A universe is a large cosmic web containing planets, moons, minor planets, stars, clusters, and galaxies. Our universe contains huge clusters of galaxies called hyperclusters, alongside voids with little to no galaxies, and has 4 dimensions (3 of space and 1 of time).
Because of the speed of light, we have yet to confirm other universes exist, but if they do, they might have entirely different strcutures and exist in a multiverse, which may reside in an even larger structure.
Universe is part of a series on verses.
