Re: How far has Starfleet explored
I remember on that special that Bob Picardo hosted just before the "Voyager" premiere, it was said that 7% of the galaxy had been explored around the time of TOS, and an additional 15% around TNG.
Not sure what their source for this was.
I think the quote from Wesley was that 19% of the galaxy was charted. Over a million stars have been observed and charted today...out of 200-400 billion stars. Kind of makes you feel small.
It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring. Carl Sagan
