Carl Sagan·1970There is a place with four suns in the sky — red, white, blue, and yellow; two of them are so close together that they touch, and star-stuff flows between them. I know of a world with a million moons. I know of a sun the size of the Earth — and made of diamond. There are atomic nuclei a few miles across which rotate thirty times a second. There are tiny grains between the stars, with the size and atomic composition of bacteria. There are stars leaving the Milky Way, and immense gas clouds falling into it. There are turbulent plasmas writhing with X- and gamma-rays and mighty stellar explosions. There are, perhaps, places which are outside our universe. The universe is vast and awesome, and for the first time we are becoming a part of it.
Miyamoto Musashi·1645People in this world look at things mistakenly, and think that what they do not understand must be the void. This is not the true void. It is bewilderment.
Lewis Thomas·1974Viewed from the distance of the moon, the astonishing thing about the earth, catching the breath, is that it is alive.
