“We may regard the present state of the universe as the effect of its past and the cause of its

future. An intellect which at any given moment knew all of the forces that animate nature and the

mutual positions of the beings that compose it, if this intellect were vast enough to submit the

data to analysis, could condense into a single formula the movement of the greatest bodies of the

universe and that of the lightest atom; for such an intellect nothing could be uncertain and the

future just like the past would be present before its eyes." Newton

 

In contrast, today we think that we may regard the present state of the universe as the effect of both its past and its future in a Novikov loop in time. Our future 2D event horizon hologram 't Hooft cellular automaton may be a conscious super-computer in which all past events are its 3D hologram images - a really crazy idea of course. Is it crazy enough to be true?

THE IMPLICATIONS OF A COSMOLOGICAL INFORMATION BOUND FOR COMPLEXITY, QUANTUM INFORMATION AND THE NATURE OF PHYSICAL LAW

"The finite age of the universe and the existence of cosmological horizons provides a strong argument that the observable universe represents a finite causal region with finite material and informational resources. A similar conclusion follows from the holographic principle. In this paper I address the question of whether the cosmological information bound has implications for fundamental physics. Orthodox physics is based on Platonism: the laws are treated as infinitely precise, perfect, immutable mathematical relationships
that transcend the physical universe and remain totally unchanged by physical processes, however extreme. If instead the laws of physics are regarded as akin to computer software, with the physical universe as the corresponding hardware, then the finite computational capacity of the universe imposes a fundamental limit on the precision of the laws and the specifiability of physical states. That limit depends on the age of the universe. I examine how the imprecision of the laws impacts on the evolution of highly entangled states and on the problem of dark energy."

See Tamara Davis's Figs 1.1 & 5.1 2004 PhD online University New South Wales

Quite trivially:

Unruh-Hawking temperature at the horizon is 1/(area)^1/2

dark energy density is 1/(area) ~ 10^-7 ergs/cc

h = c = kB = G = 1

Any school boy can now understand why the entropy of the early universe is small by 10^123 from its future constant value, and why we age as the universe speeds up in its expansion causing our observer-dependent horizon that is also the Wheeler-Feynman total absorber of last resort.

When a photon is absorbed it disappears - effectively f = 0, well that's what happens to photons we emit because their wavelength gets stretched by the expanding space and the stretch is infinite at the finite co-moving distance to our future horizon that bounces back the advanced return signal to make the Cramer transaction.

Professor M. Stoneham pointed out that in a dispersive medium there are three "c" s, phase speed, group speed, signal speed. Which one should we use in G/c^4?

I have used c' = c/n

n = index of refraction

so that would normally be phase speed. 

group speed is df/dk

phase speed is f/k

signal speed is more tricky.

Also here, and here.

Subject: Re: Strange properties of superconducting meta-material - propellantless propulsion engine concept

Dear James
No, that's not what I have in mind at all - just the opposite.
I think nano-engineered high Tc metamaterial are very likely, and indeed, that's how the real ET spacecraft fly.
I could wrong of course.
Also, my point is LOW  negative energy density interstitial EM fields - their bending effect on spacetime geometry is amplified by the fourth power of the dispersive index of refraction i.e. n^4G/c^4.
Jupiter mass stuff is not correct in my opinion. It it were ET craft would not be possible yet they are here - that's the scenario I am assuming in this war game.

i.e. Guv + (n^4G/c^4)Tuv(EM) = 0

n ~ -10^10

f(permitivity)E^2 +g(permeability)B^2  < 0 

for non-radiative interstitial near induction fields (coherent states of virtual photons)

Suppose we could make a very high Tc superconducting meta-material.

The effective speed of light is then c/n where n < 0 and |n| >> 1. 
Of course there will be dispersion, i.e. n(k,w) including virtual 
photons.

Let's be naive and look what happens to the Planck units.

LP* = (hGn^3/c^3)^1/2 >> LP ~ 10^-33 cm

TP* = LP*/c = (hGn^5/c^5)^1/2 >> TP ~ 10^-43sec

P*P = h/LP = h/(hGn^3/c^3)^1/2 << PP

does the "i" have any physical meaning?

The Planck energy is 

EP* = (hc^5/n^5G)^1/2 << EP ~ 10^19 Gev

again all of these parameters get an i

The Action Cartan 1-form is 

S = Et - Px ---> -S

So the Feynman amplitudes go to their complex conjugates.

The gravity coupling of matter to curvature is now n^4G/c^4 = 
1/G-string tension

suppose n ~ 10^10

LP* ~ 10^-18 cm

TP* ~ 10^-18 sec

EP* ~ 10^-6 Gev = 1kev

Furthermore the classical coherent electromagnetic field energy 
density is negative - for classical fields this should produce 
antigravity for non-radiative near fields (coherent states of 
virtual photons) trapped inside the superconducting meta-material as 
confined quantized magnetic vortices (Abrikosov lattice) under Type 
II conditions.

The coupling of these magnetic vortices to the geometrodynamic field 
will be 10^40 times stronger than normal.

This amazing material in my imagination at the moment would also 
have stealth cloaking functionality.

Dynamical quantum non-locality

Sandu Popescu1

This is an important article - here are some excerpts:

"That nature is non-local, in the sense of so-called Bell-inequality violations, is by now well known. That is, quantum physics allows correlations between distant particles that are stronger than allowed classically: for classical systems to show such correlations they would need to communicate faster than light. Understanding this kind of non-locality and using it is one of the greatest achievements of quantum information science. The non-locality discovered in the AB effect, however, is completely different. Bell-inequality violations follow from the Hilbert-space structure of quantum mechanics; they are purely kinematic. On the other hand, the AB type of non-locality is dynamic — it is the non-locality of the quantum equations of motion."

How quantum wave interference is qualitatively different from classical wave interference:

"Let us first consider waves on water, with the two-slit screen being a dam with two openings in front of the beach. Two observers on the dam, one next to each opening, could both observe and record the phase of the wave, by simply measuring how high the water is as a function of time. They could then find the relative phase by calculating the difference of the phases. So not only can the relative phase be observed, but the individual phases as well.

On the other hand, quantum mechanically α1 and α2 cannot be observed. Indeed, quantum mechanically an overall phase is unobservable."

Enter quantum dynamical nonlocality in the relative phase shift operator:

"We thus arrive at a first significant conclusion: the information about the interference is contained in the average of the shift operator, not in the averages of any power of position or momentum. It is therefore this operator that is the relevant one. Without a better understanding of its properties we have no way of actually understanding quantum interference.

New dynamics ahead?

To summarize, quantum interference is not the benign phenomenon that it is generally considered to be. It is fundamentally different from classical interference. The relevant observables are non-local and they obey non-local equations of motion.

...

The implications are dramatic. On the one hand, the analysis described here sheds new light on the mystery of interference, to the extent that it should change the whole discourse. Rather than focusing on what happens at the screen — wavefunction collapse and so on — one should go back and revisit the notion that an electron, while passing through one slit, cannot know what happens to the slit not taken. It certainly can know, if the physics is non-local. But the implications do not stop here, at the subject of 'interpretations of quantum mechanics'. It is much more than that.

The entire quantum evolution is subject to dynamical non-locality, so we should be able to see its consequences in various quantum effects, regardless of their interpretation. ...

Conceptually however we are almost there. That non-local interactions exist and do not conflict with causality is only possible under the umbrella of quantum uncertainties. This, if we turn the table around, may give a whole new meaning to the reasons that uncertainties exist in the first place — so that nature may be non-local."

Popescu's theory is consistent with Bohm's ontological theory. The former may be easier to make special relativistic than the latter.

Fly in the dark energy ointment?

Posted by: JackSarfatti |
Tagged in: Untagged 

Standard candle' flickers too brightly

"An international team of researchers has measured the mass of a distant exploding star system – and found that it weighs considerably more than the accepted mass limit for such bodies. As these type 1a supernovae are widely used as "standard candles" to measure distances in the universe, the finding could have important consequences in cosmology, particularly concerning theories of dark energy. ... Even though Scalzo's result indicates that not all type 1a supernovae are as neat and tidy as previously thought, dark energy is probably still safe, because there is still further evidence that it exists. "There is other observational evidence from the cosmic microwave background and galaxy surveys. Take any one of these away and dark energy still exists," says Malcolm Fairbairn, a particle astrophysicist at King's College London, who was not involved in the research. "However, it has been very worrying that we rely on type 1a supernovae as standard candles but we don't really know exactly what they are," he adds."

The trickiness of deSitter spacetime

From Bohr's Quantum to Future Horizon Hologram Computer Screen Complementarity
"The Question is: What is The Question?" 
"IT FROM BIT"
J. A. Wheeler from Bohr's to Horizon Hologram Computer Screen Complementarity
From Wickedpedia below, but not as above:
Where we are at r = 0 - the frequency shift formula here is

dt = invariant

therefore,

ds(0)/goo(0)^1/2 = ds(r)/g00(r)^1/2

frequency = 1/ds

1/f(0)goo(0)^1/2 = 1/f(r)g00(r)^1/2

f(r)/f(0) = [goo(0)/goo(r)]^1/2 ---> (1 - / ^2/3)^-1/2 ---> infinity at our future horizon

This is an infinite blue shift for the static LNIF at our future horizon where 1 - / ^2/3 = 0 detecting light signal from us at r = 0 along its past light cone that connects with our future light cone. Similarly the advanced wave back from our future will be infinitely redshifted. However, there is complete cancellation in the Cramer transaction, the return wave in the Novikov loop is always the same frequency as the offer wave no matter what set of observer-participators do the measurements. Each set will have a consistent description - though not the same description.

This is in contrast to us outside a black hole where we as static LNIF are at r ---> infinity

f(r)/f(infinity) = (1 - 2GM/c^2r)^-1/2 ---> infinity at the horizon, i.e. we see zero frequency at r = infinity, i.e.  infinite red shift for a retarded wave coming from the black hole horizon along our past light cone.
There are other sets of observers - not all of them are physically interesting. The math allows more choices than are physically convenient. Note that Wickedpedia does not use the conformal observers that Hoyle and Narlikar use here in 4)

4) Note the issue of the red and blue shifts is very tricky depending on the state of acceleration of the absorber detectors.
The cosmological red shift z is, for the de Sitter (dS) metric relative to us at proper time zero
1 + z = (wavelength at co-moving absorber)/(wavelength at comoving emitter) = e^/(proper time at absorber) ---> infinity at our future horizon.
To see the connection with the conformal time diagram Fig 1.1
Conformal time tau = /^-1/2[1 - e^-/^1/2proper time)]
infinite proper time at our future horizon is finite conformal time 
tau = /^-1/2
The conformally flat dS metric is
ds^2 = (1 - /^1/2tau)^-1[Minkowski metric]
---> infinity at the future event horizon consistent with zero frequency.
This is for co-moving observers in the accelerating Hubble expansion flow.
Static LNIF observers see something entirely different at fixed r where
g00 = 1 - / ^2 = -1/grr
static LNIFs see an infinite blue shift of light coming at r = 0 as they adiabatically approach r --- /^-1/2
indeed, their real tensor covariant acceleration ~ Unruh temperature needed to stay at fixed r is
g(r) = 2c^2/ (1 - / ^2)^-1/2 ---> infinity at the future horizon.
This is an example of horizon complementarity - one has to specify precisely the total experimental arrangement to get sensible answers not only in quantum theory, but also in Einstein's theory of curved space-time gravity.

I conjecture (not in Tamara's PhD) that on our observer-dependent future horizon:
1) Our future horizon is the hologram computer screen and it is the Wheeler-Feynman total absorber.
2) All matter field fibers in the 3D + 1 bulk including the gravity field inside our future horizon - a closed surrounding non-bounding 2D surface enclosing topological geometrodynamical field monopole singularities - one per pixel on the future horizon - are retro-causal hologram image projections back from our future horizon. 
3) The quantum field theory or, perhaps, string theory on the horizon hologram is generally non-Abelian anyonic.
4) Note the issue of the red and blue shifts is very tricky depending on the state of acceleration of the absorber detectors.
The cosmological red shift z is, for the de Sitter (dS) metric relative to us at proper time zero
1 + z = (wavelength at co-moving absorber)/(wavelength at comoving emitter) = e^/(proper time at absorber) ---> infinity at our future horizon.
To see the connection with the conformal time diagram Fig 1.1
Conformal time tau = /^-1/2[1 - e^-/^1/2proper time)]
infinite proper time at our future horizon is finite conformal time 
tau = /^-1/2
The conformally flat dS metric is
ds^2 = (1 - /^1/2tau)^-1[Minkowski metric]
---> infinity at the future event horizon consistent with zero frequency.
This is for co-moving observers in the accelerating Hubble expansion flow.

g00 = 1 - / ^2 = -1/grr

This is not an April Fool joke, though perhaps I am mistaken.
