The cosmological principle states that the universe looks the same everywhere on large enough spatial scales. This means that if you look at patterns and structures in the universe on scales that are large enough, they should look the same whether you are looking at them from Earth or from another galaxy. This is also known as the principle of isotropy and homogeneity. It does not necessarily imply that the universe is expanding at the same rate in all directions, nor does it suggest that there is a unique center of the universe. Additionally, the cosmological principle assumes that physical laws are the same everywhere in the universe.
