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?
I think they are large regions of space roughly categorized. This whole thing might be our local group? Idk what it is exactly.
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?
