Famous Neil deGrasse Tyson Quotes

“I don't want students who could make the next major breakthrough in renewable energy sources or space travel to have been taught that anything they don't understand, and that nobody yet understands, is divinely constructed and therefore beyond their intellectual capacity. The day that happens, Americans will just sit in awe of what we don't understand, while we watch the rest of the world boldly go where no mortal has gone before.”

“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.”

“When provoked, the itsy-bitsy invertebrates known as tardigrades can suspend their metabolism. In that state, they can survive temperatures of... 73 K for days on end, making them hardy enough to endure being stranded on Neptune. So the next time you need space travelers with the right stuff, you might want to choose yeast and tardigrades, and leave your astronauts, cosmonauts, and taikonauts at home.”

“Apart from the obvious advantages of having ice to melt, filter, then drink, you can also break apart the water's hydrogen from its oxygen. Use the hydrogen and some of the oxygen as active ingredients in rocket fuel and keep the rest of the oxygen for breathing. And in your spare time between space missions, you can always go ice skating on the frozen lake created with the extracted water.”

“We should not measure our space-faring era by where footprints have been laid.... We should measure our era by how many people take no notice at all. A legacy rises to become culture only when its elements are so common that they no longer attract comment.”

“They all knew the mothership was coming, they all knew it was a flying saucer, they all knew it came from another planet through the vacuum of space. And so what do they do, to the left of that monument? They set up runway lights. And I'm thinking, if you could travel through the vacuum of space, you don't need runway lights. Runway lights are if you're using air for lift. Aliens would not need air for lift.”

“Trillions of years into the future, when all stars are gone...all parts of the cosmos will cool to the same temperature as the ever-cooling background. At that time, space travel will no longer provide refuge because even Hell will have frozen over. We may then declare that the universe has died-not with a bang, but with a whimper.”

“FM signals and those of broadcast television...travel out to space at the speed of light. Any eavesdropping alien civilization will know all about our TV programs (probably a bad thing), will hear all our FM music (probably a good thing), and know nothing of the politics of AM talk-show hosts (probably a safe thing).”

“Astrophysicists perfected navigation. We perfected all these things that matter to the power of nations manifest on the world stage. So we want to go into space. That's the new high ground, right? We care about multispectral imaging of things. Well, that's what reconnaissance wants to do. So our expertise has been in bed with national security needs forever. So maybe, secretly, that's why they keep us employed.”

“I've said multiple times that the world's first trillionaire is going to be the person who exploits the resources of asteroids, the natural resources that are rare on earth and common on selected asteroids. So there are many different reasons you might want to go into space. You might want to spend your honeymoon on the far side of the moon.”

“To view space as, "Well, let's go to Mars now," or "Let's do this now," maybe we should rethink of space as our backyard and have a suite of launch vehicles that can enable any ambition a person has regarding space. It's the same way you can go to buy a car: I want to go offroading, I'll buy this model. I'm a city driver, that's this model. I want to use less fuel, well, that's this model. They're not selling you one car, you have options. So when I think of space, I think of having options.”

“If NASA were advancing a space frontier there would be challenges you've never seen before. You have to be creative and you have to patent some new idea. You get to Mars...well, how do we get the water from the soil? I gotta invent a new device that will do that. And the carbon dioxide in the atmosphere, how can we use that? Can we breathe the oxygen from the carbon dioxide?”

“When NASA makes discoveries they are profound and they make headlines, everyone takes notice. It drives dialogue and, today, it would drive the blogosphere. It would drive the projects the kids do in school. So you wouldn't even need programs to try and stimulate curiosity. You wouldn't need programs to try to convince people that science literacy is good. Because they're going to want to participate on this epic adventure that we call space exploration.”
