This chapter reviews a collection of other philosophical and conceptual consequences of the Everett interpretation: the popular-science idea that chaos theory makes the future sensitively dependent upon our present actions; some exotic situations involving quantum probability, such as the infamous ‘quantum suicide’ thought experiment; the proposal by Deutsch that other worlds are directly observed in quantum-mechanical interference processes; the ontologica status of mixed states; and the nature of time travel in an Everettian universe.

Keywords: Everett interpretation; many worlds; probability in quantum theory; David Deutsch; chaos theory; quantum suicide; time travel; mixed states
