Carl Edward Sagan, Ph.D. (1934-1996) was an American astronomer, astrochemist, author, and highly successful popularizer of astronomy, astrophysics and other natural sciences. He pioneered exobiology and promoted the Search for Extra-Terrestrial Intelligence (SETI).

He is world-famous for writing popular science books and for co-writing and presenting the award-winning 1980 television series "Cosmos: A Personal Voyage", which has been seen by more than 600 million people in over 60 countries, making it the most widely watched PBS program in history.

A book to accompany the program was also published. He also wrote the novel "Contact", the basis for the 1997 Robert Zemeckis film of the same name starring Jodie Foster.

During his lifetime, Sagan published more than 600 scientific papers and popular articles and was author, co-author, or editor of more than 20 books. In his works, he frequently advocated skeptical inquiry, secular humanism, and the scientific method.

Scientists, explorers and teachers have always been humankind's true leaders; Sagan was all three. An extraordinary man...

If only Carl could see what today's technology and astronomical knowledge is like... R.I.P Carl. :(

Audio synch out for everyone or just me?

@butlerlog Correct me if I'm wrong because I did not investigate this, but I'm assuming the people of the time did not know nearly how far away the sun really is.

[butlerlog]

@ksthebest Depends how far away the source of light is, for a candle, you are correct, but with the sun, the rays are as close to parallel as matters in this matter.

I love the video an Carl Sagan, but I have to point this out: the shadows could also e different on a flat world, just like a single light in a room casts different shadows.

@crocfme Absolutely. Love him.
