This is a much simpler description for the shape of the universe than what's called the "Standard Model." Instead of assuming that the galaxies only "seem" to be moving away from us, it really just assumes that everything actually IS moving away from us. This model uses the Special theory of Relativity, Lorentz Transformations, and the idea of a "secondary bang" to explain some of the large-scale features of the universe.
