Science of the Impossible

Science fiction says we can travel to other star systems, that we can colonise planets, that space tourism is within our grasp.

So what do the scientists say? Is warp drive possible? How would we live for long periods in space? If humanity's destiny is to live among the stars, what will that do to us as people?

In the programme entitled "Can We Reach The Stars" these questions are investigated.

In "Aliens: Where are They?" the hunt for alien life is under investigation and scientists attempt to answer such questions as; What is the probability of the existence of alien life being somewhere out there? What form might it take? and the age old question, How would we make contact?
