Best Of Carl Sagan's Cosmos & We Are Here: The Pale Blue Dot (HD)

"The greatest thrill for me in reliving this adventure has been not just that we have completed the preliminary reconnaissance with spacecraft of the entire solar system, and not just that we've discovered astonishing structures in the realm of galaxies, but especially that some of Cosmos's boldest dreams about this world are coming closer to reality.

Since this series' maiden voyage, the impossible has come to pass: Mighty walls that maintained insuperable ideological differences have come tumbling down; deadly enemies have embraced and begun to work together. The imperative to cherish the Earth and protect the global environment that sustains all of us has become widely accepted, and we've begun, finally, the process of reducing the obscene number of weapons of mass destruction. Perhaps we have, after all, decided to choose life.

But we still have light years to go to ensure that choice. Even after the summits and the ceremonies and the treaties, there are still some 50,000 nuclear weapons in the world—and it would require the detonation of only a tiny fraction of them to produce a nuclear winter, the predicted global climatic catastrophe that would result from the smoke and the dust lifted into the atmosphere by burning cities and petroleum facilities.

The world scientific community has begun to sound the alarm about the grave dangers posed by depleting the protective ozone shield and by greenhouse warming, and again we're taking some mitigating steps, but again those steps are too small and too slow. The discovery that such a thing as nuclear winter was really possible evolved out of the studies of Martian dust storms. The surface of Mars, fried by ultraviolet light, is also a reminder of why it's important to keep our ozone layer intact. The runaway greenhouse effect on Venus is a valuable reminder that we must take the increasing greenhouse effect on Earth seriously.

Important lessons about our environment have come from spacecraft missions to the planets. By exploring other worlds we safeguard this one. By itself, I think this fact more than justifies the money our species has spent in sending ships to other worlds. It is our fate to live during one of the most perilous and, at the same time, one of the most hopeful chapters in human history.

Our science and our technology have posed us a profound question. Will we learn to use these tools with wisdom and foresight before it's too late? Will we see our species safely through this difficult passage so that our children and grandchildren will continue the great journey of discovery still deeper into the mysteries of the Cosmos?

That same rocket and nuclear and computer technology that sends our ships past the farthest known planet can also be used to destroy our global civilization.

Exactly the same technology can be used for good and for evil. It is as if there were a God who said to us, “I set before you two ways: You can use your technology to destroy yourselves or to carry you to the planets and the stars. It's up to you.”

"From this distant vantage point, the Earth might not seem of particular interest. But for us, it's different. Consider again that dot. That's here, that's home, that's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.

It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known."

"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 Zemecki's 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."

So, what does Stephen Hawking's The Grand Design tell us about God? - By Peter Galison - Slate Magazine

Religious conflict rolls across the Middle East, Southeast Asia, and Central Asia. A tiny, loony sect threatens to burn the Quran, and the world's leaders respond. You might not think there could possibly be any room in the headlines for a debate about the divine stirred up by a mere physics book. Think again. Several weeks ago, the London Times devoted much of its front page to heralding just that: "Hawking: God did not create Universe: The Big Bang was inevitable consequence of laws of physics, says Britain's most eminent scientist." In a high-profile flurry of attention that any author would envy, the archbishop of Canterbury, Britain's chief rabbi, and the chair of interfaith relations of the Muslim Council of Britain have all locked arms against Stephen Hawking's anti-God fluctuation in his new book.

M51 Whirlpool Galaxy Black Hole - Percy Bysshe Shelley On God & Virtue

via en.wikiquote.org

"We live and move and think; but we are not the creators of our own origin and existence. We are not the arbiters of every motion of our own complicated nature; we are not the masters of our own imaginations and moods of mental being. There is a Power by which we are surrounded, like the atmosphere in which some motionless lyre is suspended, which visits with its breath our silent chords at will.
Our most imperial and stupendous qualities — those on which the majesty and the power of humanity is erected — are, relatively to the inferior portion of its mechanism, active and imperial; but they are the passive slaves of some higher and more omnipotent Power. This Power is God; and those who have seen God have, in the period of their purer and more perfect nature, been harmonized by their own will to so exquisite consentaneity of power as to give forth divinest melody, when the breath of universal being sweeps over their frame. That those who are pure in heart shall see God, and that virtue is its own reward, may be considered as equivalent assertions. The former of these propositions is a metaphorical repetition of the latter. The advocates of literal interpretation have been the most efficacious enemies of those doctrines whose nature they profess to venerate."
- Percy Bysshe Shelley in Essay on Christianity (1859)
