General relativity and quintessence explain the Pioneer anomaly

J. P. Mbelek

The anomalous time depending blueshift, the so-called "Pioneer anomaly", that was detected in the radio-metric data from Pioneer 10/11, Ulysses and Galileo spacecraft may not resul…

A scalar field modelling of the rotational curves of spiral galaxies

J. P. Mbelek

In a previous work \cite{mbeleka}, we have modelled the rotation curves (RC) of spiral galaxies by including in the equation of motion dynamical terms from an external real self-in…

Comment on "Constraining a possible dependence of Newton's constant on the Earth's magnetic field"

J. P. Mbelek

Recently A. Rathke has argued that the KK model explanation of the discrepant measurements of Newton's constant is already ruled out due to Eötvös experiments by several orders…

Possible evidence from laboratory measurements for a latitude and longitude dependence of G

J. P. Mbelek, M. Lachièze-Rey

Stability arguments suggest that the Kaluza-Klein (KK) internal scalar field, , should be coupled to some external fields. An external bulk real scalar field, , minimally cou…

Theoretical Necessity of an External Scalar Field in the Kaluza-Klein Theory (I)

J. P. Mbelek, M. Lachieze-Rey

We show that the principle of least action is generally inconsistent with the usual Kaluza-Klein program, the higher dimensional Einstein-Hilbert action being unbounded from below.…

Long-range acceleration induced by a scalar field external to gravity and the indication from Pioneer 10/11, Galileo and Ulysses Data

J. P. Mbelek, M. Lachièze-Rey

We suggest an explanation of the "Pioneer effect" based on the interaction of the spacecraft with a long-range scalar field, . The scalar field under consideration is external t…
