Quizplus · Accepted Answer

Superclusters, which are the largest structures in the universe made up of groups and clusters of galaxies, are believed to contain a significant amount of dark matter. Observations and calculations suggest that dark matter constitutes about 85% to 95% of the total matter in the universe, which implies that a similar proportion would be present in superclusters, influencing their gravitational behavior and structure formation.
