This is the "panspermia" hypothesis, first proposed by astronomers Sir Fred Hoyle
and Dr Chandra Wickramasinghe in 1974.
The lecture will feature a number of prominent scientists, including Professor Chandra Wickramasinghe, who originally discovered bacteria in space with the famous Yorkshire astronomer Sir Fred Hoyle
The professor, an expert on interstellar dust, spent decades working with Sir Fred Hoyle
- a British astronomer and mathematician who was well known for rejecting the Big Bang theory.
Simon's keynote speech was on Sir Fred Hoyle
, and there was also an exhibition of material on Hoyle by Katie Birkwood of St John's College, where Hoyle was a Fellow.
A different theory about life's coming from outer space was published in the same year as Francis Crick's book, 1981, by the astronomer Sir Fred Hoyle
The theory, known as cometary panspermia, pioneered by Chandra Wickramasinghe and the late Sir Fred Hoyle
argues the case that life was introduced to Earth by comets.
He has since helped to found one of the top astronomy departments in Britain and has published more than 25 books on the subject, in collaboration with the late Sir Fred Hoyle
For example, prominent Cambridge astrophysicist Sir Fred Hoyle
concluded that the mathematical probability of life evolving randomly was "so utterly minuscule" (listing the odds of it happening at 1 to 1 plus 40,000 zeroes) that it was too ridiculous to believe.
In a series of three thoughtful lectures, British mathematician and astronomer Sir Fred Hoyle
(1915-2001) explores the aims and motives of scientists, the possibility of life on other planets and the impossibility of space travel, and what daily life on Earth might look like in 500 years.
But astronomer Professor Sir Fred Hoyle
now claims the cosmos had no beginning, with new galaxies simply forming as others moved apart.
The astronomer and science-fiction writer Prof Sir Fred Hoyle
has died aged 86.
The term was coined by English astronomer Sir Fred Hoyle
, who came to doubt his own theory.
