In order to get the large scale structure of the Universe we see today, cosmologists have proposed the idea of inflation, that the Universe expanded an enormous amount in the earliest moments. But if inflation really happened, then it has even stranger implications for the nature of the Universe and the search for multiverses. Support Universe Today Podcast
