After reading the question Cloaking the USS Enterprise, I'm trying to remember an episode of TNG.

  • It seems to run 3 different timelines in parallel, Current-time past time and future time.
  • They all do some sort of scan at a specific spot in space, and this causes some kind of effect to happen backwards in time, threatening to prevent the formation of human life.
  • Q was involved.
  • There was a trial, about mankind's right to exist.

What brought it to mind was the Enterprise of the future, I think it had 3 warp nacelles... and maybe a cloak... but that's going to be a separate question once I get the episode :-)

  • Woah, Google is good: google.com/… I’m impressed. Commented Mar 26, 2012 at 9:44
  • fair enough, not my best question

That's "All Good Things", the series finale of Star Trek: The Next Generation.

The trial refers back to the series' pilot episode, "Encounter at Farpoint".
