(10,857 posts)I think that's why the aliens aren't threatening to destroy London every week, because overcoming the curvature of space is not nearly as easy as travel between an infinity of similar universes, some of them different only in the point in time from which they originated, and therefore offering a paradox-free option to use a simulacrum of time travel.
When confronted with the choice between infinite versions of the tiny spaces within easy reach, or a dangerous, plodding, decades-or-centuries long journey between stars, most advanced civilizations will probably stick to their own front yards.
Of course, I know very little about any of those things, so it's easy for me to imagine without the shackles of limiting mathematics and physics!
(Oh, by the way, I mastered FTL a couple of months ago. One of the funnest games I've ever played.)
