Cosmic megastructures are the largest known formations in the Universe, spanning billions of light-years and shaping the large-scale structure of the cosmos. These immense structures are composed of galaxies, galaxy clusters, and Dark Matter and Dark Energy, forming a vast cosmic web.
The deeper our technological eyes penetrate into the darkness of the Universe, the more diverse and larger and more complex megastructures we discover. The cosmological principle falters, uniformity, homogeneity seem to require more and more Space to manifest themselves, and with it Time, the supposed age of the Universe predicted by the Big Bang model, which seems less and less sufficient to justify what we observe.
Cosmic megastructures can be classified based on their scale, composition, and formation processes. Here’s a structured classification:
- Galactic Megastructures
- Galaxy Groups: small collections of galaxies bound by gravity
- Galaxy Clusters: structures consisting of hundreds or even thousands galaxies bound together by gravity in turbulent giant Dark Matter / Dark Energy Halo that also contains vast amounts of hot gas
- Superclusters: massive groupings of galaxy clusters
- Large-Scale Cosmic Structures
- Voids: enormous empty regions between filaments, with very few galaxies
- The Cosmic Web: the large-scale structure of the Universe, consisting of interconnected filaments of galaxies, gas, stretching across billions of light-years
- Cosmic Filaments: the largest known structures, consisting of walls of galactic superclusters stretching across billions of light-years
- Cosmic Nodes: dense regions in the cosmic web where multiple filaments intersect. They are among the most massive and evolved regions in the Universe, often containing galaxy clusters
- Galactic Walls: vast sheets of galaxies
- Extreme Megastructures
- Giant Voids or Supervoids: exceptionally large voids
- Large Quasar Groups (LQGs): massive quasar formations
- Gamma-Ray Burst Structures: enormous formations detected via gamma-ray bursts
These structures define the universe’s large-scale organization, influencing cosmic evolution and matter distribution
As mentioned in the previous section, Dark Matter Halos are not "invisible structures surrounding galaxies", but "structural components" of the galaxies themselves, which influence their formation and movement. We confuse the visible part of the galaxy with the galaxy in its entirety, which instead is formed by an invisible structure, a Dark Halo, made of Dark Matter (the internal bubble characterized by negative Mass, negative Perturbation value, lower than average Time flow rate), and Dark Energy (the external shell, but still part of the Dark Halo, characterized by positive Mass, positive Perturbation value, higher than average Time flow rate). The Dark Halo, thus composed, together with the galactic structures formed by Ordinary (visible) Matter "is the galaxy".
The same thing is true for cosmic structures that aggregate galaxies in gravitational systems, the "clusters of galaxies", which, due to their formation and internal and external dynamics, acquire an individual character and in turn become the building blocks that compose even larger and more complex structures, such as superclusters, and also the filaments and nodes that make up the cosmic web.
Let's now look in more detail at two of the most important types of cosmic megastructures, which define the large-scale (obviously turbulent) organization of the Universe, shaping its evolution. I am obviously talking about the voids and the cosmic web, complementary elements that together fill the entire cosmos.
Cosmic structures are the vast, interconnected formations that shape the Universe on the largest scales. They emerge from the gravitational interactions of galaxies, dark matter, and cosmic expansion, forming a cosmic web of filaments, clusters, and voids.

Giant Voids
Gian voids are a fundamental part of the dark cosmic web, a component of the universal (dark and visible) cosmic web.
