Galaxishálózatok

Galaxishálózatok, also known as cosmic web filaments or large-scale structures, represent the largest known structures in the universe. They are vast, interconnected networks of galaxies and dark matter that span billions of light-years. These filaments are not uniform; they are composed of clusters of galaxies, groups of galaxies, and individual galaxies, all bound together by gravity.

The formation of these cosmic webs is thought to have begun shortly after the Big Bang. Tiny quantum fluctuations in the early universe were amplified by inflation, creating regions of slightly higher density. Over billions of years, gravity caused matter to clump together in these denser regions, forming the structures we observe today. Dark matter, which is far more abundant than ordinary matter, plays a crucial role in this process, acting as the gravitational scaffolding upon which galaxies form and cluster.

The space between these filaments is largely devoid of matter and is known as the cosmic void. The distribution of galaxies and matter in the universe is not random, but rather follows this filamentary pattern, resembling a cosmic spiderweb. Studying the structure and evolution of these galaxishálózatok provides crucial insights into the nature of dark matter, dark energy, and the overall expansion and fate of the universe. Telescopes like the Sloan Digital Sky Survey have been instrumental in mapping these vast structures.
