“… any given universe is not actually a thing as such, but is just a way of looking at what is technically known as the WSOGMM, or Whole Sort of General Mish Mash. The Whole Sort of General Mish Mash doesn’t actually exist either, but is just the sum total of all the different ways there would be of looking at it if it did.
The reason they [parallel universes] are not parallel is the same reason that the sea is not parallel. It doesn’t mean anything. You can slice the Whole Sort of General Mish Mash any way you like and you will generally come up with something that someone will call home.” Douglas Adams Mostly Harmless, p. 26
