Cosmic web theory is a fundamental concept in the field of cosmology and astrophysics that helps us understand the structure of the universe on the largest cosmic scales. It provides a framework for describing how matter is distributed throughout the cosmos and how galaxies, galaxy clusters, and dark matter interact and arrange themselves within this vast expanse.

At the heart of cosmic web theory is the idea that the universe is not a random collection of galaxies, but rather a complex and interconnected network of cosmic structures. This network is often compared to a spider’s web, where galaxies and galaxy clusters are connected by long, thread-like structures known as filaments. These filaments can stretch for hundreds of millions of light-years, binding galaxies and galaxy clusters together through the force of gravity.
