Re: Did TNG's Early Scope Shrink?
I don't think so. The episode Where No One Has Gone Before
stated only eleven percent of the Milky Way galaxy had been explored. It would seem odd for Starfleet to use resources to explore other galaxies when they were nowhere close to having completely explored their own. In my opinion.
