So I was lying in bed this moring(summer break, yaaaay) when it suddenly occurred to me that most causality paradoxes are caused by the exchange of information, so if when moving FTL no information could be exchanged in or out, preventing any sort of causality paradox, then it further extended to stars to prevent that right, no information in or out of a star system of any construct or natural formation, large one floating in space. I should clarify that when I say cloaked I mean no information can enter or leave the area involved, whether that be a cluster of spaceships moving together, or a little pocket universe contained within a brown dwarf.
Let's say that all FTL spaceships and star systems are cloaked in an area. No FTL travel is allowed within the borders of the said constructs, or natural formations, presumably various solar systems.
Further let's say that FTL travel is confined to routes that cant form closed loops, and so can't lead to time travel.
Does this successfully prevent all Potential FTL paradoxes that could occur, most or none or just an indeterminable portion?
Note:This sprung from thoughts on routes taken, FTL routes in which causality paradoxes couldn't occur presuming the spaceships involved followed all of the constraints involved in the routes. Note:This is also a potential solution for dark matter, right? Note:This was something that @Willk pointed out, to a degree, assume that any faster than light spaceships are actively trying to avoid causality paradoxes
