Wo sind sie alle? Fünfzig Lösungen für das Fermi-Paradoxon

Translated title of the contribution: Where are they all?: 50 Solutions to the Fermi Paradox

Stephen Webb

    Research output: Book/ReportBook


    There are about a billion Earth-like planets in our galaxy alone. There are about 200 billion galaxies in the visible universe. So doesn't it make sense that somewhere out there a civilization developed at least as advanced as our own? The sheer numbers almost call for it. But then, why haven't we come across messages, artefacts or other clues from just one extraterrestrial civilization?

    In this book, Stephen Webb guides you through fifty convincing and fascinating solutions to the famous Fermi paradox, which are presented in an entertaining way that makes you think and also makes you smile.
