Neil deGrasse Tyson Science Quotations

Every account of a higher power that I've seen described, of all religions that I've seen, include many statements with regard to the benevolence of that power. When I look at the universe and all the ways the universe wants to kill us, I find it hard to reconcile that with statements of beneficence.

It was unthinkable not long ago that a biologist or paleontologist would be at the same conference as an astrophysicist. Now we have accumulated so much data in each of these branches of science as it relates to origins that we have learned that no one discipline can answer questions of origins alone.

Let's say intelligence is your ability to compose poetry, symphonies, do art, math and science. Chimps can't do any of that, yet we share 99 percent DNA. Everything that we are, that distinguishes us from chimps, emerges from that one-percent difference.

If God is the mystery of the universe, these mysteries, we're tackling these mysteries one by one. If you're going to stay religious at the end of the conversation, God has to mean more to you than just where science has yet to tread.

Part of what it is to be scientifically-literate, it's not simply, 'Do you know what DNA is? Or what the Big Bang is?' That's an aspect of science literacy. The biggest part of it is do you know how to think about information that's presented in front of you.

Ever since the Industrial Revolution, investments in science and technology have proved to be reliable engines of economic growth. If homegrown interest in those fields is not regenerated soon, the comfortable lifestyle to which Americans have become accustomed will draw to a rapid close.

Carl Sagan spoke fluently between biology and geology and astrophysics and physics. If you move fluently across those boundaries, you realize that science is everywhere; science is not something you can step around or sweep under the rug.

'Cosmos' wouldn't deserve its place in primetime evening network television were it not a landscape on which compelling stories were told. People, when they watch TV in the evening, want to see stories, and science simply tells the best stories.

It's actually the minority of religious people who rejects science or feel threatened by it or want to sort of undo or restrict the... where science can go. The rest, you know, are just fine with science. And it has been that way ever since the beginning.

The idea that science is just some luxury that you'll get around to if you can afford it is regressive to any future a country might dream for itself.

As history has shown, pure science research ultimately ends up applying to something. We just don't know it at the time.

You can't train kids in a world where adults have no concept of what science literacy is. The adults are gonna squash the creativity that would manifest itself, because they're clueless about what it and why it matters. But science can always benefit from the more brains there are that are thinking about it - but that's true for any field.

Science is an enterprise that should be cherished as an activity of the free human mind. Because it transforms who we are, how we live, and it gives us an understanding of our place in the universe.

Most religious people in America fully embrace science. So the argument that religion has some issue with science applies to a small fraction of those who declare that they are religious. They just happen to be a very vocal fraction, so you got the impression that there are more of them than there actually is.

My parents didn't know much science; in fact, they didn't know science at all. But they could recognize a science book when they saw it, and they spent a lot of time at bookstores, combing the remainder tables for science books to buy for me. I had one of the biggest libraries of any kid in school, built on books that cost 50 cents or a dollar.

I was an aspiring astrophysicist, and that's how I defined myself, not by my skin color. People didn't treat me as someone with science ambitions. They treated me as someone they thought was going to mug them, or who was a shoplifter.

The partisanship surrounding space exploration and the retrenching of U.S. space policy are part of a more general trend: the decline of science in the United States. As its interest in science wanes, the country loses ground to the rest of the industrialized world in every measure of technological proficiency.

I'm on a crusade to get movie directors to get their science right because, more often than they believe, the science is more extraordinary than anything they can invent.

I'm often asked by parents what advice can I give them to help get kids interested in science? And I have only one bit of advice. Get out of their way. Kids are born curious. Period.

Innovations in science and technology are the engines of the 21st-century economy; if you care about the wealth and health of your nation tomorrow, then you'd better rethink how you allocate taxes to fund science. The federal budget needs to recognize this.

I like to believe that science is becoming mainstream. It should have never been something that sort of geeky people do and no one else thinks about. Whether or not, it will always be what geeky people do. It should, as a minimum, be what everybody thinks about because science is all around us.

In nature, when you conduct science, it is the natural world that is the ultimate decider in what is true and what is not.

I claim that all those who think they can cherry-pick science simply don't understand how science works. That's what I claim. And if they did, they'd be less prone to just assert that somehow scientists are clueless.

It is astonishing to realize that until Galileo performed his experiments on the acceleration of gravity in the early seventeenth century, nobody questioned Aristotle's falling balls. Nobody said, Show Me!

A television advertisement must illustrate the scientific method to substantiate any claim.... That is why stains are lifted, ring-around-the-collar is removed, paper towels become soaked, excess stomach acid is absorbed, and headaches go away-all during the commercial.

We fail in even the simplest of all scientific observations-nobody looks up anymore.

I didn't even know there were stars to look at to not see. If you don't know that they're there, you don't know that you're missing them.

For your own safety, do not ever tell an astrophysicist, I hope all your stars are twinkling.

And I don't care what else anyone has ever told you, the Sun is white, not yellow. Human color perception is a complicated business, but if the Sun were yellow, like a yellow lightbulb, then white stuff such as snow would reflect this light and appear yellow-a snow condition confirmed to happen only near fire hydrants.

There is a theorem that colloquially translates, You cannot comb the hair on a bowling ball. ... Clearly, none of these mathematicians had Afros, because to comb an Afro is to pick it straight away from the scalp. If bowling balls had Afros, then yes, they could be combed without violation of mathematical theorems.

He invited people to sign a petition that demanded either strict control of, or a total ban on, dihydrogen monoxide.... Yes, 86 percent of the passersby voted to ban water (H2O) from the environment. Maybe that's what really happened to all the water on Mars.

People like it when they understand something that they previously thought they couldn't understand. It's a sense of empowerment.

Our five senses are faulty data-taking devices, and they need help.

The value of science is not simply what the next model of the iPod you will buy next week, but its real value comes about when it's time to distinguish reality from everything else. And to be scientifically literate is to be trained in what it is, to recognize your own frailty as a data-taking device.

The past is another planet.

Scientists are human. We have our blind spots and prejudices. Science is a mechanism designed to ferret them out. Problem is we aren't always faithful to the core values of science.

Feeling a little small? Well, in the context of the cosmos, we are small.

What scientists want next is a thorough comparison of what we and exosolar planets and vagabonds look like. Only in this way will we know whether our home life is normal or whether we live in a dysfunctional solar family.

But my vote for Venus's most peculiar feature is the presence of craters that are all relatively young and uniformly distributed over its surface. This innocuous-sounding feature implicates a single planetwide catastrophe that reset the cratering clock... turning Venus's entire surface into the American automotive dream-a totally paved planet.

Note, however, that you cannot simply add temperatures the way you can add volumes or weights. Two people in bed, each with body temperatures of 98.6 degrees Fahrenheit, do not normally create a 197.2 degree under-the-cover oven.

Your center of mass is a place you cannot visit but you always carry with you. Like memories, it is part of life's baggage.

Publicly and among themselves biologists rightly celebrate the diversity of life on Earth... At the end of the day, however, their confession is heard by no one: they work with a single scientific sample-life on Earth.

This influential, yet controversial idea requires that the mixture of species on Earth at any moment acts as a collective organism that continuously (yet unwittingly) tunes Earth's atmospheric composition and climate to promote the presence of life... But I'd bet there are some dead Martians and Venusians who advanced the same theory about their own planets a billion years ago.

The telescope... is a conduit to the cosmos.

There are photons that have been traveling for 30,000 years, and I'm... snatching them from this journey and planting them into my digital detector. And then I started feeling bad for the photon, and I said maybe it wanted to continue but I got in its way. But then I said, no, those are probably happier photons than the one that slammed into the mountainside that will go unanalyzed and will not contribute to the depth of our understanding of the universe.

Photons are accurately and legitimately described as waves and particles at the same time. They are genuine wavicles.

If there were biologists among the extremophiles organisms that live in extreme conditions, they would surely classify themselves as normal and any life that thrived in room temperature as an extremophile.

UV is bad for molecules because its high energy breaks the bonds between a molecule's constituent atoms. That's why UV is bad for you, too: it's always best to avoid things that decompose the molecules of your flesh.

I want to put on the table, not why 85% of the members of the National Academy of Sciences reject God, I want to know why 15% of the National Academy don’t.

A common way to compute density is, of course, to take the ratio of an object's mass to its volume. But other types of densities exist, such as the resistance of somebody's brain to the imparting of common sense....

So while you're getting ripped apart head to toe as you fall into a black hole, you will also extrude through the fabric of space and time, like toothpaste squeezed through a tube. To all the words in the English language that describe ways to die (e.g., homicide, suicide, electrocution, suffocation, starvation) we add the term spaghettification.

To achieve this density of a neutron star at home, just cram a herd of 50 million elephants into the volume of a thimble.

The iron from that meteorite and the iron from your blood have common origin in the core of a star.

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.

Deep in the world of atomic nuclei, life is not always tranquil.

Gamma rays are the sort of radiation you should avoid. Want proof? Just remember how the comic strip character "The Hulk" became big, green, and ugly.

I suppose I can live with missing decimals, missing floors to tall buildings, and floors that are named instead of numbered. A more serious problem is the limited capacity of the human mind to grasp the relative magnitudes of large numbers. Counting at the rate of one number per second...to count to a trillion takes 32,000 years, which is as much time as has elapsed since people first drew on cave walls.

Last I checked, Bill Gates was worth $50 billion. If the average employed adult, who is walking in a hurry, will pick up a quarter from the sidewalk, but not a dime, then the corresponding amount of money given their relative wealth that Bill Gates would ignore if he saw it lying on the street is $25,000.

You can make a stack high enough to reach the moon and back, and only then will you have used your 100 billion hamburgers. This is terrifying news to cows.

The more I learn about the universe, the less convinced I am that there's any sort of benevolent force that has anything to do with it, at all.

My view is that if your philosophy is not unsettled daily then you are blind to all the universe has to offer.

So what is true for life itself is no less true for the universe: knowing where you came from is no less important than knowing where you are going.

One thing in life is for certain, the more profoundly baffled you have been in your life, the more open your mind becomes to new ideas.

Not enough of our society is trained how to understand and interpret quantitative information. This activity is a centerpiece of science literacy to which we should all strive-the future health, wealth, and security of our democracy depend on it. Until that is achieved, we are at risk of making under-informed decisions that affect ourselves, our communities, our country, and even the world.

While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.

And extracting one molecule's signature in spectral analysis from the rest of the signatures is hard work, sort of like picking out the sound of your toddler's voice in a roomful of screaming children during playtime. It's hard, but you can do it.

The good thing about science is that it's true whether or not you believe in it.
