galactic scale Quotes

The total number of stars in the Universe is larger than all the grains of sand on all the beaches of the planet Earth.

We live on a hunk of rock and metal that circles a humdrum star that is one of 400 billion other stars that make up the Milky Way Galaxy which is one of billions of other galaxies which make up a universe which may be one of a very large number, perhaps an infinite number, of other universes. That is a perspective on human life and our culture that is well worth pondering.

There are as many atoms in each molecule of your DNA as there are stars in the typical galaxy. This is true for dogs, and bears, and every living thing. We are, each of us, a little universe.

Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.

Whenever you wonder about yourself, look up at the stars swirling around in the heavens and just realize how tiny and puny they are. They're supposed to be gigantic explosions and they're just these insignificant little dots. If you step back from things far enough you realize how important and powerful you are.

The stars are so far, far away!

On a really dark night, you can see between 1,000 and 1,500 stars, and there are millions more that haven't been discovered. It is so easy to think that the world revolves around you, but all you have to do is stare up at the sky to realize it isn't that way at all. -Brian Fitzgerald

For the Earth is only an atom in the universe of worlds.

Kid says to me, "You play baseball? What position? Left out?" and gets a big laugh from the rest of the class. Kid is only one person out of 6.792 billion humans on this planet. This planet is only one-eighth of the solar system, whose sun is one of two billion stars in the Milky Way galaxy. Put it that way, the comment loses it's importance.

How can you look at the galaxy and not feel insignificant?

There are more stars known to exist right now than the total number of all the grains of sand on every beach in the entire world. With those kinds of odds, it would seem downright naive for someone to go to a beach in, say, some out-of-the-way inlet in Baffin Bay, stoop to pick up only one tiny grain of sand, and declare that that grain alone was the only place where life could exist.

Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a distance one upon another, but this action is so slight at great distances that their trajectories are rectilineal; nevertheless, from time to time, two of them may come near enough together to be deviated from their course, like a comet that passed too close to Jupiter. In a word, in the eyes of a giant, to whom our Suns were what our atoms are to us, the Milky Way would only look like a bubble of gas.

We live in a modest system, a galaxy called the Milky Way. If we named every star in the Milky Way and put them in the Hollywood telephone directory and stacked those telephone directories up, we'd have a pile of telephone directories 70 miles high.

There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.

Science has an uncomfortable way of pushing human beings from center stage. In our prescientific stories, humans began as the focal point of Nature, living on an Earth that was the center of the universe. As the origins of the Earth and of mankind were investigated more carefully, it became clear that Nature had other interests beyond people, and the Earth was less central than previously hoped. Humankind was just one branch of the great family of life, and the Earth is a smallish planet orbiting an unexceptional sun quite far out on one arm of a run-of-the-mill spiral galaxy.

The bottom line is, like, one in five stars has at least one planet where life might spring up. That's a fantastically large percentage. That means in our galaxy, there's on the order of tens of billions of Earth-like worlds.

I just believe in a huge universe of billions of miles.

Estimates are that at least 70 per cent of all stars are accompanied by planets, and since the latter can occur in systems rather than as individuals (think of our own solar system), the number of planets in the Milky Way galaxy is of order one trillion.

The universe is a big place. If I was lost up there, how would you ever find me

Astronomy is useful because it raises us above ourselves; it is useful because it is grand; .... It shows us how small is man's body, how great his mind, since his intelligence can embrace the whole of this dazzling immensity, where his body is only an obscure point, and enjoy its silent harmony.

Astronomy taught us our insignificance in Nature.

I watched the night sky with it's countless stars and its moon, and I wondered about the universe and all that had been created, why the stars and the moon rose at night and the sun in the day, how vast it must be, how I could never understand the infinite measure of its size.

Herschel removed the speckled tent-roof from the world and exposed the immeasurable deeps of space, dim-flecked with fleets of colossal suns sailing their billion-leagued remoteness.

This world has many rings, like Saturn, and we live now on the outmost of them all. None can say deliberately that he inhabits thesame sphere, or is contemporary, with the flower which his hands have plucked, and though his feet may seem to crush it, inconceivable spaces and ages separate them, and perchance there is no danger that he will hurt it.

Every star has been set in the sky. We mistakenly think they were put there for us.
