The Multiversal Cameraman : A Thought Experiment

[chicar]

1- Quantic physic state than things exist because they are observed.

2- The multiple universe theory imply the existence of a ''earth 0'' who serve of models for all others.

3- ''Earth 0'' had to be the one who is presently observed.

4- But by whom ? Could it be than it exist somewhere a living ''center of the multiverse'' who main purpose is to simply be and act as the prime observer for us all, as the cameraman of the multiversal studio set ? He|Her might be even be self-conscious of his|her state but incapable of sharing the experience without sounding like a sectarian lunatic.

1. Not to be a grammar nazi, but I think you either mean:

Quantum physical state, where things exist because they are observed.

or Quantum physical state, where things exist because they are not being observed.

It goes both ways, because the Wave Function collapses upon observation.  It depends on whether YOUR wave function describes something that exists OR doesn't exist.

The correct terminology is to say that the physical state of things depend on whether it is being observed or not.

2. Why must there be a "universe Zero"?  There is no rule that you have to have a centre... Unless you specify some other rule for the multiverse... For example if I take a multiverse to be a fractal, there may be a starting state, which then is allowed to repeat imperfectly over and over.

3. Since we don't know where that reference universe is, and we are assuming an infinite set of universes, the probability that we are not that universe is asymptotically close to 100% the less we know.  But being quantum mechanics that assumption may change depending on our observations

Well, it only mean than the only proof we would had of a '' earth 0'' would be the discovery of my cameraman.

Just alimenting the debate here.
