Feynman's Interpretation of Quantum Theory1
H. D. Zeh
URLﾘﾝｸ(arxiv.org)
Feynman said that the concept of a "universal wave function" has serious conceptual
difficulties. This is so since this function must contain amplitudes for all possible
worlds depending on all quantum-mechanical possibilities in the past and thus one is
forced to believe in the equal reality [sic!] of an infinity of possible worlds.
