Was also a major plot point in one of my favorite Star Trek TNG episodes, where Scotty and Geordi have to figure out a way to escape a Dyson sphere: <a href="http://en.wikipedia.org/wiki/Relics_(Star_Trek:_The_Next_Generation)" rel="nofollow">http://en.wikipedia.org/wiki/Relics_(Star_Trek:_The_Next_Gen...</a><p>One neat small thing in the episode is that a Dyson sphere is such a massive, almost incomprehensibly large and complex creation that even the people of Star Trek's 24th century were in awe of whatever civilization created it.
