[sparky_]

True, although the Fermi Paradox still sort of applies here, e.g., even if the galaxy were teeming with aliens zipping all over the galaxy in their warp-capable spacecraft, the odds of them charting a course right past our fairly uninteresting solar system seem low.

This is likely not helped by the fact that we are more than halfway out to the edge of the galaxy, in one of the Milky Way's spiral arms; since we're not near the galactic centre, there are less possible travel paths that pass by us (if we just assume arbitrary random travel between any two points.)

So even if it is happening right now in abundance, and even if we can detect its occurrence, are any of those paths close enough to us to be detected?
