The Milky Way is often used as a model when estimating interstellar travel distances. For instance, if a trip is described as going from the "core" of a galaxy to the "rim" of the galaxy, the distance can be estimated to be a significant fraction of the 125,000 light-year radius of the Milky Way.

The Milky Way is the actual setting for Star Trek, making its features even more relevant to the debates involving Star Trek.
