Thompson describes how contemporary cosmological models consider that the universe begins as a singularity that explodes at a certain point, before exponentially expanding. As the temperature subsequently drops, matter is described as sequentially coalescing into atoms, gas clouds, stars, planets, and finally, organic life. Thompson then follows with a critique of this Big Bang Theory by focusing on one of its fundamental postulates, the cosmic distance ladder.
