Where the hell are we?

In case you would like a little help visualizing where our Galaxy is, in relation to its surroundings, this might help (a response from ChatGPT to my question about it, in which I suggested the "edge of the city" metaphor):

The Milky Way is located on the outskirts of the Virgo Supercluster, which is a massive cluster of galaxies that acts as a central hub in this part of the universe.

The Virgo Supercluster itself is part of an even larger structure known as the Laniakea Supercluster, which encompasses over 100,000 galaxies stretched out over 520 million light-years. Within this vast structure, the Milky Way, along with its local group of galaxies, is situated toward the outer regions of the Laniakea Supercluster.

Beyond the edge of our galaxy and its immediate galactic neighborhood lies the Local Void, a vast, relatively empty region of space. This void serves as a stark contrast to the densely packed clusters of galaxies found in the supercluster. In this sense, describing our galaxy as being on the "edge of the city" with the void beyond is a useful visualization to capture our relative position in the cosmos.
