Oof, I have bad, or maybe good, news for you: this isn't the universe. This is just the local structure of galactic superclusters to us. Just a knot on one of the myriad galactic filaments. 1 Gly out of a 30 Tly (edit: that's not right, closer to 100 GLy) and growing known universe. It's real big, don't get me wrong, but compared to the whole kit and kaboodle it's a rounding error.
SEA has a great video on The Great Attractor (and our local supercluster complex) that I recommend.
For a bigger view, check out https://mapoftheuniverse.net/ , although necessarily this isn't presented geometrically the way the one you linked is.
The Wikipedia list of largest observed structures in the universe is also wild.
The reason it isn't presented geometrically, by the way, is because over such upsettingly huge distances "geometry" loses some meaning. The current position of everything is more a view through time than actual space. So the map of the universe is much more like a timeline than an explorable map.
At the scale of the map up top, a billion years more or less won't make a huge difference, so it makes fair sense to present it that way. But once you're up to 100 Gy and beyond... shit gets weird.
Wow, that video is fantastic-- never heard of SEA before, will definitely be checking out the rest of his videos now!
SEA, PBS SpaceTime, Astrum, Dr. Becky, Sixty Symbol, and Anton Petrov. With Anton being the one who is very weedsy with a daily video about a recently-published paper. That's the list of YouTubers I think I recommend checking out.
ParallaxNick, man! His videos - mostly about the history of astronomy - are spectacular, poetic, in-depth, thorough.
ParallaxNick has been doing a series of videos on the lives and works of Copernicus, Tycho Brahe, then Kepler, now Galileo, and I assume Newton is next.
I don't know how Anton does it. There is something new every day and each video has tons of detail.
Dont forget cool worlds
His videos are mind-bending. Check out the one on Corrupt Stars.
