We live in an in-between universe where things change all right...but according to patterns, rules, or as we call them, laws of nature.

Books permit us to voyage through time, to tap the wisdom of our ancestors.
Carl Sagan
Image
Human history can be viewed as a slowly dawning awareness that we are members of a larger group.
Carl Sagan

If you want to make a [rhubarb] pie from scratch, first you have to create the universe.
Carl Sagan
Image
The method of science is tried and true. It is not perfect, it's just the best we have. And to abandon it, with its skeptical protocols, is the pathway to a dark age.
Carl Sagan
Image
After the earth dies, some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being - and they will know nothing of a place once called Earth.
Carl Sagan
Image
We are made of starstuff.
Carl Sagan
Image
You're capable of such beautiful dreams and such horrible nightmares.
Carl Sagan
Image
There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.
Carl Sagan
Image
For all I know we may be visited by a different extraterrestrial civilization every second Tuesday, but there's no support for this appealing idea. The extraordinary claims are not supported by extraordinary evidence.
Carl Sagan
Image
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.
Carl Sagan

We are like butterflies who flutter for a day and think it is forever.
Carl Sagan
Image
Understanding is a kind of ecstasy
Carl Sagan
Image
The wind whips through the canyons of the American Southwest, and there is no one to hear it but us - a reminder of the 40,000 generations of thinking men and women who preceded us, about whom we know almost nothing, upon whom our civilization is based.
Carl Sagan
Image
Except in pure mathematics, nothing is known for certain (although much is certainly false).
Carl Sagan

Otherwise we don't run the government the government runs us
Carl Sagan
Image
We humans look rather different from a tree. Without a doubt we perceive the world differently than a tree does. But down deep, at the molecular heart of life, the trees and we are essentially identical.
Carl Sagan
Image
Is mankind alone in the universe? Or are there somewhere other intelligent beings looking up into their night sky from very different worlds and asking the same kind of question?
Carl Sagan
Image
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.

Advances in medicine and agriculture have saved vastly more lives than have been lost in all the wars in history.

Imagine we could accelerate continuously at 1 g-what we're comfortable with on good old terra firma-to the midpoint of our voyage, and decelerate continuously at 1 g until we arrive at our destination. It would take a day to get to Mars, a week and a half to Pluto, a year to the Oort Cloud, and a few years to the nearest stars.
