A Quote by Arthur C. Clarke

In this single galaxy of ours there are eighty-seven thousand million suns. [...] In challenging it, you would be like ants attempting to label and classify all the grains of sand in all the deserts of the world. [...] It is a bitter thought, but you must face it. The planets you may one day possess. But the stars are not for man.
One billion grains of sand come into existence in the world each second. That's a cyclical process. As rocks and mountains die, grains of sand are born. Some of those grains may then cement naturally into sandstone. And as the sandstone weathers, new grains break free. Some of those grains may then accumulate on a massive scale, into a sand dune.
A hundred thousand million Stars make one Galaxy; A hundred thousand million Galaxies make one Universe. The figures may not be very trustworthy, but I think they give a correct impression.
In this way, Edwin Hubble worked out the distances to nine different galaxies. We now know that our galaxy is only one of some hundred thousand million that can be seen using modern telescopes, each galaxy itself containing some hundred thousand million stars.
Since stars appear to be suns, and suns, according to the common opinion, are bodies that serve to enlighten, warm, and sustain a system of planets, we may have an idea of the numberless globes that serve for the habitaton of living creatures.
There are 15 constants- the gravitational constant, various constants about the strong and weak nuclear force, etc.- that have precise values. If any one of those constants was off by even one part in a million, or in some cases, by one part in a million million, the universe could not have actually come to the point where we see it. Matter would not have been able to coalesce, there would have been no galaxy, stars, planets or people
People sometimes accuse me of knowing a lot. "Stephen," they say, accusingly, "you know a lot." This is a bit like telling a person who has a few grains of sand clinging to him that he owns much sand. When you consider the vast amount of sand there is in the world such a person is, to all intents and purposes, sandless. We are all sandless. We are all ignorant. There are beaches and deserts and dunes of knowledge whose existance we have never even guessed at, let alone visited.
In space there are countless constellations, suns and planets; we see only the suns because they give light; the planets remain invisible, for they are small and dark. There are also numberless earths circling around their suns.
God is infinite, so His universe must be too. Thus is the excellence of God magnified and the greatness of His kingdom made manifest; He is glorified not in one, but in countless suns; not in a single earth, a single world, but in a thousand thousand, I say in an infinity of worlds.
If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.
One in 200 stars has habitable Earth-like planets surrounding it - in the galaxy, half a billion stars have Earth-like planets going around them - that's huge, half a billion. So when we look at the night sky, it makes sense that someone is looking back at us.
What is it all but a trouble of ants in the gleam of a million million of suns?
... the only other place comparable to these marvelous nether regions, must surely be naked space itself, out far beyond atmosphere, between the stars, where sunlight has no grip upon the dust and rubbish of planetary air, where the blackness of space, the shining planets, comets, suns, and stars must really be closely akin to the world of life as it appears to the eyes of an awed human being, in the open ocean, one half mile down.
I'll tell you truly: I value my thought and work terribly, but in essence - think about it - this whole world of ours is just a bit of mildew that grew over a tiny planet. And we think we can have something great - thoughts, deeds! They're all grains of sand
Every particle of the world is a mirror. In each atom blazes forth the light of a thousand suns. Open the heart of a raindrop and you will find a hundred oceans. In a grain of sand lies the seed of a thousand beings.
There are 400 billion stars out there, just in our galaxy alone. If just one out of a million of those had planets, and just one in a million of those had life, and just one out of a million of those had intelligent life, there would be literally millions of civilizations out there.
If an ancient man saw planes two thousand years ago He would've thought they were birds Or angels from another world Or messengers from other planets.
