Quotes About Galaxies

We are made out of stardust. The iron in the hemoglobin molecules in the blood in your right hand came from a star that blew up 8 billion years ago. The iron in your left hand came from another star.

It is our firm belief that we shall one day learn the plan of the entire multiverse and travel at will from Sphere to Sphere, from realm to realm, from world to world, travel through the great clouds of shifting, multicoloured stars, the tumbling planets in all their millions, through galaxies that swarm like gnats in a summer garden, and rivers of light–glory beyond glory–pathways of moonbeams between the roaming stars.

There is actually a certain value in not finding anything,' he said. 'It helps cosmologists to work out the rate at which galaxies are evolving. It's one of those rare areas where the absence of evidence is evidence.

galaxies of the universe are racing away from us, but that they are doing so at a rate that is accelerating.

Vesto Slipher, of the Lowell Observatory in Arizona, was the first person to notice that distant galaxies appeared to be moving away from us—evidence that the universe was not, as everyone had long assumed, static.

Astronomers today believe there are perhaps 140 billion galaxies in the visible universe.

The red shift gives the speed at which galaxies are retiring, but doesn't tell us how far away they are to begin with.

when we peer into the distance some of the galaxies we see may simply be reflections, ghost images created by rebounded light.

It may seem topsy-turvy that cosmologists can speak confidently about galaxies billions of light years away, whereas theories of diet and child rearing – issues that everyone cares about – are still tentative and controversial

Pedacinho por pedacinho, desliguei-a. Vi luzes se apagando uma após a outra. Observei o espaço Cansino retroceder. Primeiro sumiram as galáxias, logo em seguida as estrelas, e então: trevas, somente o fundo das minhas pálpebras.

As the Greeks have created the Olympus based upon their own image and resemblance, we have created Gotham City and Metropolis and all these galaxies so similar to the corporate world, manipulative, ruthless and well paid, that conceived them.

Astronomers can look back in time. We can look at things as they used to be. We have an idea there was a Big Bang explosion 13.7 billion years ago. We have a story of how galaxies and stars were made. It's an amazing story.

why doesn't the universe spin?

Los agujeros negros en el centro de las dos galaxias ejecutarán una danza de la muerte antes de colisionar y fusionarse finalmente.

Since photographs of galaxies only show the beautiful swirling mass of stars, whatever is holding the mass together must not interact with light—it must be invisible.

If the universe is dense enough, then there is enough matter and gravity to attract the distant galaxies and reverse the expansion, so that the Big Crunch becomes a realistic possibility. If the universe lacks sufficient mass, then there is not enough gravity to reverse the expansion and the universe goes into a Big Freeze. The critical density separating these two scenarios is roughly six hydrogen atoms per cubic meter.

The very existence of galaxies, stars, planets, and life itself derives from microscopic quantum uncertainty amplified by inflationary expansion.

The human body is a machine, a system of organic chemicals, fluid conduits, electrical impulses; a government is likewise a machine of interacting societies, laws, cultures, rewards and punishments, patterns of behavior. Ultimately, the universe itself is a machine, planets around suns, stars gathered into clusters, clusters and other suns forming entire galaxies.… Our job is to keep the machinery functioning.

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.

We are all star stuff.

We are all stardust

Except for hydrogen, all the atoms that make each of us up—the iron in our blood, the calcium in our bones, the carbon in our brains—were manufactured in red giant stars thousands of light-years away in space and billions of years ago in time. We are, as I like to say, starstuff.

The immense distances to the stars and the galaxies mean that we see everything in space in the past, some as they were before the Earth came to be. Telescopes are time machines.

The study of the galaxies reveals a universal order and beauty. It also shows us chaotic violence on a scale hitherto undreamed of. That we live in a universe which permits life is remarkable. That we live in one which destroys galaxies and stars and worlds is also remarkable. The universe seems neither benign nor hostile, merely indifferent to the concerns of such puny creatures as we.
