I am just looking for an answer to this question-- Does the Many-Worlds Interpretation demand that every physically possible scenario has to be played out somewhere in the Multiverse? David Deutsch has told me that yes this is true (including absurd/ unlikely scenarios...although those would happen with less frequency) And here is what Max Tegmark has said about Many Worlds-- "Things inconsistent with the laws of physics will never happen - everything else will. However, to cheer you up: even if some of your twins hold up gas stations, most of your twins certainly don't, given what I already know about your personality; it's important to keep track of the statistics, since even if everything conceivable happens somewhere, really freak events happen only exponentially rarely". So that is my question. I would love to believe what someone posted earlier...that certain physically possible events WILL NOT happen in the multiverse, but that seems to be at odds with the strictly deterministic nature of this theory.
