Time is running out for Earth. If humanity wants to survive the myriad of problems it is confronted with including climate change, asteroid strikes, epidemics and overpopulation, humans would have to leave this planet and find a way to "colonize" another planet in at least the next one hundred years to ensure mankind's survival.
That is the theory of Professor Stephen Hawking and a comprehensive discussion of it featured in the new documentary, Expedition New Earth, as part of the BBC's new science season Tomorrow's World.
Prof. Hawking and his former student Christophe Galfard will travel the world to find out how humans could possibly live in outer space.
Tomorrow's World ran on the air for BBC for 38 years, but the future-gazing show bowed out from television 14 years ago. The corporation and the scientists involved all promise that their new season will be even better.
Another astrophysicist and TV presenter Prof. Brian Cox, who has been helping curate the series acknowledged that the original Tomorrow's World inspired a generation, including him back in the 1970s, but that was just a single TV program. Now, he says the 21st century Tomorrow's World represents so much more- he says it represents the institutions of Britain coming together to inspire also current and future generations, to convince them to embrace the opportunities that science brings. Prof. Cox also added that the return of an even better show would also foster a spirit of curiosity and tolerance, and to embrace the unknown not in fear but in wonder.
The BBC is also getting very able reinforcement from the Royal Society, Open University, London's Science Museum and the Wellcome Trust, to " connect audiences with the brightest minds and institutions in science and technology." BBC director-general Tony Hall said they've come together behind a simple yet very bold ambition- and that is to equip viewers and everyone with the knowledge and understanding they will need to make sense of their lives and the future. Hall said there's no denying that science is changing the world at an extraordinary pace, whether it's the rise of robotics or the demise of antibiotics, traveling to Mars or the arrival of 3D printed food.
The new season will also target to discover Britain's greatest invention by involving the public and asking the public to vote on the innovation which has been the most influential in their lives. Also to be featured are the 10 Things You Need To Know About The Future on BBC Two to be presented by Dr. Hannah Fry. A brand new medical series Operation will follow the pioneering work taking place in the operating theaters of Queen Elizabeth Hospital Birmingham, where surgeons are admirably pushing the boundaries of science.
Other new features for BBC that are science-related include Toughest Job In The Universe that will follow 12 men and women as they undergo the rigors of astronaut selection. BBC Horizon in two controversial episodes will also explore the science of changing gender and whether it is actually possible to cure a psychopath. There's also the second series of How to Stay Young, in which a team of experts apply scientific knowledge to help volunteers slow down the aging process. Radio 4 series will have The Innovators where pioneers in health, technology, science and the environment will be interviewed.
