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 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).
Maps of the long filaments of gas that hold the universe together may one day help us trace and unveil 'dark matter'. Scientists start mapping the hidden web that scaffolds the universe Skip to ...
The model makes it clear to see how the matter-dense regions contract under the collective gravitational force while simultaneously aiding in the expansion of cosmic voids as the matter flees to the walls and filaments. Cosmic voids contain a mix of galaxies and matter that is slightly different than other regions in the universe.
The Great Wall (also called Coma Wall), sometimes specifically referred to as the CfA2 Great Wall, is an immense galaxy filament.It is one of the largest known superstructures in the observable universe.
Physical cosmology is a branch of cosmology concerned with the study of cosmological models. A cosmological model, or simply cosmology, provides a description of the largest-scale structures and dynamics of the universe and allows study of fundamental questions about its origin, structure, evolution, and ultimate fate.
