For the development of our theories, we perform experiments focused on
the detection of very elusive particles or on the observation of very
rare phenomena. The results can shed new light on our understanding of
the Universe, but their detection is a real challenge. Trillions of
neutrinos, for instance, go through our body every second without
stopping. This means that very few events will be recorded in our
detectors, in some cases only a few per year! So any spurious signal,
induced, for instance, by particles generated in the cosmic ray showers
may overpower the expected signals in the same way sunlight hides stars
during the day. We can get a “cosmic night“ by going underground or
undersea, where cosmic rays are mostly absorbed.
