A Universe from Nothing Quotes

“At the heart of quantum mechanics is a rule that sometimes governs politicians or CEOs—as long as no one is watching, anything goes. Systems”
― Lawrence M. Krauss, A Universe from Nothing

“Forget Jesus.
The stars died so you could be here today.”

“When it comes to understanding how our universe evolves, religion and theology have been at best irrelevant.”
― Lawrence M. Krauss, A Universe from Nothing

“Some theorists have estimated that there are perhaps 10500 different possible consistent four-dimensional universes that could result from a single ten-dimensional string theory.”
― Lawrence M. Krauss, A Universe from Nothing

“In a flat universe, and only in a flat universe, the total average Newtonian gravitational energy of each object moving with the expansion is precisely zero! This is what makes a flat universe so special. In such a universe the positive energy of motion is exactly canceled by the negative energy of gravitational attraction.”
― Lawrence M. Krauss, A Universe from Nothing

“the remaining 70 percent of the total energy in the universe resided not in any form of matter, but rather in empty space itself.”
― Lawrence M. Krauss, A Universe from Nothing

“As I have also argued, one person’s dream is another person’s nightmare. A universe without purpose or guidance may seem, for some, to make life itself meaningless. For others, including me, such a universe is invigorating. It makes the fact of our existence even more amazing, and it motivates us to draw meaning from our own actions and to make the most of our brief existence in the sun, simply because we are here, blessed with consciousness and with the opportunity to do so. Bronowski’s point, however, is that it doesn’t really matter either way, and what we would like for the universe is irrelevant. Whatever happened, happened, and it happened on a cosmic scale. And whatever is about to happen on that scale will happen independent of our likes and dislikes. We cannot affect the former, and we are unlikely to affect the latter. What we can do, however, is try to understand”

“Even if the asymmetry were 1 part in a billion there would be enough matter left over to account for everything we see in the universe today. In fact, an asymmetry of 1 part in a billion or so is precisely what was called for, because today there are roughly 1 billion photons in the cosmic microwave background for every proton in the universe. The CMBR photons are the remnants, in this picture, of the early matter-antimatter annihilations near the beginning of time.”

“Hubble’s law: There is a linear relationship between recessional velocity and galaxy distance. Namely, galaxies that are ever more distant are moving away from us with faster velocities!”
― Lawrence M. Krauss, A Universe from Nothing

“Maybe all of the mysteries of particle theory can be solved by invoking the same mantra: if the universe were any other way, we could not live in it.”
― Lawrence M. Krauss, A Universe From Nothing

“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.”
― Lawrence M. Krauss, A Universe from Nothing

“...nuestro universo desaparecerá tan abruptamente como, probablemente, empezó.”
― Lawrence M. Krauss, A Universe from Nothing: Why There Is Something Rather Than Nothing

“Science has been effective at furthering our understanding of nature because the scientific ethos is based on three key principles: (1) follow the evidence wherever it leads; (2) if one has a theory, one needs to be willing to try to prove it wrong as much as one tries to prove that it is right; (3) the ultimate arbiter of truth is experiment, not the comfort one derives from one’s a priori beliefs, nor the beauty or elegance one ascribes to one’s theoretical models. The results of experiments that I will describe here are not only timely, they are also unexpected.”
― Lawrence M. Krauss, A Universe from Nothing

“The fact that we need to refine what we mean by “common sense” in order to accommodate our understanding of nature is, to me, one of the most remarkable and liberating aspects of science. Reality liberates us from the biases and misconceptions that have arisen because our intellects evolved through our animal ancestors, whose survival was based on whether predators might lurk behind trees or in caves and not on understanding the wave function of electrons in atoms. 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. That is worth celebrating. As I describe in this book, the question and the possible answers to how something might come from nothing are even more interesting than merely the possibility of galaxies manifesting from empty space. Science provides a possible road map for the creation of space (and time) itself—and perhaps also an understanding of how the laws of physics that govern the dynamics of space and time can arise haphazardly.”

“sensible”

“Higgs”
― Lawrence M. Krauss, A Universe from Nothing

“We have discovered that all signs suggest a universe that could and plausibly did arise from a deeper nothing – involving the absence of space itself – and which one day may return to nothing via processes that may not be comprehensible but also processes that do not require any external control or direction. In this sense, science, as 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.”

“Why is there something rather than nothing? Ultimately, this question may be no more significant or profound than asking why some flowers are red and some are blue. ‘Something’ may always come from nothing. It may be required, independent of the underlying nature of reality. Or perhaps ‘something’ may not be very special or even very common in the multiverse. Either way, what is really useful is not pondering this question, but rather participating in the exciting voyage of discovery that may reveal specifically how the universe in which we lived evolved and is evolving and the processes that ultimately operationally govern our existence. That is why we have science. We may supplement this understanding with reflection and call that philosophy. But only via continuing to probe every nook and cranny of the universe that is accessible to us will we truly build a useful appreciation of our own place in the universe.”

“I cannot overstress the importance of the fact that, once gravity is included in our considerations of nature, one is no longer free to define the total energy of a system arbitrarily, nor the fact that there are both positive and negative contributions to this energy…I say this because it have been argued that the statement that the average total Newtonian gravitational energy in a flat, expanding universe is arbitrary, and that any other balue would be just as good, but that scientists ‘define’ the zero point to argue against God. So claimed Dinesh D’Souza, anyway, in his debates with Christopher Hitchens on the existence of God.”

“The source of the infinity is easy to describe.”
― Lawrence M. Krauss, A Universe from Nothing

“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.”
― Lawrence M. Krauss, A Universe from Nothing: Why There Is Something Rather Than Nothing

“The central problem with the notion of creation is that it appears to require some externality, something outside of the system itself, to preexist, in order to create the conditions necessary for the system to come into being. This is usually where the notion of God—some external agency existing separate from space,”
― Lawrence M. Krauss, A Universe from Nothing

“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.”
― Lawrence M. Krauss, A Universe from Nothing

“one’s universe would appear very different from the vast bulk of space around it, which would still be inflating. In this picture, inflation is eternal. Some regions, indeed most of space, will go on inflating forever.”
― Lawrence M. Krauss, A Universe from Nothing

“the shocking revelation that empty space indeed has energy—and enough energy in fact to dominate the expansion of the universe.”
― Lawrence M. Krauss, A Universe from Nothing

“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.”
― Lawrence M. Krauss, A Universe from Nothing

“Nevertheless, the declaration of a First Cause still leaves open the question, “Who created the creator?” After all, what is the difference between arguing in favor of an eternally existing creator versus an eternally existing universe without one?”
― Lawrence M. Krauss, A Universe from Nothing

“يبدو أن أولئك الذين يطرحون حجة أن (لا شيء) يخرج من (لا شيء) راضون تماماً بالتصوُّر الرومانسي بأن الله يمكن أن يلتف حول هذا على نحو ما.”
― لورنس كراوس, كون من لا شيء

“إن الشخص المؤمن بالربوبية, الذي يجبر على البحث عن عقل كلي/ذكاء كلي ما لتأسيس نظام في الطبيعة, لن ينقاد إلى الله الشخصي في الكتب المقدسة بالمنطق ذاته.”
