Going to piggyback with a question unrelated to yours but tangental to the topic:
What about the universes in the multiverse where 'multiverse theory' is wrong, and there is no multiverse? Are they islands? Are they like multiverse 'diodes' which may allow only one-way travel into that universe, but from which return to the larger multiverse is impossible?
- jakeva 9y agoThis sounds a lot like the question of "does the set of all sets contain itself?" which is naturally a part of Russell's paradox. I can't offer more, but I don't think the concepts are dissimilar.
- AgentME 9y agoJust to clarify something: the standard many-worlds interpretation (such as discussed in the original article and elsewhere in this thread) doesn't contain anything about other alternate branches having different physical laws or being fundamentally different, and in MWI the only way that branches interact with each other is that probabilities are affected when multiple branches have their physical states match up completely (after possibly taking different paths) -- there's no way for intelligent beings to interact with meaningfully different branches for example. The many-worlds interpretation isn't a baseless what-if-there-are-alternate-universes thought experiment that anything could happen in, but instead is arguably the straight-forward interpretation of what we know about quantum mechanics.
