In the original paper (circa 1957) about the "Relative State Interpretation"
(now "Many Worlds Interpretation") H. Everett III does not say that
all possible world histories are *real* or equally *real*.
Gell-Mann, in example, says that every each world history has,
as usual, a probability attached.
Otherwise it is not easy to normalize, that is to compute the entropy
involved in a quantum measurement.
Papers about "Many Worlds or Many Words?".
