Four online books about life from comets and space in general
The Cosmic Ancestry Web site, devoted to proving that all life on Earth came
via panspermia, has recently posted copies of four books by Fred Hoyle and
Chandra Wickramasinghe published in the 1980s.
Certain ideas in these works have become a bit more accepted, or at least
less further from the mainstream than when they first came out. They do
make for very interesting reading whether you agree with their ideas or not.
The titles are in the URLs.
