Universe Scale Quotes

Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is.

We live in a vast and awesome universe in which, daily, suns are made and worlds destroyed, where humanity clings to an obscure clod of rock.

How can a speck of a universe be physically identical to the great expanse we view in the heavens above?

Even these stars, which seem so numerous, are as sand, as dust - or less than dust - in the enormity of the space in which there is nothing.

Staring at the stars was like staring backward in time, since some stars are so far away that their light takes millions of years just to reach us. That we see stars not as they look now, but as they were when dinosaurs roamed the earth. The whole concept just struck me as…amazing somehow.

You see billions and billions of stars and recognize that you know some of those have planets, too, and maybe there's life out there, and this is just one of billions of galaxies... and so it gives you this huge perspective of how far we potentially have to go for real exploration.

In the visible world, the Milky Way is a tiny fragment; within this fragment, the solar system is an infinitesimal speck, and of this speck our planet is a microscopic dot. On this dot, tiny lumps of impure carbon and water, of complicated structure, with somewhat unusual physical and chemical properties, crawl about for a few years, until they are dissolved again into the elements of which they are compounded.

I went to the librarian and asked for a book about stars.... And the answer was stunning. It was that the Sun was a star but really close. The stars were suns, but so far away they were just little points of light.... The scale of the universe suddenly opened up to me. It was a kind of religious experience. There was a magnificence to it, a grandeur, a scale which has never left me. Never ever left me.

We are just strings of quarks living in a suburb of the local density maximum of the universe.

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.

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.

Until the 1990s, there were few reliable observations about movement at the scale of the entire universe, which is the only scale dark energy effects. So dark energy could not be seen until we could measure things very, very far away.

There comes a point in your life when you realize how quickly time goes by, and how quickly it has gone. Then it really speeds up exponentially. With that, I think you start to put a lot of things into context; you start to see how huge the world is, and really, the universe.

I think there is something very consoling in feeling lost in space but also feeling grounded, and seeing that all of this is part of a bigger clockwork

Our galaxy, the Milky Way, is one of 50 or 100 billion other galaxies in the universe. And with every step, every window that modern astrophysics has opened to our mind, the person who wants to feel like they're the center of everything ends up shrinking.

The large-scale homogeneity of the universe makes it very difficult to believe that the structure of the universe is determined by anything so peripheral as some complicated molecular structure on a minor planet orbiting a very average star in the outer suburbs of a fairly typical galaxy.

There are strong reasons for believing that space goes on beyond the limits of our observational horizon. There are strong reasons because if you look in opposite directions, conditions are the same to within one part in 100,000. So if we are part of some finite structure then, if the gradient is so shallow, it is likely to go on much further.

If the whole earth is infinitely small in comparison with the sphere of the stars, what is man compared with all these created beings!

As our mother-earth is a mere speck in the sunbeam in the illimitable universe, so man himself is but a tiny grain of protoplasm in the perishable framework of organic nature.

The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small.

This truth within thy mind rehearse, That in a boundless universe Is boundless better, boundless worse.
