Due to the accelerating expansion of the universe, the individual clusters of gravitationally bound galaxies that make up galaxy filaments are moving away from each other at an accelerated rate; in the far future they will dissolve. [2] Galaxy filaments form the cosmic web and define the overall structure of the observable universe. [3] [4] [5]
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres). This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension.
The structure of the Universe can be broken down into components that can help describe the characteristics of individual regions of the cosmos. These are the main structural components of the cosmic web: Voids – vast, largely spherical [6] regions with very low cosmic mean densities, up to 100 megaparsecs (Mpc) in diameter. [7]
Artist's logarithmic scale conception of the observable universe with the Solar System at the center, inner and outer planets, Kuiper belt, Oort cloud, Alpha Centauri, Perseus Arm, Milky Way galaxy, Andromeda Galaxy, nearby galaxies, Cosmic web, Cosmic microwave radiation and the Big Bang's invisible plasma on the edge. Celestial bodies appear ...
New astronomical research is beginning to reveal an invisible scaffold of dark matter known as the Cosmic Web, an intergalactic network that transformed the universe from a chaotic Big Bang into the structured beauty of the present day cosmos.
Assuming the universe keeps expanding and it does not suffer a Big Crunch, a Big Rip, or another similar fate, the cosmic microwave background will continue redshifting until it will no longer be detectable, [112] and will be superseded first by the one produced by starlight, and perhaps, later by the background radiation fields of processes ...
The universe is viewed as "meta-galaxies" divided by double layers and thus a bubble-like nature. Other universes are formed from other bubbles. Ongoing cosmic matter-antimatter annihilations keep the bubbles separated and moving apart preventing them from interacting. Brans–Dicke theory: Carl H. Brans, Robert H. Dicke: Expanding Based on ...
The Hercules–Corona Borealis Great Wall (HCB) [1] [5] or simply the Great Wall [6] is a galaxy filament that is the largest known structure in the observable universe, measuring approximately 10 billion light-years in length (the observable universe is about 93 billion light-years in diameter).
