"Our Universe, the "cosmic web". Each yellow dot is a galaxy. The purple streams represent dark matter."


Now, take for instance our galaxy, the Milky Way. The Milky Way has about 300 billion stars in it. 300 billion. Our own solar system with its 1 star is so incredibly massive, and our galaxy has 300 billion of them. And that galaxy is just a little yellow blip on that picture.


And that picture constitutes 0.000001% of the known universe.

The Hercules–Corona Borealis Great Wall (Her–CrB GW) is an immense superstructure of galaxies that measures more than 10 billion light-years across.[1][2] It is the largest and the most massive structure known in the observable universe.

According to the cosmological principle, any visible random fluctations of the quantities of distribution of matter and energy within the universe will be considered sufficiently small in extremely large scales. This means that the universe will be properly homogenized and isotropized due to the basic assumption that the universe is governed by the same laws of physics regardless of location, space and time.

The Hercules–Corona Borealis Great Wall is more than eight times larger than the scale,[4] and so greatly exceeds the homogeneity scale. In accordance with this, the structure would still be heterogeneous as compared to the other parts of the universe even at the scale of the "End of Greatness", thereby putting the cosmological principle into further doubt.

The structure also poses a problem to the current models of the universe's evolution. A light travel distance of 10 billion light years means that we see the structure as it was 10 billion years ago, or roughly 3.8 billion years after the Big Bang. Current models of the universe's evolution, however, do not allow the said structure to form in just a mere 3 billion years. The structure is itself too big, and too complex, to exist so early in the universe. There is currently no existing model to explain the existence of the structure.

Such large structures like the Hercules–Corona Borealis Great Wall may form part of the vast intergalactic cosmic web, an endless continuous sheet of galaxies and dark matter. Although this web was never directly observed, the relatively large sizes of structures in the nearby universe provides the possibility of the existence of this web. Such gigaparsec-scale structures, including the Hercules–Corona Borealis Great Wall, may be the intersections of smaller subfilaments within this vast structure, where there are overdensities of galaxies connecting other filaments within this vast web. If verified, the Hercules–Corona Borealis Great Wall will be one of the first evidences of the existence of this web.

It's so big that our existence is at what level? Cellular? Atomic? Subatomic?

Is there any such thing as scale? Given how small one can go into the depths of matter.

this is the sombrero galaxy, which looks that way because a supermassive black hole in the center has flattened everything out sort of like a pizza crust when you spin it around. it's believed that what's in that picture are the remains of a small galaxy that was almost entirely eaten by it.

possible, but i don't think it's very likely. if you had a creature in the shape of a human that was the size of the solar system, it would take him hours just to scratch the top of his head because of the distance his arm would have to travel from his waist. there's a theoretical limit on how big a living creature could reasonably be. the fourth dimension also doesn't work that way. people have reasonably calculated what it's like up to the 11th dimension but poo poo gets complicated really quickly.

Solar system? That's tiny! The Universe, man. All of it, is just an atom in some higher dimension.

It's not so far fetched either if you consider the Big Bang Theory.
