Is There a Parallel Universe?

The word universe has traditionally been used to mean the whole of physical reality. In that sense, there can be at most one universe. A new word, multi verse, has been coined to denote physical reality as a whole, single particle interference. Experiments such as i have been describing show us that the multi verse exists and it contains many counterparts of each particle in the tangible universe. And we'll look in some detail at the further experiment. Ikay, it's more of a thought ment, but potentially could be really done an experiment to refute other ways of understanding quantem theory.
