ST:TNG:06 - "Where No One Has Gone Before" (Stardate: 41263.1) - this is another episode which bears homage to an Original Series episode - in this case in the title (the 3rd episode of the first season "Where No Man Has Gone Before"). This is also the episode that introduces The Traveler (played by Eric Menyuk) as a traveler that combines the futuristic concept (even for the 24th century) of space, time, and thought to get around the universe. Indeed, the Enterprise, though the Traveler's help, gets stuck at the edge of the universe with only him to get them back! A very interesting concept for an episode - I think they can surely expand on this concept for a feature film. The Traveler also makes a comeback in a future TNG episode (though not until the very end of the 7th season).
