TL;DR

This paper explores the theoretical possibility of creating closed timelike curves using rotating superconductors, but concludes that current technology makes practical implementation impossible.

Contribution

It derives the spacetime metric around a rotating superconductor and demonstrates the theoretical feasibility of generating closed timelike curves.

Findings

Closed timelike curves can be theoretically generated with rotating superconductors.

Practical implementation of CTCs with current technology is impossible.

The study connects gravitomagnetic effects in superconductors to general relativity concepts.

Abstract

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 SCRs. The possibility to use these CTC's to travel in time as initially idealized by G\"{o}del is investigated. It is shown however, that from a technology and experimental point of view these ideas are impossible to implement in the present context.
