- Newer Maps seem to say Yes.
- Oscreen dialog seems to suggest No.
New maps always want to put Earth on the Alpha and Beta Quadrant border. But nothing in the onscreen dialog (the king of canon) bears this out. Most onscreen dialog seems to suggest that Earth is in the middle of the Alpha Quadrant.
And map people, if Sol is directly on the border, does that mean that Earth rotates into the Beta Quadrant 50% of the time?
