Galaxy And Planets Quotes & Sayings

We inhabit a universe where atoms are made in the centers of stars; where each second a thousand suns are born; where life is sparked by sunlight and lightning in the airs and waters of youthful planets; where the raw material for biological evolution is sometimes made by the explosion of a star halfway across the Milky Way; where a thing as beautiful as a galaxy is formed a hundred billion times - a Cosmos of quasars and quarks, snowflakes and fireflies, where there may be black holes and other universe and extraterrestrial civilizations whose radio messages are at this moment reaching the Earth. How pallid by comparison are the pretensions of superstition and pseudoscience; how important it is for us to pursue and understand science, that characteristically human endeavor. — Carl Sagan

The apparent incompatibility between the abundance of habitable planets in our Galaxy and the lack of extraterrestrial visitors, known as the Fermi paradox, suggest the existence of what Hanson calls a "Great Filter," an evolutionary/technological roadblock somewhere along the developmental path from nonliving matter to space-colonizing life. If we discover independently evolved primitive life in our Solar System, this would suggest that primitive life is not rare, and that the roadblock lies after our current human stage of development-perhaps because assumption 1 is false, or because almost all advanced civilizations self-destruct before they are able to colonize. I'm therefore crossing my fingers that all searches for life on Mars and elsewhere find nothing: this is consistent with the scenario where primitive life is rare but we humans got lucky, so that we have the roadblock behind us and have extraordinary future potential. — Max Tegmark

Harvard astronomer Owen Gingerich (2006) reported that there are more than 100 billion galaxies. One of these, our own relative speck of a galaxy, has a few hundred billion stars, many of which, like our Sun-star, are circled by planets. On the scale of outer space, we are less than a single grain of sand on all the oceans' beaches, and our lifetime but a relative nanosecond. — David G. Myers

We search for life on others planets and in other regions of our galaxy. Meanwhile we destroy and ignore the other life on this planet. — Anthony D. Williams

It is a very naive view to think that the resources and conditions on earth would last forever. Our race has to take necessary steps to be able to develop the technology necessary to live on other planets and moons and to reach to farther corners of the galaxy. — Anousheh Ansari

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. — Jodie Foster

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. — Arthur C. Clarke

I gaze out, to the stars. I remember the first time I saw real stars, through the hatch window. They were beautiful then, but now, seeing them here, all around me, beautiful feels like an inadequate word. I see the stars as a part of the universe, and having spent my life behind walls, suddenly having none fills me with both awe and terror. Emotion courses through my veins, choking me. I feel so insignificant, a tiny speck surrounded by a million stars.
A million suns.
Centuries away is Sol. Circling around it is Sol-Earth, the planet Amy came from. And one of these other stars is the Centauri binary system, where the new planet spins, waiting for us.
And here we are, in the middle, surrounded by a sea of stars.
Any of them could hold a planet. Any of them could hold a home.
But all of them are out of reach. — Beth Revis

Data from orbiting telescopes like NASA's Kepler Mission hint that the tally of habitable planets in our galaxy is many billion. If E.T.'s not out there, then Earth is more than merely special - it's some sort of miracle. — Seth Shostak

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. — Seth Shostak

I have a vision of a Galaxy overrun by mankind from Core to rim. Of four hundred billion stars each enslaved to the rhythm of Earth's day, Earth's year. I have a vision of a trillion planets pulsing to the beat of a human heart. — Stephen Baxter

The galaxy is changing. Planets are falling out of alignment. — R.J. Palacio

There is a point of view among astronomical researchers that is generally referred to as the Principle of Mediocrity ... If the Sun and its retinue of worlds is only one system among many, then many other systems will be like ours: home to life. Indeed, to the extent that this is true, we should be prepared for the possibility that, even in the Milky Way galaxy, billions of planets may be carpeted by the dirty, nasty business known as life. — Seth Shostak

The human mind is grown inside a 0.0013 cubic meters crystalline calcium phosphate box on the 149 million km2 rocky surface of a 510 million km2 planet that is falling in a straight line over curved space at 108,000 kilometres per hour inside the gravity well of a 6 trillion km2 star on a 250 million year sojourn around the centre of a galaxy containing some 400 billion stars and trillions of planets and moons. The immediate solar system appears to end at the Kuiper Belt, its outer edge a mind-stunning 7 billion kilometres away, yet the outermost reach of the Heliosphere is still another 5 billion kilometres further out. The furthest object, however, within the Sun's gravity well, Sedna, marks the solar system's diameter to in fact be a sense-jarring 287 billion kilometres in length. — John Zande

Earlier generations of stars in the galaxy could well have had planets. But really, there was only hydrogen and helium to work with, so they'd all be gas giants and not small, rocky planets. — Jill Tarter

WE ARE MADE OF STARDUST, THE SCIENTISTS SAY - THE iron in our blood, the calcium in our bones, and the chlorine in our skin forged in the furnaces of ancient stars whose explosions scattered the elements across the galaxy. From the ashes grew new stars, and around one of them, a system of planets and asteroids and moons. A cluster of dust coalesced to form the earth, and life emerged from the detritus of eight-billion-year-old deaths. — Rachel Held Evans

Of all the Programmers' planets, ours is the supercomputing golden child, the world that inexplicably provides enough power to light up the galaxy. — David Eagleman

In our galaxy alone, we think there are about 10 billion Earth-like planets orbiting stars like our Sun. Given that there are hundreds of billions of galaxies, the odds are strong that life has evolved somewhere else. To think that we are the only life in the universe is just an extension of the same arrogance that made us think we were the center of it all. — Chris Hadfield

It has been estimated that there are between 1 billion and 30 billion planets in our galaxy, and about 100 billion galaxies in the universe. Knocking a few noughts off for reasons of ordinary prudence, a billion billion is a conservative estimate of the number of available planets in the universe. Now, suppose the origin of life, the spontaneous arising of something equivalent to DNA, really was a quite staggeringly improbable event. Suppose it was so improbable as to occur on only one in a billion planets. A grant-giving body would laugh at any chemist who admitted that the chance of his proposed research succeeding was only one in a hundred. But here we are talking about odds of one in a billion. And yet . . . even with such absurdly long odds, life will still have arisen on a billion planets - of which Earth, of course, is one. — Richard Dawkins

Tom's theory of why human beings had yet to receive any message from extraterrestrial intelligences was that all civilizations, without exception, blew themselves up almost as soon as they were able to get a message out, never lasting more than a few decades in a galaxy whose age was billions; blinking in and out of existence so fast that, even if the galaxy abounded with earthlike planets, the chances of one civilization sticking around to get a message from another were vanishingly low, because it was too damned easy to split the atom. — Jonathan Franzen

For the first billion years, the universe continued to expand and cool as matter gravitated into the massive concentrations we call galaxies. Nearly a hundred billion of them formed, each containing hundreds of billions of stars that undergo thermonuclear fusion in their cores. Those stars with more than about ten times the mass of the Sun achieve sufficient pressure and temperature in their cores to manufacture dozens of elements heavier than hydrogen, including those that compose planets and whatever life may thrive upon them. These elements would be stunningly useless were they to remain where they formed. But high-mass stars fortuitously explode, scattering their chemically enriched guts throughout the galaxy. After nine billion years of such enrichment, in an undistinguished part of the universe (the outskirts of the Virgo Supercluster) in an undistinguished galaxy (the Milky Way) in an undistinguished region (the Orion Arm), an undistinguished star (the Sun) was born. The — Neil DeGrasse Tyson

To say that the planet is overpopulated with billions of humans is one perspective. To say that there are many planets in our galaxy that should be colonized is another perspective. — Robin Sacredfire

A time will come when men will stretch out their eyes. They should see planets like our Earth. — Christopher Wren

We only recently figured out the origin of our own moon. And we have some idea of how the Sun and Earth formed, but that's only because modern telescopes empower us to see other stars and planets freshly hatched within gas clouds across the galaxy. As for the origin of life itself, the transition from inanimate molecules to what any of us would call life remains one of the great frontiers of biology. — Neil DeGrasse Tyson

I'll never understand why some people can't just let others live their lives, you know," Danial said. "You don't have to understand. You don't have to agree. Just leave people alone. When I look at the moon and planets and stars, all that narrow-mindedness and hate seem so petty. The universe is such a big place. One hundred thousand light years just from one end of the Milky Way to the other. One hundred. Thousand. Light years. In the time it's taken for light to travel from one end of our galaxy to the other, thousands of generations have passed. It really makes you realize how small we are, doesn't it? How short our time on earth is. — J.H. Trumble

There was an image in my mind - an expectation of what it would be like when I finally gave myself fully to a man. It wasn't like this. It was always at night with candles flickering lazily, music filling the air with a sexy melody, and maybe a bubble bath. But no. It was infinitely better, and there was no froo froo, stereotypical scene that played out.
It was incredible.
Brilliant.
Amazing.
Indescribable, really. Like all the planets in the galaxy aligned for a perfect moment in time. As if this was the beginning of time. From now until the rest of eternity, everything finally had meaning. — Laura Kreitzer

I should say we know that there are many, many other Earths out there. We're almost certain that there will be upwards of a billion Earth-like planets in our galaxy alone, so there is no lack of real estate where life might happen, but what we don't know is how likely it is given the real estate, given a wonderful pristine planet like Earth how likely is it that life will pop up inhabited? We don't know the answer to that. — Paul Davies

Then everything was normal again, except that the liner was speeding for the planet Krim at something more than thirty times the speed of light. Normality extended through all the galaxy so far inhabited by men. There were worlds on which there was peace, and worlds on which there was tumult. There were busy, zestful young worlds, and languid, weary old ones. From the Near Rim to the farthest of occupied systems, planets circled their suns, and men lived on them, and every man took himself seriously and did not quite believe that the universe had existed before he was born or would long survive his loss. Time passed. Comets let out vast streamers like bridal veils and swept toward and around their suns. Some of them - one in ten thousand, or twenty - were possibly seen by human eyes. The liner bearing Hoddan sped through the void. In time it made a landfall on the Planet Krim. — Murray Leinster

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 — Francis Collins

Somewhere in the cosmos, he said, along with all the planets inhabited by humanoids, reptiloids, fishoids, walking treeoids and superintelligent shades of the color blue, there was also a planet entirely given over to ballpoint life forms. And it was to this planet that unattended ballpoints would make their way, slipping away quietly through wormholes in space to a world where they knew they could enjoy a uniquely ballpointoid lifestyle, responding to highly ballpoint-oriented stimuli, and generally leading the ballpoint equivalent of the good life.
And as theories go this was all very fine and pleasant until Veet Voojagig suddenly claimed to have found this planet, and to have worked there for a while driving a limousine for a family of cheap green retractables, whereupon he was aken away, locked up, wrote a book and was finally sent into tax exile, which is the usual fate reserved for those who are determined to make fools of themselves in public. — Douglas Adams

The math is dead simple: it seems that the frequency of planets able to support life is roughly one percent. In other words, a billion or more such worlds exist in our galaxy alone. That's a lot of acreage, and it takes industrial-strength credulity to believe it's all bleakly barren. — Seth Shostak

Life on the planet and in our galaxy is so complex, I don't hope to have any substantial effect in it, but if I can touch a few people deep in their psyche, by making my personal subjective journey concrete for others, then I am very happy. — Roger Ballen

Recent results from astronomers who study the occasional gravitational lensing of unknown worlds by intervening stars suggest that orphan planets could be at least as numerous as the stars. In other words, there could be hundreds of billions of orphan worlds shuffling through our galaxy. — Seth Shostak

We can trace the elements. They were forged in the centers of high-mass stars that went unstable at the ends of their lives, they exploded, scattered their enriched contents across the galaxy, sprinkled into gas clouds that then collapsed and formed stars and planets and life. — Neil DeGrasse Tyson

If we're thinking about old civilizations, those that formed a long time ago and there were stars and planets around long before Earth even existed, then these are going to be towards the center of the galaxy. That is the place to look if you think there are ancient civilizations that have made beacons or some other way of attracting our attention. — Paul Davies

where hyperspatial engineers sucked matter through white holes in space to form it into dream planets - gold planets, platinum planets, soft rubber planets with lots of earthquakes - all lovingly made to meet the exacting standards that the Galaxy's richest men naturally came to expect. — Douglas Adams

Hamlet misspoke, Strawl decided. It is consciousness that makes cowards of us all, not conscience. Right and wrong are venomless when compared to the simple awareness of being alive. The knowledge that existence can equal something past the sum of our circulation and digestion, that those corporeal purposes serve a galaxy of space between a man's ears, whose suns and planets obey his own peculiar science, but one in which he alone recognizes the order, and only in glimpses, epiphanies that melt before he can speak or even think them--and the knowledge even this distant self is not his possession but belongs to others weighing and judging the dim and distant light he emits. — Bruce Holbert

After 7 or 8 billion years of such enrichment, an undistinguished star (the Sun) was born in an undistinguished region (the Orion arm) of an undistinguished galaxy (the Milky Way) in an undistinguished part of the universe (the outskirts of the Virgo supercluster). The gas cloud from which the Sun formed contained a sufficient supply of heavy elements to spawn a few planets, thousands of asteroids, and billions of comets. — Neil DeGrasse Tyson

You're not just looking up into a curtain of black. You're looking into the eye of the universe. Stare for a while and you start to realize -- on a deep, gut level -- that the moon is a giant rock circling us in space. The sun is a violent, fusion-fueled ball of plasma and gas millions of miles away that destroyed the atmospheres of all of the inner planets (including Mars, which is farther away from it than we are) and would do the same to ours if we weren't lucky enough to have a magnetic field that diverts the solar wind. The cute little pinpricks of light you see out there are other giant, explosive, incredibly pissed-off balls of gas floating in an infinite void, most of which are far more impressive than our puny sun. And that smear of milky white through the sky? That's the center of our own galaxy -- a gigantic pinwheel circling a supermassive black hole like floating detritus around the vortex of a flushing toilet. — Johnny B. Truant

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. — Michio Kaku
