The
sector of space inside which the
insignificant blue sphere we call home is located, according to
Douglas Adams'
The Hitchhiker's Guide to the Galaxy series.
It's never really explained whether this sector includes the entire
solar system or just the
third rock from the sun.
It's probably also worth noting that any lifeforms originating from the Plural Sectors, like me and probably you, should not attempt
hyperspace travel as they're prone to experiencing inter-dimensional
foul-ups - something
Arthur Dent is all too familiar with.
