I think OP means that LMS isn't a place per-se (like a planet, or maybe even a solar system is a "place"). It's a whole bunch a places bound together by gravity.
A solar system is a whole bunch of places bound together by gravity, too. What's the fundamental distinction here? That the center of mass isn't approximately one massive thing (e.g. the solar system is 99% the center -- the sun)?
In a very shallow, simplistic sense, we see all these other amazing phenomena out there. Our home seems like a little rural backwater, crossroads and a store kind of thing, by comparison.
