In a parallel universe, this theory would make sense

This article is worth having a look at if you're an amateur science watcher and have been intrigued or puzzled about quantum physics and multiple universes. While the latter makes for interested sci fi (Sliders and some episodes of Voyager, for example). So in a 'reality check that points out that this theory really is just a theory (and is taken on faith, what's more) and that it falls foul of Occam's razor as things currently stand. Yet maybe one interpretation can hold its head up high: "Oxford physicist David Deutsch, one of the founding fathers of the exciting field of quantum computing, later proposed a variation on Everett's idea in which all possible universes already exist within a quantum multiverse. What we perceive as our reality is just a weaving through this vast shadowy multiple reality, creating our own version of events. While supporters of the multiverse interpretation argue that it is the most sensible explanation, the majority of physicists are sceptical, mainly since it is essentially unprovable."
This is another of those articles where reading the (extensive) comments is actually even more valuable than reading the article that generated them.
