Which way does NASA Pioneer 10 & 11 anomaly point?

Nature 30 Sept 2004 p. 494 and New Scientist 19 March 2005 p. 35 disagree. Nature says the force points back to the Sun, New Scientists says it points away from the Sun. One paper cites an anomalous blue shift, which seems consistent with Nature's account and not New Scientist's.

Hi I have been in LA at Paul Harris's Time & Wonder Seminar at Loyola and need to catch up with e-mails. I literally just rolled in - been driving all day.

1. Reg where can I see a detailed derivation of your key n(n^2 - 1) equation from special relativity upon which your key claim rests?

2. Which way does the Pioneer Anomaly point, radially in or out? New Scientist in 13 things that don't make sense, March 19 - 25 says it's a repulsion of one nanometer per second per second. So I may have had it pointing wrong way in my earlier remarks. I need to check the original papers. Does anyone know for sure? Neither, Carlos nor Tony, nor Creon caught me on that error, if it is one? In any case I can model it as a hedgehog defect either way.

If it points out then /\zpf < 0 i.e. positive pressure. If it points in then /\zpf > 0 negative pressure.

In either case

|/\zpf| = H(t)/cr for r > 20 AU

r = radial distance to Sun

The Poisson eq. Green's function is 1/r, the volume element is r^2dr

Therefore, the integral for the gravity potential energy per unit test particle of the exotic vacuum is approximately

V(zpf) ~ c^2/\zpfr^2 ~ cHr = cv

v = Hubble velocity of recession from the expansion of space R(t) in FLRW even at 20AU!

a_g = - dV(zpf)/dr ~ cH ~ 1 nanometer per second per second pointing either way depending on sign of /\zpf.

Think of dropping a ball through hole drilled through center of the Earth.

3. Note for the Galactic dark matter halo, also an exotic vacuum effect

/\zpf = (v/c)1/r^2

V(zpf) ~ cv

a_g = 0

here v is the constant circulating speed of a star in flat part of the stellar rotation curve.

4. What about ultra-energetic cosmic rays above the GZK limit = 5x10^19 ev? Some kind of anti-gravity dark energy acceleration?

5. The little black holes - a triumph for string theory at last and for Hawking radiation?

Ben Varcoe in the UK is setting up just such a Bose-Einstein experiment. However the problem is that no one knows how the refractive indices in the two orthogonal directions changes under rotation in such a system. In a gas we know they are uncorrelated. But in a transparent solid they are related, as one would expect. As well the problem with the Michelson interferometer is that it is a 2nd order device..the fringe shifts vary as (v/c)^2. Then various effects all compete: geometrical effects, length contractions, Fresnel drag, correlated refractive index effects,.. This is why we are setting up a coaxial cable experiment. The time variations are first order in v/c, and so relativistic effects are not important, there are no moving parts, and the effect is easily computer recorded. As well we can record in three orthogonal directions, which means a component of the absolute motion velocity in the vertical direction. No one has ever operated a Michelson interferometer in a vertical plane. The need for this vertical measurement is that we need to determine the in-flow component associated with the earth's gravity. This has a speed of 11km/s at the earth's surface. The inflow towards the sun has already been extracted from the Miller data..that speed is some 42 km/s.

Well clearly the logical foundations of special relativity need to be reexamined in case these data prove plausible & compelling. Suppose Lorentz was really right that length contractions and time dilations need to be referred directly to the Eve frame of absolute rest. Is there a way of seeing that directly in the rest frame of a uniformly moving nano-structure (uniformly moving relative to Eve frame)? After all, your alleged effect is a rest frame effect for the interferometer. The only frame in which your alleged shift would not be seen would be the Eve frame. Also, is the Eve frame, if it were to exist a spontaneous broken vacuum symmetry in the rapidity boost piece of O(1,3) just as a finite domain of a ferromagnet picks a preferred space direction for O(3) in the ground state even though the O(3) symmetry is still intact in the dynamical action and the local laws of nature?

What about doing experiments with really large indices of refraction n to see the alleged n(n^2 - 1) effect? Perhaps a gas atomic Bose-Einstein condensate with n >> 1 in some kind of laser pulse experiment?

It is not possible to determined the size of the effect that one would expect in this experiment because the two experimentalists didn't understand how the apparatus worked. To determine the size of the effect we now understand that one needs to know the refractive index of the He-Ne gas mixture. This is not given. However from the work of Jaseja et al Phys. Rev. A133(1964)1221 I could determine in that case that their He-Ne gas mixture had a refractive index of approx n=1.0000028, and so is very close to being a vacuum. So it appears that this experiment was essentially a vacuum experiment. Hils and Hall also used the wrong theory to analyse any signal, namely the Robertson, Mansouri and Sexl formalism.

This formalism is predicated on a spacetime ontology, and also makes no allowance for the effect of any gas present. The key point to appreciate is that until 2002 no one understood how one could and should measure absolute motion. So some techniques were lucky, ie they had the necessary technique, while others were unlucky. Miller, DeWitte and some 5 others were lucky experiments. This Hils and Hall experiment was an unlucky simply was blind to the incredibly small effects of absolute motion. However being essentially a vacuum experiment one aspect of the physics that it did check was Lorentz symmetry. Remember that we also now understand that Lorentz symmetry and absolute motion are compatible properties of space, indeed absolute motion is the dynamical cause of the Lorentz symmetry effects. The detection of absolute motion is not a return to Newtonian physics, but it does invalidate Einstein's postulate about the invariance of the speed of light. We now understand, as of 2002, that this postulate was always in disagreement with experiment. What is emerging as the correct theory is essentially a neo-Lorentzian relativity, which predated Einstein's 1905 work. Then it is possible, for example, to write Maxwell's equations in a form that clearly separates the various physics involved. The original and usual covariant form of Maxwell's equations actually melds two different phenomena in such a way that neither is now clearly revealed. The major development is that the whole spacetime ontology, both flat and curved, was a house of cards, held up mainly by misunderstandings. It has now crumbled.



I just realized that Hils and Hall's experiment is a direct test of your theory.

They used a laser mode-locked to a vacuum Fabry-Perot cavity interfering
with a single-mode He-Ne laser locked to an I_2 line, both fixed in the lab. They looked for sidereal variations in the beat frequency. As one laser's frequency is determined in vacuum, and one in gas, this seems to me to be a direct test of your theory.

Hils and Hall, Phys. Rev. Lett. 64 (1990), p 1697.

They found no variations at the level of 2*10^-13. I think your theory is in deep trouble here....
