Can Light Create a Time Machine?

In summary, Ronald Mallett is a physicist who is researching the gravitational field of circulating light beams, specifically the weak and strong gravitational fields produced by a single continuously circulating unidirectional beam of light. He has found new exact solutions for the Einstein field equations for the exterior and interior gravitational fields of a circulating cylinder of light and believes this could potentially lead to the creation of a time machine. However, there are still many challenges to overcome and it is currently not possible to travel back in time using this method.

That's the paper I already have. Unfortunately, it's not the right one -that's the Physics Letter A paper, not the Foundations of Physics paper where the CTC results are presented. The paper I'm looking for is:

R. L. Mallett, "The gravitational field of a circulating light beam," Foundations of Physics 33, 1307 (2003).

i have not seen any for free. one of the other websites i sent earlier has malletts email address maybe he could sent you a copy if you ask.
