Neil deGrasse Tyson Quotes

Math is the language of the universe. So the more equations you know, the more you can converse with the cosmos.


Do you realize that if you fall into a black hole, you will see the entire future of the Universe unfold in front of you in a matter of moments and you will emerge into another space-time created by the singularity of the black hole you just fell into?


In life and in the universe it’s always best to keep looking up.


If our solar system is not unusual, then there are so many planets in the universe that, for example, they outnumber the sum of all sounds and words ever uttered by every human who has ever lived. To declare that Earth must be the only planet with life in the universe would be inexcusably bigheaded of us.


What are the lessons to be learned from this journey of the mind through the universe? That humans are emotionally fragile, perennially gullible, hopelessly ignorant masters of an insignificantly small speck in the cosmos. Have a nice day.


My only hope is that every other alien civilization isn’t doing exactly what we are doing because then everybody would be listening, nobody would be receiving, and we would collectively conclude that there is no other intelligent life in the universe.


We are star dust in the highest exalted way, called by the universe, reaching out to the universe


The universe has really never made things in ones. The Earth is special and everything else is different? No, we’ve got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it’s one of a hundred billion galaxies. And the universe–maybe it’s countless other universes.


Everything we do understand about the universe – the periodic table of elements, Einstein’s laws, Newton’s laws, all of chemistry, all of biology – that’s 4 percent of the universe. We got to the moon on the 4 percent we do understand. We landed on Mars on the 4 percent we do understand. So the day we crack the nut of the rest of that 95 percent… Oh my gosh.


But to carve the Grand Canyon, Earth required millions of years. To excavate Meteor Crater, the universe, using a sixty-thousand-ton asteroid traveling upward of twenty miles per second, required a fraction of a second. No offense to Grand Canyon lovers, but for my money, Meteor Crater is the most amazing natural landmark in the world.


The molecules that comprise our body are traceable to the crucibles of the centers of stars.These atoms and molecules are in us because, in fact, the universe is in us. And, we are not only figuratively, but literally, stardust.


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.


Great scientific minds, from Claudius Ptolemy of the second century to Isaac Newton of the seventeenth, invested their formidable intellects in attempts to deduce the nature of the universe from the statements and philosophies contained in religious writings…. Had any of these efforts worked, science and religion today might be one and the same. But they are not.


I [do not know] when the end of science will come. … What I do know is that our species is dumber than we normally admit to ourselves. This limit of our mental faculties, and not necessarily of science itself, ensures to me that we have only just begun to figure out the universe.


I have found that when calculating what no one has calculated before, like my observing sessions on the mountain, my mental acuity peaks. Ironically, these are the times that I would flunk the reality check normally reserved for mental patients and dazed boxers: What is your name? What day is it? Who is the president of the United States?… I do not know, and I do not care. I am at peace with my equations as I connect to the cosmic engines that drive our universe.


If cosmological theory were dominated by women, who are no strangers to cycles, how can we know for sure that we wouldn’t then be told that the oscillating universe is the more aesthetically fulfilling alternative?


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.


If you are that person, you are more likely to believe that God cured you, this invisible force, creator of the universe, cured you, than that you had three idiotic doctors diagnose you. … I taught physics to pre-med students who became doctors. Not all of them are smart, I assure you.


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.


After all, what nobler thought can one cherish than that the universe lives within us all?


Some molecules – ammonia, carbon dioxide, water – show up everywhere in the universe, whether life is present or not. But others pop up especially in the presence of life itself. Among the biomarkers in Earth’s atmosphere are ozone-destroying chlorofluorocarbons from aerosol sprays, vapor from mineral solvents, escaped coolants from refrigerators and air conditioners, and smog from the burning of fossil fuels. No other way to read that list: sure signs of the absence of intelligence.


We are part of this universe; we are in this universe, but perhaps more important than both of those facts, is that the universe is in us.


Unlike what you may be told in other sectors of life, when observing the universe, size does matter, which often leads to polite ‘telescope envy’ at gatherings of amateur astronomers.


I lose sleep at night wondering whether we are intelligent enough to figure out the universe. I don’t know.


Part of me thinks that I’ve been called by the universe, to get all sort of spiritual about it. Like, I’ve had no actual say in the matter. The universe found me.


It’d be a shame to talk about the universe and not show some images of it, because we have some of the more stunning representations of our field relative to any of the sciences. But I don’t use the imagery as a substitute for the insights and wisdom I can convey so that when you leave you say to yourself, “Wow, I’m a little more deeply connected to the universe, and I want to learn more.”


I can tell you about the universe, but she feels it; and when you feel the universe, it has a whole other meaning to you. Otherwise, you just put a Wiki page on camera. You can learn something, but it won’t mean anything to you later on.


The universe’s destiny has very little to do with the near-term destiny of Earth.


I try to keep this in mind when tied in to a rope 75 feet up in a tree… The history of ideas about our place in the universe has been a long series of let-downs for those who like to believe we are special.


Many people feel small because they’re small and the universe is big, but I feel big.


I love the smell of the universe in the morning.


We already know the limits of Einstein’s theories. From the centers of black holes at the very beginning of the universe – we call these singularities – Einstein’s equations fail. In fact, people have joked that’s where God is dividing by zero.
