In this groundbreaking film, Professor Hawking teams up with engineer and radio astronomy expert Professor Danielle George and his former student, Christophe Galfard, to explore the possibilities of humans reaching for the stars and settling on other planets. As they journey around the world, they engage with leading scientists, technologists, and engineers who are tackling some of our most profound questions: Is there another planet we could inhabit? How can we traverse the immense distances of space to reach it? What will it take to survive the journey? And how can we establish a new human society on an alien world? From the Atacama Desert to the Arctic’s remote regions, the film delves into the latest breakthroughs in astronomy, biology, and rocket science, revealing a realm of cutting-edge research. This program demonstrates that Professor Hawking’s vision is not as far-fetched as it might seem, showing that the line between science fiction and science reality is thinner than we ever imagined.
