Review on possible gravitational anomalies

TL;DR

This review discusses two gravitational anomalies, the Allais effect and Pioneer spacecraft anomaly, highlighting the lack of conventional explanations and introducing upcoming measurements during 2005 solar eclipses to investigate these phenomena.

Contribution

It provides an updated overview of gravitational anomalies and announces new measurements planned during 2005 solar eclipses to explore these unresolved issues.

Findings

No conventional explanation currently exists for these anomalies.

Upcoming measurements during 2005 solar eclipses aim to gather new data.

The anomalies may require new physics to be explained.

Abstract

This is an updated introductory review of 2 possible gravitational anomalies that has attracted part of the Scientific community: the Allais effect that occur during solar eclipses, and the Pioneer 10 spacecraft anomaly, experimented also by Pioneer 11 and Ulysses spacecrafts. It seems that, to date, no satisfactory conventional explanation exist to these phenomena, and this suggests that possible new physics will be needed to account for them. The main purpose of this review is to announce 3 other new measurements that will be carried on during the 2005 solar eclipses in Panama and Colombia (Apr. 8) and in Portugal (Oct.15).
