But inflation does not really make the universe more uniform — just huge. If inflation is correct, then the billions of light-years that our telescopes probe are a mere dot on a far vaster canvas.

The multiverse comprises a large number of distinct patches, each far bigger than our night sky. What observers see, therefore, also depends on where they find themselves. Most of the regions in the multiverse are inhospitable to life, and their properties will not be observed. But what exactly is life? In order to extract predictions from the multiverse, my colleagues and I have developed a statistical tool to find regions with observers: We look not for life itself but for the disorder left behind by the complex processes that its formation depends on. To understand the physical signatures of life in this way may help us finally to comprehend our own little corner of the multiverse.
