From David Diamond
I was delighted with this article, but it left out a number of issues which make Hugh Everett’s theory of the multiverse even more fascinating.
Suppose I make a choice, and meanwhile an inhabitant of a planet 1 light year away makes an unrelated choice. Are there four universes immediately, or in a year’s time? I would prefer to think that the multiverse phenomenon is local.
Another question: if all universes continue until they reach maximum entropy – in which all energy is evenly distributed – could they then be considered to have merged back into a single universe, since they would all be indistinguishable?
