The Standard Big Bang Model is more or less rooted in the idea that we are not located in some privileged position in space. All observers at the present epoch will see the universe on average the same way that we see it around us. In Steady State Cosmology, not only does the universe look much the same at any location in space, but according to the Perfect Cosmological Principle, it looks much the same at any point in time. There is no evolution of matter, and a dilution of the universe as the expansion proceeds. With this, the Steady State model was created in 1948 by H. Bondi, T. Gold and F. Hoyle. There was no beginning to the universe. It has existed throughout all eternity much as we see it today. It is expanding, but as each galaxy recedes, a new one gradually forms over the eons to maintain the density of galaxies in intergalactic space.
