- I've been doing research lately on practical methods of time travel and I've lo
- cated an article by Frank J. Tipler titled "Rotating cylinders and the possibil
- ity of global causality violation", in Physical Review D from 1974. The article
- postulates that a large but finite cylinder rotating about twice a millisecond
- might generate Closed Timelike Lines. I've also found sources that say a millis
- econd pulsar rotating at the same speed might do the trick (John Gribbin). Any
- thoughts as to whether using such a pulsar to move backwards in time is relativ
- istically feasible, and what moving through a Closed Timelike Loop generated in
- this way would be like? Other technically possible methods of time travel woul
- d also be appreciated.
