One cannot expect the media to do proper reporting of political events, UFOs, or anything else. I have even less confidence in their reports on scientific papers. They do seem to make stellar reports on Royal Weddings and the like. >So, if tachyonic neutrinos are not a new concept, why the fuss? >The real issue is not about exceeding the speed of light as >such, nor is it even about the possibility of detecting them.

Causality as it relates to the quantum world is a fascinating topic. I believe causality can be broken without exceeding the speed of light. Instantaneous reactions of entangled photons could be considered a breakdown of causality. It is somewhat similar to one twin in the U.S. being killed by a car and his twin vacationing in England also dies. Not much causality there. One could also argue that causality also ends when an object reaches the speed of light. Since time reaches zero at light velocity, there is no way to have causality without the passage of time. >If you think about it the situation is analogous: the very tiny >superluminal margin is not found from simply timing individual >particles but is calculated by a very complicated statistical >analysis done after the fact on distributed bursts of many >detections, and most importantly the reference frame of >measurement includes both emitter and detector with everything >callibrated and locked together by GPS and atomic clocks.

The other part of the experiment that I wonder about is the spontaneous conversion of neutrinos from one type to another. Sometimes a tau neutrino becomes a muon neutrino and vice versa. Perhaps that oscillation between types of neutrinos results in some type of entangled phenomena that results in a boost to the apparent speed of the neutrino distribution. Listen to 'Strange Days...
