“ For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring. ”

“ Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun. Orbiting this at a distance of roughly ninety-two million miles is an utterly insignificant little blue green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea. ”
“ How is it that hardly any major religion has looked at science and concluded, This is better than we thought! The Universe is much bigger than our prophets said, grander, more subtle, more elegant? Instead they say, No, no, no! My god is a little god, and I want him to stay that way. A religion, old or new, that stressed the magnificence of the Universe as revealed by modern science might be able to draw forth reserves of reverence and awe hardly tapped by the conventional faiths. ”

“ The role played by time at the beginning of the universe is, I believe, the final key to removing the need for a Grand Designer, and revealing how the universe created itself. … Time itself must come to a stop. You can’t get to a time before the big bang, because there was no time before the big bang. We have finally found something that does not have a cause because there was no time for a cause to exist in. For me this means there is no possibility of a creator because there is no time for a creator to have existed. Since time itself began at the moment of the Big Bang, it was an event that could not have been caused or created by anyone or anything. … So when people ask me if a god created the universe, I tell them the question itself makes no sense. Time didn’t exist before the Big Bang, so there is no time for God to make the universe in. It’s like asking for directions to the edge of the Earth. The Earth is a sphere. It does not have an edge, so looking for it is a futile exercise. ”
“ My view is that if your philosophy is not unsettled daily then you are blind to all the universe has to offer. ”
“ And when the universe has finished exploding all the stars will slow down, like a ball that has been thrown into the air, and they will come to a halt and they will all begin to fall towards the centre of the universe again. And then there will be nothing to stop us seeing all the stars in the world because they will all be moving towards us, gradually faster and faster, and we will know that the world is going to end soon because when we look up into the sky at night there will be no darkness, just the blazing light of billions and billions of stars, all falling. ”

“ The Hindu religion is the only one of the world’s great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths.
It is the only religion in which the time scales correspond to those of modern scientific cosmology. Its cycles run from our ordinary day and night to a day and night of Brahma, 8.64 billion years long. Longer than the age of the Earth or the Sun and about half the time since the Big Bang. ”
“ And when you look at the sky you know you are looking at stars which are hundreds and thousands of light-years away from you. And some of the stars don’t even exist anymore because their light has taken so long to get to us that they are already dead, or they have exploded and collapsed into red dwarfs. And that makes you seem very small, and if you have difficult things in you life it is nice to think that they are what is called negligible, which means they are so small you don’t have to take them into account when you are calculating something. ”

“ A blade of grass is a commonplace on Earth; it would be a miracle on Mars. Our descendants on Mars will know the value of a patch of green. And if a blade of grass is priceless, what is the value of a human being? ”

“ Sometimes I think we're alone in the universe, and sometimes I think we're not. In either case, the idea is quite staggering. ”
“ The bright sun was extinguish'd, and the stars
Did wander darkling in the eternal space. ”
“ We live on a hunk of rock and metal that circles a humdrum star that is one of 400 billion other stars that make up the Milky Way Galaxy which is one of billions of other galaxies which make up a universe which may be one of a very large number, perhaps an infinite number, of other universes. That is a perspective on human life and our culture that is well worth pondering. ”
“ The full cosmos consists of the physical stuff
and
consciousness. Take away consciousness and it's only dust; add consciousness and you get things, ideas, and time. ”
“ Science is opposed to theological dogmas because science is founded on fact. To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine. Nothing enters our minds or determines our actions which is not directly or indirectly a response to stimuli beating upon our sense organs from without. Owing to the similarity of our construction and the sameness of our environment, we respond in like manner to similar stimuli, and from the concordance of our reactions, understanding is born. In the course of ages, mechanisms of infinite complexity are developed, but what we call 'soul' or 'spirit,' is nothing more than the sum of the functionings of the body. When this functioning ceases, the 'soul' or the 'spirit' ceases likewise.
I expressed these ideas long before the behaviorists, led by Pavlov in Russia and by Watson in the United States, proclaimed their new psychology. This apparently mechanistic conception is not antagonistic to an ethical conception of life. ”
“ The total amount of energy from outside the solar system ever received by all the radio telescopes on the planet Earth is less than the energy of a single snowflake striking the ground. ”
“ How can we satisfy ourselves without going on in infinitum? And, after all, what satisfaction is there in that infinite progression? Let us remember the story of the Indian philosopher and his elephant. It was never more applicable than to the present subject. If the material world rests upon a similar ideal world, this ideal world must rest upon some other; and so on, without end. It were better, therefore, never to look beyond the present material world. ”
“ It took less than an hour to make the atoms, a few hundred million years to make the stars and planets, but five billion years to make man! ”
“ Science cuts two ways, of course; its products can be used for both good and evil. But there's no turning back from science. The early warnings about technological dangers also come from science. ”

“ For Man to tell how human life began is hard; for who himself beginning knew? ”
“ In the beginning there were only probabilities. The universe could only come into existence if someone observed it. It does not matter that the observers turned up several billion years later. The universe exists because we are aware of it. ”
“ The Universe was a damned silly place at best . . . but the least likely explanation for its existence was the no-explanation of random chance, the conceit that some abstract somethings "just happened" to be some atoms that "just happened" to get together in configurations which "just happened" to look like consistent laws and then some of these configurations "just happened" to possess self-awareness and that two such "just happened" to be the Man from Mars and the other a bald-headed old coot with Jubal himself inside.
No, Jubal would not buy the "just happened" theory, popular as it was with men who called themselves scientists. Random chance was not a sufficient explanation of the Universe--in fact, random chance was not sufficient to explain random chance; the pot could not hold itself. ”
“ Like the microscopic strands of DNA that predetermine the identity of a macroscopic species and the unique propertires of its members, the modern look and feel of the cosmos was writ in the fabric of its earliest moments, and carried relentlessly through time and space. We feel it when we look up. We feel it when we look down. We feel it when we look within. ”
“ There cannot be a language more universal and more simple, more free from errors and obscurities...more worthy to express the invariable relations of all natural things [than mathematics]. [It interprets] all phenomena by the same language, as if to attest the unity and simplicity of the plan of the universe, and to make still more evident that unchangeable order which presides over all natural causes ”
“ There's no obvious reason to assume that the very same rare properties that allow for our existence would also provide the best overall setting to make discoveries about the world around us. We don't think this is merely coincidental. It cries out for another explanation, an explanation that... points to purpose and intelligent design in the cosmos. ”
“ There is something stunningly narrow about how the Anthropic Principle is phrased. Yes, only certain laws and constants of nature are consistent with our kind of life. But essentially the same laws and constants are required to make a rock. So why not talk about a Universe designed so rocks could one day come to be, and strong and weak Lithic Principles? If stones could philosophize, I imagine Lithic Principles would be at the intellectual frontiers. ”

“ Some piously record 'In the beginning God', but I say 'In the beginning hydrogen'. ”
“ We have developed from the geocentric cosmologies of Ptolemy and his forebears, through the heliocentric cosmology of Copernicus and Galileo, to the modern picture in which the earth is a medium-sized planet orbiting around an average star in the outer suburbs of an ordinary spiral galaxy, which is itself only one of about a million million galaxies in the observable universe. ”
“ Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a distance one upon another, but this action is so slight at great distances that their trajectories are rectilineal; nevertheless, from time to time, two of them may come near enough together to be deviated from their course, like a comet that passed too close to Jupiter. In a word, in the eyes of a giant, to whom our Suns were what our atoms are to us, the Milky Way would only look like a bubble of gas. ”
“ It’s hard to build models of inflation that don't lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously. ”
“ Religious discourse was not intended to be understood literally because it was only possible to speak about a reality that transcended language in symbolic terms. The story of the lost paradise was a myth, not a factual account of a historical event. People were not expected to believe" it in the abstract; like any mythos, it depended upon the rituals associated with the cult of a particular holy place to make what it signified a reality in the lives of participants.
The same applies to the creation myth that was central to ancient religion and has now become controversial in the Western world because the Genesis story seems to clash with modern science. But until the early modern period, nobody read a cosmology as a literal account of the origins of life. In the ancient world, it was inspired by an acute sense of the contingency and frailty of existence. Why had anything come into being at all, when there could so easily have been nothing? There has never been a simple or even a possible answer to this question, but people continue to ask it, pushing their minds to the limit of what we can know. ”
“ There are only certain intervals of time when life of any sort is possible in an expanding universe and we can practise astronomy only during that habitable time interval in cosmic history. ”
“ The answer to the ancient question 'Why is there something rather than nothing?' would then be that ‘nothing’ is unstable. ”
“ There are reasons to doubt that what we call the laws of physics necessarily apply everywhere in the universe—or that they were applicable to every time in its history. ”
“ There is a massive, irreconcilable conflict between science and religion. Religion was humanity's original cosmology, biology and anthropology. It provided explanations for the origin of the world, life and humans. Science now gives us increasingly complete explanations for those big three. We know the origins of the universe, the physics of the big bang and how the basic chemical elements formed in supernovas. We know that life on this planet originated about 4 billion years ago, and we are all descendants of that original replicating molecule. Thanks to
Darwin
we know that natural selection is the only workable explanation for the design and variety of all life on this planet. Paleoanthropologists and geneticists have reconstructed much of the human tree of life. We are risen apes, not fallen angels. We are the most successful and last surviving African hominid. Every single person on this Earth, all 7 billion of us, arose 50,000 years ago from small bands of African hunter-gatherers, a total population of somewhere between 600 and 2,000 individuals. ”
“ The river is one of my favorite metaphors, the symbol of the great flow of Life Itself. The river begins at Source, and returns to Source, unerringly. This happens every single time, without exception. We are no different. ”
“ The sun symbolizes the Divine intelligence; the empty vastness of space symbolizes the Divine All-Possibility and also the Divine immutability; a bird symbolizes the soul; a tree symbolizes the grades of being; and water symbolizes knowledge and rain revelation. ”
“ The unity of scientific and spiritual knowledge is realized when each of the particular sciences is organically related to the supreme knowledge of al-tawhid. ”
“ Quantum fluctuations are, at their root, completely a-causal, in the sense that cause and effect and ordering of events in time is not a part of how these fluctuations work. Because of this, there seem not to be any correlations built into these kinds of fluctuations because 'law' as we understand the term requires some kind of cause-and-effect structure to pre-exist. Quantum fluctuations can precede physical law, but it seems that the converse is not true. So in the big bang, the establishment of 'law' came after the event itself, but of course even the concept of time and causality may not have been quite the same back then as they are now. ”
“ Individual events. Events beyond law. Events so numerous and so uncoordinated that, flaunting their freedom from formula, they yet fabricate firm form. ”
“ 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. ”
“ Can Christian preaching expect modern man to accept the mythical view of the world as true? To do so would be both senseless and impossible. It would be senseless, because there is nothing specifically Christian in the mythical view of the world as such. It is simply the cosmology of a pre-scientific age. ”
“ Know, child, that the One God—He is so vast that He cannot be moved, else the Universe falls. Nor can He answer, for the very act of opening His Mouth is Movement, indeed the greatest Act of all, for it is the Word. And this is precisely why He has made an infinity of lesser gods, creating them in His own image, so that we can do the lesser things on His behalf. We are His hands and arms and feet and mouths. We are His answers to your prayers, enacted along the great Framework of Being. ”
“ Then there is the cosmologist, who views himself as nothing but a manipulation of atoms; his mind configured out of randomness into the tool a vast, blind universe might use to perceive itself. If this is so then truly "all is vanity". What could be more pleasing to the cosmic narcissist than to gaze eternally with a billion eyes into the mirror that is himself? What fault, however, if certain eyes ultimately don’t like what they see? ”
