This paper proposes an explanation for the Pioneer anomaly: an unexplained Sunward acceleration of 8.74 ± 1.33 × 10 −10 ms −2 seen in the behaviour of the Pioneer probes. Two hypotheses are made. (1) Inertia is a reaction to Unruh radiation and (2) this reaction is weaker for low accelerations because some wavelengths in the Unruh spectrum do not fit within a limiting scale (twice the Hubble distance) and are disallowed: a process similar to the Casimir effect. When these ideas are used to…

Modelling the flyby anomalies using a modification of inertia

The flyby anomalies are unexplained velocity jumps of 3.9, −4.6, 13.5, −2, 1.8 and 0.02 mm s −1 observed near closest approach during the Earth flybys of six spacecraft. These flybys are modelled

The Pioneer Anomaly

A significant amount of information is provided on the design, operations and behavior of the two Pioneers during their entire missions, including descriptions of various data formats and techniques used for their navigation and radio-science data analysis.

Mathematics of Dynamic Universe Model Explain Pioneer Anomaly

A new type of tensor mathematics used in Dynamic universe model can be used to solve the Pioneer Anomaly. “The Pioneer anomaly or Pioneer effect is the observed deviation from expectations of the

The Tajmar effect from quantised inertia

The Tajmar anomaly is an unexplained acceleration observed by gyroscopes close to, but isolated from, rotating rings cooled to 5 K. The observed ratio between the gyroscope and ring accelerations was

Can the Tajmar effect be explained using a modification of inertia?

The Tajmar effect is an unexplained acceleration observed by accelerometers and laser gyroscopes close to rotating supercooled rings. The observed ratio between the gyroscope and ring accelerations

Minimum accelerations from quantised inertia

It has recently been observed that there are no disc galaxies with masses less than 109M⊙ and this cutoff has not been explained. It is shown here that this minimum mass can be predicted using a

A Toy Cosmology Using a Hubble-Scale Casimir Effect

The visible mass of the observable universe agrees with that needed for a flat cosmos, and the reason for this is not known. It is shown that this can be explained by modelling the Hubble volume as a

Superluminal Travel from Quantised Inertia

Special relativity predicts that the inertial mass of an object is infinite at the speed of light (c) causing zero acceleration and producing a cosmic speed limit. Here, a new model for inertia is



Study of the anomalous acceleration of Pioneer 10 and 11

Our previous analyses of radio Doppler and ranging data from distant spacecraft in the solar system indicated that an apparent anomalous acceleration is acting on Pioneer 10 and 11, with a magnitude

The Pioneer anomaly: seeking an explanation in newly recovered data

The Pioneer 10 and 11 spacecraft yielded very accurate navigation in deep space that was, however, limited by a small, anomalous frequency drift of their carrier signals received by the

Dynamics with a Nonstandard Inertia-Acceleration Relation: An Alternative to Dark Matter in Galactic Systems

Abstract We investigate particle dynamics that is governed by a nonstandard kinetic action of a special form. We are guided by a phenomenological scheme-the modified dynamics (MOND)-that imputes the

Gravitational solution to the Pioneer 10/11 anomaly

A fully relativistic modified gravitational theory including a fifth force skew-symmetric field is fitted to the Pioneer 10/11 anomalous acceleration. The theory allows for a variation with distance

Relativistic gravitation theory for the MOND paradigm

The modified newtonian dynamics (MOND) paradigm of Milgrom can boast of a number of successful predictions regarding galactic dynamics; these are made without the assumption that dark matter plays a

Modified Newtonian dynamics as an alternative to dark matter

▪ Abstract Modified Newtonian dynamics (MOND) is an empirically motivated modification of Newtonian gravity or inertia suggested by Milgrom as an alternative to cosmic dark matter. The basic idea is

MOdified Newtonian Dynamics (MOND) is evolving from an empirical to a decent theory respect- ing fundamental physics after Bekenstein (2004) showed that lensing and Hubble expansion can be modeled

A modification of the newtonian dynamics as a possible alternative to the hidden mass hypothesis

The author considers the possibility that there is not, in fact, much hidden mass in galaxies and galaxy systems. If a certain modified version of the Newtonian dynamics is used to describe the

Notes on black-hole evaporation

This paper examines various aspects of black-hole evaporation. A two-dimensional model is investigated where it is shown that using fermion-boson cancellation on the stress-energy tensor reduces the
