I think most of the galactic regions are made up names based on the following...
I asked the AI assistant Grok what the Hawking's Gap was and it gave me an answer as if Elite Dangerous was true life without actually referencing Elite Dangerous.
Then I ask if the info was only relevant to Elite Dangerous:
The information about Hawking's Gap I provided is indeed specific to the fictional universe of the video game Elite Dangerous...

In real life, there is no astronomical region in the Milky Way galaxy officially named "Hawking's Gap." The Milky Way, as we understand it through current science, is a barred spiral galaxy with a diameter of about 100,000–200,000 light-years, featuring a central bar, spiral arms (like Perseus, Scutum-Centaurus, and Sagittarius), and various star clusters, nebulae, and voids. While Stephen Hawking's name is honored in science (e.g., Hawking radiation related to black holes), no specific region of our galaxy bears his name as a "gap" or otherwise in official astronomical catalogs. Any "gaps" in the Milky Way, such as areas with lower star density or dust lanes, are not designated as "Hawking's Gap" in real-world astronomy.
So, to clarify: Hawking's Gap is a concept unique to Elite Dangerous and does not correspond to a real-life feature in the Milky Way.
