The connection defines parallel transport of tensor/spinor fields relative to a given symmetry group G that keeps the global dynamical action of matter fields (classical and quantum including strings and branes) invariant.

The transformations of G need physical definition in terms of measurements at least in sense of gedankenexperiments if not actual technologically achievable measurements.

The most well known anholonomic connection is the vector potential Cartan 1-form A in the G ---> U1 fiber bundle.

The kinetic momentum of a charged particle is

mv = P - (e/c)A

P is the canonical momentum in the Lagrangian formulation

A is the field momentum attached to the charge - needed for local momentum/energy conservation

mv is gauge invariant!

The Abelian gauge transformations are

A --> A' = A + df

f = 0-form

d^2 = 0

When

F = dA =/= 0

A is said to be anholonomic (or non-holonomic)

F = electromagnetic field Cartan 2-form.

In vector calculus F is the 4D curl of A in the Minkowski spacetime of special relativity.

The de Rham integral of A over a closed 1-cycle is detectable as an interferometer fringe shift on charged test particles even if F = 0 on the paths of the particles. This is the Bohm-Aharonov effect.

The generalized Stoke's theorem is:

Integral of the exterior derivative of a p-form over a (p + 1)-co-form (domain of integration) = integral of the p-form over the p-boundary of the (p + 1) co-form (aka "chain" in sense of topological complexes in a discrete version of the manifold like in lattice gauge theory of quantum chromodynamics, Ken Wilson's renormalization group flows on a lattice etc).

Therefore, in the special case of the Bohm-Aharonov effect the enclosed quantized magnetic flux has a nonlocal influence on the quantum phase of the charges in the F = 0 region. Either that, or A is a local observable. More precisely, the equivalence class of A's connected by the df gauge transformation is the local observable.

In the case of the electromagnetic U1 there is no direct way to measure A locally. The situation is not clear to me for SU2 & SU3.

D = d + A/\ = exterior covariant derivative operator

F = DA = dA + A/\A

In the case of gravity there is a local measurement of the connection analogous to A.

In the case of Einstein's 1916 gravity A -->  spin-connection A^I^J

F = gravity curvature Cartan 2-form.

For example 1

Including the indices for SU2 & SU3 weak-strong forces

F^a = dA^a + f^abcA^b/\A^c

f^abc are the structure constants of the Lie algebra commutators of the charges Q^a

[Qb,Qc] = f^abcQa

Another example 2 gravity (raise and lower indices I,J,K with the Minkowski metric nIJ)

F^I^J = dA^I^J + A^IK/\A^KJ

A^I^J = -A^J^I = gravity spin connection Cartan 1-form

all of these quantities are GCT LOCAL "GAUGE" INVARIANTS!

The relation to the Levi-Civita connection is indirect and complicated - see Rovelli Ch 2 "Quantum Gravity" (free version online).

I,J,K are indices for the 1905 SR Poincare symmetry Lie group P10 generated by total energy, linear momentum, angular momentum, boosts forming the Lie algebra of "charges."

The spin connection is not a tensor under the Lorentz SO1,3 subgroup of P10.

Example 3 thermodynamics.

The thermodynamic manifold is not in space-time but with respect to a set of intensive-extensive coarse grained conjugate pairs like

T S (temperature - entropy)

u N (chemical potential - particle number)

stress-strain

magnetization-magnetic field (magneto-striction)

the intensive variables are Lagrange multipliers in Legendre transformations etc.

We are given a thermodynamic 0-form E

E is a sum of conjugate pairs.

With 1-form

dE

d^2E = 0 are called the Maxwell relations.

This vanishing curl in the thermodynamic manifold is analogous to zero curvature in gravity and zero electric and magnetic field in Maxwell's theory.

However, new physics will introduce a non-coordinate thermodynamic connection A where

d^2 = 0

but D^2 =/= 0

local experiments measure D not d

i.e.

D = d + A

DdE = d^2A + A/\dE = A/\dE =/= 0

this will look like an apparent violation of the naive Maxwell relations that presuppose a "coordinate" holonomic connection.

New time travel logic paper 3-7-12

Without taking sides about the physical possibility of chronology violations, in this paper we will show that, from a logical viewpoint, the so-called time travel paradoxes may be seen as a consequence of the fact that, in presence of chronology violations, we insist on the adoption of the usual Temporal Logic. The adoption of suitable unusual Temporal Logics allows to get rid of any mathematical inconsistency.
Indeed not only the affection of the past but even its change can be formalized by suitable consistent Temporal Logics.

A curious feature of General Relativity is that there exist solutions (M, gab) of Einstein’s equation such that
Vchronology(M, gab) 6= ∅. The so called time travel paradoxes then occur.

[Jack: not so, for example the papers of Novikov, Kip Thorne on globally self-consistent paradox-free loops. OK see "2" below.]

These paradoxes can be divided in two classes:

• consistency paradoxes involving the effects of the changes of the past (epitomized by the celebrated Grandfather Paradox in which a time-traveller goes back in the past and prevents the meeting of his grandfather and his grandmother)

[Jack: See also papers by Deutsch, Seth Lloyd.]

• bootstrap paradoxes involving the presence of loops in which the source of the production of some information disappears (as an example let us suppose that Einstein learnt Relativity Theory from [1], [2] given to him by a time-traveller gone back to 1904).

[Jack: This is not a paradox at all. Indeed, it is the back-from-the-future signal nonlocality mechanism for human creativity already glimpsed in Bem's ---> Libet's presponse data - in my opinion.]

They has been faced by the scientific community in different ways (see the fourth part ”Time Travel” of [3] as well as [4]):
1. adding to General Relativity some ad hoc axiom precluding the physical possibility of causal loops (such as the strong form of Penrose’s Cosmic Censorship Conjecture)
2. appealing to consistency conditions (such as in Novikov’s Consistency Conjecture) requiring that causal loops, though allowing causal influence on the past, don’t allow alteration of the past
3. arguing that the problem is removed at a quantum level (such as in Hawking’s Chronology Protection Conjecture
[5] stating that the classical possibilities to implement time-travels are destroyed by quantum effects)
4. arguing that the so called time-travel paradoxes are only apparent and may be bypassed in a mathematical
consistent way
As to General Relativity we think that discarding tout court non globally-hyperbolic solutions of Einstein’s equation considering them ”unphysical” is a conceptually dangerous operation:
in presence of ”unphysical” solutions of physical equations we have always to remember that our intuition is not a neutral quality but is affected by the Physics to which we are used.
Consequentially, in presence of new Physics, it is natural that it appears to us as counter-intuitive.
If Dirac had discarded as ”unphysical” the negative-energy solutions of his equation he would have never predicted the existence of anti-matter [6].
While we agree with Visser’s [4] idea that solutions with ”non-localized” chronology violating set may be seen as produced by a sort of garbage in-garbage out phenomenon (where the garbage in are perverse initial-value conditions and the garbage-out are the resulting perverse solutions) we think that solutions with ”localized” chronology violating set should be taken seriously.
Of course, depending on the precise mathematical definition that we adopt for the term ”localized”, we may arrive to different conclusions.
A minimal definition of the term ”localized” would consist in imposing that Vchronology(M, gab) 6= M.
This is sufficient to discard G¨odel’s solution, the Van Stockum - Tipler time machine, some spinning cosmic
string time machine but not Gott time machine that may be excluded only assuming a more restrictive definition of ”localized” as ”suitably bounded”.

An other argument often used in the literature consists in the refutal as ”unphysical” of any non asymptotically-flat space-time; this is (at least) curious: the fact that asymptotically flatness is a condition required in order to be able to define a black-hole (as the complement of the causal past of future null infinity B := M − J−(I+)) is not a good reason to assume as ”physicality”’s criterion one incompatible with the assumption of homogeneity and isotropy under which the Friedmann-Robertson-Walker solutions of Classical Cosmology are derived.

Finally we agree with the Headrick-Gott’s [7] refutation of the claim that the observed absence of time-travellers

[Jack: Some UFO investigators of sound mind disagree here as to what the evidence is.]

in the present and in the past would be an empirical datum supporting the physical impossibility of time-travel:
no experimental fact on M − Hchronology(M, gab) can be used as an argument in favour or against the hypothesis
that Vchronology(M, gab) 6= ∅.

When also Quantum Mechanics is taken into account we again agree with Visser’s viewpoint [4] according to which the Kay-Radzikowski-Wald singularity theorems (stating that in presence of a non-empty chronology-violating set there are points of the chronology horizon where the two-point function is not of Hadamard form [8], [9]) has to be interpreted not as a support of Hawking’s Chronology Protection Conjecture but as an evidence of the fact that in such a situation Semi-classical Quantum Gravity (defined as Quantum Field Theory on a fixed curved background augmented with the semi-classical Einstein equation Rab12Rgab = 8 <  | ˆ Tab|  > taking into account the backreaction of the quantum fields on the spacetime’s geometry [10]) is not a good approximation of Quantum Gravity.

Hence we think that the status of Hawking’s Chronology Protection Conjecture may be decided only at the Quantum Gravity level.

Since most of the phenomenology of Quantum Gravity is detectable only at the Planck scale (lengths of the
magnitude of the Planck length lPlanck10−33 cm, energies of the magnitude of the Planck energy EPlanck
1019 GeV ) that is enormously far from our present possibility of experimental investigation, the quantum status of Hawking’s Chronology-Protection Conjecture may be at present investigated only on a theoretical basis, all the rival alternative proposals (String Theory [11], [12], Loop Quantum Gravity [13], Connes’ Quantum Gravity [14], [15], Simplicial Quantum Gravity [16], Prugovecki’s Quantum Gravity [17], Finkelstein’s Quantum Gravity [18], ÅE ÅE ÅE ) being far from giving, on this issue, clear and univocal answers.

Denial Logic
Authors: Florian Lengyel, Benoit St-Pierre
(Submitted on 2 Mar 2012)

  Abstract: We define Denial Logic DL, a system of justification
logic that models an agent whose justified beliefs are false, who
cannot avow his own propositional attitudes and who can believe
contradictions but not tautologies of classical propositional logic.
Using Artemov's natural semantics for justification logic JL, in which
justifications are interpreted as sets of formulas, we provide an
inductive construction of models of DL, and prove soundness and
completeness results for DL. Some logical notions developed for JL,
such as constant specifications and the internalization property, are
inconsistent with DL. This leads us to define negative constant
specifications for DL, which can be used to model agents with
justified false beliefs. Denial logic can therefore be relevant to
philosophical skepticism. We use DL with what we call coherent
negative constant specifications to model a Putnamian brain in a vat
with the justified false belief that it is not a brain in a vat, and
derive a model of JL in which "I am a brain in a vat" is false. We
define the fusion of Denial Logic with the Logic of Proofs to model an
agent who can justify and check tautologies and who can believe his
justified false beliefs. Denial Logic was inspired by the contemporary
debate over anthropogenic global warming

The thing doesn't look like a machine at all, but the view seems customized for beings like ourselves. I have not heard of another person reporting this though I've discussed it with Russell and Kit.

I somehow  saw and accessed this while awake on February 12, 2011 in Cambridge (Mass.). The computer can be accessed and questions asked non-verbally, which I did and it tailored the information to fit the question. The information is displayed in multiple ways to be accessed immediately at a glance. It is the living Valis, perhaps built by our own descendants or is being displayed from the future. It is meant to be accessed by many beings at once.

Bohm and Hiley rather gave up on quantum potential, but you could consider it as the basis of implicate order, or maybe the cells of some superorganism.  

I conceive of the implicate order as the Seth Lloyd computer from the 10^123 Planck area pixels on the asymptote of the de Sitter future horizon. The explicate interior bulk is essentially some kind of Fourier transform of the processing on the horizon.


I'm trying to take these ideas further at this time. The point about a community is that it can have a more global effect than an individual, which is related to dissemination of discoveries.

From Brian's paper:

"Mathematical precision
One important issue is how mathematical precision emerges from a system
that is initially very imprecise. We can usefully consider in this connection
Euclidean geometry, a mathematically precise system that emerged through
the consideration of properties of the world that were not known with any
great precision. Geometry, like any mathematical enterprise, is a symbolic
activity that does not depend in any essential way on interaction with
the world. It was, nevertheless, inspired by knowledge of real point-like
objects and approximate straight lines. By retreating into symbolism one
escapes inconvenient facts about the world and is able to create a system
that has a certain resemblance to the world even though there is no exact
correspondence. The Euclidean plane, is in essence, a fantasy that one can
address through symbols even though the real world does not correspond
exactly to it. However, in this case the correspondences between the
Euclidean world and the real world are sufficiently close that Euclidean
geometry is of value in the real world, but this is something that has to be
discovered through observation rather than taken for granted.


Generation of space and physical universes
In our ordinary world, Euclidean geometry is simply a system that provides
a good model for phenomena in space, using specialised techniques to
connect the model with the reality. From the perspective of our primordial
community, it conversely provides a model for forming a universe-system
(more generally, physical laws provide a basis for forming the corresponding
physical reality)."


What is the "primordial community" some sort of intrinsic mental field, like a cosmic scale Bohm quantum potential perhaps?
In my retro-causal hologram variation on the theme of 't Hooft and Susskind, the hologram screen consists of both our future and past cosmological horizons in the precise sense of Tamara Davis's PhD (online).



T. Davis Fig 1.1c

As suggested by Seth Lloyd the black hole horizon is a computer with channel capacity of A/4Lp^2 BITS. I am not clear if Seth means C-BITS or Q-BITS. I will assume he means Q-BITS.

We are outside black holes, but we are inside both of our cosmic horizons. Our future horizon is the past light cone of our proper timelike infinity. Our past horizon is the future light cone of the moment of inflation from unstable false vacuum sans gravity to metastable vacuum with emergent IR gravity. The area of our future horizon saturates (middle thin solid line below)





Now, do the emergent horizons contain Brian's "units"? Q-BITs?

Only our future dS horizon's asymptote gives the right number for the dark energy density hc/Lp^2A. Our past horizon is not at all dS. Therefore, we need the Wheeler-Feynman mechanism with our future horizon as the total final absorber for

Causality without causality.

i.e. "retarded" past to future

BJ continues:

"The model is not the technology, any more than
understanding the sphere equates to the existence of physical spheres. We
hypothesise however that some such technology, which in due course we may
ourselves be able to understand, was discovered at the primordial level, and
forms the basis upon which physical universes are generated. Mathematical
precision exists only in the world of discourse, and is realised to whatever
degree is possible by technology.

Symmetry and symmetry breaking may play a key role here, in view of
the fact that conceptually symmetry is defined in terms of transformations
that may have physical correlates, while at the same time symmetry is found
to play an important role in actual physics."


Indeed, the entire classical world consists of spontaneous broken symmetries.

Space crystals are SBS T3 ---> discrete crystal space groups with momentum UMKLAPP scattering

VIRTUAL PHONONS k =/= 0 & f = 0

k = 1/lattice vectors

Time crystals (Wilczek) are SBS T1 ---> discrete 1-dim lattice group with energy UMKLAPP scattering

VIRTUAL GOLDSTONE-HIGGS QUANTA with f =/= 0 and k = 0

f = 1/period of repeated motional pattern in ground state

All SBS condensates that form the skeletons of the classical world are made from condensates of VIRTUAL GOLDSTONE-HIGGS quanta.

BDJ:

"In this picture locality is understood as an emergent property, analogous
to the frequency of a physical process. Just as in some circumstances frequencies
of physical processes become well defined, with different frequencies
becoming independent of each other as far as linkages are concerned, in
this case location becomes a well defined quantity, with different locations
becoming independent of each other. Quantum entanglement and wholeness,
on the other hand, would be derivative of the units of circular theory. More
generally, the high degree of correlation associated with the packing model
can be expected to be manifested in phenomena similar to those associated
with quantum mechanics.

Discussion
We have addressed in a natural way Wheeler’s question of how observerparticipation
can lead to the emergence of specific laws of nature in
particular systems. The key point is the fact that the interpretation of
signs changes the game, facilitating the emergence of new kinds of system
and process, which are correlates of cognitive and cultural development
that, in the present context, lead to emergent laws. In this picture, the
responsible system or systems are the determiners of the observed laws,
rather than the laws concerned being presumed absolute, or derivable from
some mathematical analysis.

One can imagine a scenario whereby conventional science would be forced
similarly to renounce the idea of a Final Theory. We already have a situation
where some theory X (e.g. the Standard Model) proves inadequate and
theory Y (e.g. string theory) is proposed to take its place. Then certain
further issues lead to the idea that the real ‘fundamental theory’ is Z (e.g.
M-theory). At each stage, however, the supposed fundamental theory gets
farther from what is accessible by experiment, and its connections with
reality become more obscure.

The idea that nature at some deeper level has biological aspects is not
fundamentally absurd, and has been previously explored by authors such as
Smolin[7] and Pattee[8]. The above analysis has explored some aspects of the
‘biological logic’ applicable to such a scenario, in particular the mechanics
of development, which could lead to what might be termed ‘extended
mind’. Faculties such as mathematical intuition, difficult to account for
in conventional ways, might be manifestations of the extended mind, which
might also be related to experiences of meaning in art.

To what extent can these proposals be considered scientific in character?
While the absence of a fixed, universal mathematical law may seem at first
sight to be a radical departure from scientific tradition, the idea that the
laws manifested in the laboratory are emergent rather than fundamental is
already a feature of string theory. And, as practiced, biology is a science
that makes extensive use of phenomenology (e.g. that of chemical reactions),
and concepts specific to biology, and typically makes less use of the methods
of theoretical physics (i.e. mathematical models).

A typical biological concept is the idea that particular systems (e.g.
the immune system) have particular functions. Such concepts have value
in interpreting what one finds and in guiding investigations. The ideas
expounded here can be expected to be of similar value in constructing models
where conventional methods prove inadequate.

Some scientists have accepted the idea that not everything can be
characterised in quantitative terms, asserting however that the only real
knowledge is that based on scientific measurement; but alternatives [1, 9],
offering a broader understanding of what constitutes knowledge, are possible.
The present discussion offers some insight into what is involved in that latter
position. Nature is pervaded by patterns (signs) which through practice we
have become expert in interpreting, a process that has pragmatic value even
if it is not amenable to the traditional quantitative methodology. If the
picture developed here is correct, there is much more in the way of meaning
to be found in the natural world by such means than can be found through
the traditional methodology of science.

One must stitch the past and future solutions together.
This is discussed in Tamara Davis's thesis.

BDJ: Bohm and Hiley rather gave up on quantum potential, but you could consider it as the basis of implicate order, or maybe the cells of some superorganism

JS: I conceive of the implicate order as the Seth Lloyd computer from the 10^123 Planck area pixels on the asymptote of the de Sitter future horizon. The explicate interior bulk is essentially some kind of Fourier transform of the processing on the horizon.

BDJ: I'm trying to take these ideas further at this time. The point about a community is that it can have a more global effect than an individual, which is related to dissemination of discoveries.

    • Ulla Mattfolk During the 1950s, Wheeler formulated geometrodynamics, a program of physical and ontological reduction of every physical phenomenon, such as gravitation and electromagnetism, to the geometrical properties of a curved space-time. Aiming at a systematical identification of matter with space, geometrodynamics was often characterized as a continuation of the philosophy of nature as conceived by Descartes and Spinoza. Wheeler's geometrodynamics, however, failed to explain some important physical phenomena, such as the existence of fermions (electrons, muons, etc.) or that of gravitational singularities. Wheeler therefore abandoned his theory as somewhat fruitless during the early 1970s.

      Maybe he used the wrong concept for the unification? Why are forces qubits? Behind a force is a particle!

    • Mollyann Wingerter In classical physics a bit is information. In quantum physics information is a qu-bit. In a quantum computer, a quantum logic gate processes both up and down or zero and one bits at a time. This leads to increase in processiing power provided it does not effect the system. In a qubit all directions are possible because it is a particle that is behind it therefore it has the ability to exist as a superposition of different states.

    • Michael McNeil Geometrodynamics is simply another name for general relativity. See, e.g., Misner, Thorne, and Wheeler's massive tome Gravitation from the 70's, where the two terms are used interchangeably.

    • Jack Sarfatti Wheeler's GMD is based on GR of course, but goes beyond Einstein's 1916 version as Ulla correctly descirbes above. Of course Wheeler was with Einstein at Princeton and Einstein knew what Wheeler was doing.

    • Jack Sarfatti Yes, GMD was a failed program as Ulla says, though parts of it may rise again, but of course, with quantum theory in Bohm's ontological interpretation and Abdus Salam's strong short-range Yukawa f-gravity that has reappeared in the extra-space dimensions of string theory.

"(in certain models) it is transparent that the origin of the gravitational coupling constants has nothing to do with ideas like 'vacuum energy' or statements like 'energy gravitates', because energy itself is an emergent concept."

Art please understand I have the only viable solution of this problem.
It needs retrocausality.
Seth Lloyd said on 2-27-12 he knew my result was mathematically sound.
I mean the de Sitter redshift of hc/Lp^4 ---> hc/Lp^2A
however Seth could not believe it was the future horizon, he thinks, like they all do that it's the past particle horizon.
That won't work. Our past horizon is not de Sitter.
One must stitch the past and future solutions together.
This is discussed in Tamara Davis's thesis.

Yes, emergence of the metric from the condensate I obviously agree with and have given a model for that. I need eight Goldstone phases in the post-inflation vacuum to get Einstein's GR field equations emergent in the Cartan form tetrad-spin connection formalism of Rovelli's Ch 2 of "Quantum Gravity."

Indeed, the entire classical world is emergent from different kinds of ground state condensates. That's P.W. Anderson's "More is different."
