Hmmm read this on wikipedia
"Sagan again revealed his views on interstellar travel in his 1980 Cosmos series. He rejected the idea that UFOs are visiting Earth, maintaining that
the chances any alien spacecraft would visit the Earth are vanishingly small. However, in another episode he said the stars would "beckon" to
humanity, and described the Bussard ramjet as one way humans might achieve interstellar travel. In one of his last written works, Sagan again claimed
that there was no evidence that aliens have actually visited the Earth, either in the past or present (Sagan, 1996: 81-96, 99-104)."
This is the first time I heard of the Bussard ramjet.
I'm surprised that the same man who wrote "Contact" would make such a statement. VIVA LAS VEGA!
