Famous Neil deGrasse Tyson Quotes

“There's no greater sign of the failure of the American educational system than the extent to which Americans are distracted by the possibility that Earth might end on December 21, 2012. It's a profound absence of awareness of the laws of physics and how nature works. So they're missing some science classes in their training in high school or in college that would empower them to understand and to judge when someone else is basically just full of it. Science is like an inoculation against charlatans who would have you believe whatever it is they tell you.”

“If an alien lands on your front lawn and extends an appendage as a gesture of greeting, before you get friendly, toss it an eightball. If the appendage explodes, then the alien was probably made of antimatter. If not, then you can proceed to take it to your leader.”

“You ask people, do you pray to [a person or] God. If you say yes to that, you're religious by, presumably, anybody's standards of your conduct. And it's the yes to that question that applies to 40% of scientists. So, there're plenty of atheists who are scientists or not scientists. There maybe a conflict but many people in this country coexist in both worlds.”

“I don't have an issue with what you do in the church but I'm going to be up in your face if you're going to knock on my science classroom and tell me I got to teach what you're teaching in your Sunday school. That's when we're going to fight... There's no tradition of scientists knocking down the Sunday school door, telling the preacher 'that might not necessarily be true.' That's never happened. There are no scientists picketing out front of churches. There's been this coexistence forever, so to have religious communities knocking down the science door, there's something wrong there.”

“In whatever you choose to do, do it because it's hard, not because it's easy. Math and physics and astrophysics are hard. For every hard thing you accomplish, fewer other people are out there doing the same thing as you. That's what doing something hard means. And in the limit of this, everyone beats a path to your door because you're the only one around who understands the impossible concept or who solves the unsolvable problem.”

“As religion is now practiced and science is now practiced, there is no intersection between the two. That is for certain. And it’s not for want of trying. Over the centuries, many people—theologians as well scientists - have tried to explore points of intersection. And anytime anyone has declared that harmony has risen up, it is the consequence of religion acquiescing to scientific discovery. In every single case.”

“Do you realize that the 850 billion dollar bank bailout, that sum of money is greater than the entire 50 year running budget of NASA. And so when someone says, 'We don't have enough money for this space probe.' No, it's not that you don't have enough money. It's that the distribution of money that you're spending is warped in some way that you are removing the only thing that gives people something to dream about tomorrow.”

“Our entire universe emerged from a point smaller than a single atom. Space itself exploded in a cosmic fire, launching the expansion of the universe and giving birth to all the energy and all the matter we know today. I know that sounds crazy, but there’s strong observational evidence to support the Big Bang theory. And it includes the amount of helium in the cosmos and the glow of radio waves left over from the explosion.”

“Some claim evolution is just a theory. As if it were merely an opinion. The theory of evolution, like the theory of gravity, is a scientific fact. Evolution really happened. Accepting our kinship with all life on Earth is not only solid science. In my view, it’s also a soaring spiritual experience.”

“Artificial selection turned the wolf into the shepherd, and the wild grasses into wheat and corn. In fact, almost every plant and animal that we eat today was bred from a wild, less edible ancestor. If artificial selection can work such profound changes in only ten or fifteen thousand years, what can natural selection do operating over billions of years? The answer is all the beauty and diversity of life.”

“Stars die and reborn […] They get so hot that the nuclei of the atoms fuse together deep within them to make the oxygen we breathe, the carbon in our muscles, the calcium in our bones, the iron in our blood. All was cooked in the fiery hearts of long vanished stars. … The cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself.”

“Lots of people think, well, we're humans; we're the most intelligent and accomplished species; we're in charge. Bacteria may have a different outlook: more bacteria live and work in one linear centimeter of your lower colon than all the humans who have ever lived. That's what's going on in your digestive tract right now. Are we in charge, or are we simply hosts for bacteria? It all depends on your outlook.”

“Creativity is seeing what everyone else sees, but then thinking a new thought that has never been thought before and expressing it somehow. It could be with art, a sculpture, music or even in science. The difference, however, between scientific creativity and any other kind of creativity, is that no matter how long you wait, no one else will ever compose "Beethoven's Ninth Symphony" except for Beethoven. No matter what you do, no one else will paint Van Gogh's "Starry Night." Only Van Gogh could do that because it came from his creativity.”
