The immense distances to the stars and the galaxies mean that we see everything ins pace int he past, some as they were before the Earth came to be. Telescopes are time machines.

More quotes by Carl Sagan
Every thinking person fears nuclear war, and every technological state plans for it. Everyone knows it is madness, and every nation has an excuse
Carl Sagan
UFOs: The reliable cases are uninteresting and in the interesting cases are unreliable.
Carl Sagan
I don't want to believe. I want to know.
Carl Sagan
Our ancestors worshipped the Sun, and they were not that foolish. It makes sense to revere the Sun and the stars, for we are their children.
Carl Sagan
Science arouses a soaring sense of wonder. But so does pseudoscience. Sparse and poor popularizations of science abandon ecological niches that pseudoscience promptly fills. If it were widely understood that claims to knowledge require adequate evidence before they can be accepted, there would be no room for pseudoscience.
Carl Sagan
Extraordinary claim requires extraordinary proof.
Carl Sagan
For all its material advantages, the sedentary life has left us edgy, unfulfilled, even after 400 generations in villages and cities, we haven't forgotten: The open road still softly calls like a nearly forgotten song of childhood.
Carl Sagan
The fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses.
Carl Sagan
The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.
Carl Sagan
The universe seems neither benign nor hostile, merely indifferent.
Carl Sagan
Observation: I can't see a thing. Conclusion: Dinosaurs.
Carl Sagan
If we ruin the earth, there is no place else to go
Carl Sagan
We can always take but never give.
Carl Sagan
Which aspects of our nature will prevail is uncertain, particularly when our visions and prospects are bound to one small part of the small planet Earth. But up there in the Cosmos an inescapable perspective awaits.
Carl Sagan
Scientists make mistakes. Accordingly, it is the job of the scientist to recognize our weakness, to examine the widest range of opinions, to be ruthlessly self-critical. Science is a collective enterprise with the error-correction machinery often running smoothly.
Carl Sagan
Science is a way to call the bluff of those who only pretend to knowledge. It is a bulwark against mysticism, against superstition, against religion misapplied to where it has no business being.
Carl Sagan
Books break the shackles of time, proof that humans can work magic.
Carl Sagan
There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.
Carl Sagan
But nature is always more subtle, more intricate, more elegant than what we are able to imagine.
Carl Sagan
Understanding is a kind of ecstasy
Carl Sagan
