“The amazing thing is that every atom in your body came from a star that exploded. And, the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: You are all stardust. You couldn’t be here if stars hadn’t exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution - weren’t created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if those stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.”
“In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection. Indeed, they will be receding faster than the speed of light, so detection will be impossible. Future civilizations will discover science and all its laws, and never know about other galaxies or the cosmic background radiation. They will inevitably come to the wrong conclusion about the universe......We live in a special time, the only time, where we can observationally verify that we live in a special time.”
“If we wish to draw philosophical conclusions about our own existence, our significance, and the significance of the universe itself, our conclusions should be based on empirical knowledge. A truly open mind means forcing our imaginations to conform to the evidence of reality, and not vice versa, whether or not we like the implications.”
“Forget Jesus, the stars died so you could be born.”
“The universe is the way it is , whether we like
it or not. The existence or nonexistence of a creator is independent
of our desires . A world without God or purpose may seem harsh
or pointless, but that alone doesn ' t require God to actually exist.”
“I like to say that while antimatter may seem strange, it is strange in the sense that Belgians are strange. They are not really strange; it is just that one rarely meets them.”
“[I]n science we have to be particularly cautious about 'why' questions. When we ask, 'Why?' we usually mean 'How?' If we can answer the latter, that generally suffices for our purposes. For example, we might ask: 'Why is the Earth 93 million miles from the Sun?' but what we really probably mean is, 'How is the Earth 93 million miles from the Sun?' That is, we are interested in what physical processes led to the Earth ending up in its present position. 'Why' implicitly suggests purpose, and when we try to understand the solar system in scientific terms, we do not generally ascribe purpose to it.”
“Of course, supernatural acts are what miracles are all about. They are, after all, precisely those things that circumvent the laws of nature. A god who can create the laws of nature can presumably also circumvent them at will. Although why they would have been circumvented so liberally thousands of years ago, before the invention of modern communication instruments that could have recorded them, and not today, is still something to wonder about.”
“Now, almost one hundred years later, it is difficult to fully appreciate how much our picture of the universe has changed in the span of a single human lifetime.
As far as the scientific community in 1917 was concerned, the universe was static and eternal, and consisted of a one single galaxy, our Milky Way, surrounded by vast, infinite, dark, and empty space.
This is, after all, what you would guess by looking up at the night sky with your eyes, or with a small telescope, and at the time there was little reason to suspect otherwise.”
“One of the most poetic facts I know about the universe is that essentially every atom in your body was once inside a star that exploded. Moreover, the atoms in your left hand probably came from a different star than did those in your right. We are all, literally, star children, and our bodies made of stardust.”
“Metaphysical speculation is independent of the physical validity of the Big Bang itself and is irrelevant to our understanding of it.”
“I should point out, nevertheless, that even though incomplete data can lead to a false picture, this is far different from the (false) picture obtained by those who choose to ignore empirical data to invent a picture of reality (young earthers, for example), or those who instead require the existence of something for which there is no observable evidence whatsoever (like divine intelligence) to reconcile their view of creation with their a priori prejudices, or worse still, those who cling to fairly tales about nature that presume the answers before questions can even be asked.”
“I don’t mind not knowing. It doesn’t scare me. —RICHARD FEYNMAN”
“The universe is the way it is, whether we like it or not. The existence or nonexistence of a creator is independent of our desires. A world without God or purpose may seem harsh or pointless, but that alone doesn’t require God to actually exist.”
“Dream or nightmare, we have to live our experience as it is, and we have to live it awake.”
“Edwin Hubble, who continues to give me great faith in humanity, because he started out as a lawyer and then became an astronomer.”
“A truly open mind means forcing our imaginations to conform to the evidence of reality, and not vice versa, whether or not we like the implications.”
“We live at a very special time . . . the only time when we can observationally verify that we live at a very special time!”
“nature is more imaginative than we are.”
“There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don’t know. But there are also unknown unknowns. There are things we don’t know we don’t know. —DONALD RUMSFELD”
“I don’t make any claims to answer any questions that science cannot answer, and I have tried very carefully within the text to define what I mean by “nothing” and “something.” If those definitions differ from those you would like to adopt, so be it. Write your own book. But don’t discount the remarkable human adventure that is modern science because it doesn’t console you.”
“In this sense, science, as physicist Steven Weinberg has emphasized, does not make it impossible to believe in God, but rather makes it possible to not believe in God. Without science, everything is a miracle. With science, there remains the possibility that nothing is. Religious belief in this case becomes less and less necessary, and also less and less relevant.”
“the universe is big and old and, as a result, rare events happen all the time. Go out some night into the woods or desert where you can see stars and hold up your hand to the sky, making a tiny circle between your thumb and forefinger about the size of a dime. Hold it up to a dark patch of the sky where there are no visible stars. In that dark patch, with a large enough telescope of the type we now have in service today, you could discern perhaps 100,000 galaxies, each containing billions of stars. Since supernovae explode once per hundred years per, with 100,000 galaxies in view, you should expect to see, on average, about three stars explode on a given night.”
“For, after all, in science one achieves the greatest impact (and often the greatest headlines) not by going along with the herd, but by bucking against it.”
“Once you assume a creator and a plan, it makes humans objects in a cruel experiment whereby we are created to be sick and commanded to be well. —CHRISTOPHER HITCHENS”
“Whenever one asks “Why?” in science, one actually means “How?”. “Why?” is not really a sensible question in science because it usually implies purpose and, as anyone who has been the parent of a small child knows, one can keep on asking “Why?” forever, no matter what the answer to the previous question. Ultimately, the only way to end the conversation seems to be to say “Because!”
“Our modern conception of the universe is so foreign to what even scientists generally believed a mere century ago that it is a tribute to the power of the scientific method and the creativity and persistence of humans who want to understand it.”
“In this sense, science, as physicist Steven Weinberg has emphasized, does not make it impossible to believe in God, but rather makes it possible to not believe in God.”
“Andromeda was discovered to be another island universe, another spiral galaxy almost identical to our own, and one of the more than 100 billion other galaxies that, we now know, exist in our observable universe.”
“You too know that all my eyes see, all I touch with myself, from any distance, is Diego. The caress of fabrics, the color of colors, the wires, the nerves, the pencils, the leaves, the dust, the cells, the war and the sun, everything experienced in the minutes of the non-clocks and the non-calendars and the empty non-glances, is him.”
“there’s always light in the darkness.”
“Oh, honey, if you look close enough, everything is in those eyes. That’s why they’re so dark. They are full. Full of every secret, every promise, and every temptation that can make a good girl do really bad things and enjoy every second of it.”
“I opened my eyes as wide as I could. “Why, of course, Your Majesty. What was I thinking? I will go and do this right away, just please don’t look at me.” “Kate, get in the car.” “Maybe you should growl dramatically. I don’t think I’m intimidated enough.”
“No matter where we are today or what mistakes we've made in the past, He has given us everything we need to glorify Him right now.”
BookQuoters is a community of passionate readers who enjoy sharing the most meaningful, memorable and interesting quotes from great books. As the world communicates more and more via texts, memes and sound bytes, short but profound quotes from books have become more relevant and important. For some of us a quote becomes a mantra, a goal or a philosophy by which we live. For all of us, quotes are a great way to remember a book and to carry with us the author’s best ideas.
We thoughtfully gather quotes from our favorite books, both classic and current, and choose the ones that are most thought-provoking. Each quote represents a book that is interesting, well written and has potential to enhance the reader’s life. We also accept submissions from our visitors and will select the quotes we feel are most appealing to the BookQuoters community.
Founded in 2023, BookQuoters has quickly become a large and vibrant community of people who share an affinity for books. Books are seen by some as a throwback to a previous world; conversely, gleaning the main ideas of a book via a quote or a quick summary is typical of the Information Age but is a habit disdained by some diehard readers. We feel that we have the best of both worlds at BookQuoters; we read books cover-to-cover but offer you some of the highlights. We hope you’ll join us.
