I can understand why there is no notion of first person nothingness (and this is the base of the non cul-de-sac appearing with the first person notion(*). But for "everything" I think we can have some third person notions. Typical examples are the complete trace of the running of the UD, written UD*, or a model of PA, ZF, etc. The first person notion of everything (the 1-plenitude) is, assuming comp, so big that it is unnamable by any machine (provably so if the "person" is some fixed not too complex Lobian machine, like a theorem prover for PA). Bruno (*) For those who remembers the modal introduction: a no-cul-de-sac multiverse (a multiverse where all observer-moment/world/state are transitory) verifies the formula []p -> <>p (the so-called deontic formula d). Note that d is not a theorem of G, but is a theorem of G*. d is the well known main axiom for the deontic logic of obligation /permission: indeed a world where d is false is a world where something is obligatory and not permitted. You can put anyone in jail-cul-de-sac there! General question: what do you prefer, as notation (illustrated on the formula d) : Box p -> Diamond p Bp -> Dp []p -> <>p? Are there people who does not see that 1) whatever the truth value of p, Bp -> Dp is true in all the worlds of a non-cul-de-sac multiverse. 2) if Bp -> Dp is true in all world of multiverse, whatever the truth value of p is given in each world, then the multiverse is a non-cul-de-sac multiverse. This is easy. If you don't see this, it means you don't remember the definition of Kripke semantics, or that you don't know classical logic. Modal logic is really the general theory of Multiverses, and other multimultiverses, you know. I hardly doubt we will be able to proceed without getting more familiar with it. I am actually teaching modal logic and students ask me summary notes. I am thinking making them in English and posting them to the list. The post by uv makes me think I should soon or later explain more about Solovay theorem, which makes the link betwwen the metamathematical results of Godel, Lob and the G and G* logics discovered by Solovay, and which are pillar of the interview of the universal machine.

Re: contention: theories are incompatible
Hi Russell, It seems logical. The Notion of "Everything" is 1st person in the sense that one, any one, can find itself within it. Nothing, on the other hand, only makes sense as seen from some external vantage point, hence it is 3rd person. This is probably naive, but it makes the whole structure "hang together". For example, the idea of conservation, ala "you can't get something from nothing", is a truism for the simple reason that it is not consistent to have some concept that is definite, a "something", to be dependent on a Nothing. The notion of something requires an "other" against which it is distinguished; there is no "other" in Nothingness. Onward!

Hi James and Russell, Could a middle ground be found in the notion that "something" is a differentiated piece of Nothing, where Everything (1st person notion) and Nothing (3rd person notion) are one and the same? Violations of the notion of conservation only seem to obtain when we conflate the 1st and 3rd person viewpoints. The problem that I see with existentialism is that it tacitly assumes an unattainable 3rd person upon which to base its notion of existence. Why do we need to assume more than "Existence exists" (in an active and not passive sense)? Onward!

Are conservation principles only defined in closed systems? Is a 'world' a closed system? There is, i.e., a no-deleting theorem (similar to the no-cloning theorem) saying that given 2 qubits in unknown and equal states, one cannot take one of them to a fixed state, keeping the other in the original state. In other terms |psi>|psi> --> |psi>|0> is forbidden. But, of course, it is possible to delete a quantum state by trowing it out of that system, out of that world. s.

Either explicitly excludes and precludes the other; can't have both and retain a consistent existentialism. J Rose I haven't kept up with this thread or that idea, but there is no logical reason that a particular attribute such as "conservation" should be universal across a many-world manifold. First of all, "conservation" is ill-defined, but if precisely defined assumes a standard, which implies a teleological approach. And that is one step away from scholasticism. Before you know it, you're quoting Plato. Mathematically, conservation could be defined in terms of least-distance between points, but if the individual worlds are constructed with their own unique space-time topology (sort of by definition--otherwise each world would be the same as the next one) then the term "conservation" would apply only locally. So, strike two. In fact, one could describe each world as a unique slice intersecting and *forming* the surface of the many-world manifold---and each slice could be characterized by its own unique matrix. Postulating the individual world matrix as a set of elements and interactions between elements, one could arrive at an "ideal" (Plato again!) in which each individual world is confined to a minimum number of elements/interactions. Fine. But it would result in each world being congruent (homologous) to every other world. The result would be no difference between worlds, but there is not a shred of evidence that the configuration works that way at all levels. For example, you coffee may have cooled according to the observations setting forth the laws of thermodynamics---and thus predictable, but you sir, probably drove your automobile in a very inefficient manner today, going places that you shouldn't have gone (you didn't know the queue would be so long, or the store would be closed, etc). Now, if you had known that the store would be closed, etc, you would have been a little more efficient, but that would require a prescience that you presumably don't have. Maybe that's why, we can never precisely predict where the electron will "be", because to do so would identify it's "proper" place---and from there we could then define it's ideal position. That we cannot (as yet) do that suggests that this inability to do so is an inherent part of a dynamic system---and is present within all intersects of the many world manifold. Short answer: Conservatism is a procedure that produces mental constructs of what we thing the world is trying to become. It allows us to fit our observations against the image in our minds, but it has its limitations. There is no perfect river. Or snowstorm. Or politician. It's all in our minds.
