When we look out into the Universe today, it’s no surprise that we find a plethora of planets, stars, star clusters, galaxies and galaxy clusters, as the 13.8 billion years of time that’s passed since the Big Bang has given our Universe ample opportunity to form all of these structures. In fact, given what we’ve determined the composition of our Universe to be, our observations of what we see and our expectations for what ought to be there line up spectacularly well. When we put in the initial conditions we believe our Universe to have begun with and rewind the clock to the very beginning, we can simulate exactly what types of structures we believe are going to form and when.
