Historic Panspermia Lectures from the Archive
The theory of cometary panspermia was developed by Professor Chandra Wickramasinghe and the late Sir Fred Hoyle from the 1980s onwards. The Sri Lanka Broadcasting Corporation invited Prof Wickramasinghe to deliver the inaugural lecture in a new series “Expanding Mind” on 3 April 1980. In December 1982 Fred Hoyle gave the opening lecture in a conference organised by the Sri Lanka Institute of Fundamental Studies in the presence of H.E. President J.R. Jayawardene, the President of Sri Lanka. These lectures are available to listen to or watch below:
The origins of life on Earth – Chandra Wickramasinghe (April 1980)
From virus to cosmology – Fred Hoyle (December 1982)
We Are The Aliens (BBC documentary, 2006, including interviews with Fred Hoyle and Chandra Wickramasinghe)
