    Jason,

    Answers to your 3 questions.

    1. No.


If there are no faster-than-light (FTL) influences, then how does your interpretation address the EPR paradox ( http://en.wikipedia.org/wiki/EPR_paradox )? As a previously mentioned, according to Bell's theorem, there is only one known solution to the paradox that does not involve FTL influences, and that is Everett's theory of many-worlds.

That's not really true. If you look at the wikipedia table that you cited, http://en.wikipedia.org/wiki/Interpretations_of_quantum_mechanics you see that Popper's, time symmetric, many-minds, consistent histories, and the relational interpretation are all local, i.e. no FTL. To that I would add the purely epistemic "non-intepretation" of Peres and Fuchs.

    2. Determined by which observer? The cat is always either dead or alive. 
It's just a
    matter of someone making a measurement to find out.


So are you saying that before the measurement the cat is neither alive nor dead, both alive and dead, or definitely alive or definitely dead? If you, (and I think you are), saying that the cat is always definitely alive or definitely dead, then about about the radioactive atom? Is it ever in a state of being decayed and not decayed? If you say no, it sounds like you are denying the reality of the superposition, which some interpretations do, but then this leads to difficulties explaining how quantum computers work (which require the superposition to exist).

Superposition is just a question of basis. An eigenstate in one basis is a superposition in another.

    3. Of course quantum computers are possible. Simple examples already exist, 
but
    fundamentally all computations take place in logical information space, as 
I've
    described before in a number of posts.


If a quantum computer can factor a randomly generated semi-prime of 1,000,000 digits, where is the computation for this being performed? This is a computation that is so complex that no conventional computer (even the size of the universe) could solve this problem if given a trillion years, yet a device that could fit on your desk could solve it in less than a second. If the exponentially exploding states in the superposition are not really there, there is apparently no explanation at all for where the result of the computation comes from.

However, keep in mind that all this computation takes place in this world, otherwise the processes could not interfere and converge to a (probable) answer.

    However I don't think the answers to these questions will help you 
understand the
    theory. Refer to my other topic on this group titled "Yes, my book does 
cover
    quantum reality", or refer to the book itself, or I can explain further....


Thanks. I may not have time to read your book for some time, so for now I would prefer to proceed by e-mail, at least until some resolution is reached. I appreciate the time you have spent so far in answering my questions.

Jason

            All,

            I'm starting a new topic on wavefunctions in this reply to Jason 
because he
            brings up a very important issue.

            The usual interpretation of wavefunctions are that particles are 
'spread
            out' in the fixed common pre-existing space that quantum theory 
mistakenly
            assumes, that they are superpostions of states in this space.

            However in my book on Reality in Part III, Elementals I propose 
another
            interpretation, namely that particles are discrete information 
entities in
            logical computational space, and that what wavefunctions actually 
are is
            descriptions of how space can become dimensionalized by decoherence 
events
            (since decoherence events produce exact conserved relationships 
between the
            dimensional variables of interacting particles).


        I am not sure that I follow, but it sounds like an interesting idea. It 
reminds
        me of Ron Garret's talk, where he says metaphorically "we live in a 
simulation
        running on a quantum computer": 
http://www.youtube.com/watch?v=dEaecUuEqfc

            The mathematical results are exactly the same, its just a different
            interpretation.


        I am not sure if it is possible in any theory consistent with QM to deny
        completely the notion of superposition. How can the single-electron 
double-slit
        experiment be explained without the electron being in more than one 
place at the
        same time?

        I think it would help me understand your interpretation if you answered 
the
        following questions. According to your interpretation:

        1. Are faster-than-light influences involved?
        2. When it is determined whether or not Schrodinger's cat is alive or 
dead?
        3. Are quantum computers possible, and if so, where are all the 
intermediate
        computations performed?

        Jason


            However this approach that space is something that emerges from 
quantum
            events rather than being a fixed pre-existing background to events 
enables
            us to conceptually unify GR and QM and also resolves all so called 
quantum
            'paradox' as quantum processes are paradoxical ONLY with respect to 
the
            fixed pre-existing space mistakenly assumed.
