After an elementary introduction to the basics of Einstein’s theory of gravitation, we simply present the Gödel’s solution and the geodesic equations associated with it.
This equations are then explicitly solved obtaining its full set of temporal geodesics.
Armed with such explicit expressions, the geodesic time-travelling possibilities of Gödel’s universe are discussed.
We search for their time-like closed geodesics that, following ...
