Cosmologists

"The will to procreate, as lust, engenders wealth and leads the human race to demoralisation (of which the Universal Exhibition is a striking expression), whereas the will to resuscitate, when the problem of returning life is seen as the purpose of conscious beings, moralises all the worlds of the Universe, because then all the worlds that are moved by insensate forces will be governed by the brotherly feelings of all the resurrected generations. This involves both their moralisation and their rationalisation, because then the worlds of the Universe will no longer be moved by blind insensate forces but will be governed by the feelings and reason of the resurrected generations."

"Be perfect as God your Father is perfect, God the Father of the living, not of the dead. Where should we look for models of living? In the world of the animals, of blind nature, or in a world that is superior to the human race? Should the model for our society be an organism and the blind evolution of life, or should the model for our unity-in-pluralism be the Divine Trinity, within which unity is not a yoke and independence not discord? Would not then Divine creativeness, replacing our present destruction of life, serve us as a model for its re-creation?"

"A truly moral being does not need compulsion and repeated orders to perceive what his duty is – he assigns to himself his task and prescribes what must be done for those from whom he has become separated, because separation (whether voluntary or not) cannot be irreversible. Indeed, it would be criminal to repudiate those from whom one descends and to forget about their welfare. For the learned to behave thus would be to reject their own welfare, to remain prodigal sons for ever and be permanent hirelings and servants of urban caprice. This would lead them to disregard completely the needs of rural communities, that is, real needs, because the needs of such communities, unspoilt by city influences, are limited to those essentials that ensure survival in the face of hunger and illness, which not only destroy life but also displace kinship relations and replace love by enmity and hostility."

"The learned, who have fragmented science into a multiplicity of branches, imagine that the calamities that strike and oppress us are within the competence of specialised disciplines to control, whereas in fact they constitute a single problem common to all of us, namely the lack of kinship relations between a blind force and rational beings. This blind force makes no demand on us other than to endow it with what it lacks: rational direction, or regulation. Yet no regulation is possible owing to our disunity, and our disunity persists because there is no common task to unite men. Regulation, the control of the blind force of nature, can and must become the great task common to us all."

"Internal discord reflects external disunion, that is, the separation of the learned and intellectual classes from the people. Intelligence without feeling becomes the knowledge of evil without any desire to root it out, and a knowledge of good without any wish to promote it. It is an admission of lack of kinship and not a plan to re-establish kinship bonds. The consequence of indifference is oblivion for the fathers and discord among the sons. The causes of lack of kinship extend to nature as a whole, for it is a blind force uncontrolled by reason."

"Universal Christian grief is the sorrowing over disunity (that is, over enmity and hatred and their ensuing consequences such as suffering and death), and this sorrow is repentance; it is something active that includes hope, expectation and trust. Repentance is the recognition of one's guilt over disunity and of one's duty to work for unification in universal love in order to eliminate the consequences of disunity."

"[The] transformation of the blind course of nature into one that is rational [...] is bound to appear to the learned as a disruption of order, although this order of theirs brings only disorder among men, striking them down with famine, plague, and death."

"How unnatural it is to ask, ‘Why does that which exist, exist?' and yet how completely natural it is to ask, ‘Why do the living die?"

"The minorship of the human race is nowhere more evident than in the superstitious veneration of everything natural, the acceptance of the supremacy of blind nature over intelligent beings (natural morality). It is not the savages who are in this state of childishness and minority, not young nations, but the ageing ones which do not notice their superstitions and even pride themselves on being free from superstition. This happened in ancient history, it is happening now, and this state of childishness usually begins during the era of a nation's decline, though the nation believes itself to be at the zenith of its civilisation. The present puerility of Western Europe is a form of paganism, though secularised since the era of the so-called Renaissance. Death is venerated too, as being natural."

"History as fact is mutual extermination, the extermination of people like ourselves, the pillage and plunder of nature (that is, the Earth) through its exploitation and utilisation, leading to degeneration and dying (culture). History as fact is always mutual extermination, either overt in times of barbarism or covert in times of civilisation, when cruelty is merely more refined and even more evil. This situation raises the question: must man be the exterminator of his own species and the predator of nature, or must he be its regulator, its manager, and the restorer to life of his own kin, victims of his blind unruly youth, of his past – that is, of history as fact?"

"By using the mass of Earth and transforming it into conscious force, the united human race will give to the telluric force, controlled by reason and feeling — that is, by a life-giving force — domination over the blind force of other celestial bodies, and will involve them in a single life-giving force of resuscitation."

"Apart from a slowly advancing end, we cannot be certain whether a sudden catastrophe may not befall the Earth, this tiny grain of sand in the vastness of the Universe."

"If, however, progress is the transformation of the spontaneous (procreation) into conscious work, we must regard parasites as an inherent evil. The control method used is undoubtedly immoral, since it takes advantage of the natural evil of an epidemic. Nor can the annihilation of any insect be considered moral. Only the complete transfiguration of a blind force (procreation) into a conscious act can be called moral."

"Nature is regarded as a death-bearing, self-destructive force, but not because of its blindness. Yet where can a blind force lead except to death? Humans admit nature to be a blind force even when they regard themselves as part of it and accept death as a kind of law and not as a mere accident which has permeated nature and become its organic vice. Yet death is merely the result or manifestation of our infantilism, lack of independence and self-reliance, and of our incapacity for mutual support and the restoration of life. People are still minors, half-beings, whereas the fulness of personal existence, personal perfection, is possible. However, it is possible only within general perfection. Coming of age will bring perfect health and immortality, but for the living immortality is impossible without the resurrection of the dead."

"What will nature — which, in its present, unconscious state, is a force that procreates and kills - become when it achieves consciousness, if not a force restoring what it has destroyed in its blindness ? How senseless are statements about the incommensurability of the forces of man, that is, of nature striving towards consciousness and control, and the forces of the same blind nature. And should one term 'human force' merely that of man's own hand, or include what he can achieve through nature ? And are human force and human activity to be limited to what man achieves now by using the forces of nature ? Why, the true, the natural task has not even begun..."

"Contrary to Schopenhauer's 'world as will and representation', it should be 'world as slavery and the project of liberation from enslavement', from dependence, from subordination to a blind force; for us the world has no will, and for beings endowed with feeling and capable of action and not mere contemplation, the world is not solely a representation but a project of liberation from bondage. The expression 'the world as will and representation' could be justifiably replaced by the expression 'the world as lust', for lust procreates and kills, giving birth to sons and destroying the fathers. For us the world is not a representation but a project, moreover one that does not oppose lust (the opposite of lust is asceticism) but transforms the procreating force into a re-creating one, the lethal into a vivifying. Then the world can no longer remain a representation but becomes a project of the restoration of the predecessors by the offspring, that is, a project of resuscitation. That is how it should be, but at the present time the world is as it is — lust and representation."

"Man placed himself at the mercy of fate (that is to say, the annual rotation of the Earth), he submitted to the Earth; childbirth replaced the artistry of reproducing oneself in other beings, a process comparable to the birth of the Son from the Father, or the procession of the Holy Ghost. Later, proliferation increased the struggle, which was fostered by an unbridled surge of procreation; and with the increase in birth, mortality increased too. The conditions which could have regulated this concatenation of phenomena disappeared, and gradually there came revolutions, storms, drought and earthquakes; the solar system became an uncontrolled world, a star with an eleven-year cycle or some other periodicity of various catastrophes. Such is the system we know. One way or another, to confirm us in our knowledge, the solar system must be transformed into a controlled economic entity."

"If dark matter is in the form of stellar mass compact objects, then the extremes of such variability are accessible to a monitoring campaign with the Hubble Space Telescope. With the advent of the Next Generation Space Telescope, cluster dark matter in the form of compact objects will induce a ubiquitous ‘shimmering’ of the giant arcs."

"If planetary systems are ubiquitous then a fraction of stars should possess a transiting planet when being microlensed. ... For the giant planets recently identified, the deviations in the light curve can be substantial, although the specifics of the perturbations are dependent upon the radius of the planet relative to that of the star, the location of the planet over the stellar surface and the orientation of the sweeping caustic. Given that the instantaneous probability of transiting hot-Jupiter like planets is small, less than a percent, and only a proportion of microlensing events exhibit caustic crossing events, the probability of detecting a transiting planet during a microlensing event is small, ~10-6. However, a number of factors influencing this probability, such as the number of solar type star that possess planets, are uncertain, and the prospect of detecting transiting planets in future large catalogues of microlensing light curves may be viable."

"What has led astronomers and cosmologists to come to this picture we have of this expanding universe that started in the big bang?"

"Don't pay too much attention to that Nobel Prize. They have to be capricious — they have to be. And that means that people fully deserving the award don't get it."

"I don't think there is a final theory of anything. It's theories all the way down."

"I have been working in cosmology for 55 years ... I'm the last man standing, so to speak, from those early days."

"Another somewhat confusing usage is the name "the big bang" for the standard model. It is not appropriate, because it connotes a spatially isolated event, an explosion, that marked the start of everything. ... But the name has a very evident appeal and I expect that people will continue to use it."

"A solid stores energy in the vibrations of the atoms about their equilibrium positions. In the simplest approximation, which Einstein considered, each atom vibrates with the same frequency, ν, in each of three dimensions, so a solid containing N atoms can be thought of as 3N one-dimensional simple harmonic oscillators."

"The n-point correlation functions have proved useful not only as descriptive statistics but also as dynamic variables in the Newtonian theory of the evolution of clustering. ... The functions are generalized to mass correlation functions in position and momentum, and the BBGKY hierarchy of equations for their evolution is derived. This yields a new way to analyze the evolution of mass clustering in an expanding universe."

"It is established by evidence that there exists beyond the world a void without a terminal limit (khala' la nihayata laha), and it is established as well by evidence that God Most High has power over all contingent beings (al-mumkinat ). Therefore He the Most High has the power (qadir ) to create a thousand thousand worlds (alfa alfi 'awalim) beyond this world such that each one of those worlds be bigger and more massive than this world as well as having the like of what this world has of the throne (al-arsh), the chair (al-kursiyy), the heavens (al-samawat ) and the earth (al-ard ), and the sun (al-shams) and the moon (al-qamar ). The arguments of the philosophers (dala'il al-falasifah) for establishing that the world is one are weak, flimsy arguments founded upon feeble premises."

"I regret the time I have been eating instead of being in pursuit of learning - for time is precious."

"My heart was never deprived of science, There are little of the mysteries that I did not understand. For 72 years I thought night and day, Yet I came to know that nothing is to be known.”"

"If gravity is a fundamental force, then it has to be explained by an expanded version of general relativity, a more complete, a more fundamental theory. Whether that is quantum gravity of something more radical that requires a paradigm shift like, for instance, our research in multiverse theory, nobody knows at the moment."

"You can vary Newton's constant and the fine-structure constant, which is responsible for the strength of electromagnetic interactions ... by six orders of magnitude, by thousands, and still get a universe that allows for life."

"There are 10500 or more metastable vacua, which can be thought of as local minima in a huge, multidimensional potential landscape. They differ not only in the value of their vacuum energy, but in their entire low-energy effective field theory, which is determined by local properties near the foot of a valley and thus only very indirectly by the fundamental building blocks of the landscape. Different vacua will have different matter content, coupling constants, and forces. We will not predict the standard model uniquely. We will have to predict many of the features of our universe statistically, from their relative abundance in the landscape."

"The vacua with positive cosmological constant trap the universe in eternal inflation. They decay only locally, by producing bubbles of new vacua. Thus, every vacuum in the landscape will be realized an infinite number of times in different, causally disconnected regions. Each bubble expands to become an infinite open universe embedded in the global spacetime."

"if you pile up enough of it, even shit can look beautiful."

"The logic of arguments from naturalness resembles the attempt to predict the plot of a long-running TV series. If the hero -- here, naturalness --is in a pickle, certainly he will survive, so something must happen to turn around a situation that looks bleak."

"In our search for new ideas, beauty plays many roles. It's a guide, a reward, a motivation. It's also a systematic bias."

"The Standard Model is based on a principle called "gauge symmetry". According to this principle, every particle has a direction in an internal space, much like the needle in a compass, except that the needle doesn't point anywhere you can look."

"If you want to rely on non-empirical assessment, you have to make really sure that scientists’ judgment is as objective as humanly possible. And the environment in academia presently is absolutely unsuitable for this. You just can’t be sure how much sociology affects judgment. And no physicist I know makes any effort to consciously address cognitive biases, such as wishful thinking, loss aversion, or the use of aesthetic criteria. It’s just not something that they pay attention to because it’s never been necessary before. As long as you have data for guidance, you’ll be swiftly corrected."

"To make predictions with inflation one cannot just say “there once was exponential expansion and it ended somehow.” No, to be able to calculate something, one needs a mathematical model. The current models for inflation work by introducing a new field – the “inflaton” – and give this field a potential energy. The potential energy depends on various parameters. And these parameters can then be related to observations. The scientific approach to the situation would be to choose a model, determine the parameters that best fit observations, and then revise the model as necessary – ie, as new data comes in. But that’s not what cosmologists presently do. Instead, they have produced so many variants of models that they can now “predict” pretty much anything that might be measured in the foreseeable future."

"There is a prescription that works well, MOND, but the reason it works so well is not known. You may say that MOND tells us how the real theory of gravity should look."

"Bekenstein incorporated black hole entropy into a generalized second law—that the sum of the entropy outside black holes plus the newly proposed entropy of black holes must never decrease—and carefully considered processes that might violate it. To avoid violations, he found that he had to assume limitations on how close to the black hole’s horizon one could lower matter. Those ideas eventually evolved into a proposal for a bound on the entropy-to-energy ratio of matter confined to a region of given size."

"Within the DM paradigm the Tully-Fisher law must arise from galaxy formation since it connects luminosity of baryonic matter with a dynamical property, rotation, which is seen as dominated by the DM halo. But it has not been easy to derive Tully-Fisher from any natural connection between the two components. And as R. H. Sanders has pointed out, the messiness of galaxy formation is hardly the natural backdrop for such a sharp correlation between galaxy properties. The sharpness needs a dynamical reason as opposed to an evolutionary one."

"Black holes set a limitation on the number of species of elementary particles—quarks, leptons, neutrinos—which may exist. And black holes lead to a fundamental limitation on the rate at which information can be transferred for given message energy by any communication system."

"The DM halo hypothesis is evidently an attempt to resolve the acceleration discrepancy within orthodox gravitation theory. But in coming to terms with this discrepancy, suspicion fell on Newtonian gravity already early in the game. Zwicky, who had exposed the acceleration discrepancy in clusters of galaxies ..., opined much later that the discrepancy may reflect a failure of conventional physics ..."

"We show that it is natural to introduce the concept of black-hole entropy as the measure of information about a black-hole interior which is inaccessible to an exterior observer. Considerations of simplicity and consistency, and dimensional arguments indicate that the black-hole entropy is equal to the ratio of the black-hole area to the square of the Planck length times a dimensionless constant of order unity. A different approach making use of the specific properties of Kerr black holes and of concepts from information theory leads to the same conclusion, and suggests a definite value for the constant."

"Jacob was the first physicist to hear from me about MOND. It was 1982; Jacob was still at Ben Gurion University in Beer Sheba. I went there from Rehovot with my initial MOND trilogy of preprints in my bag to tell Jacob and benefit from his advice. I had not prepared him for what was in these preprints. Jacob was immediately captured, but he also warned me — as I vividly remember — that this is going to encounter much opposition, but also that I should not heed such opposition. He was drawing on his own experience with black-hole entropy and on how his ideas had been received a decade earlier."

"In a previous paper we showed that a static (nonrotating) black hole cannot be endowed with exterior scalar-meson or massive vector-meson fields. Here we show that the same is true for massive spin-2 meson fields. We also extend the above results to the case of a rotating stationary black hole. We conclude from our results that a black hole in its final (static or stationary) state cannot interact with the exterior world via the strong interactions which are mediated by meson fields such as the π (scalar), ρ (vector), and ƒ (spin-2). A direct consequence of this is the impossibility of determining the baryon number of the black hole by means of exterior measurements alone. This results in the transcendence of the law of baryon-number conservation as originally predicted by Wheeler."

"We want a fireworks theory of evolution. The last two thousand million years are slow evolution: they are the smoke and ashes of bright but very rapid fireworks."

"There is no conflict between science and religion."
