Renowned philosopher *AC Grayling* returns to the King’s Hall with an out-of-this-world question: who owns the moon? As Earth’s superpowers and wealthiest corporations turn their eyes to the stars, Grayling considers the future of space and the history of the places which no one owned and everyone made a grab for, from feudal common land, through the rules of the sea, to the vast, nationless expanse of Antarctica. Can we avoid repeating the competition and conflicts of the past in this new space race? Join Grayling as he confronts frontiers, past, present and future.
