if you use static coordinates
gtt = 1 - r^2/A
1 + z = [gtt(receiver)/gtt(source)]^1/2
use r ~ A^1/2 - Lp in gtt(source) and r = 0 for gtt(receiver)
for advanced offer wave in the Cramer transaction
result is (first order Taylor series)
1 + z ~ (1/(Lp/A^1/2)^1/2) = (A^1/2/Lp)^1/2
---> infinity as Lp ---> 0
My argument in co-moving Friedmann coordinates below is consistent with the in static coordinates above.
As above
So below ;-)
Indeed Tamara Davis in her PhD says what I say about the change of distance to our past and future horizons It's obvious from her diagram (Fig 1.1)
We recede from our past particle horizon, we approach our future dark energy de Sitter horizon.
1) In a Cramer transaction a retarded offer wave to us from near our past horizon is redshifted.
An advanced confirmation wave from us to near our past particle horizon is blue shifted.
Our relative space is effectively expanding forward in time in this transaction with our past horizon.
2) In a Cramer transaction an advanced offer wave to use from our future horizon is redshifted.
A retarded confirmation wave from us to it is blue shifted.
Our relative space is effectively contracting forward in time in this transaction with our future horizon.
Therefore, it is effectively expanding backwards in time for a back from the future advanced wave to us.
Advanced Wheeler-Feynman Hawking black body radiation of peak energy hc/Lp is then redshifted down to hc/(LpA^1/2)^1/2 at our detectors.
From Stefan-Boltzmann T^4 law this gives energy density hc/Lp^2A, which happens to agree with the actual dark energy density accelerating out causal diamond observable patch of the multiverse.
A = area of our future horizon at intersection with our future light cone.
The co-moving distance from us to our future horizon decreases forward in time.
The co-moving distance from us to our past horizon increases forward in time.
Virtual electron-positron pairs "stuck" on our future horizon are properly accelerating unlike real co-moving charges with zero proper acceleration AWAY from us. Therefore, using Doppler analogy radiation from them to us is redshifted. The virtual pairs are elevated to real pairs by the very hot Unruh radiation they feel locally. This is all in relation to us distant observers according to Susskind's "horizon complementarity".
proper acceleration of the virtual electron positron pairs stuck on the horizon is
g(r) = -(c^2/2)gtt^-1/2dgtt/dr
in static LNIF coordinates ONLY
gtt = 1 - r^2/A
dgtt/dr = -2r/A
g(r) = +c^2(1 - r^2/A)^-1/2r/A
note that we are at r = 0.
IN CONTRAST, for comoving sources in usual FRW coordinates gt't' = 1 so g'(r) = 0.

Report from London: My prediction of a second high frequency Hawking radiation signal
Posted by: JackSarfatti |Tagged in: Unruh effect, Hawking radiation, de Sitter horizon, Dark Energy, Black Hole
Jack Sarfatti proper acceleration in a static coordinate metric
ds^2 = gttdt^2 - grrdr^2 - r^2(spherical coordinate metric)
is
g(r) ~ gtt^-1/2d(g00/dr)
the two metrics of interest are
gtt = 1 - A^1/2/r black hole of area entropy A
we at r ---> infinity outside black hole
gtt = 1 - r'^2/A de Sitter horizon
we at r' = 0
inside cosmological horizon
use
1 + z = femit/fobserve f = frequency
1 + z = [gtt(observe)gtt(emit)]^1/2
http://en.wikipedia.org/wiki/Redshift
Quantum gravity says horizons gtt = 0 are really Lp thick.
so for both metrics above using
r = A^1/2 + Lp for black hole
&
r' = A^1/2 - Lp
get same factors (Lp/A^1/2)^1/2 redshift of radiation emitted from A
(A^1/2/Lp)^1/2 blue shift of radiation falling into A.
Now the Hawking black hole radiation temperature at A is
T ~ h(A^1/2/Lp)c^2/cA^1/2kB ~ hc/kB(LpA^1/2)^1/2
and this redshifts down to hc/A^1/2kB ~ Newtonian horizon surface gravity just as Hawking says.
In contrast, for the new quantum gravity radial oscillations of the thickness of the horizon
T' ~ hc/LpkB
which redshifts down to us to T' ~ hc/kB(LpA^1/2)^1/2
by Stephan Boltzman T^4 law
this gives hc/Lp^2A
both for anomalous w = +1/3 radiation from black holes whose horizon is not observer dependent
& also dark energy density from future horizon which looks like w = -1 virtual photon vacuum energy peaked at c/(LpA^1/2)^1/2 frequency whose horizon is observer dependent.
We need to use John Cramer's TI here.

We recede from our past particle horizon, but we approach our future event horizon.
Therefore, retarded radiation in our past light cone is cosmologically red shifted.
Advanced radiation in our past light cone is cosmologically blue shifted.
However, because the effective available space between us and our future horizon is contracting - even though space as a whole is speeding up in its expansion from the anti-gravity dark energy (virtual bosons w = -1), it follows that
Retarded radiation on our future light cone is blue shifted at our future horizon.
Advanced radiation from our future horizon to us at r = 0 is redshifted because it sees available space expanding backwards in time.
Also when you use the static LNIF representation
g00 = 1 - r^2/A
the gravity red shift of hc/Lp^4 Hawking radiation at r = A^1/2 - Lp is the observed dark energy density of hc/Lp^2A at the r = 0 detector.
This is the best of all possible explanations of the dark energy rooted in the Wheeler-Feynman idea.
OK, Jim here is the answer. We are getting closer to our future horizon in co-moving distance as cosmic time from the inflation -> hot big bang goes on.
Looking at Tamara Davis's causal diamond picture. Uncompensated advanced Wheeler-Feynman black body radiation back from our future horizon to us starts at a(then) ~ 8 billion light years
It reaches us at about
a(now) ~ 14 billion light years
~ 14/8 ~ 7/4 ~ 1.75 > 1
But this co-moving geodesic LIF cosmological redshift is still small compared to the much larger off-geodesic static LNIF gravity redshift of order
1 + z' ~ 10^123 >> 1
http://en.wikipedia.org/wiki/Redshift
So in that sense, the co-moving distance to the future horizon is contracting for retarded radiation from us to our future horizon - hence blue shift for it. The opposite for back from the future Hawking radiation from our future horizon to us - hence red shift for it.

If that is so Jack, what you have is a compelling argument against Hawking radiation, the advanced part anyway, having anything to do with our present. In the static LNIF rep

and with that metric, which only is in our future not in our past we get
hc/Lp^4 on the future horizon r = A^1/2 - Lp redshifts down to the observed dark energy density hc/Lp^2A
that is simple mathematics from
For the blue shifting of advanced radiation is a consequence ONLY of the fact that the radiation passes from expanded space to more compact space in transit, causing the wavelength of the radiation to decrease. It has nothing to do with the circumstances of emission.
In fact its just the opposite inside our causal diamond observable patch of the multiverse.
The electron-positron pairs stuck on our relative horizon have enormous proper accelerations c^2/Lp, the horizon is not expanding at all away from us, it's at fixed r = A^1/2 - Lp from us. It has nothing directly to do with expanding space in this conformal diagram. In fact, we are getting closer in co-moving distance to our future horizon whilst receding away from our past horizon.
The way you can salvage your argument is to claim that Hawking radiation (retarded) from our past cosmic horizon is redshifted and so on.
No, that does not work at all. Our past metric is nothing like de Sitter and hc/Lp^2A is way too big in the past because A is smaller!
A approaches a fixed asymptote (middle solid curve below)

1 + zadv = femit/fobs = anow/athen < 1 advanced co-moving LIF blue shift
Which was what you said.
The situation is different for static LNIF detectors in which the far future metric in de Sitter space for our accelerating dark energy universe is
ds^2 ~ -c^2(1 - r^2/A)dt^2 + (1 - r^2/A)^-1dr^2 + ...
we are at r = 0 and the proper acceleration of the detector at fixed r is
g(r) ~ g00^-1/2dg00/dr
g00 ~ 1 - r^2/A g(future horizon) -> infinity classically in fact it's large and finite c^2/Lp ~ 10^54 cm/sec^2 from the Planck cut off Now in fact the virtual electron positron pairs are stuck on this horizon relative to us at r = 0. They have plenty of energy from their local thermal bath of Unruh photons to become real pairs relative to us.
They will Hawking radiate advanced waves to us from r = A^-1/2 to us at r = 0 at their local temperature of
T = hg/ckB = hc/LpkB
Now use the time symmetric static LNIF redshift formula starting from r = A^1/2 - Lp emission to r = 0 US reception.

The redshifted result is
T' = hc/(LpA^1/2)^1/2
Using the Stefan Boltzmann law this is an energy density ~ T'^4, i.e. hc/Lp^2A exactly as observed for the dark energy density.
Since we at r = 0 have zero proper acceleration, we see this energy as w = -1 virtual photons of mean frequency c/(LpA^1/2)^1/2 rather than the w = + 1/3 real photons.
So we have TWO effects simultaneously.
Yes, there will I think be a small LIF blue shift correction to the much larger static LNIF advanced redshift.
1 + zadv = femit/fobs = anow/athen < 1 advanced co-moving LIF blue shift
However, anow/athen is of order unity, i.e. 46/55. You can see we are at about 46 billion light years from Alpha creation in Penrose conformal time. Our future light cone intersects our future event horizon at roughly 55 billion light years. We have to look at the de Sitter metric in conformal time and then do a calculation of the usual anow/athen. I need to check this more carefully of course. Right now I assumed that a(t) is linear in Penrose conformal time, but this may be mistaken.

On CCC-predicted concentric low-variance circles in the CMB sky

Abstract. A new analysis of the CMB, using WMAP data, supports earlier indications of non-Gaussian features of concentric circles of low temperature variance. Conformal cyclic cosmology (CCC) predicts such features from supermassive black-hole encounters in an aeon preceding our Big Bang. The significance of individual low-variance circles in the true data has been disputed; yet a recent independent analysis has confirmed CCC’s expectation that CMB circles have a non-Gaussian temperature distribution. Here we
examine concentric sets of low-variance circular rings in the WMAP data, finding a highly non-isotropic distribution. A new “sky-twist” procedure, directly analysing WMAP data, without appeal to simulations, shows that the prevalence of these concentric sets depends on the rings being circular, rather than even slightly elliptical, numbers dropping off dramatically with increasing ellipticity. This is consistent with CCC’s expectations; so also is the crucial fact that whereas some of the rings’ radii are found to reach around
15◦, none exceed 20◦. The non-isotropic distribution of the concentric sets may be linked to previously known anomalous and non-Gaussian CMB features.

Title: Dark Energy as Redshifted Advanced Wheeler-Feynman Hawking-
Unruh Thermal Radiation
Abstract content
The observed anti-gravity repulsive dark energy density hc/Lp^2A where A is the area of our observer detector dependent de Sitter future event horizon at its intersection with the detector's future light cone is proved to be the cosmological redshift of the quantum field theoretic energy density hc/Lp^4 on that horizon. The effective redshifted Hawking-Unruh temperature at our detectors is hc/kBLp^1/2A^1/4. The real thermal advanced photons from our future horizon are maximally redshifted down to virtual photons of energy hc/Lp^1/2A^1/4. The calculation may be extended to include ordinary retarded photon signals in our detector's past light cone from Type 1a supernovae because the area A of the future horizon has an asymptote. Larger redshifts should show the cosmic time dependence of A as a test of this model. I suggest that gravity attractive dark matter is a vacuum polarization effect. Therefore, real on-shell exotic dark matter particles do not exist as a matter of principle.
Summary
The observed dark energy density hc/Lp^2A where A is the area of our observer detector dependent de Sitter future event horizon at its intersection with the detector's future light cone is computed from elementary battle-tested physics. In addition, it is predicted that real dark matter particles do not exist as a matter of fundamental principle. Dark matter is a vacuum polarization effect.

Light hadron masses from lattice QCD
Reviews of Modern Physics – April - June 2012 Volume 84, Issue 2
•
Zoltan Fodor and Christian Hoelbling
One of the most basic tests of quantum chromodynamics in the strong coupling regime is whether it can successfully predict the spectrum of light hadron masses in terms of a small number of inputs. This article surveys the status of lattice calculations of the spectrum, including the formalism, theoretical uncertainties, and current results. The calculations successfully reproduce relevant parts of the observed spectrum at the percent level.

So who needs Mach’s Principle for the origin of inertia?
Bearing in mind Basil Hiley’s remark:
To build in wholeness in this preliminary way, we stressed in the UU that the "particle and the field were never separate". Here we were motivated by the work of Frederick Frank at Bristol and Bilby and his co-workers at Sheffield. They had been exploring the geometry of continuous dislocations in crystals and had shown that the equation of migration of dislocation was similar to a relativistic particle dynamics which involved the speed of sound rather than the speed of light. Furthermore the stress forces in the lattice had a similar form to electromagnetic fields. Notice you can't separate the particle from the field: no lattice, no particle implies no field, no particle. We do not give any meaning to the statement that 'the particle is in one of the wave packets'. That is, questions about "empty wave packets" has no meaning in the structure we had in mind.

Gaussian quantum information
Christian Weedbrook, Stefano Pirandola, Raúl García-Patrón, Nicolas J. Cerf, Timothy C. Ralph, Jeffrey H. Shapiro, and Seth Lloyd
Quantum information processing and communication protocols are typically expressed in terms of discrete units of information, the quantum bits (or qubits). However, certain experimental setups involving, for instance, light or atomic ensembles, are based on continuous quantum system and, in particular, on Gaussian states and operations. This review adapts the main ideas and protocols in the field of quantum information to such systems, and explains their advantages and limitations.

Theoretical aspects of massive gravity
Kurt Hinterbichler
The discovery that the expansion rate of the Universe is accelerating, perhaps due to a nonzero and very small cosmological constant, has led to many speculations regarding modifications to the long distance structure of general relativity. This review discusses modifications which generate a mass for the graviton from a theoretical point of view and includes a treatment of diffeomorphism invariance, interactions, and the low-energy effective field theory treatment of such theories.

Dual pairing of symmetry and dynamical groups in physics
D. J. Rowe, M. J. Carvalho, and J. Repka
Symmetries, group theory, and the related theory of Lie algebras underlie quantum mechanics and provide the essential language for the interpretation of physical phenomena. This review discusses foundations and applications of dual representations of pairs of symmetry and dynamical groups primarily in atomic and nuclear physics, especially in the context of bosonic and fermionic many-body systems such as superconductors, molecules, and nuclei. By studying such dual subgroup chains, associations of phenomenological many-body models with microscopic approaches are revealed.

Colloquium: Supersolids: What and where are they?
Massimo Boninsegni and Nikolay V. Prokof’ev
Supersolid is the name of an exotic quantum phase of matter, combining the seemingly antithetical properties of crystal and superfluid phases. This phase is expected to exist in rather extreme circumstances, for example, in solid helium near absolute zero. Indeed, claims of its experimental observation have been made. This Colloquium reviews the bulk of the existing phenomenology and offers an interpretation of it, based on theoretical results of first principle computer simulations. Other physical systems in which the supersolid phase might be observed in the laboratory are also described.

Multiphoton entanglement and interferometry
Jian-Wei Pan, Zeng-Bing Chen, Chao-Yang Lu, Harald Weinfurter, Anton Zeilinger, and Marek Żukowski
Light is made out of photons, which now can be efficiently created, manipulated, and detected. This provides us with the possibility of testing several fundamental aspects of quantum mechanics, ranging from the quantization of energy to the superposition principle, or the violation of Bell inequalities. Also, the degree of control that has been achieved over the properties of the photons has opened up a broad spectrum of applications in the context of quantum information science. This review provides an introduction to multiphoton systems, with an emphasis on their entanglement properties. It also contains an exposition of the fundamental tests that have been carried so far with such systems, as well as the key experiments on quantum communication and computation.

How higher-spin gravity surpasses the spin-two barrier
Xavier Bekaert, Nicolas Boulanger, and Per A. Sundell
Gauge theories mediate forces through particle of spin one while the gravitational force is mediated through particles of spin two. It has long been thought that there are no consistent theories with fundamental particles of spin greater than 2, but recent constructions show that while this standard lore is probably true in flat spacetimes, spaces with constant curvature that occur in the presence of a cosmological constant provide a loophole that allows construction of consistent higher-spin generalizations of gravity. This review explains the original no-go results in flat space and then discusses the construction of higher-spin theories in backgrounds with a cosmological constant.

In my gauge theory of gravity, the basic LIF tetrads are compensating spin 1 vector fields from localizing the universal space-time symmetry group for all matter fields. Einstein’s spin 2 gravity would be something analogous to a Cooper pair, i.e. an entangled triplet of a pair of spin 1 quanta with S-state orbital. Of course “graviton" higher spin states with P, D ... orbitals are conceivable. Of course a Cooper pair of spin 1/2 electrons are bound by spin 0 phonons - what binds the gravity tetrads into a pair?

Very much appreciated your online explanation that the Higgs field is made up of virtual Higgs Bosons, and that you have to "hit" the vacuum with 100s of GeV energy to materialize a Higgs in real space.
If the Higgs field is the source of inertial mass, and gravitation mass is equal to inertial mass from the equivalence principle, then is the Higgs field also the source of gravity? I think this would require the Higgs field "viscosity to become anisotropic, making easer for a particle to accelerate towards a mass then away from one.

Physicists Propose Building a Crystal of Space-Time

One of the simplest and most common physical objects is your average crystal, a collection of atoms arranged in an orderly, repeating three-dimensional pattern. Salt, snowflakes, and the quartz in your watch are all crystals. Earlier this year, the Nobel laureate and MIT physicist Frank Wilczek prop...

There is a very intuitive though not simple way to understand the space-time crystal.
1) spontaneous broken symmetry in complex many particle systems. These are quantum phase transitions like when our observable universe is created in the moment of inflation out of the pre-existing unstable false vacuum in which all particles have zero rest mass because the Higgs field had not yet formed. The appearance of the Higgs field is the effect spontaneous broken symmetry in which the post-inflation quantum vacuum of our expanding universe. The quantum vacuum has less symmetry than do the field equations for some of the matter fields.
2) Quantum field theory shows that matter exists in two very different forms - real and virtual. Matter in virtual form lives inside the quantum vacuum briefly popping into and out of existence. We see this indirectly in small shifts of spectral lines of atoms (Lamb shift) and in the Casimir zero point force between two neutral plates. Virtual particles do not transport energy outside the "near field" and they cannot directly cause a counter to click only real particles can do that. The LHC just showed us a real Higgs boson kicked out of the vacuum by the tremendous focused energy of the machine. It's like chipping a small piece of ice out of a huge glacier that is the VIRTUAL Higgs-Goldstone spontaneous broken symmetry field inside the vacuum. There are two kinds of spontaneous broken symmetry particles. The Goldstone particle has zero rest mass like the photon particle of light. The Higgs particle has a finite rest mass now seen at about 125 Gev in the LHC. There may be several Higgs and Goldstone particles. The Higgs and Goldstone particles come in conjugate pairs like the amplitude and phase of a coherent laser beam wave. In fact the Higgs-Goldstone vacuum field is mathematically somewhat similar to a laser beam field with some important differences of course. The mathematics of these general "coherent states" was worked out in the early 1960's by Nobel Laureate Harvard physics professor Roy Glauber. Basically we have a large number of particles all in the same single-particle quantum state although that actual number is uncertain and in the simplest case has a Poisson distribution.This happens not only in lasers but in superconductors and as we see below even in Frank Wilczek's space-time crystal. The difference is that the Higgs vacuum field that itself gives rest masses to the leptons and quarks is made up of huge numbers of VIRTUAL Higgs-Goldstone conjugate particle pairs that form a set of complex numbers z in the polar representation for those of you who know some high school math where z = Rexp(itheta). R is the amplitude and theta is the phase. The massive Higgs particle in real form are quantized vibrations in the amplitude R like you AM radio. The massless Goldstone particles in real form are quantized vibrations in the phase theta of the coherent vacuum field like your FM radio roughly.
3) A space crystal is a periodic lattice of atoms that forms in a quantum phase transition in which the continuous translational symmetry of the higher temperature gas or liquid is spontaneously broken down to a much smaller discrete crystal group. The phonon is a massless Goldstone particle. The analogous Higgs particle would be a phonon sound wave with an energy gap at infinite wavelength. However, a single phonon is a collective normal mode of all the real atoms that form the crystal lattice. Now real phonons that propagate sound energy have a frequency that is the speed of sound divided by the wavelength. However, virtual phonons do not obey that relationship at all. Indeed, the crystal lattice itself is a Glauber coherent state of a huge uncertain number of VIRTUAL PHONONS all in the same single-phonon quantum state. These particular virtual phonons have zero frequency with finite wavelengths along the three directions of space that are determined by the particular discrete space-crystal group that is not spontaneously broken. A very similar thing happens for electromagnetic photons in the ordinary electrostatic Coulomb field e/r potential energy per unit test charge q in the rest frame of a point charge e where r is the distance between e and q. The longitudinal electrostatic field is a coherent Glauber state of a huge uncertain number of virtual photons of zero frequency with a whole continuum of wavelengths along the three dimensions of space.
4) We now have a unified conceptual framework. The space-time crystal is simply a Glauber coherent state of again virtual phonons but this time with a finite frequency and the same set of discrete wavelengths as in the space-crystal.
