A Whisper from Space
Believe it or not, it is now known how and when the universe began. The ' big bang' theory of an exploding universe has been richly confirmed by a whisper of radiation that is all that remains of that first flash.
This programme tells the bizarre story of how the radiation was discovered and how scientists were able to prove an event that happened so long ago.
Professor Philip Morrison helps explain the concepts with the aid of a steam train, a pottery kiln and a length of chain.
The new and exciting discoveries still leave further questions. What happened before the ' big bang '? How will the universe end? Narrator RAY MOORE
