Conceptual illustration representing a critical density universe that stays static, with an unknown outcome. After the Big Bang, the universe expanded rapidly during a brief period called inflation, and then evened out to a static density. As the universe expands, the density of galaxies remains more or less constant with spaces filled in by new galaxies. | |
