„We are so tiny under the vast sky, our mankind home is just a tiny speck in the immeasurable reaches of a boundless universe, we find an immense and highly ordered system of galaxies stars and planets, all moving with great precision, the heavenly wisdom vibrates in our hearts.“

— Alexis Karpouzos
„Our home, pale blue dot in the vastness of universe's untouched beauty, a tiny spherical world, afloat in a immensity of space and time. Here for a moment, and then we're leaving for the eternity. In the school of mortality we learn to acrobat over the abyss.“
— Alexis Karpouzos
„Once we overcome our fear of being tiny, we find ourselves on the threshold of a vast and awesome Universe that utterly dwarfs — in time, in space, and in potential — the tidy anthropocentric proscenium of our ancestors.“
— Carl Sagan
„Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.“
— Carl Sagan
„A tiny blue dot set in a sunbeam. Here it is. That's where we live. That's home. We humans are one species and this is our world. It is our responsibility to cherish it. Of all the worlds in our solar system, the only one so far as we know, graced by life.“
— Carl Sagan
„For as long as there been humans we have searched for our place in the cosmos. Where are we? Who are we? We find that we live on an insignificant planet of a hum-drum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people. This perspective is a courageous continuation of our penchant for constructing and testing mental models of the skies; the Sun as a red-hot stone, the stars as a celestial flame, the Galaxy as the backbone of night.“
— Carl Sagan
„We declare our own triviality on a small speck of dirt circling a small star at the rim of one countless galaxies and ignore the heroic insolence of the declaration. We have diminished the world of God and man in a universe ablaze with all the glories that contradict that diminution.Of man and God.“
— William Golding
„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.“
— Carl Sagan
