 , isn't it? If anything, allowing FTL just makes things more complicated, because you have to resolve stuff like time travel paradoxes, and explain how you have FTL, relativity, and causality in the same universe.

No, it isn't really. No explanation is required. You can certainly choose to.

But it's the matter of utterest simplicity to simply keep a hard scifi, and utterly ignore all the implications of FTL travel.

The simplest being, we were wrong. FTL has no effect on time whatsoever.

OF course this is also most simply achieved if the FTL isn't "literally" faster than light, instead going for the Alcubierre drive.

[QUOTE]Objects cannot accelerate to the speed of light within normal spacetime; instead, the Alcubierre drive shifts space around an object so that the object would arrive at its destination faster than light would in normal space.[1] Although the metric proposed by Alcubierre is mathematically valid in that it is consistent with the Einstein field equations, it may not be physically meaningful or indicate that such a drive could be constructed. The proposed mechanism of the Alcubierre drive implies a negative energy density and therefore requires exotic matter, so if exotic matter with the correct properties does not exist then it could not be constructed. However, at the close of his original paper[2] Alcubierre argued (following an argument developed by physicists analyzing traversable wormholes[3][4]) that the Casimir vacuum between parallel plates could fulfill the negative-energy requirement for the Alcubierre drive. Another possible issue is that although the Alcubierre metric is consistent with general relativity, general relativity does not incorporate quantum mechanics, and some physicists have presented arguments to suggest that a theory of quantum gravity which merged the two theories would eliminate those solutions in general relativity which allow for backwards time travel (see the chronology protection conjecture), of which the Alcubierre drive is one.[/QUOTE]

Which is becoming more and more appraised as theoretically possible. To the point that NASA is re-examining it BUT

I personally think NASA "re-examining the warp drive" as a dash-grab for its dwindling funding.
