One of the major Italian scientists of the twentieth century was, without doubt Ettore Majorana who disappeared under mysterious circumstances in 1938, losing track of him.
One of his greatest theories was one that involved a sub - atomic particles: the neutrino, which he described and never appeared in the experiments. And in the background, a dark universe, made up 95 percent from the field whose nature is unknown to us. To shed light on these mysteries, scientists at the National Laboratory of Gran Sasso fell where it is dark and silence (in a thick rock wall 1400 meters, where you try to understand what are the laws that govern the universe). Yesterday, the bowels of the mountain started an experiment called "Gerda". It was on that a large detector that will capture the "Majorana neutrino", a particle so small and elusive as it is essential to shape the architecture of matter, and therefore the universe.
The heart of the instrument consists of a cylinder of pure germanium, and in particular of an isotope capable of undergoing the double beta decay, could prove the hypothesis of Majorana.
Unfortunately, the experiment will not be fast, since the double beta decay, the origin of the experiment is a very rare phenomenon.
