Planet Earth has been home to humankind for over 200,000 years, but with a population of 7.3 billion and counting and limited resources, this planet might not support us forever. Professor 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, our own planet is becoming increasingly precarious.
For many years Black Holes were believed to be myths, but modern astronomy is proving the reality of the most powerful destroyers in the Universe.

The multiverse hypothesis, suggesting that our universe is but one of perhaps infinitely many, speaks to the very nature of reality. Join physicist Brian Greene, cosmologists Alan Guth and Andrei Linde, and philosopher Nick Bostrom as they discuss and debate this controversial implication of forefront research and explore its potential for redefining the cosmic order. Moderated by Robert Krulwich and featuring an original musical interlude, inspired by parallel worlds, by DJ Spooky.

All life on Earth started as single-cell bacteria and stayed like that for two billion years. So even if we do find alien life out there, what are the chances of that life being complex like us? Astronaut host – Mae Jemison.

Kevin explores life in orbit on board the Station. As Tim settles in to his new home he sends special reports about what it takes to live and work in space. Four hundred kilometres above the Earth, hurtling at a speed of 17,500mph, astronauts' bones and muscles waste away, the oxygen they breathe is artificially made, and they face constant threats from micrometeorites, radiation and extreme temperatures. If a medical emergency strikes, Tim is a very long way from home. In its 15-year lifetime, the International Space Station has never had a major accident. With a British astronaut in orbit, gravity-defying experiments and guest astronauts in the lecture theatre, Dr Fong shows us how to survive life in orbit.
