The radius of the currently observable universe is about 50 billion light-years and this map depicts a sphere with a radius of about 1 billion light-years, so if my calculamalations are correct, following through with sphere volume V being V=4/3πr³ this map depicts about 0.001 percent of the observable universe.
Wonder why opaque structures were chosen. The locations depicted are still almost 100% empty space, unless you’re counting the interstellar medium as an object.
Would you rather see a picture of almost 100%empty space?
Fascinating! Looked the names up on Wikipedia:
I thought this was a 3D image of a shattered pelvis.
tl;dr; Image source. More images and a YouTube video.
In case someone wanted the source of the image, it is an illustration included in a 2020 IRFU (Institute of Research into the Fundamental Laws of the Universe) article published on the CEA website describing the discovery of a “South Pole Wall” located in the direction of Earth’s south pole that had, until galaxy velocity data could be collected integrated, remained hidden.
The article was a preliminary publication before the main paper was published in The Astrophysical Journal (APJ) here. The paper contains several additional illustrations of the South Pole Wall; the article contains an interactive 3D visualizations, a video (with English and French narration), and a set of more high resolution images.

What are all those things then?
Can anybody shed some light into what repellers, walls and attractors are? Of course I understand repellers probably repel stuff, and attractors attract it. But like… what’s their deal?
