Ulisse will go to explore the sea, that immensity of water that allowed life to be born and evolve on our planet. An event that will not simply be dedicated to the sea, but above all to the relationship between man and the sea, which began at the beginning of the adventure of Homo Sapiens, and has never been interrupted. So Alberto Angela will be in Genoa, the maritime city par excellence, between the Galata Museum of the Sea, the very rich Aquarium and much more, to retrace the stages of this very long and fascinating human adventure, in its historical and scientific implications. A journey that will develop in two directions: horizontally, exploring the surface of the sea, to learn about the forces that animate it within, the titanic energies capable of moving immense masses of water. And then vertically, into the blue vastness of the sea to get to know the infinite variety of species that populate the oceans, going further and further down, until reaching the bottom of the abyss.
