I don't know... something that always bothered me about multiverse theory is that multiverses are supposed to be the explanation for why a lot of our quantum math works out so beautifully.
Matter is continuous into other dimensions, and this is why things like the photon/wave duality can work, interaction with other realities.
In our reality, however, our universe is so sparse as to be almost non-existent (density of the universe is something like 1 hydrogen atom for every 5k cubic meters). This has been measured, and means that our universe is flat (Euclidean).
In my mind, in order to connect the density of the universe with the continuity of quantam behavior, than every reality must have the same density, and flow continuously from ours, which would mean that every reality is Euclidean.
This is where it gets fuzzy for me, because it's my understanding that the multiverse is not Euclidean....
- deciplex 8y agoIsn't this post conflating multiverse hypotheses with the relative-state formulation of quantum mechanics?
- dmayle 8y agoTo be fair, isn't Everett's relative-state formulation the basis/beginning of all multiverse hypotheses?
- deciplex 8y agoIt seems like "multiverse" is used to describe a half-dozen mostly unrelated things or more (just based on the contents of this thread) including among them many-worlds. But, for example, eternal inflation has nothing directly to do with relative-state formulation, nor mathematical universe, nor the "multiverse" where you consider that portion of the universe outside our cosmological horizon to be a separate universe (I wouldn't agree that it is, but apparently that's a thing).
- spiralx 8y agoMax Tegmark has put these ideas into a hierarchy of multiverses, where universes outside of the boundary of the observable Universe are a Type I multiverse, and the many-worlds of the relative-state formulation form a Type III multiverse. http://space.mit.edu/home/tegmark/crazy.html http://space.mit.edu/home/tegmark/crazy.html
