GANGUI, A.. The multiverse controversy. An. AFA [online]. 2019, vol.30, n.4, pp.72-78. ISSN 0327-358X.

This paper offers a synthesis of the positions in the literature regarding controversies about the multiverse. After reviewing some simple elements of modern cosmology and its observational limitations, we will present the history of the ideas that led, first, to the proposal of the anthropic principle and, years later, to the possible existence of causally disconnected domains, eventually endowed with their own laws and fundamental constants, not all compatible with the existence of observers, which were globally baptized with the confusing name of parallel universes or multiverse.

Keywords : history of science; astrophysics; epistemology.
