Gravity tests and the Pioneer anomaly |
Abstract _ |
Validity of general relativity has been confirmed at distance scales ranging from the millimeter to the size of planetary orbits. But windows remain open for potential violations at shorter or longer scales. The anomalous acceleration recorded on Pioneer 10/11 probes on their escape trajectories outwards the solar system might constitute a first hint that gravity laws should be modified at large scales. Observation of this "Pioneer anomaly" will be presented and the question of its compatibility with other gravity tests in the solar system then discussed. |
