Cosmologists

"The problem, often not discovered until late in life, is that when you look for things like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation. For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And along the way, lessen the suffering of others. You'd be surprised how far that gets you."

"There are street artists. Street musicians. Street actors. But there are no street physicists. A little known secret is that a physicist is one of the most employable people in the marketplace - a physicist is a trained problem solver. How many times have you heard a person in a workplace say, "I wasn't trained for this!" That's an impossible reaction from a physicist, who would say, instead, "Cool. A problem I've never seen before. Let's see how I can figure out how to solve it!" Oh, and, have fun along the way."

"Life is too short for me to worry about something I have no control over that I don’t even know will happen. People ask ‘if Earth is going to be swallowed by a black hole or if there is some disturbance in the spacetime continuum should we worry about it?’. My answer is ‘no’ because you won’t know about it until it crosses your... your place in space-time. Your beats come to you when nature decides it’s the right time... be it the speed of sound, the speed of light, the speed of electrical impulses we will forever be victims of the time delay between information around us and our capacity to receive it."

"What keeps me awake at night: wondering whether human species is just too stupid to figure out the Universe. I just wonder. I lose sleep over that. Because we define ourselves as intelligent— because we made up the test to say that. And we sit alone at the top of the intelligence chart because we invented the exam, and all the other species of life on Earth are not. So who's to say that the first species (us) to be intelligent (us) has just enough intelligence to actually decode everything that's decodable in the Cosmos? [...] Think of the next closest thing to us, the bonobo chimp— 98½% identical DNA, yet you cannot teach them trigonometry, they have no concept of it. So if that's only 1½% difference in our DNA— and so imagine 1½% beyond us, rather than below us, in intelligence. [...] Their toddlers would be talking about things that would completely confound us."

"What is NASA's mission? Is it to beat the russians? Is it to inspire?"

"If you want to assert a truth, first make sure it's not just an opinion that you desperately want to be true."

"All I can say is, the universe is in a good shape, it's earth that has all the problems."

"As important as Steve Jobs was, no doubt about it — [and] you have to add him to Bill Gates, because they birthed the personal computing revolution kind of together — here's the difference: Elon Musk is trying to invent a future, not by providing the next app."

"The universe is under no obligation to make sense to you."

"Ignorance is the natural state of mind for a research scientist. People who believe they are ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the universe. What we do know, and what we can assert without further hesitation, is that the universe had a beginning. The universe continues to evolve. And yes, every one of our body’s atoms is traceable to the big bang and to the thermonuclear furnaces within high-mass stars that exploded more than five billion years ago. We are stardust brought to life, then empowered by the universe to figure itself out—and we have only just begun."

"This universality of physical laws drives scientific discovery like nothing else."

"To the scientist, the universality of physical laws makes the cosmos a marvelously simple place. By comparison, human nature—the psychologist’s domain—is infinitely more daunting. In America, local school boards vote on subjects to be taught in the classroom. In some cases, votes are cast according to the whims of cultural, political, or religious tides. Around the world, varying belief systems lead to political differences that are not always resolved peacefully. The power and beauty of physical laws is that they apply everywhere, whether or not you choose to believe in them. In other words, after the laws of physics, everything else is opinion."

"Cosmologists have plenty of ego. How could you not when your job is to deduce what brought the universe into existence?"

"In our own solar system, for example, everything that is not the Sun adds up to less than one fifth of one percent of the Sun’s mass."

"Other unrelenting skeptics might declare that “seeing is believing”—an approach to life that works well in many endeavors, including mechanical engineering, fishing, and perhaps dating. It’s also good, apparently, for residents of Missouri. But it doesn’t make for good science. Science is not just about seeing, it’s about measuring, preferably with something that’s not your own eyes, which are inextricably conjoined with the baggage of your brain. That baggage is more often than not a satchel of preconceived ideas, post-conceived notions, and outright bias."

"Personally, I am quite comfortable with chemicals, anywhere in the universe. My favorite stars, as well as my best friends, are all made of them."

"Of all the sciences cultivated by mankind, Astronomy is acknowledged to be, and undoubtedly is, the most sublime, the most interesting, and the most useful. For, by knowledge derived from this science, not only the bulk of the Earth is discovered . . . ; but our very faculties are enlarged with the grandeur of the ideas it conveys, our minds exalted above [their] low contracted prejudices."

"When I pore over the data that establish the mysterious presence of dark matter and dark energy throughout the universe, sometimes I forget that every day—every twenty-four-hour rotation of Earth—people kill and get killed in the name of someone else’s conception of God, and that some people who do not kill in the name of God, kill in the name of needs or wants of political dogma."

"Within a month of opening day, I received a letter from an Ivy League professor of psychology whose expertise was in things that make people feel insignificant…He wanted to administer a before-and-after questionnaire to visitors, assessing the depth of their depression after viewing the show. Passport to the Universe, he wrote, elicited the most dramatic feelings of smallness and insignificance he had ever experienced. How could that be? Every time I see the space show (and others we’ve produced), I feel alive and spirited and connected. I also feel large, knowing that the goings-on within the three-pound human brain are what enabled us to figure out our place in the universe. Allow me to suggest that it’s the professor, not I, who has misread nature. His ego was unjustifiably big to begin with, inflated by delusions of significance and fed by cultural assumptions that human beings are more important than everything else in the universe. In all fairness to the fellow, powerful forces in society leave most of us susceptible. As was I, until the day I learned in biology class that more bacteria live and work in one centimeter of my colon, than the number of people who have ever existed in the world. That kind of information makes you think twice about who–or what–is actually in charge. From that day on, I began to think of people not as the masters of space and time but as participants in a great cosmic chain of being, with a direct genetic link across species both living and extinct, extending back nearly four billion years to the earliest single-celled organisms on Earth."

"If a huge genetic gap separated us from our closest relative in the animal kingdom, we could justifiably celebrate our brilliance. We might be entitled to walk around thinking we’re distant and distinct from our fellow creatures. But no such gap exists. Instead, we are one with the rest of nature, fitting neither above nor below, but within."

"The cosmic perspective flows from fundamental knowledge. But it’s more than about what you know. It’s also about having the wisdom and insight to apply that knowledge to assessing our place in the universe. And its attributes are clear: The cosmic perspective comes from the frontiers of science, yet it is not solely the provenance of the scientist. It belongs to everyone. The cosmic perspective is humble. The cosmic perspective is spiritual—even redemptive—but not religious. The cosmic perspective enables us to grasp, in the same thought, the large and the small. The cosmic perspective opens our minds to extraordinary ideas but does not leave them so open that our brains spill out, making us susceptible to believing anything we’re told. The cosmic perspective opens our eyes to the universe, not as a benevolent cradle designed to nurture life but as a cold, lonely, hazardous place, forcing us to reassess the value of all humans to one another. The cosmic perspective shows Earth to be a mote. But it’s a precious mote and, for the moment, it’s the only home we have. The cosmic perspective finds beauty in the images of planets, moons, stars, and nebulae, but also celebrates the laws of physics that shape them. The cosmic perspective enables us to see beyond our circumstances, allowing us to transcend the primal search for food, shelter, and a mate. The cosmic perspective reminds us that in space, where there is no air, a flag will not wave, an indication that perhaps flag-waving and space exploration do not mix. The cosmic perspective not only embraces our genetic kinship with all life on Earth but also values our chemical kinship with any yet-to-be discovered life in the universe, as well as our atomic kinship with the universe itself."

"At least once a week, if not once a day, we might each ponder what cosmic truths lie undiscovered before us, perhaps awaiting the arrival of a clever thinker, an ingenious experiment, or an innovative space mission to reveal them. We might further ponder how those discoveries may one day transform life on Earth. Absent such curiosity, we are no different from the provincial farmer who expresses no need to venture beyond the county line, because his forty acres meet all his needs. Yet if all our predecessors had felt that way, the farmer would instead be a cave dweller, chasing down his dinner with a stick and a rock."

"in Space where there ain't no gravity, helicopter dick really do be a way to travel."

"... the anatomy of a sound bite is—it's gotta be interesting. And it's gotta be tasty. It should also be a little bit fun to hear ... so that you smile. And it's gotta have enough of all that to want to tell someone else that you just learned something. ... I have a master class on thinking like a scientist and how to communicate what you know in your expertise to others."

"Science is a cooperative enterprise spanning the generations. It's the passing of a torch from teacher to student to teacher; a community of minds reaching back to antiquity and forward to the stars. (From the first Cosmos: ASO episode, Standing Up in the Milky Way.)"

"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. (From the second Cosmos: ASO episode, Some of the Things That Molecules Do.)"

"Halley shattered their monopoly, beating them at their own game. A game that no scientist had ever played before: Prophecy. -S01E03"

"Ibn al-Haytham was the first person ever to set down the rules of science. -S01E05"

"In this moment, I am euphoric. Not because of any phony god’s blessing. But because, I am enlightened by my intelligence"

"he does have that same passion to connect that is critical if you want to be a science communicator."

"Absence of evidence is not evidence of absence."

"This is exactly the kind of thing Templeton is ceaselessly angling for – recognition among real scientists – and they use their money shamelessly to satisfy their doomed craving for scientific respectability. They tried it on with the Royal Society of London, and they seem to have found a compliant Quisling in the current President, Martin Rees, who, though not religious himself, is a fervent 'believer in belief'."

"... I'd want to emphasize that most progress in cosmology and astrophysics has been due to advanced instruments and technology — less than 5 per cent to armchair theory. And I'd expect that balance to continue."

"When I discover I'm wrong, I change my mind. What do you do?"

"No one can say which approach is the right one — so no one can say how close we are to a solution."

"We’re all depressingly ‘lay’ outside our specialisms — my own knowledge, of recent biological advances, such as it is, comes largely from ‘popular’ books and journalism."

"Once the threshold is crossed when there is a self-sustaining level of life in space, then life's long-range future will be secure irrespective of any of the risks on Earth (with the single exception of the catastrophic destruction of space itself). Will this happen before our technical civilisation disintegrates, leaving this as a might-have-been? Will the self-sustaining space communities be established before a catastrophe sets back the prospect of any such enterprise, perhaps foreclosing it for ever? We live at what could be a defining moment for the cosmos, not just for our Earth."

"To eliminate the discrepancy between men's plans and the results achieved, a new approach is necessary. Morphological thinking suggests that this new approach cannot be realized through increased teaching of specialized knowledge. This morphological analysis suggests that the essential fact has been overlooked that every human is potentially a genius. Education and dissemination of knowledge must assume a form which allows each student to absorb whatever develops his own genius, lest he become frustrated. The same outlook applies to the genius of the peoples as a whole."

"But every day I go to work I'm making a bet that the universe is simple, symmetric, and aesthetically pleasing—a universe that we humans, with our limited perspective, will someday understand."

"... the Big Bang theory is the accepted theory of cosmology. You never prove anything completely, but it’s the accepted theory of cosmology. And we continue on, in my group, we continue on with balloon observations, and then there’s the and now we’re getting the ready with the , who is sponsoring that. So there’s a whole sequence. What it was, was that was the opening shot and saying OK, there’s some gold to be discovered in the hills, go looking for it."

"Zwicky became the darling of reporters everywhere. ... Though the idea of exploding stars may have been floating around, it was Zwicky who made the concepts, and the name supernova, as familiar as relativity. He always had a way with the tart phrase, as well as the boldness necessary to force it into public use, even on the rare occasion, when these attempts failed. His term for black holes—"Objects Hades"—was a much more colorful term that manages to convey both the uniqueness of the objects and the hellish conditions that prevail inside them. Despite his repeated usage, however, that name never caught on. Popular magazines noted his birthday along with those of movie stars. He even made into the funny papers."

"A cluster of galaxies gave the first hints of dark matter (in the modern sense). In 1933, F. Zwicky inferred from measurements of the velocity dispersion in the Coma cluster, a mass-to-light ratio of around 400 solar masses per solar luminoisity, thus exceeding the ratio in the solar neighborhood by two orders of magnitude."

"I myself can think of a dozen ways to annihilate all living persons within one hour."

"It is known that very distant nebulae, probably galactic systems like our own, show remarkably high receding velocities whose magnitude increases with the distance. This curious phenomenon promises to provide some important clues for the future development of our cosmological views. It maybe of advantage, therefore, to point out some of the principal facts which any cosmological theory will have to account for. Then a brief discussion will be given of different theoretical suggestions related to the above effect. Finally, a new effect of masses upon light will be suggested which is a sort of gravitational analogue of the Compton effect."

"Hydrogen is a light, odorless gas, which, given enough time, turns into people."

"Why are the heavens not filled with light? Why is the universe plunged into darkness?"

"Cosmology is a science which has only a few observable facts to work with."

"If the apparent magnitudes of the nebulae are corrected merely for the effect of the red-shift in diminishing the energy of their observed light, we have seen that Hubble claims that the system is uniformly spread out in space. If, however, the nebulae are receding, an additional dimming factor arises, and the corresponding correction for distance when incorporated in the calculation destroys the homogeneity. Instead, the number of nebulae per unit volume of space now appears to increase as we recede towards the confines of the visible universe. Rightly or wrongly, Hubble maintains that such a picture would imply that we were in a privileged position in the universe, being in the region lease densely populated with nebulae. On these, and other grounds, he is inclined, therefore, to reject the Doppler-interpretation of the red-shifts and to regard the nebulae as stationary."

"I chucked the law for astronomy, and I knew that even if I were second-rate or third-rate, it was astronomy that mattered."

"She deserved the Nobel Prize for her work."
