Submission + - Gamma Ray Anomaly Could Test String Theory (sciam.com)
exploder writes: String theory is notorious for its lack of testable predictions. But if the MAGIC gamma-ray telescope team's interpretation is correct, then a delay in the arrival of higher-energy gamma rays could point to a breakdown of relativity theory. A type of "quantum lensing effect" is postulated to cause the delay, which is approximateley four minutes over a half-billion year journey.
