Where the Wild Things Are—A Trip to the Pervasive Multiverse and Its Inhabitants

Starting from the very idea of a pervasive multiverse, we analyze what it means conceptually, what things and beings inhabit it, and what rules guide their existence and actions. Next, we provide a psychological and partially philosophical view on this construct and derive some of the risks and opportunities that exist there, eventually leading toward a research agenda for individual and societal concerns and promising approaches to address them in this novel but fast-developing field.
