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.
The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world’s surface fresh water by volume.
What I find interesting about this is that this transition also happened in highly unrelated languages such as Hungarian, Greek and Swedish, not only in related Portuguese and French.
In Hungarian, /ʎ/ in most dialects turned into /j/, but the spelling ⟨ly⟩ was preserved, hence lyuk [juk].
In Swedish, /lj/ turned into /j/ in word-initial positions, but the spelling ⟨lj⟩ was preserved, hence ljus [ˈjʉːs].
In Cypriot Greek, /lj/ is often pronounced as [ʝː], especially by younger speakers. In Standard Modern Greek, it always surfaces as [ʎ].
I guess people find it hard to pronounce /ʎ/ but are too inert to change the spelling.
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.
