THE UNEVEN UNIVERSE
“It is almost always assumed in cosmological calculations that there is a even distribution of matter in the universe. This is because the calculations would be much too complicated if the position of every single star were to be included. In reality, the universe is not uniform: in some places there are stars and planets, in others there is just a void.”
