yvette prieto: Breaking the Light Barrier
Meanwhile a less reported faster than light2 experiment threatens the same law of physics, namely the light barrier. As I understand it Einstein's equations are such that nothing can exceed the speed of light.
Some experiments can show that adjacent waves can propagate faster than light, but physicists argue that information or matter cannot travel that way. Quantum entanglement would seem to break the light barrier also. There again physicists argue against the phenomena; Einstein called it "spooky behavior at a distance."
Recently the OPERA experiment measured the speed of neutrinos between CERN in Geneva and Gran Sasso National Laboratory in L'Aquila, Italy, a distance of 730 k, at a speed faster than C, the speed of light. This claim was widely questioned with all sorts of doubting questions of error. However, on November 17 investigators repeated the experiment with even finer measuring devices confirming the earlier experiment.
Physicists still remain doubtful. The Fermilab in Batavia, Illinois plans an attempt to duplicate the results in early 2012.
From an aviation standpoint the light barrier looms as just one more challenge, as was the romantic conquest of the Michael -- and best to you both.
