The correct analysis and explanation of the Pioneer-Galileo anomalies
Tidal distension of spacecraft electronics due to spin and solar and galactic
gravitation elegantly explains all variations in the anomaly reported by
Anderson et al. Contrary to their conclusion, a constant residue seems to be
present in lunar, terrestrial, and possibly planetary measurements, posing a
problem of wider, more fundamental significance.Comment: 6 pages, 4 figures, calculation error correcte
Entanglement, thermalisation and stationarity: The computational foundations of quantum mechanics
'Tis said, to know others is to be learned, to know oneself, wise - I
demonstrate that it could be more fundamental than knowing the rest of nature,
by applying classical computational principles and engineering hindsight to
derive and explain quantum entanglement, state space formalism and the
statistical nature of quantum mechanics. I show that an entangled photon pair
is literally no more than a 1-bit hologram, that the quantum state formalism is
completely derivable from general considerations of representation of physical
information, and that both the probabilistic aspects of quantum theory and the
constancy of h are exactly predicted by the thermodynamics of representation,
without precluding a fundamental, relative difference in spatial scale between
non-colocated observers, leading to logical foundations of relativity and
cosmology that show the current thinking in that field to be simplistic and
erroneous.Comment: 10 page
A wave effect enabling universal frequency scaling, monostatic passive radar, incoherent aperture synthesis, and general immunity to jamming and interference
A fundamental Doppler-like but asymmetric wave effect that shifts received
signals in frequency in proportion to their respective source distances, was
recently described as means for a whole new generation of communication
technology using angle and distance, potentially replacing TDM, FDM or CDMA,
for multiplexing. It is equivalent to wave packet compression by scaling of
time at the receiver, converting path-dependent phase into distance-dependent
shifts, and can multiply the capacity of physical channels. The effect was
hitherto unsuspected in physics, appears to be responsible for both the
cosmological acceleration and the Pioneer 10/11 anomaly, and is exhibited in
audio data. This paper discusses how it may be exploited for instant, passive
ranging of signal sources, for verification, rescue and navigation; incoherent
aperture synthesis for smaller, yet more accurate radars; universal immunity to
jamming or interference; and precision frequency scaling of radiant energy in
general.Comment: Unclassified paper presented in IEEE MILCOM 2005 classified session.
This early paper discussed the basics of time-varying diffraction and
sampling, and their equivalence. A more rigorous treatment is given in

Relativity of spatial scale and of the Hubble flow: The logical foundations of relativity and cosmology
Formalising the logical dependence of physical quantities on material
referents of scale, I show that both Hubble's law and the cosmological constant
are in fact exactly replicable by a spatial contraction of referents locally on
earth, and that the Pioneer anomaly is irrefutable indication that this is the
case. The formalism literally embodies Feynman's ``hot-plate'' model,
predictably yielding a logical derivation of the relativity postulates, and
importantly, suffices to demonstrate the inherent logical consistency of
general relativity and quantum mechanics, whose foundations I have shown
separately to be fundamentally computational. I further show that the spatial
contraction of our referents also accounts for considerable planetary and
geological data inexplicable in the standard model, and predicts that the
Hubble flow appears differently or is altogether absent from platforms in deep
space, depending on the local physics.Comment: 8 page
Contraction and distension by tidal stress and its role as the cause of the Hubble redshift
I show that a cumulative contraction or expansion must result from repetitive
tidal action in a curved stress field, depending on the direction of the
curvature. The resulting expansion of solid materials onboard deep space probes
and the corresponding contraction on earth would be of the right magnitude to
account for all aspects of the Pioneer anomaly, leading to the two component
model previously proposed. Importantly, I show via signal path analysis that
the anomaly mathematically implies planetary Hubble flow, and that it is
predicted by the standard model equations when the cosmological constant is
also taken into account at this range. Also shown is that the variations of the
anomaly do not permit a different explanation. The prediction of the Hubble
flow occurring as a result in the view of the shrinking observer is now fully
explained from both quantum and Doppler perspectives, fundamentally challenging
the cosmological ideas of the past century. Lastly, I discuss how the
contraction reconciles the geological evidence of a past expansion of the
earth.Comment: 9 pages, 4 figs. Fig 1 ack adde
h is classical
Regardless of number, standing wave modes are by definition noninteracting,
and therefore cannot thermalize by themselves. Doppler shifts due to thermal
motions of cavity walls provide necessary mixing, but also preserve the
amplitudes and phases. The lambda/2 intervals of the modes thus preserved must
have equal energy expectations, say , in the resulting equilibrium. By
definition again, they can be exchanged between modes only in whole numbers and
hence only between harmonics. Each family of harmonic modes is thus
self-contained and is disjoint from other families in such exchanges, and
further, can have no more than one mode excited at any instant. The second
property identifies harmonic families of standing wave modes as the harmonic
oscillators of Planck's theory, since a family can only bear energy equal to
exactly one of E, 2E, 3E, etc These two properties further imply that the
energy expectation gets averaged only over an individual family, as the
equilibrium energy steadily available at a given mode would have
contributions from its entire harmonic family. Planck's equations reemerge, and
radiation quantization arises as a classical rule = f, as a mode must
contain a whole number of exchangeable lambda/2 intervals, but it only concerns
equilibrium states. The result makes Planck constant h an analogue of
Boltzmann's constant k for the frequency domain, and points to postulate-free
explanations of all aspects of quantum and kinetic theories.Comment: 10 pages, 3 figure
Observational evidence for travelling wave modes bearing distance proportional shifts
Discrepancies of range between the Space Surveillance Network radars and the
Deep Space Network in tracking the 1998 earth flyby of NEAR, and between ESA's
Doppler and range data in Rosetta's 2009 flyby, reveal a consistent excess
delay, or lag, equal to instantaneous one-way travel time in the telemetry
signals. These lags readily explain all details of the flyby anomaly, and are
shown to be symptoms of chirp d'Alembertian travelling wave solutions, relating
to traditional sinusoidal waves by a rotation of the spectral decomposition due
to the clock acceleration caused by the Doppler rates during the flybys. The
lags thus relate to special relativity, but yield distance proportional shifts
like those of cosmology at short range.Comment: 6 pages, 4 figure
Two theorems of Jhon Bell and Communication Complexity
John Bell taught us that quantum mechanics can not be reproduced by
non-contextual and local Hidden variable theory. The impossibility of replacing
quantum mechanics by non-contextual Hidden Variable Theory can be turned to a
impossible coloring pseudo-telepathy game to be played by two distant players.
The game can not be won without communication in the classical world. But if
the players share entangled state (quantum correlation) the game can be won
deterministically using no communication. This again shows that though quantum
correlation can not be used for communication, two parties can not simulate
quantum correlation without classical communication. The motivation of the
article is to present the earlier works on Hidden Variable Theory and recently
developed pseudo-telepathy problem in a simpler way, which may be helpful for
the beginners in this area.Comment: 11 pages, Invited lecture at the workshop on Quantum

GHZ correlation provides secure Anonymous Veto Protocol
Anonymous Veto (AV) and Dining cryptographers (DC) are two basic primitives
for the cryptographic problems where the main aim is to hide the identity of
the senders of the messages. These can be achieved by classical methods where
the security is based either on computational hardness or on shared private
keys. In this regard, we present a secure quantum protocol for both DC and AV
by exploiting the GHZ correlations. We first solve a generalized version of the
DC problem with the help of multiparty GHZ state. This allow us to provide a
secure quantum protocol for the AV. Securities for both the protocols rely on
some novel and fundamental features of GHZ correlations related to quantum
nonlocality.Comment: 5 pages, In this version we provide detail security proof of our
quantum protocol
Several foundational and information theoretic implications of Bell's theorem
In 1935, Albert Einstein and two colleagues, Boris Podolsky and Nathan Rosen
(EPR) developed a thought experiment to demonstrate what they felt was a lack
of completeness in quantum mechanics. EPR also postulated the existence of more
fundamental theory where physical reality of any system would be completely
describe by the variables/states of that fundamental theory. This variable is
commonly called hidden variable and the theory is called hidden variable theory
(HVT). In 1964, John Bell proposed an empirically verifiable criterion to test
for the existence of these HVTs. He derived an inequality, which must be
satisfied by any theory that fulfill the conditions of locality and reality} He
also showed that quantum mechanics, as it violates this inequality, is
incompatible with any local-realistic theory. Later it has been shown that
Bell's inequality can be derived from different set of assumptions and it also
find applications in useful information theoretic protocols. In this review we
will discuss various foundational as well as information theoretic implications
of Bell's inequality. We will also discuss about some restricted nonlocal
feature of quantum nonlocality and elaborate the role of Uncertainty principle
and Complementarity principle in explaining this feature.Comment: 27 pages; This article is a modified version of the tutorial lecture
