" "The cosmic calendar compresses the local history of the universe into a single year. If the universe began on January 1st it was not until May that the Milky Way formed. Other planetary systems may have appeared in June, July and August, but our Sun and Earth not until mid-September. Life arose soon after.

About Carl Sagan
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

Additional quotes by Carl Sagan
Placebos can be astonishingly effective, especially for colds, anxiety, depression, pain, and symptoms that are plausibly generated by the mind. Conceivably, endorphins — the small brain proteins with morphinelike effects — can be elicited by belief. A placebo works only if the patient believes it’s an effective medicine. Within strict limits, hope, it seems, can be transformed into biochemistry.

I've been searching, Eleanor. After all these years, believe me, I know the truth when I see it. Any faith that admires truth, that strives to know God, must be brave enough to accomodate the universe. I mean the real universe. All those light-years. All those worlds. I thing of the scope of your universe, the opportunities it affords the Creator, and it takes my breath away. It's much better than bottling Him up in one small world. I never liked the idea of Earth as God's green footstool. It was too reassuring, like a children's story... like a tranquilizer. But your universe has room enough, and time enough, for the kind of God I believe in.
