As I view the spectacular picture of the Globular Cluster M13, I imagine that the sight from a hypothetical planet at its core must be like Times Square on a busy night.
But a few quick calculations on the back of an envelope have convinced me otherwise. It turns out that the average distance between stars at the core of M13 is about equal to 100 times the distance between the Sun and Pluto. Now thats a whole lot closer than is Alpha Centauri from us, but it's still a long ways.
Even inside something like M13, space is mostly enpty (well, aside from Dark Matter, that is).
