From: http://vsevcosmos.livejournal.com/22610491.html Generation of Closed Timelike Curves with Rotating Superconductors. [gr-qc/0609117 UPDATED] The spacetime metric around a rotating SuperConductive Ring (SCR) is deduced from the gravitomagnetic London moment in rotating superconductors. It is shown that theoretically it is possible to generate Closed Timelike Curves (CTC) with rotating
