The term "landscape" comes from the notion of a fitness landscape in evolutionary biology. If there is no structure in the Landscape Theory of vacua, the problem of finding one with a sufficiently small cosmological constant is NP complete. Fine-tuning of constants like the cosmological constant or the Higgs boson mass are usually assumed to occur for precise physical reasons as opposed to taking their particular values at random. That is, these values should be uniquely consistent with underlying physical laws. The number of theoretically allowed configurations Landscape Theory prompted suggestions [ according to whom? The anthropic landscape thus refers to the collection of those portions of the landscape that are suitable for supporting intelligent life. In order to implement this idea in a concrete physical theory, it is necessary [ why? This has been realized in the context of eternal inflation. InSteven Weinberg proposed that the observed value of the cosmological constant was so small because it is impossible for life to occur in a universe with a much larger cosmological Landscape Theory. Weinberg attempted to predict the magnitude of the cosmological constant based on probabilistic arguments. Other attempts [ which? Such attempts are based in the general ideas of Bayesian probability ; Landscape Theory probability in a context where it is only possible to draw one sample from a distribution is problematic in Landscape Theory probability but not in Bayesian probability, which is not defined in terms of the Landscape Theory of repeated events. These probabilistic arguments are the most controversial aspect of the landscape. Tegmark et al. Vilenkin and collaborators have proposed a consistent way to define the probabilities for a given vacuum. A problem with many of the simplified approaches people [ who? Few dispute the large number of metastable vacua. David Gross suggests [ citation needed ] that the idea Landscape Theory inherently unscientific, unfalsifiable or premature. A famous debate on the anthropic landscape of Landscape Theory theory is the Landscape Theory debate on the merits of the landscape.

The knowledge held by different disciplines is continuous and Landscape Theory. Great achievements rarely happen within the span of a human life but grow Landscape Theory the achievements of others over many years and even generations. It is linked to the tools we use both in micro life biology, chemistry then in macro life astronomy, chemistry, geology. We Landscape Theory live with the state of knowledge and the tools we have in our own times. But we can only use the tools from our timeline — with enough flexibility to embrace what we do not Landscape Theory — and survive by being as efficient as possible. If we only had to efficiently apply what we know, we could just give the task to a device, programmed to achieve technical goals. If no human thought or effort or sensibility is necessary, it means no more civilization. Today a dominant movement in capitals and countries is to ask all inhabitants to express their ideas to contribute to the program —- that is direct democratic decision-making. I totally disagree with this. It assumes that it is not necessary to have experience and knowledge to make decisions. It Landscape Theory everyone can equally read and Landscape Theory through all the parameters of a problem; that everyone can do it. That is a total fiction. It actually happens when nobody wants to take responsibility for a direction. It is a way to say that expertise is not valid and Landscape Theory has an equally legitimate opinion. The Landscape Theory of this is what we see on social media and in the fragility of democracy. Liberty, Equality, Fraternity was a call to control human wildness and open Landscape Theory dialogue to bring together individuals and communities to make decisions affecting us all. Today we need to do that with Landscape Theory life as well as each other. That is the great challenge.

Danish landskabGerman landshaftDutch landschapand Old English landscipe combine two roots. Though no longer used in ordinary speech, the Dutch schappen conveys a magisterial sense of shaping, as in the biblical Creation. Environmental ethics matter to everyone, and the sort of virtue ethics approach outlined in the preceding section has implications for everyone alive. However, in terms of scale and impact, it is those who take managerial decisions about land, whether they are politicians, policy-makers, farmers, planners, landscape architects, property developers or foresters, who ought to examine their characteristic values and reflect on their actions the most closely. Those ethicists who have argued in favour of plural sources of values and who have been willing to embrace anthropocentric reasons for protecting the environment, are surely closer to the thinking of the majority of such professionals, as well as to that of the Landscape Theory public. Recognizing this however, we should never allow ourselves to slip into the sort of resourcist thinking which sees the environment with its multitude of component landscapes as a warehouse of reserves solely for the use of human beings, a Landscape Theory made powerfully by Heidegger in his later writings. This ecosystem-focused project becomes Landscape Theory political statement when analyzed in relation to the threat posed to the environment in Poland. Sincefollowing the green light granted by the Ministry of Environment and State Forests Agency, the forests of Poland have been ravaged, including even the most precious primeval woodlands. Since the very beginning of the project it has been clear that the more subtle a design intervention is, the better for the ecosystem. Also, after a long process of encouragement the decision was made to change Landscape Theory character of the project to non-productive and natural forest, which resulted into a no-wood-harvesting policy and protection of the Landscape Theory wood. Acting in parallel, human and non-human agents work to remake the surface of the earth and its ecosystems, though on different material and temporal scales and with different impacts, often working against each other. In this essay I posit that to construct this tension between the discrete and the continuous, and to make its representation visible, is both the work of design and the work of criticism in the age of global disruption. Still, it must be emphasized, landscapes continue to be an act of will, a social product that registers the conflicts, the diverse interests, the tensions and the pressures that Landscape Theory on it. As such, landscapes do not just Landscape Theory on their own, they must be simultaneously created, kept, maintained, and protected through institutions

    Vilenkin's Cosmic Vision A Review Essay of emMany Worlds in One The Search for Other Universesem, by Alex Vilenkin William Lane Craig Used by permission of Philosophia Christi 11 (2009): 231-8. SUMMARY Vilenkin's recent book is a wonderful popular introduction to contemporary cosmology. It contains provocative discussions of both the beginning of the universe and of the fine-tuning of the universe for intelligent life. Vilenkin is a prominent exponent of the multiverse hypothesis, which features in the book's title. His defense of this hypothesis depends in a crucial and interesting way on conflating time and space. His claim that his theory of the quantum creation of the universe explains the origin of the universe from nothing trades on a misunderstanding of "nothing." VILENKIN'S COSMIC VISION A REVIEW ESSAY OF EMMANY WORLDS IN ONE THE SEARCH FOR OTHER UNIVERSESEM, BY ALEX VILENKIN The task of scientific popularization is a difficult one. Too many authors think that it is to be accomplished by frequent resort to explanatorily vacuous and obfuscating metaphors which leave the reader puzzling over what exactly a particular theory asserts. One of the great merits of Alexander Vilenkin's book is that he shuns this route in favor of straightforward, simple explanations of key terms and ideas. Couple that with a writing style that is marvelously lucid, and you have one of the best popularizations of current physical cosmology available from one of its foremost practitioners. Vilenkin vigorously champions the idea that we live in a multiverse, that is to say, the causally connected universe is but one domain in a much vaster cosmos which comprises an infinite number of such domains.

  • Exploring Cosmic Strings: Observable Effects and Cosmological Constraints
    EXPLORING COSMIC STRINGS: OBSERVABLE EFFECTS AND COSMOLOGICAL CONSTRAINTS A dissertation submitted by Eray Sabancilar In partial fulfilment of the requirements for the degree of Doctor of Philosophy in Physics TUFTS UNIVERSITY May 2011 ADVISOR: Prof. Alexander Vilenkin To my parents Afife and Erdal, and to the memory of my grandmother Fadime ii Abstract Observation of cosmic (super)strings can serve as a useful hint to understand the fundamental theories of physics, such as grand unified theories (GUTs) and/or superstring theory. In this regard, I present new mechanisms to pro- duce particles from cosmic (super)strings, and discuss their cosmological and observational effects in this dissertation. The first chapter is devoted to a review of the standard cosmology, cosmic (super)strings and cosmic rays. The second chapter discusses the cosmological effects of moduli. Moduli are relatively light, weakly coupled scalar fields, predicted in supersymmetric particle theories including string theory. They can be emitted from cosmic (super)string loops in the early universe. Abundance of such moduli is con- strained by diffuse gamma ray background, dark matter, and primordial ele- ment abundances. These constraints put an upper bound on the string tension 28 as strong as Gµ . 10− for a wide range of modulus mass m. If the modulus coupling constant is stronger than gravitational strength, modulus radiation can be the dominant energy loss mechanism for the loops. Furthermore, mod- ulus lifetimes become shorter for stronger coupling. Hence, the constraints on string tension Gµ and modulus mass m are significantly relaxed for strongly coupled moduli predicted in superstring theory. Thermal production of these particles and their possible effects are also considered.

  • Module 2—Evidence for God from Contemporary Science (Irish Final)
    Module 2—Evidence for God from Contemporary Science (Irish Final) Intro There is a long and strong relationship between the natural sciences and the Catholic Church. At least 286 priests and clergy were involved in the development of all branches of the natural sciences,1 and the Catholic Church hosts an Academy of Sciences with 46 Nobel Prize Winners as well as thousands of University and high school science departments, astronomical observatories and scientific institutes throughout the world (see Module III Section V). This should not be surprising, because as we saw in the previous Module most of the greatest scientific minds throughout history were believers (theists), and today, 51% of scientists are declared believers, as well as 88% of physicians. This gives rise to the question, “if scientists and physicians are evidence-based people, why are the majority of scientists and physicians believers?” What is their evidence? Many scientists, such as Albert Einstein and Eugene Wigner intuited clues of a divine intelligence from the wholly unexpected pervasive mathematical ordering of the universe.2 Today, the evidence for an intelligent transphysical creator is stronger than ever before despite the proliferation of many hypothetical new models of physical reality which at first seem to suggest the non-necessity of a creator. These new models include a multiverse, universes in the higher dimensional space of string theory, and multidimensional bouncing universes. So, what is this evidence that points to an intelligent creator even of multiverses, string universes, and multi- dimensional bouncing universes? There are 3 principal areas of evidence, each of which will be discussed in this Module: 1.

  • Time in Cosmology
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Philsci-Archive Time in Cosmology Craig Callender∗ C. D. McCoyy 21 August 2017 Readers familiar with the workhorse of cosmology, the hot big bang model, may think that cosmology raises little of interest about time. As cosmological models are just relativistic spacetimes, time is under- stood just as it is in relativity theory, and all cosmology adds is a few bells and whistles such as inflation and the big bang and no more. The aim of this chapter is to show that this opinion is not completely right...and may well be dead wrong. In our survey, we show how the hot big bang model invites deep questions about the nature of time, how inflationary cosmology has led to interesting new perspectives on time, and how cosmological speculation continues to entertain dramatically different models of time altogether. Together these issues indicate that the philosopher interested in the nature of time would do well to know a little about modern cosmology. Different claims about time have long been at the heart of cosmology. Ancient creation myths disagree over whether time is finite or infinite, linear or circular. This speculation led to Kant complaining in his famous antinomies that metaphysical reasoning about the nature of time leads to a “euthanasia of reason”. But neither Kant’s worry nor cosmology becoming a modern science succeeded in ending the speculation. Einstein’s first model of the universe portrays a temporally infinite universe, where space is edgeless and its material contents unchanging.

  • Creation Ex Nihilo: Theology and Science William Lane Craig
    Creation ex nihilo: Theology and Science William Lane Craig SUMMARY The biblical doctrine of temporal creation ex nihilo has received strong scientific confirmation from post-relativistic physics. Two lines of evidence point to an absolute beginning of the universe: the expansion of the universe and the thermodynamics of the universe. In each case attempts to maintain a past-eternal universe have become increasingly difficult to defend. Given the beginning of the universe, the question arises as to how the universe could have come into being. Attempts by some physicists to maintain that physics can explain the origin of the universe from nothing either trade on an equivocal use of the term “nothing” or else are guilty of philosophical faux pas. Supernatural creation ex nihilo is the better explanation. CREATION EX NIHILO: THEOLOGY AND SCIENCE Introduction “In the beginning God created the heavens and the earth” (Gen. 1.1). With majestic simplicity the author of the opening chapter of Genesis thus differentiated his viewpoint, not only from the ancient creation myths of Israel’s neighbors, but also effectively from pantheism, such as is found in religions like Vedanta Hinduism and Taoism, from panentheism, whether of classical neo- Platonist vintage or twentieth-century process theology, and from polytheism, ranging from ancient paganism to contemporary Mormonism. The biblical writers give us to understand that the universe had a temporal origin and thus imply creatio ex nihilo in the temporal sense that God brought the universe into being without a material cause at some point in the finite past. [1] Moreover, the Church Fathers, though heavily influenced by Greek thought, dug in their heels concerning the doctrine of creation, sturdily insisting on the temporal creation of the universe ex nihilo in opposition to the prevailing Hellenistic doctrine of the eternity of matter.

  • A Scenario for a Natural Origin of Our Universe Using a Mathematical Model Based on Established Physics and Cosmology
    A Scenario for a Natural Origin of Our Universe Using a Mathematical Model Based on Established Physics and Cosmology Victor J. Stenger Abstract: A mathematical model of the natural origin of our universe is presented. The model is based only on well-established physics. No claim is made that this model uniquely represents exactly how the universe came about. But the viability of a single model serves to refute any assertions that the universe cannot have come about by natural means. Why is there something rather than nothing? This question is often the last resort of the theist who seeks to argue for the existence of God from physics and cosmology and finds all his other arguments fail. Philosopher Bede Rundle calls it "philosophy's central, and most perplexing, question." His simple (but book-length) answer, "There has to be something."1 Clearly many conceptual problems are associated with this question. How do we define "nothing"? What are its properties? If it has properties, doesn't that make it something? The theist claims that God is the answer. But, then, why is there God rather than nothing? Assuming we can define "nothing," why should nothing be a more natural state of affairs than something? In fact, we can give a plausible scientific reason based on 2 our best current knowledge of physics and cosmology that something is more natural than nothing! It is commonly believed that the universe cannot have come about naturally. Although many authors writing at both the popular and academic levels have described various scenarios for a natural origin, usually based on the vague notion of "quantum fluctuations," even they admit that their ideas are speculative and surrender to the prevailing wisdom that the origin of our universe remains unexplained.2 What is it that science does when it "explains" some phenomenon? At least in the case of the physical sciences, it builds a mathematical model to describe the empirical data associated with the phenomenon.

  • Eternal Inflation, Past and Future
    Eternal Inflation, past and future Anthony Aguirre1 Department of Physics/SCIPP UC Santa Cruz 1156 High St., Santa Cruz, CA 95064 [email protected] Cosmological inflation, if it occurred, radically alters the picture of the `big bang', which would merely point to reheating at the end of inflation. More- over, this reheating may be only local so that inflation continues elsewhere and forever, continually spawning big-bang-like regions. This chapter reviews this idea of `eternal inflation’, then focuses on what this may mean for the ul- timate beginning of the universe. In particular, I will argue that given eternal inflation, the universe may be free of a cosmological initial singularity, might be eternal (and eternally inflating) to the past, and might obey an interesting sort of cosmological time-symmetry. 1 The inflationary Genie Cosmological inflation, as discussed at length in Chapter 2, was developed as a means of explaining the very simple yet specific `initial' conditions that define the hot big-bang cosmological model. But while inflation grants the wish of providing a very large, uniform, hot, monopole-free region with ap- propriate density fluctuations, it is also, like the proverbial Genie let out of the bottle, difficult to contain. In most inflation models, the selfsame accel- erated expansion that allows inflation’s explanatory and predictive successes also completely changes the ultra-large-scale structure of the universe in which it occurs, through the process of `everlasting' or `eternal' inflation.1 In this picture, once inflation starts, it continues forever { at least some- where { continually spawning non-inflating regions large enough to be our arXiv:0712.0571v1 [hep-th] 4 Dec 2007 entire observable universe.
