Research paper thumbnail of Rotation of the Universe and Generalised Gaussian Metrics

Arxiv preprint arXiv:0801.1954, Jan 1, 2008

Robertson-Walker's metric has been employed with proper-time, in its standard applications; the generalised Gaussian metric imply in the use of a non-constant temporal ...

Research paper thumbnail of Are Mass and Length Quantized?

Arxiv preprint arXiv:0707.3290, Jan 1, 2007

Research paper thumbnail of An alternative form for Raychaudhuri's equation

International Journal of Theoretical Physics, Jan 1, 1994

We derive a form of the equation that shows how this happens.

Research paper thumbnail of Inflation in Brans-Dicke theory for the radiation universe

International journal of theoretical physics, Jan 1, 1992

Research paper thumbnail of General relativity with variable speed of light and Pioneers anomaly

Astrophysics and Space Science, Jan 1, 2011

This deceleration may decrease with time, as we calculated. This is ...

Research paper thumbnail of Density perturbations in a Brans-Dicke cosmological model

International journal of theoretical physics, Jan 1, 1990

The model has growing instabilities, but not of exponential character.

Research paper thumbnail of Amplification of gravitational waves in scalar-tensor accelerating lambda-Universes

Phys. 29, 1411–1414, 2009), we obtain solutions for the amplification of gravitational waves in the models. The solutions consider a perfect gas equation of state, ...

Research paper thumbnail of The two pioneers anomalies and universal rotation

Astrophysics and Space Science, Jan 1, 2011

The first Pioneers Anomaly is the deceleration of about −9 × 10−8 cm·s −2 suffered by NASA space-... more The first Pioneers Anomaly is the deceleration of about −9 × 10−8 cm·s −2 suffered by NASA space-probes trav-eling towards outer space (Anderson et al. 2002). It has no acceptable explanation within local Physics, but if we resort to Cosmology, it could be explained by the rotation of ...
