Hi there! Alright, so let me start off by saying I'm a biochemist by trade, but have an extreme (and possibly unhealthy) interest in the more bizarre aspects of modern physics. Admittedly, I don't understand the mathematical formalisms associated with the theories I know of, so bear with me if I sound a bit daft. I've been interested for quite some time in the Many Worlds Interpretation (MWI) of quantum mechanics first formulated by Hugh Everett, and have now recently become interested in a variation of it called Many Interacting Worlds (MIW). The paper proposing it can be found here. Particularly, my interest lies in whether visiting those parallel universes is theoretically achievable. I'm also intrigued by the work of Mohammed Mansouryar, an Iranian physicist who has proposed a real-life method of opening a traversable wormhole. However, it was recently suggested that there are 10160 observably distinguishable universes in the multiverse. Whether or not we accept this value, I think we can all agree that the number of parallel worlds is very large. Mansouryar, as well as a few others, have proposed ways to actually open a wormhole to a parallel world. But this begs the question of, which world does a given wormhole lead to? And so that gives rise to my ultimate question of whether there are distinctive "addresses" that define the physical relative locations of various universes floating through hyperspace. If such addresses exist, what do they consist of? Are there theoretical ways to "tune" the opening of a wormhole to access a particular one? And can the address of this universe be recorded so as to enable a return journey? Looking forward to seeing how this discussion evolves.
