The size and variation in both meaning-making and populations that characterize much contemporary text data demand research processes that support both discovery, interpretation and measurement. We assess one dominant strategy within the social sciences that takes a computer-led approach to text analysis. The approach is coined computational grounded theory. This strategy, we argue, relies on a set of unwarranted assumptions, namely, that unsupervised models return natural clusters of meaning, that the researcher can understand text with limited immersion and that indirect (...) validation is sufficient for ensuring unbiased and precise measurement. In response to this criticism, we develop a framework that is computer assisted. We argue that our reformulation of computational grounded theory better aligns with the principles within grounded theory, anthropological theory generation and ethnography. (shrink)

The big bang idea is not only a dominant idea in cosmology but also a very successfully idea out of cosmology. Although sometimes just in metaphorical sense, the big bang idea is present, since some decades, in a variety of domains such as natural sciences, humanities, social sciences, arts, and it also has a great acceptance by the general public. Furthermore, the term Big Bang has become increasingly popular and currently it is often used with very different (...) purposes, including commercial purposes, in contexts that have nothing to do with science, such as music, television, cinema, circus, house decoration, food, and other unexpected domains. Proposed by Gerald Holton, thematic analysis is a useful tool for studying cases like this, because it identifies and describes elements that cross and connect all areas of knowledge and culture in general and thus can help to understand the reception, appropriation and use of certain ideas in different but contemporary disciplinary and cultural contexts, which may be involved in intellectual fashions and in styles of thought of one particular time.

Some important and decisive observations allowed a widespread and almost unquestionable acceptance of the big bang cosmology, but we can admit and search other factors that have contributed and continue to contribute to the enormous acceptance and great popularity of this cosmological conception, not only inside but also outside of cosmology and even in numerous no scientific contexts. To find some of those factors, a case study was undertaken based on thematic analysis, an analytical tool which is based on (...) the idea that the scientific activity, in addition to a theoretical and an experimental dimensions, has a third dimension with psychological and cultural elements called themata that strongly influence the construction of scientific theories and also their acceptance or rejection. This case study focused on the most important founding texts of big bang cosmology, namely articles and books of Alexandre Friedmann, Georges Lemaître, and George Gamow, covering three decades of important developments, and the founding texts of its great rival, the steady-state cosmology. This article presents a summary of the main results of this case study, which allowed to identify several themata with a very important role in the big bang cosmology: differentiation and unification ; unity, creation, change, evolution, constancy, simplicity, life cycle, circularity, and disorder. All these themata form a methodological and conceptual matrix—with a triple dimension: historical, transversal/cultural, and psychological—that can help explain the acceptance and popularity of the big bang cosmology within and beyond its disciplinary boundaries.

Recent computer simulations indicate that a system ofn gravitating masses breaks up, even when the total energy is negative. As a result, almost any initial phase-space distribution results in a universe that eventually expands under the Hubble law. Hence Hubble expansion implies little regarding an initial cosmic state. Especially it does not imply the singularly dense superpositioned state used in the big bang model.

By dividing the creation of matter, energy, life, and mind into three big bangs, Holmes Rolston III brings into focus a history of the universe that respects both scientific discovery and the potential presence of an underlying intelligence. Matter-energy appears, initially in simpler forms but with a remarkable capacity for generating heavier elements. The size and expansion rate of the universe, the nature of electromagnetism, gravity, and nuclear forces enable the the explosion of life on Earth. DNA discovers, stores, and (...) transfers information generating billions of species. Cognitive capacities escalate, and with neural sentience this results in human genius. A massive singularity, the human mind gives birth to language and culture, increasing the brain's complexity and promoting the spread of ideas. Ideas generate ideals, which lead life to take on spirit. The nature of matter-energy, genes, and their genesis therefore encourages humans to wonder where they are, who they are, and what they should do. (shrink)

Contemporary science presents us with the remarkable theory that the universe began to exist about fifteen billion years ago with a cataclysmic explosion called "the Big Bang." The question of whether Big Bang cosmology supports theism or atheism has long been a matter of discussion among the general public and in popular science books, but has received scant attention from philosophers. This book sets out to fill this gap by means of a sustained debate between two philosophers, William (...) Lane Craig and Quentin Smith, who defend opposing positions. Craig argues that the Big Bang that began the universe was created by God, while Smith argues that the Big Bang has no cause. Alternating chapters by the two philosophers criticize and attempt to refute preceding arguments. Their arguments are based on Einstein's theory of relativity and include a discussion of the new quantum cosmology recently developed by Stephen Hawking and popularized in A Brief History of Time.

Some believe that evidence for the big bang is evidence for the existence of god. Who else, they ask, could have caused such a thing? In this paper, I evaluate the big bang argument, compare it with the traditional first-cause argument, and consider the relative plausibility of various natural explanations of the big bang.

The singularity theorems of the 1960s showed that Lemaître’s initial symmetry assumptions were not essential for deriving a big-bang origin for a vast multitude of relativistic universe models. Yet the actual universe accords remarkably closely with models of Lemaître’s type. This is a mystery closely related to the form taken by the 2nd law of thermodynamics and is not explained by currently conventional inflationary cosmology. Conformal cyclic cosmology provides another perspective on these issues, one consequence being the necessary initial (...) presence of a dominant scalar material that interacts only gravitationally, but which must ultimately slowly decay away in a novel but perhaps detectable way. According to CCC, our current universe picture provides but one aeon of an unending succession of expanding aeons each having an initial big bang which is the conformal continuation of the remote exponential expansion of its previous aeon. The observational status of CCC is briefly discussed. (shrink)

The big bang cosmological theory is relevant to Christian theism and other theist perspectives since it represents the universe as beginning to exist ex nihilo about 15 billion years ago. This paper addresses the question of whether it is reasonable to believe that God created the big bang. Some theists answer in the affirmative, but it is argued in this paper that this belief is not reasonable. In the course of this argument, there is a discussion of the (...) metaphysical necessity of natural laws, of whether the law of causality is true a priori, and of other pertinent issues. (shrink)

Each scientific study emerges in its own particular time and marks a new step in the development of human thought.1 Big History materialized to satisfy the human need for a unified vision of our existence. It came together in the waning decades of the twentieth century, in part, as a reaction to the specialization of scholarship and education that had taken hold around the world. While this specialization had great results, it created barriers that stood in contrast to a growing (...) unity among our global communities. These barriers were increasingly awkward to bridge, and, thus, Big History emerged as a successful new framework. (shrink)

We show that the big bang is a coordinate singularity for a large class of \ inflationary FLRW spacetimes which we have dubbed ‘Milne-like.’ By introducing a new set of coordinates, the big bang appears as a past boundary of the universe where the metric is no longer degenerate—a result which has already been investigated in the context of vacuum decay. We generalize their results and approach the problem from a more mathematical perspective. Similar to how investigating the (...) geometrical properties of the \ event horizon in Schwarzschild led to a better understanding of black holes, we believe that investigating the geometrical properties of the big bang coordinate singularity for Milne-like spacetimes could lead to a better understanding of cosmology. We show how the mathematics of these spacetimes may help illuminate certain issues associated with dark energy, dark matter, and the universe’s missing antimatter. (shrink)

One of the world’s largest collections of European modern art, held by Centre Georges Pompidou, was displayed for the first time in a thematically-curated exhibition, The Big Bang. This review article evaluates the merits and permutations of thematic curation, in lieu of The Big Bang’s relation to previous instances of thematic curation of significant museum collections, most notably at the Museum of Modern Art and Tate Modern. The Big Bang is also considered against the ideological underpinnings of (...) both thematic and chronological curation, and their implications for the future. (shrink)

William Lane Craig has defended a modern First Cause argument based on 1) a principle of universal causality and 2) the claim that the universe must have had a beginning. But 1) is susceptible to counter examples from quantum theory. Moreover, Craig’s defense of 2) is open to serious question. He claims that an actual infinity (of time) is impossible; he also claims that 2) is in fact supported by big bang theory. I argue that both of these claims (...) are mistaken, and that in consequence we have no particular reason to suppose that 2) is true. I conclude that the First Cause argument fails, but I suggest that a weaker inductive argument might be worth a try. (shrink)

The first two thirds or so of this book is a thorough, severe, and at times somewhat difficult, philosophical analysis and critique of atheistic naturalistic answers to “What caused the Big Bang?” Most contemporary astrophysicists accept one of the following non-theistic accounts of the origin of the Big Bang: Steady State, Plasma, Oscillationist, Big Fizz, Big Divide, Quantum Observership, Big Accident, Atheistic Anthropic, and Plenitude cosmologies. The last third or so of the book develops a highly plausible theistic (...) process cosmology which includes creation ex nihilo. This book critically explores answers to the big question, What produced our universe around fifteen billion years ago in a Big Bang? It defends and revises Process Theology and develops contemporary arguments for God's existence based on the universe's life-supporting order and contingent existence. (shrink)

Was the Big Bang with which the universe began created by God, or did it occur without cause? In this book two philosophers of opposite viewpoints debate the question.

Now imagine that this accelerated gold nucleus has a head-on collision with a second nuclear pancake, a gold nucleus accelerated to the same ultra-relativistic velocity but in the opposite direction. Momentarily, the two pancakes in this light-speed head-on collision will overlap. The masses of the nuclei have been increased by a factor of 108, and the mass of each is contained in a volume that has been reduced by a factor of 108. As a result, neglecting the fuzzing effects of (...) the Heisenberg uncertainty principle, the instantaneous density of.. (shrink)

The traditional presentation about historical time-passing consists in a linear succession of facts in which some aspects of the lifeworld evolve from others in anirreversible manner. The presentation of change is connected to the presentation of gradual or revolutionary linear changes that areirrevocable. I believe that this presentation could be considered correct for living organisms, but does not take account of some important aspects of demonstrative presentations about artefacts and technologies. For example, we can ontologically assume that “hammer-beating” evolved from (...) “stone-beating”. In this sense, the “hammer-beating-time” could be considered contemporary-time and the “stone-beating-time” could be considered past-time. However, we still beat things with stones and stone-like artefacts. The technology of the stone-beating is still been used. That means that relationship between the stone and the hammer cannot be seen as “evolutive” in the same sense that organisms “evolve” from each other. We must assume then, that the stone and the hammer must be interchangeable technologies which do not overshadow each other. This family of technologies and artefacts are contemporary to each other. Time-passing metaphors must then be substituted with metaphors of a “technological instability” that can be associated to a foundational cultural explosion. (shrink)

A two boundary quantum mechanics incorporating a big bang/big crunch universe is carefully considered. After a short motivation of the concept we address the central question how a proposed a-causal quantum universe can be consistent with what is known about macroscopia and how it might find experimental support.

We present here a cosmological myth, alternative to "the Universe Story" and "the Epic of Evolution", highlighting the roles of entropy and dissipative structures in the universe inaugurated by the Big Bang. Our myth offers answers these questions: Where are we? What are we? Why are we here? What are we to do? It also offers answers to a set of "why" questions: Why is there anything at all? and Why are there so many kinds of systems? - the (...) answers coming from cosmology and physics ; Why do systems not last once they exist? - the answer coming from a materialist interpretation of information theory; and, Why are systems just the way they are and not otherwise? - the answer coming from evolutionary biology. We take into account the four kinds of causation designated by Aristotle as efficient, final, and material formal, with the Second Law of thermodynamics in the role of final cause. Conceptual problems concerning reductionism, "teleology", and the choice/chance distinction are dealt with in the framework of specification hierarchy, and the moral implications of our story explored in the conclusion.

A Brief History of Time: From the Big Bang to Black Holes is a popular-science book on cosmology (the study of the origin and evolution of the universe) by British physicist Stephen Hawking. It was first published in 1988. Hawking wrote the book for readers who have no prior knowledge of the universe and people who are interested in learning.

The cosmic singularity provides negligible evidence for creation in the finite past, and hence theism. A physical theory might have no metric or multiple metrics, so a ‘beginning’ must involve a first moment, not just finite age. Whether one dismisses singularities or takes them seriously, physics licenses no first moment. The analogy between the Big Bang and stellar gravitational collapse indicates that a Creator is required in the first case only if a Destroyer is needed in the second. The (...) need for and progress in quantum gravity and the underdetermination of theories by data make it difficult to take singularities seriously. The singularity exemplifies the sort of gap that is likely to be closed by scientific progress, obviating special divine action. The apparent irrelevance of cardinality to practices of counting infinite sets in classical field theory and Fourier analysis is noted.

In a recent paper, John J. Park argues (1) that an abstract object can bring a universe into existence, and (2) that, according to the Big Bang Theory, the initial singularity is an abstract object that brought the universe into existence. According to Park, if (1) and (2) are true, then the kalam cosmological argument fails to show that the cause of the universe must be divine. I argue, however, that both (1) and (2) are false. In my argument (...) I analyse the abstract/concrete distinction and conclude that, by its nature, an abstract object is causally inefficacious in the sense that it cannot bring something into existence. (shrink)

There are long-standing questions about the Big Bang: What were its properties? Was there nothing before it? Was the universe always here? Many conceptual issues revolve around time. This paper gives a novel model based on McTaggart’s temporal distinction between the A-series (future-present-past) and B-series (earlier-times to later-times). These series are useful while situated in a Presentist and Fragmentalist account of quantum mechanics, one in which the consistency with the Special Relativity (in particular the relativity of simultaneity) will be (...) made explicit (section 6). This allows us to make a fruitful distinction between two pertinent questions: what happens as we go to earlier times toward the Big Bang? And: what happens as we go further into the past toward the Big Bang? (shrink)

This column is about a new alternative to standard Big Bang cosmology that reaches back in time to the era before the Big Bang in an effort to remove some of the arbitrary assumptions from the model. It's in part the work of Gabriele Veneziano, a theorist at CERN, and it is called pre-Big-Bang cosmology. We'll begin by reviewing the standard scenario of the origin of the universe.

I'm Professor of Physics at the University of Washington in Seattle . I do basic research in ultra-relativistic heavy ion physics with the STAR experiment, using the RHIC facility at Brookhaven National Laboratory, colliding gold nuclei to produce systems that look something like the first microsecond of the Big Bang. I do not work much in cosmology and astrophysics, although I've published a paper or two in those areas, but I do write a bi-monthly science column for Analog Science (...) Fiction/Fact Magazine . One of my columns was entitled BOOMERanG and the Sound of the Big Bang " and was published in the January-2001 issue of Analog. It described the then-recent Antarctic balloon flight that mapped the small-angle temperature variations of the cosmic background radiation. Following the lead of the scientists involved in the project, I described the temperature variations they observed as, in effect, a recording of the "sound of the Big Bang" when the universe was 376 thousand years old.

It is at this juncture that post-modernism in the science field lacks that remaining piece of discipline, accepting the existence of an absolute, inner fabric of creative intelligence that is responsible for the vibratory formation of all physical world phenomena. It is for this reason that science alone will not find a viable answer of how the universe was created. Thus far, the science hierarchy has supplied us with theories that are totally incompatible with the belief that the universe had (...) an origin connected to a creative force. Their contradictions come as a result of their atheistic/agnostic beliefs. It is the time in our evolution to make a changing of the guard. We need a new paradigm, a practical application that people can make sense of and find valuable in their daily lives. (shrink)

In this paper I examine Albert’s (2000) claim that the low entropy state of the early universe is sufficient to explain irreversible thermodynamic phenomena. In particular, I argue that conditionalising on the initial state of the universe does not have the explanatory power it is presumed to have. I present several arguments to the effect that Albert’s ‘past hypothesis’ alone cannot justify the belief in past non-equilibrium conditions or ground the veracity of records of the past.
