I see your point, but Wikipedia isn't super reliable on the more unsettled parts of theoretical physics. For example, a cursory search gives me https://www.tech

I see your point, but Wikipedia isn't super reliable on the more unsettled parts of theoretical physics. For example, a cursory search gives me https://www.technologyreview.com/s/424073/multiverse-many-worlds-say-physicists/ https://www.technologyreview.com/s/424073/multiverse-many-wo..., but while I can't judge https://arxiv.org/abs/1105.3796 https://arxiv.org/abs/1105.3796 on my own, it does appear the idea is new, and for something as new, and as vaguely defined as the multiverse (MWI itself is quite old), I probably should ask for more than a Wikipedia summary. I mean, it's fine by me if there's some kind of disagreement within physics, but to assume they are the same thing would require more, no?
