What is a galaxy filament?
CosmologyLarge-Scale Structure
Quick Answer
A galaxy filament is a long, threadlike structure in the cosmic web made of galaxies, gas, and dark matter. Filaments connect clusters and superclusters across enormous distances.
The Full Story
Galaxy filaments are among the largest known structures in the Universe and are part of the cosmic web, the vast network formed by matter under gravity. They link dense nodes like galaxy clusters and surround huge voids. Computer simulations of structure formation predict this web-like pattern, and surveys of galaxies have mapped many filaments in the real Universe. These structures show how gravity has organized matter over billions of years.
