The Sloan Great Wall is a massive structure of galaxies that is over 1 billion light-years long.

The typical size of a galaxy is about 100,000 light-years.

The typical size of a cluster of galaxies is about 10 million light-years.

The typical size of a supercluster of galaxies is about 100 million light-years.

The distribution of galaxies in the universe is not uniform. Galaxies are clumped together in clusters and superclusters, and they are also arranged in filaments.

The cosmic web is a network of galaxies and clusters of galaxies that is connected by filaments of dark matter.

Dark matter plays a role in both the formation of galaxies and clusters of galaxies, and in the creation of the filaments that connect them.

The future of the large-scale structure of the universe is uncertain. It is possible that it will continue to expand and become more uniform, or that it will eventually collapse in on itself. It is also possible that it will remain the same.

GN-z11 is the most distant object that has ever been observed. It is a galaxy that is located 13.4 billion light-years away.

The Hubble Deep Field is an image of the most distant objects in the universe. It was taken by the Hubble Space Telescope in 1995.

The James Webb Space Telescope is a new space telescope that will study the most distant objects in the universe. It is scheduled to be launched in 2021.

The cosmic microwave background is the leftover radiation from the Big Bang. It is a faint glow that fills the entire universe.

The temperature of the cosmic microwave background is 2.7 Kelvin.

The age of the universe is 13.8 billion years.

The fate of the universe is uncertain. It is possible that it will continue to expand forever, or that it will eventually collapse in on itself. It is also possible that it will remain the same.
