CERN had an experiment with Gran Sasso to try and find neutrinos. When they used their proton beam they said that since the earth is at a curvature between the two labs, the proton will be fired from one end and will travel underground and then come out when the earth curves on the other end. They managed to find five neutrinos in five years. The protons decayed and produced neutrinos, which have a very low probability to react with any matter. How did CERN manage to succeed with the experiment? The main component of it was measuring the curvature of the earth and shooting the proton using it? What is an explanation for this?
