I was under the impression ftl does not actually permit backwards time travel
Do you have more information on this? My understanding was that, from the perspective of relativity, traveling faster than light was actually identical to traveling backwards in time.
I’m on my phone and don’t have a link off the top of my head but tldr events can appear backwards in some reference frames but you yourself can’t actually go back and interact with your own past.
