This is very cool. Samuel Arbesman created the "Milky Way Transit Authority" as a schematic representation of the relationship of major points in our galaxy.
We, of course, are way, WAY out in the suburbs, circling that little "Sol." Imagine for a moment the immense congestion (?and traffic) at the galactic center.
Then consider that the Milky Way galaxy is one of approximately 100,000,000,000 in the known universe. Absolutely humbling.
