The last horizon

Over the past fifty years, science has developed a framework that describes really accurately the history of the origins and evolution of our universe.

At the same time, some of our fundamental questions have no answer. Is the universe finite or infinite? Has space and time had a beginning and will they have an end? Are there other universes besides our own? Amedeo Balbi, professor of astronomy and astrophysics but also refined and skillful scientific populariser, faces these questions.
