The Pioneer Anomaly and a Rotating Godel UniverseThe Pioneer Anomaly represents an intriguing problem for fundamental physics whose scope still seems to baffle the best of explanations. It involves one of the most precise fine-scale acceleration measurements possible in the space age as the Pioneer 10/11 spacecraft reached distances of 20-70 AU from the Sun. An anomalous acceleration directed back toward the Sun of approx. 8x10(exp -10) m/sq s was discovered. The problem will be summarized and an up-to-date overview of possible explanations for this surprising result will be given. It may even be possible that our cosmic environment such as expansion dynamics and/or dark energy could be influencing the behavior of planets and spacecrafts within our local solar system. Then a new possibility, that of a rotating Godel Universe, will be introduced and examined.
