Abstract:

Modern cosmological theories like theory of eternal chaotic inflation or cosmological model of brane universe, which represent implication of modern string theory, imply existence of ensemble of actual universes which create so-called multivers. Implication of this theories are of the great importance for philosophy of time. This paper concern topology of time in context of existence of the multiverse. We will show that topology of time in such multiverse, whose particular universes would be generated due to eternal chaotic inflation, should be non-standard and that in the case of existence of multiverse only model which include topology of brenching time should be acceptable like real description of multiverse. Moreover, we will show that, the existence of hypothetical entities like Kerr`s rotating black holes, also represent necessary and sufficient condition of branching spacetime in such multiverse.

Abstract:

There are currently a large number of Multiverse hypotheses, which are, however, non-verifiable, i.e. they can be neither confirmed nor refuted experimentally even in the distant future. In contrast, the hypothesis of the hidden Multiverse considered in the article is verifiable and therefore has a right to be called a theory. The theory uses the principle of physical reality of imaginary numbers discovered 500 years ago, including complex and hypercomplex numbers, as fundamental and proved by the author theoretically and experimentally. This principle has allowed revealing a number of serious mistakes in the special theory of relativity. An adjusted version of the special theory of relativity has been proposed and the theory of the hidden Multiverse has been developed on its basis. The Multiverse has been referred to as hidden, because parallel universes it contains are mutually invisible. The nature of their invisibility is explained in the article. It is shown that dark matter and dark energy are other universes of the hidden Multiverse apart from ours. Analysis of data from WMAP and Planck spacecrafts has shown that the hidden Multiverse has quaternion structure comprising four pairs of universes and antiverses (i.e., four pairs of matter and antimatter).

Abstract:

Recent advances in string theory and inflationary cosmology have led to a surge of interest in the possible existence of an ensemble of cosmic regions, or "universes", among the members of which key physical parameters, such as the masses of elementary particles and the coupling constants, might assume different values. The observed values in our cosmic region are then attributed to an observer selection effect (the so-called anthropic principle). The assemblage of universes has been dubbed "the multiverse". In this paper we review the multiverse concept and the criticisms that have been advanced against it on both scientific and philosophical grounds.

Abstract:

In this paper we analyze the third quantization of Horava–Lifshitz theory of gravity without detail balance. We show that the Wheeler–DeWitt equation for Horava–Lifshitz theory of gravity in minisuperspace approximation becomes the equation for time-dependent harmonic oscillator. After interpreting the scaling factor as the time, we are able to derive the third quantized wave function for multiverse. We also show in third quantized formalism it is possible that the universe can form from nothing. Then we go on to analyze the effect of introducing interactions in the Wheeler–DeWitt equation. We see how this model of interacting universes can be used to explain baryogenesis with violation of baryon number conservation in the multiverse. We also analyze how this model can possibly explain the present value of the cosmological constant. Finally we analyze the possibility of the multiverse being formed from perturbations around a false vacuum and its decay to a true vacuum.

Abstract:

The current debate about a possible change of paradigm from a single universe to a multiverse scenario could have deep implications on our view of cosmology and of science in general. These implications therefore deserve to be analyzed from a fundamental conceptual level. We briefly review the different multiverse ideas, both historically and within contemporary physics. We then discuss several positions within philosophy of science with regard to scientific progress, and apply these to the multiverse debate. Finally, we construct some key concepts for a physical multiverse scenario and discuss the challenges this scenario has to deal with in order to provide a solid, testable theory.

Abstract:

AbstractThe multiverse view in set theory, introduced and argued for in this article, is the view that there are many distinct concepts of set, each instantiated in a corresponding set-theoretic universe. The universe view, in contrast, asserts that there is an absolute background set concept, with a corresponding absolute set-theoretic universe in which every set-theoretic question has a definite answer. The multiverse position, I argue, explains our experience with the enormous range of set-theoretic possibilities, a phenomenon that challenges the universe view. In particular, I argue that the continuum hypothesis is settled on the multiverse view by our extensive knowledge about how it behaves in the multiverse, and as a result it can no longer be settled in the manner formerly hoped for.

Abstract:

We evolve our Multiverse Blueprints to characterize our local neighborhood of the String Landscape and the Multiverse of plausible string, M- and F-theory vacua. Building upon the tripodal foundations of (i) the Flipped SU(5) Grand Unified Theory (GUT), (ii) extra TeV-Scale vector-like multiplets derived out of F-theory, and (iii) the dynamics of No-Scale supergravity, together dubbed No-Scale [Formula: see text], we demonstrate the existence of a continuous family of solutions which might adeptly describe the dynamics of distinctive universes. This Multiverse landscape of [Formula: see text] solutions, which we shall refer to as the [Formula: see text]-Landscape, accommodates a subset of universes compatible with the presently known experimental uncertainties of our own universe. We show that by secondarily minimizing the minimum of the scalar Higgs potential of each solution within the [Formula: see text]-Landscape, a continuous hypervolume of distinct minimum minimorum can be engineered which comprise a regional dominion of universes, with our own universe cast as the bellwether. We conjecture that an experimental signal at the LHC of the No-Scale [Formula: see text] framework's applicability to our own universe might sensibly be extrapolated as corroborating evidence for the role of string, M- and F-theory as a master theory of the Multiverse, with No-Scale supergravity as a crucial and pervasive reinforcing structure.

Abstract:

In this paper, I show that there exists a new way to obtain scalar–tensor field theories by combining a special scalar field on the cotangent bundle with a scalar field on spacetime. These two scalar fields act as a generating function for the metric tensor. When using these two scalar fields in the Horndeski Lagrangians, we discover, while seeking Friedmann–Lemaître–Robertson–Walker-type cosmological solutions, that hidden in the Horndeski Lagrangians are nondegenerate second-order scalar Lagrangians. In accordance with Ostrogradsky’s work, these hidden scalar Lagrangians lead to multiple vacuum solutions, and thereby predict the existence of the multiverse. The multiverse is comprised of numerous different types of individual universes. For example, some begin explosively, and then coast along exponentially forever at an accelerated rate, while others begin in that manner, and then stop expanding and contract.

Full text

Abstract:

In quantum gravity or string theory, it is natural to take the topology change of the space into account. We consider the low energy effective action for such case and show that it does not have a simple form of the local action but has a multilocal form. Actually, in quantum gravity or matrix model, there are some mechanisms that the low energy effective action becomes S eff = ∑ici Si + ∑ijcijSiSj + ∑ijkcijk Si Sj Sk + ⋯, where Si is a local action of the form [Formula: see text]. We further discuss that the topology change of the space naturally leads to the multiverse in which indefinite number of macroscopic universes exist in parallel. In this case, the space–time coordinates x in the multilocal action may sit either in the same universe or in different ones. We then consider the wave function of the entire multiverse, and see how the locality and causality are recovered in such theory. We further discuss the possibility of solving the naturalness problem. In doing so, we need to introduce some assumptions to interpret the multiverse wave function. We consider two different possibilities. One is to simply assume the probabilistic interpretation for the multiverse wave function. The other is to assume infrared cutoff independence of the partition function of the universe. In both cases, we find that the big fix occurs, in which all the coupling constants in the low energy physics are determined by the dynamics of the multiverse. Actually, we find that they are fixed in such a way that the total entropy of the universe at the late stage (in the far future) is maximized. Although the argument here is similar to Coleman's original one given in the late 1980s, our results are based on Lorentzian signature theory and the dynamical mechanism is rather different.

Full text

Abstract:

Here we test the predictions of the theory of the origin of the universe from the landscape multiverse, against the 2015 Planck data, for the case of the Hilltop class of inflationary models, for p = 4 and p = 6 . By considering the quantum entanglement correction of the multiverse, we can place just a lower limit on the local ’SUSY-breaking’ scale, respectively b > 8.7 × 10 6 G e V at 95 % c.l. and b > 1.3 × 10 8 G e V at 95 % c.l. from Planck TT+lowP, so the case with multiverse correction is statistically indistinguishable from the case with an unmodified inflation. We find that the series of anomalies predicted by the quantum landscape multiverse for the allowed range of b, is consistent with Planck’s tests of the anomalies. In addition, the friction between the two cosmological probes of the Hubble parameter and with the weak lensing experiments goes away for a particular subset, the p = 6 case of Hilltop models.

Abstract:

Abstract Ever since its foundations were laid nearly a century ago, quantum theory has provoked questions about the very nature of reality. We address these questions by considering the universe—and the multiverse—fundamentally as complex patterns, or mathematical structures. Basic mathematical structures can be expressed more simply in terms of emergent parameters. Even simple mathematical structures can interact within their own structural environment, in a rudimentary form of self-awareness, which suggests a definition of reality in a mathematical structure as simply the complete structure. The absolute randomness of quantum outcomes is most satisfactorily explained by a multiverse of discrete, parallel universes. Some of these have to be identical to each other, but that introduces a dilemma, because each mathematical structure must be unique. The resolution is that the parallel universes must be embedded within a mathematical structure—the multiverse—which allows universes to be identical within themselves, but nevertheless distinct, as determined by their position in the structure. The multiverse needs more emergent parameters than our universe and so it can be considered to be a superstructure. Correspondingly, its reality can be called a super-reality. While every universe in the multiverse is part of the super-reality, the complete super-reality is forever beyond the horizon of any of its component universes.

Abstract:

Unmanned spacecraft have visited the other planets of our Solar System (and some of their moons), beaming back pictures of varied and distinctive worlds – but none propitious for life. However, prospects are far more interesting when we extend our gaze to other stars. Most stars are orbited by retinues of planets. Our home Galaxy contains a billion planets like the Earth. Do some of these have biospheres? Moreover, our Galaxy is one of billions visible with a large telescope – all the aftermath of a cosmic ‘big bang’ 13.8 billion years ago. More astonishing still, ‘our’ big bang may not have been the only one. The remarkable advances in recent decades are primarily owed to new engineering and technology. Armchair theory alone doesn’t get us far.

Then, more esoteric versions of the multiverse being the realisation of some abstract mathematics or even logic (cf. paper by M. Heller in this volume). Finally, it evaluates the big challenge of getting any signal from “other universes” using recent achievements of the quantum theory.

Full text

Abstract:

In this paper, an evolutionary multiverse argument against naturalism (EMAAN) is presented: E1. In an evolutionary multiverse, phenomena have variable evolutionary ages. E2. After some time T, the development of the empirical sciences will be evolutionarily conserved. E3. The phenomena with an evolutionary age above T are methodologically supernatural. Entities are classified according to whether they are (1) physical and spatiotemporal, (2) causally efficacious, and (3) either observed by or explanatorily necessary for the empirical sciences. While the conjunction of (1) and (2) is taken to be sufficient for existence in reality, the negation of (3) defines methodological supernaturalness. EMAAN uses a generalization of evolutionary theory, namely cosmological natural selection, to argue that phenomena evolve that fulfill conditions (1) and (2), but not (3). This shows that methodologically supernatural phenomena have a clear epistemology according to a theory that is grounded in the commitments of naturalism. Supernatural phenomena are not observed by the empirical sciences because the empirical sciences themselves are supernaturally guided and predestined to develop according to an evolutionarily conserved plan. In spite of this scientific plan, there is room for afterlives and supernaturality in the everyday experience.

Full text

Abstract:

The aim of this essay is to look at the idea of the multiverse—not so much from the standpoint of physics or cosmology, but rather from a philosophical perspective. The modern story of the multiverse began with Leibniz. Although he treated “other worlds” as mere possibilities, they played an important role in his logic. In a somewhat similar manner, the practice of cosmology presupposes a consideration of an infinite number of universes, each being represented by a solution to Einstein’s equations. This approach prepared the way to the consideration of “other universes” which actually exist, first as an auxiliary concept in discussing the so-called anthropic principle, and then as real universes, the existence of which were supposed to solve some cosmological conundrums. From the point of view of the philosophy of science, the question is: Could the explanatory power of a multiverse ideology compensate for the relaxation of empirical control over so many directly unobservable entities? It is no surprise that appealing to a possibly infinite number of “other universes” in order to explain some regularities in our world would seem “too much” for a self-disciplined philosopher. With no strict empirical control at our disposal, it is logic that must be our guide. Also, what if logic changes from one world to another in the multiverse? Such a possibility is suggested by the category theory. From this point of view, our present concepts of the multiverse are certainly “not enough”. Should this be read as a warning that the learned imagination can lead us too far into the realms of mere possibilities?

Full text

Abstract:

Abstract I suggest in this article, drawing upon Francesca Ferrando, Karen Barad and N Katherine Hayles, that Disco Elysium illustrates the human through the mode of a ‘posthuman multiverse’. Per Ferrando, humans and other beings act as nodes in a material multiverse while what we think, eat, our behaviours and relations, create part of a rhizomatic ecology that can be understood as who and what we are. This, I illustrate, overcomes a complicated tension in existing posthuman theory, particularly as it relates to game studies. Although theorists have detailed the entanglement of players and machines, and the new materialist nature of becoming, it is unclear to what extent human-machine assemblages can be said to be a singular ‘thing’. This is tackled in Disco Elysium as the seemingly mundane and often invisible actions the player takes, all play a role in constructing Harry Dubois and the world that is also endlessly producing him. Game actions, therefore, can be viewed as ‘technologies of the multiverse’, the ontological functions through which beings come to exist in a dimension. The game positions the player in a ‘relational intra-activity’ not only with the actions and outcomes of play, as discussed in previous scholarship, but also with the hypothetical outcomes of choices they have not made. When read through the lens of Ferrando’s philosophical posthuman multiverse, Disco Elysium represents a valuable resource for bridging gaps in contemporary posthuman scholarship.

Abstract:

The idea of the multiverse, likely difficult to prove in traditional scientific ways, may be bolstered by two arguments from the field of logic. This article, contextualized by the metaphorical, non-logical approaches to the multiverse and situating itself within the history of astronomy, explicates these two arguments from logic. The first argument relates to the implicit illogical vanity in the assumption that our presently-known universe is special. In other words, it may be somewhat logical to embrace the history of deanthropomorphism more fully in the light of the Big Bang and the theory of cosmic inflation. The second argument suggests resolution to the long-standing philosophical and logical mysteries associated with the anthropic principle, as well as the attendant use of Ockham’s razor as a logical tool. The problem of evidence and falsifiability is briefly implicated, as well as some consequences for apologetics.

Thus, we will first deform the second quantized commutator and obtain a deformed version of the Wheeler–DeWitt equation. Then we will further deform the third quantized theory by deforming the third quantized canonical commutation relation. This way we will obtain a deformed version of the third quantized theory for the multiverse.

Full text

Abstract:

The philosophy of William James can be useful in the interpretation of works of art, although James himself never specifically set forth an aesthetic theory. As an example, a Jamesian view of consciousness is enacted on multiple levels in Charles Ives's Piano Sonata No. 2, “Concord, Mass., 1840–60,” and the accompanying Essays before a Sonata. James's metaphor for the working of the human mind—a view widely circulated in Ives's day—as a “stream of thought,” the largely transitory movement of which James likened to a bird's flights and perchings; the value James finds in vagueness; and his treatment of the nature of truth as fundamentally mutable and provisional all find musical expression in the “Concord” Sonata. Additionally, the complex genealogy of the sonata and its connection to related works, notably the Fourth and Universe Symphonies, can be interpreted as reflecting James's cosmological vision of a pluralistic universe or “multiverse.” Reading the sonata through a Jamesian lens provides new insights into the behavior of Ives's music by relating it to turn-of-the-century thinking about the functioning of the human brain as well as early-twentieth-century American philosophy and cosmology.

Abstract:

In his book Our Mathematical Universe, Max Tegmark proposes a way of viewing “reality” as a multiverse of parallel universes governed by mathematics. In this article we take a few of Tegmark’s more accessible ideas and combine them with the study of masculinities to form “quantum masculinities.” Specifically, we use Tegmark’s presentation of the multiverse and the quantum state of superposition as a thinking tool for imagining not just multiple masculinities but infinite and contradictory masculinities. We then mobilize this newly proposed concept of quantum masculinities in two contexts. First, we put quantum masculinities in dialogue with Judith Butler’s theory of gender performativity to question to what degree gender performance requires an observer. Second, we explore how far quantum masculinities are reconcilable with The Five Stages of Masculinity. We conclude with some discussion about the categories of “I” and “we” in imagining the self, as well as how the study of masculinities might evolve.

The purpose of this paper is to analyze the conditional correlation and standard deviation of a broad set of indices with the S & P 500 conditioned on market performance. Design/methodology/approach – The authors examined volatility and correlation for a set of indices for a 19-year period based on weekly data from July 2, 1993 to June 30, 2012. These included the NASDAQ, MSCI EAFE, Russell 1000, Russell 2000, Russell 3000, Russell 1000 Growth, Russell 1000 Value, Gold, MSCI EM and Dow Jones UBS Commodity. The data for the Wilshire US REIT, Barclays Multiverse, Multiverse 1-3, Multiverse 3-5 and Multiverse 10+ became available starting July 2, 2002. For these indices the authors used weekly data from July 1, 2002 through June 30, 2012. For the iBarclays TIPS, the authors used weekly data from the time of availability, namely, for the period December 12, 2003 through June 29, 2012. Findings – The findings demonstrate that both the conditional correlations and standard deviations vary as a function of market performance. Moreover, the authors obtain a U-shape distribution of correlations conditioned on market performance for equity indices, such as NASDAQ, as well as for the Wilshire REIT. Namely, correlations tend to be high when market returns are at low or high extremes. For more typical market performance, correlations tend to be low. A modified U-shape is found for bond indices and the Dow Jones UBS Commodity Index. Interestingly, the correlation between gold and the S & P 500 is unrelated to the return on the S & P. Originality/value – While it has been observed that asset classes move together, this paper is the first to systematically analyze the nature of these asset class correlations.

Abstract:

In previous studies grouped under the common denominator “Idea Collider,” the CERN Hadron-Collider was used as a metaphor to explore the meaning of breaking down existing structured and less-structured clusters of information into the finest particles to get a better understanding of the laws and nature of the universe of knowledge (Heuvel and Smiraglia, 2010). Moreover we compared past conceptualizations and visualizations of multidimensional classifications, in particular of faceted systems, and tried to assess their potential for future information retrieval (Heuvel 2011; Heuvel and Akdag Salah, 2011). Where most classification theories focused on knowledge integration in a single universe of knowledge, we outlined the framework of an elementary theory of knowledge interaction in a multiverse of knowledge (Smiraglia, Heuvel and Dousa 2011). We believe that similar to the real universe, not only matter, but also energy and gravitational forces are of importance for understanding the multiverse of information better. For that reason we want to elaborate on the question of how one perceives and interacts with knowledge production.

Abstract:

String/M theory is formulated in 10 and 11 space-time dimensions; in order to describe our universe, we must postulate that six or seven of the spatial dimensions form a small compact manifold. In 1985, Candelas et al. showed that by taking the extra dimensions to be a Calabi–Yau manifold, one could obtain the grand unified theories which had previously been postulated as extensions of the Standard Model of particle physics. Over the years since, many more such compactifications were found. In the early 2000s, progress in nonperturbative string theory enabled computing the approximate effective potential for many compactifications, and it was found that they have metastable local minima with small cosmological constant. Thus, string/M theory appears to have many vacuum configurations which could describe our universe. By combining results on these vacua with a measure factor derived using the theory of eternal inflation, one gets a theoretical framework which realizes earlier ideas about the multiverse, including the anthropic solution to the cosmological constant problem. We review these arguments and some of the criticisms, with their implications for the prediction of low energy supersymmetry and hidden matter sectors, as well as recent work on a variation on eternal inflation theory motivated by computational complexity considerations.

Abstract:

Sustainable tourism quality control tools (QCTs) are voluntary mechanisms that translate sustainable tourism concepts into practice. While essential to sustainable tourism practice, the most recent depiction of their diversity occurred in the early 2000s and identified just four types and one variability parameter. Reviewing and synthesizing the extant literature, this study identifies 15 types of QCTs, each possessing numerous variations, and seven critical variability parameters. Together these constitute the new “QCT multiverse.” This contemporary perspective on QCT diversity facilitates engagement with sustainable tourism by indicating the more comprehensive array of practices available for destination practitioners and managers.

Abstract:

The cosmological conception of the Multiverse was formulated based on unitary gauge theories in the Physics of high energy. Theoretically expected, the quantum fluctuations of the original scalar field in a vacuum state and different variants of local symmetries breaking in the process of Early Universe expansion were the reasons for the cosmological idea of many possible worlds or Multiverse. Together with the inflationary cosmological model, these ideas successfully solved the problems of Big Bang theory with an explanation of observable quasi-Euclidean geometry in our world and isotropy and homogeneity of space on a mega-scale. New observational data, especially discovery of accelerative widening of space, so as the problem of dark matter and dark energy put for cosmology the new questions. These questions need to be philosophically comprehended. Professor Sergiy Krymsky offered an interesting understanding of the notion of "matter" in the situation of many worlds in the 80s. He considered each of the possible worlds as "matter, kept in its specificity", which existed in its own space and time with its set of elements, physical laws and constants. However, his considering the original vacuum state of scalar field as non-being is not satisfied because its heterogeneity defines further places for becoming of Galaxies. In this article, the author considers the ideas about the ontological status of the original state of the Early Universe in modern cosmological Multiverse theories and discusses the possible antinomies in these transcendental ideas and their difference from Kantian ones. Experience of solution the Kant’s antinomy in history of physics was taken into account. It was the second antinomy of discreetness / continuality. The solution was haven get in a way proposed by Kant, namely with empirical research and their theoretical explanations. Cosmological application of High Energy Physics gets it to transcendental ideas area, namely to the problem of our world becoming one of the possible worlds, just as a particular variant of first Kant's antinomy. However, formulation of antinomy connected with consideration of the ontological status of original state for becoming of our world has other categorical expressions than Kantian one. The front position belongs here to categories of possibility and actuality, which Kant did not include in the area of transcendental ideas, thinking that the contingency, connecting with possibility, must be changed by inevitable necessity in cognitive progress. On the contrary, contingency has the main place in modern cosmological scenarios, depending on multiple possibilities. So categories of possibility and actuality in the foundations of scientific theories need special attention. Now it touches upon at least two moments: the virtual particles as abstract objects of relativistic quantum theories and to the problem of understanding the ontological status of category "matter" in foundations of many world cosmology in the context of relations to categories "possibility", "actuality" and "reality".

Abstract:

String/M-theory is an exciting framework within which we try to understand our universe and its properties. Compactified string/M-theories address and offer solutions to almost every important question and issue in particle physics and particle cosmology. But earlier goals of finding a top–down “vacuum selection” principle and deriving the 4D theory have not yet been realized. Does that mean we should stop trying, as nearly all string theorists have? Or can we proceed in the historical way to make a few generic, robust assumptions not closely related to observables, and follow where they lead to testable predictions and explanations? Making only very generic assumptions is a significant issue. I discuss how to try to proceed with this approach, particularly in M-theory compactified on a 7D manifold of G2 holonomy. One goal is to understand our universe as a string/M-theory vacuum for its own sake, in the long tradition of trying to understand our world, and what that implies. In addition, understanding our vacuum may be a prelude to understanding its connection to the multiverse.

Abstract:

This paper addresses the optimal power flow problem in direct current (DC) networks employing a master–slave solution methodology that combines an optimization algorithm based on the multiverse theory (master stage) and the numerical method of successive approximation (slave stage). The master stage proposes power levels to be injected by each distributed generator in the DC network, and the slave stage evaluates the impact of each power configuration (proposed by the master stage) on the objective function and the set of constraints that compose the problem. In this study, the objective function is the reduction of electrical power losses associated with energy transmission. In addition, the constraints are the global power balance, nodal voltage limits, current limits, and a maximum level of penetration of distributed generators. In order to validate the robustness and repeatability of the solution, this study used four other optimization methods that have been reported in the specialized literature to solve the problem addressed here: ant lion optimization, particle swarm optimization, continuous genetic algorithm, and black hole optimization algorithm. All of them employed the method based on successive approximation to solve the load flow problem (slave stage). The 21- and 69-node test systems were used for this purpose, enabling the distributed generators to inject 20%, 40%, and 60% of the power provided by the slack node in a scenario without distributed generation. The results revealed that the multiverse optimizer offers the best solution quality and repeatability in networks of different sizes with several penetration levels of distributed power generation.

Abstract:

In this paper, we study the gauge invariance of the third quantized supergroup field cosmology which is a model for multiverse. Further, we propose both the infinitesimal (usual) as well as the finite superfield-dependent BRST symmetry transformations which leave the effective theory invariant. The effects of finite superfield-dependent BRST transformations on the path integral (so-called void functional in the case of third quantization) are implemented. Within the finite superfield-dependent BRST formulation, the finite superfield-dependent BRST transformations with specific parameter switch the void functional from one gauge to another. We establish this result for the most general gauge with the help of explicit calculations which holds for all possible sets of gauge choices at both the classical and the quantum levels.

Abstract:

At a meeting in Leningrad in December 1948, Soviet astronomers affirmed the need to fight against the “reactionary-idealistic” theory of a “primeval atom.” Support for this theory, later dubbed the “Big Bang” by one of its fiercest critics, would, the Soviets claimed, help clericalism.1 While such anxieties might seem astonishing today, they may have seemed plausible in the 1940s, especially since the theory had first been proposed by a Catholic priest, Father Georges Lemaître. Furthermore, while Lemaître himself was careful to avoid drawing theological inferences, the association of his theory with the religious doctrine of Creation, especially by Pope Pius XII in 1951, helped to motivate the search for alternative approaches such as the “steady-state” theory.2 In recent years, by contrast, the perception has been growing that the Big Bang theory has ceased to be offensive to atheist sensibilities. It is claimed that the Big Bang can now be accommodated safely within a self-sufficient system of natural causes, possibly by embedding the universe within an infinitely larger and eternal “multiverse.” Indeed, just a few months ago, the media reported with enthusiasm the assertions made by Stephen Hawking in his latest book, that contemporary physics has solved the mysteries of the Big Bang making recourse to God obsolete.3

Abstract:

In the string landscape picture, the effective potential is characterized by an enormous number of local minima of which only a minuscule fraction are suitable for the evolution of life. In this "multiverse", random transitions are continually made between the various minima with the most likely transitions being to minima of lower vacuum energy. The inflationary era in the very early universe ended with such a transition to our current phase which is described by a broken supersymmetry and a small, positive vacuum energy. However, it is likely that an exactly supersymmetric (susy) phase of zero vacuum energy as in the original superstring theory also exists and that, at some time in the future, there will be a transition to this susy world. In this article we make some preliminary estimates of the consequences of such a transition.

Abstract:

Abstract Twentieth-century drama has made the stage a site for reflecting on science. Michael Frayn’s Copenhagen, considered by many as one of the most striking contributions to “science plays,” portrays the elusive yet crucial short meeting of the two pillars of quantum physics, Niels Bohr and Werner Heisenberg, in the autumn of 1941. The play employs ‘real’ scientists as characters that recurrently refer to and explain their scientific ideas such as uncertainty and complementarity, recognized as the Copenhagen Interpretation. Adopting the approach of possible worlds theory, this article analyses the concept of ‘possible worlds’ as projected in Copenhagen in light of the idea that physics itself has proposed a proliferation of parallel universes (multiverse). In fact, our main thesis is that the play offers an alternate history and brings about a myriad of counterfactuals that are tested as “drafts.”

Abstract:

This paper deals with the multi-objective optimization dispatch (MOOD) problem in a DC microgrid. The aim is to formulate the MOOD to simultaneously minimize the operating cost, pollutant emission level of (NOx, SO2 and CO2) and the power loss of conversion devices. Taking into account the equality and inequality constraints of the system. Two approaches have been adopted to solve the MOOD issue. The scalarization approach is first introduced, which combines the weighted sum method with price penalty factor to aggregate objective functions and obtain Pareto optimal solutions. Whilst, the Pareto approach is based on the implementation of evolutionary multi-objective optimization solution. Single and multi-objective versions of multi-verse optimizer algorithm are, respectively, employed in both approaches to handle the MOOD. For each time step, a fuzzy set theory is selected to find the best compromise solution in the Pareto optimal set. The simulation results reveal that the Pareto approach achieves the best performances with a considerable decrease of 28.96 $/day in the daily operating cost, a slight reduction in the power loss of conversion devices from 419.79 kWh to 419.29 kWh, and in less computational time. While, it is noticing a small increment in the pollutant emission level from 11.54 kg/day to 12.21 kg/day, for the daily microgrid operation. This deviation can be fully covered when comparing the cost related to the treatment of these pollutants, which is only 5.55 $/day, to the significant reduction in the operating cost obtained using the Pareto approach.

Abstract:

We give an evidence of the Big Fix. The theory of wormholes and multiverse suggests that the parameters of the Standard Model are fixed in such a way that the total entropy at the late stage of the universe is maximized, which we call the maximum entropy principle. In this paper, we discuss how it can be confirmed by the experimental data, and we show that it is indeed true for the Higgs vacuum expectation value vh. We assume that the baryon number is produced by the sphaleron process, and that the current quark masses, the gauge couplings and the Higgs self-coupling are fixed when we vary vh. It turns out that the existence of the atomic nuclei plays a crucial role to maximize the entropy. This is reminiscent of the anthropic principle, however it is required by the fundamental law in our case.
