as a spinning disk for instance). Such a solution would clearly not be spherically symmetrical, though cylindrical symmetry could be assumed (as an approximation). Any references ?(adsbygoogle = window.adsbygoogle || []).push({});
