MW: Multiverses have been used by a number of people for a number of things.
I was alluding to the work of Everett. His hypothesis relates to the
question of Schrodingers cat, where according to the Copenhagen convention,
it is by observing that you determine whether the cat is dead or not.
Everett's hypothesis is that there are two worlds, one in which the cat is
dead, the other in which it is alive, and that both these worlds are real.
We just don't know which one we are in until we open the box. (03)
