To coincide with the switch-on of the Large Hadron Collider, the world's largest particle accelerator complex, Professor Jim Al Khalili from the University of Surrey delves into over 50 years of the BBC science archive to tell the story behind the emergence of one of the greatest theories of modern science, the Big Bang. The remarkable idea that our universe simply began from nothing has not always been accepted with the conviction it is today and, from fiercely disputed leftfield beginnings, took the best part of the 20th century to emerge as the triumphant explanation of how the universe began. Using curious horn-shaped antennas, U-2 spy planes, satellites and particle accelerators, scientists have slowly pieced together the cosmological jigsaw, and this documentary charts the overwhelming evidence for a universe created by a Big Bang. Professor Al-Khalili comments: "This one-off documentary was made by the BBC Horizon team and was great fun to be involved with. The archive footage is fantastic too."
