Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the cosmic structure type?Hierarchical, filamentary, and cellular distribution of matter, dominated by dark matter
2. What is the primary formation mechanism?Gravitational instability acting on primordial density fluctuations in the early universe
3. What is the cosmic web?The cosmic web is a huge network of galaxies and dark matter that looks like a spiderweb in space. It is made of long filaments where galaxies live and big empty spaces called voids.
4. Why do galaxies line up in filaments?Gravity pulls matter together along the filaments. Dark matter creates a hidden scaffold that attracts normal matter, so galaxies form along these threads.

Cosmic Web: The large-scale, three-dimensional distribution of matter in the universe, forming a network of filaments, clusters, and voids.
