I am by no means a physicist, so maybe someone can explain this to me. Instead of just measuring the time that it takes for the neutrinos to travel the span and comparing that to the known value based on the speed of light, why not shine a beam of light across the distance, measure that time, and then compare the values directly? It seems like that would remove some possible errors in timing and distance measurement.
