Expedition New Earth: Stephen Hawking explores the possibility of humans inhabiting other planets.

SYNOPSIS

Part one of two. Physicist Stephen Hawking thinks the human species will have to populate a new planet within 100 years if it is to survive, with climate change, pollution, deforestation, pandemics and population growth making life on Earth increasingly precarious. In this programme, he is joined by engineering professor Danielle George and his former student Christophe Galfard to examine if humans could relocate to other planets, travelling the globe to meet scientists, technologists and engineers working on the means and method.
