According to Max Tegmark, a Swedish-American MIT cosmologist,“only Godel-complete (fully decidable) mathematicalstructures have physical existence” http://arxiv.org/pdf/0704.0646v2.pdfHere is his abstract:I explore physics implications of the External Reality Hypothesis(ERH) that there exists anexternal physical reality completely independent of us humans. Iargue that with a suﬃcientlybroad deﬁnition of mathematics, it implies the MathematicalUniverse Hypothesis (MUH) that ourphysical world is an abstract mathematical structure. I discussvarious implications of the ERHand MUH, ranging from standard physics topics like symmetries,irreducible representations, units,free parameters, randomness and initial conditions to broader issueslike consciousness, paralleluniverses and G¨odel incompleteness. I hypothesize that onlycomputable and decidable (in G¨odel’ssense) structures exist, which alleviates the cosmological measureproblem and may help explain whyour physical laws appear so simple. I also comment on the intimaterelation between mathematicalstructures, computations, simulations and physical systems.Richard Ruquist: This is not Bruno's comp because of the assumptionof ERH.

`It is quite close, though, or can be get arithmetically interpreted`

`so. Indeed comp interpreted in arithmetic is really a completeness`

`axiom: p -> Bp. (but not completeness in 1930 sense, it is more Turing`

`completeness). (Gödel's completeness is used, but only as a a`

`simplifying tool).`

`Comp forces the choice of a Turing complete system, which is complete`

`on the computable, but not at all on the provable.`

`Glad to see that Tegmark at last don't take the MUH as axiom. It`

`follows indeed from deeper consideration (on the computable, notably).`

My paper http://vixra.org/pdf/1303.0194v1.pdf, based on Tegmark'sHypotheses, conjectures that only a holographic Metaverse containingmany holographic Universes, contains a sufficient number of bits forcomputations in it to be effectively complete and decidable tocompute matter and energy; whereas the computations in any Universehaving a relatively limited number of bits for computation (ie.,~10^122) are relatively incomplete, and that incompletenesshypothetically results in emergent consciousness. BTW, Ruquist is aSwedish-American name, having been anglicized on Ellis Island.

`That is a complex theory, which if correct, and comp compatible should`

`be derivable from elementary arithmetic. But I am afraid that it`

`negates comp, and is a form of physicalist ultra-finitism. But fair`

`enough, it seems to work (up to now).`

`I am not sure neither you nor Tegmark really appreciate the depth of`

`the FPI rabbit hole in arithmetic, when taking comp enough seriously`

`into account.`

`Tegmark progress in the right direction, but still miss the comp`

`reversal.`

`The physical reality is only in the head ... of the universal`

`machines. Both informally (UDA), and formally (AUDA, the universal-`

`machine's interview, the invariance of physics for the change of the`

`basic phi_i, etc.).`

`There remains an external physical reality, but it is a part of a`

`(greater) real and objective arithmetical reality seen from inside.`

`(and I just argue that this *has to be* the case if we are correct`

`when saying "yes" to the doctor).`

Big Bang theories of Creation point back to such a singularity from which space emerged, and black hole or white hole theories also point to singularities possibly related to creations. Penrose has also proposed the twister, an entity which might possibly have similarities to those events. Recently I have also presented a Platonic, singularity theory of mind, in which the mental or nonphysical produces the phjysical. What if we take Plato seriously and examine the possibility that physical space (spaetime) emerged from the nonphysical ? One might express this is that physical existence has emerged from nonphysical Being or Mind. I am no mathematician, perhaps a mathematical physicist could construct such a theory. Entanglement and Bell's Theorem could be related to this. Dr. Roger B Clough NIST (ret.)
