I take this to mean that if you could travel FTL to a very distant place that you could never get to otherwise, like say whatever universe there is that is farther away than light can travel in age of the universe, then there isn't a causality problem. Which isn't controversial. I'm pretty sure there are other FTL scenarios in which there is no paradox.
- blincoln 6y ago> In this particular post, she referenced causality in one sentence Yes, precisely. She made an extraordinary claim, as if it were a minor footnote, instead of "every mainstream description of relativity is wrong in this very fundamental way." If it were the only time I'd seen her do that in her writings, it wouldn't trouble me as much. It seems to be common, and that makes me concerned that e.g. she may be off in some branch of physics that's not well accepted at this time.
