Carl Sagan's Legacy
Please watch. He had a love for things that we talk about and even dream about. 5 Miutes from your time will not kill you or make you a kook. Please listen to the voice for once.

Even if we cannot change the environment in time, even if this planet is doomed, at least we might still have time to change ourselves and our behavior toward one another.

"We were asking the Americans, 'Are you operating a prototype aircraft in our airspace?' That, of course, was nonsense. You simply would not do that from a diplomatic and political point of view. It would undermine the entire structure of NATO if you were putting things through someone else's airspace, particularly a close ally, without seeking the proper diplomatic clearance. But we had to ask. And the Americans, having had similar reports, I guess, since the Hudson Valley wave [New York state, mid-1980s], had been quietly asking us if we had some large, triangular shaped object that could go from 0 to Mach 5 in a second. Our response was that we wished we did. This was the bizarre situation: that we were chasing the Americans, and the Americans were chasing us."

Don't get me wrong, I liked and admired Carl. I felt I could have given him a different take on UFOs to "convince" him not to be so close-minded about them. But that "beautiful" discourse is really poetic diarrhrea. Eveything he said there could have been whittled down to 2 words: human beings!

"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 in 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 the dot on scarcely distinguishable inhabitants of some other corner of the dot. 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. It is up to us.

Prof Says Beings From Outer Space Have Visited Earth
Associated Press, November 26, 1962
LOS ANGELES. (AP) - Some of the best scientific minds in the country were stumped when a slender, dark-haired young man chalked on the blackboard this equation:
N equals R FP NE FL FI FC L.
The speaker was Dr. Carl Sagan, a 28 year-old assistant professor of astronomy at Harvard University.
His audience consisted of several hundred members of the American Rocket Society, gathered for his luncheon address.
The equation was his way of expressing the mathematical probability that intelligent beings from outer space have visited earth.
Sagan soberly explained that in his equation N Stands for the number of advanced technical civilizations in the universe possessing the capability of interstellar communication.
R is the mean rate of star formation averaged over the lifetime of the galaxy.
FP is the fraction of stars with planetary systems.
NE is the mean number of planets in each system with environments favorable for the origin of life.
FL is the fraction of such planets on which life does develop.
FI is the fraction of such inhabited planets on which intelligent life with manipulative abilities rises during the lifetime of the local sun.
FC is the fraction of planets populated by intelligent beings on which advanced technical civilizations rises.
And L is the lifetime of this technical civilization.
Sagan said information in his formula is based on current estimates by astronomers. In making calculations, he assigned each symbol an arbitrary numerical value.
As expressed in numbers, Sagan said, the formula means that at least 1 million of the 100 billion stars in our Milky Way galaxy have planets which have developed civilizations capable of travel between the stars.
"Let's say that each of these civilizations sends out one interstellar expedition per year," he said.
"That means that every star, such as our sun, would be visited at least once every million years. In some systems where these beings found life, they would make more frequent visits. There's a strong probability, then, that they have visited earth every few thousand years.
"It is not out of the question that artifacts of these visits still exist or even that some kind of base is maintained, possibly automatically, within the solar system, to provide continuity for successive expeditions.
"Because of weathering and the possibility of detection and interference by the inhabitants of earth it would be preferable not to erect such a base on the earth's surface. The moon seems one reasonable alternative."
"Forthcoming photographic reconnaissance of the moon from space vehicles - particularly of the back - might bear these possibilities in mind."
At a news conference Sagan predicted man himself would be capable of interstellar flight at close to the speed of light "within a century or two."
Asked if he believed in flying saucers, he said: "I do believe there are objects which have hot be identified."
