Phys. Rev. Lett. 81, 5501–5504 (1998)Unambiguous Probabilities in an Eternally Inflating UniverseReceived 23 June 1998; published in the issue dated 21 December 1998 “Constants of nature” and cosmological parameters may in fact be variables related to some slowly varying fields. In models of eternal inflation, such fields will take different values in different parts of the universe. Here, I show how one can assign probabilities to values of the “constants” measured by a typical observer. This method does not suffer from ambiguities previously discussed in the literature. © 1998 The American Physical Society URL:
