The impression I had from reading Bell’s article, and from wading through Yourgrau’s disappointing book, was that Godel was saying that relativity permitted past directed time travel, via CTCs, but in a universe with CTCs time could not exist.

This struck me as being a bit unsatisfactory, and I wondered if others shared the same impression.
