Stephen Hawking is one of the worlds most famous scientists. But ALS, also known as Lou Gehrigs Disease, has left him almost totally paralysedand it is progressing. Unable to walk, talk, or write, his only way of communicating is through a computer program that turns a small movement of a finger or the blink of an eye, into words from a vocal synthesizer . But Hawking remains determined to discover a theory of everything, a complete set of rules for the Universe. Where did the Universe come from and where is it going? What is the nature of time? Will it ever come to an end? This programme will explore Hawkings major contributions to the understanding of our Universe - from his revolutionary proof that our Universe originated in a Big Bang; to his ground breaking discovery that Black Holes are not completely black, but rather emit radiation and eventually evaporate and disappear, to his insights on string theory. Will he unlock the secret of creation before his time runs out?
