Parallel universes exist - study
"Parallel universes really do exist, according to a mathematical discovery by Oxford scientists described by one expert as "one of the most important developments in the history of science".
"The parallel universe theory, first proposed in 1950 by the US physicist Hugh Everett, helps explain mysteries of quantum mechanics that have baffled scientists for decades, it is claimed."
I'm pretty sure I don't understand what they mean by "exist". At the level of my sensory perception they don't, but then a lot of reality doesn't "exist" at the level of my sensory perception.
