Yes, it is about OPERA experiment, but it has nothing to do with neutrinos. Can someone try to explain how is it technically possible that faulty connection could be responsible for additional signal delay? I understand it can make the signal unreadable, but delayed by 60 ns? Main reason I can't understand the situation is that even if the link is faulty, signal still propagates with the same speed - approximately 1 feet per 1 ns. 60 ns is equivalent 60 feet. Signal path didn't change that much. What is the source of the delay? What am I missing?
