Phys. Rev. D 9, 2203–2206 (1974)Rotating cylinders and the possibility of global causality violationReceived 6 November 1973; published in the issue dated 15 April 1974 In 1936 van Stockum solved the Einstein equations Gμν=-8πTμν for the gravitational field of a rapidly rotating infinite cylinder. It is shown that such a field violates causality, in the sense that it allows a closed timelike line to connect any two events in spacetime. This suggests that a finite rotating cylinder would also act as a time machine. © 1974 The American Physical Society URL:
