^Yes, but my point is, if it's that easy to get to the edge, why hadn't others done it in the interim? Politics can't explain it, because it's not just one planet. Why hadn't the Vulcans or Andorians gone there?
It's just kind of a shoddy concept. I mean, why did they want to go past the edge of the galaxy anyway? What's out there aside from some globular clusters that would take a long time to reach? Not to mention that the galactic disk doesn't really have a definable edge anyway.
