The paper discusses the origin of dark matter and dark energy from the concepts of time and the totality in the final analysis. Though both seem to be rather philosophical, nonetheless they are postulated axiomatically and interpreted physically, and the corresponding philosophical transcendentalism serves heuristically. The exposition of the article means to outline the “forest for the trees”, however, in an absolutely rigorous mathematical way, which to be explicated in detail in a future paper. The “two deductions” (...) are two successive stage of a single conclusion mentioned above. The concept of “transcendental invariance” meaning ontologically and physically interpreting the mathematical equivalence of the axiom of choice and the well-ordering “theorem” is utilized again. Then, time arrow is a corollary from that transcendental invariance, and in turn, it implies quantum information conservation as the Noether correlate of the linear “increase of time” after time arrow. Quantum information conservation implies a few fundamental corollaries such as the “conservation of energy conservation” in quantum mechanics from reasons quite different from those in classical mechanics and physics as well as the “absence of hidden variables” (versus Einstein’s conjecture) in it. However, the paper is concentrated only into the inference of another corollary from quantum information conservation, namely, dark matter and dark energy being due to entanglement, and thus and in the final analysis, to the conservation of quantum information, however observed experimentally only on the “cognitive screen” of “Mach’s principle” in Einstein’s general relativity. therefore excluding any other source of gravitational field than mass and gravity. Then, if quantum information by itself would generate a certain nonzero gravitational field, it will be depicted on the same screen as certain masses and energies distributed in space-time, and most presumably, observable as those dark energy and dark matter predominating in the universe as about 96% of its energy and matter quite unexpectedly for physics and the scientific worldview nowadays. Besides on the cognitive screen of general relativity, entanglement is available necessarily on still one “cognitive screen” (namely, that of quantum mechanics), being furthermore “flat”. Most probably, that projection is confinement, a mysterious and ad hoc added interaction along with the fundamental tree ones of the Standard model being even inconsistent to them conceptually, as far as it need differ the local space from the global space being definable only as a relation between them (similar to entanglement). So, entanglement is able to link the gravity of general relativity to the confinement of the Standard model as its projections of the “cognitive screens” of those two fundamental physical theories.

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)

Current cosmological observations place little constraints on the nature of dark matter, allowing the development of a large number of models and various methods for probing their properties, which seem to provide ideal grounds for the employment of robustness arguments. In this article, the extent to which such arguments can be used to overcome various methodological and theoretical challenges is examined. The conclusion is that while robustness arguments have a limited scope in the context of dark (...) class='Hi'>matter research, they can still be used for increasing the scientists’ confidence about the properties of specific models.

Paul Feyerabend argued that theories can be faced with experimental anomalies whose refuting character can only be recognized by developing alternatives to the theory. The alternate theory must explain the experimental results without contrivance and it must also be supported by independent evidence. I show that the situation described by Feyerabend arises again and again in experiments or observations that test the postulates in the standard cosmological model relating to dark matter. The alternate theory is Milgrom’s modified dynamics. (...) I discuss three examples: the failure to detect dark-matter particles in laboratory experiments; the lack of evidence for dark-matter sub-haloes and the dwarf galaxies that are postulated to inhabit them; and the failure to confirm the predicted orbital decay of Milky Way satellite galaxies and other systems due to dynamical friction against the dark matter. In each case, Feyerabend’s criterion directs us to interpret the experimental or observational results as an indirect refutation of the standard cosmological model in favor of Milgrom’s theory.

Baker argues that quantitative parsimony—the principle that hypotheses requiring fewer entities are to be preferred over their empirically equivalent rivals—is a rational methodological criterion because it maximizes explanatory power. Baker lends plausibility to his account by confronting it with the example of postulating of the neutrino in order to resolve a discrepancy in Beta decay experiments. Baker’s account is initially attractive, but I argue that its details are problematic and that it yields undesirable consequences when applied to the case of (...) astrophysical dark matter. Baker has not succeeded in showing why quantitative parsimony is a theoretical virtue. (shrink)

A model of a three-dimensional quantum vacuum based on Planck energy density as a universal property of a granular space is suggested. The possibility to provide an unifying explanation of dark matter and dark energy as phenomena linked with the fluctuations of the three-dimensional quantum vacuum is explored. The changes and fluctuations of the quantum vacuum energy density generate a curvature of space–time similar to the curvature produced by a “dark energy” density. The formation of large (...) scale structures in the universe associated to the flattening of the orbital speeds of the spiral galaxies can be explained in terms of primary fluctuations of the quantum vacuum energy density without attracting the idea of dark matter.

To a packed audience in Clark Hall, Sheila Jasanoff, a distinguished scholar and former president of the Society for Social Studies of Science, gave the plenary address for “Where has STS Traveled,” a commemorative gathering of the fortieth anniversary of the inaugural meeting of the 4S. Not only was this meeting located in the very same room as the first gathering, but also many of the original members had traveled from far and wide to Cornell University to reminisce and reflect (...) on the academic field they had established, as well as imagine the possibilities of the next forty years. In response to a question about the direction of STS, Professor Jasanoff suggested that the 4S had not turned its reflective gaze inward to examine the politics of its own society, nor had it spent much effort interrogating the society’s contribution to social policy or enduring social problems. As I heard Jasanoff speak about our collective need for reflection and reflexivity, I had to wonder whether, and to what extent, we were ready to reflect on the subject matter of race and racism in this mostly color-blind field of inquiry.

It is suggested that the apparently disparate cosmological phenomena attributed to so-called ‘dark matter’ and ‘dark energy’ arise from the same fundamental physical process: the emergence, from the quantum level, of spacetime itself. This creation of spacetime results in metric expansion around mass points in addition to the usual curvature due to stress-energy sources of the gravitational field. A recent modification of Einstein’s theory of general relativity by Chadwick, Hodgkinson, and McDonald incorporating spacetime expansion around mass points, (...) which accounts well for the observed galactic rotation curves, is adduced in support of the proposal. Recent observational evidence corroborates a prediction of the model that the apparent amount of ‘dark matter’ increases with the age of the universe. In addition, the proposal leads to the same result for the small but nonvanishing cosmological constant, related to ‘dark energy,’ as that of the causet model of Sorkin et al. (shrink)

An intellectual history of the philosophers who grappled with the problem of evil, and the case for why pessimism still holds moral value for us today In the seventeenth and eighteenth centuries, philosophers engaged in heated debates on the question of how God could have allowed evil and suffering in a creation that is supposedly good. Dark Matters traces how the competing philosophical traditions of optimism and pessimism arose from early modern debates about the problem of evil, and makes (...) a compelling case for the rediscovery of pessimism as a source for compassion, consolation, and perhaps even hope. Bringing to life one of the most vibrant eras in the history of philosophy, Mara van der Lugt discusses legendary figures such as Leibniz, Hume, Voltaire, Rousseau, Kant, and Schopenhauer. She also introduces readers to less familiar names, such as Bayle, King, La Mettrie, and Maupertuis. Van der Lugt describes not only how the earliest optimists and pessimists were deeply concerned with finding an answer to the question of the value of existence that does justice to the reality of human suffering, but also how they were fundamentally divided over what such an answer should look like. A breathtaking work of intellectual history by one of today's leading scholars, Dark Matters reveals how the crucial moral aim of pessimism is to find a way of speaking about suffering that offers consolation and does justice to the fragility of life.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Dark Matters: Pessimism and the Problem of Suffering by Mara van der LugtStefano BrogiMara van der Lugt. Dark Matters: Pessimism and the Problem of Suffering. Princeton, NJ: Princeton University Press, 2021. Pp. xi + 450. Hardback, $37.00.Mara van der Lugt's book (awarded Honorable Mention for the JHP Book Prize in 2022) has the merit of bringing attention to some crucial yet often overlooked topics by providing (...) a contribution that cannot fail to elicit broad interest. Her book does not simply discuss the theodicy and anti-theodicy of the modern age; against this background, she also brings out the often-ignored tradition of philosophical pessimism. What interests van der Lugt, however, is not "future-oriented" pessimism, which is opposed to "progressivist" theories of history, but an ontological or "value-oriented" pessimism that stresses "the terrible side of [End Page 163] life" in order to answer a series of crucial questions in a way very different from Leibniz's or Pope's approaches: Are there more evils than goods in our lives? Is life worth living for all of us, for any of us? Why do some people choose death despite their blessings? Why do some people choose life despite their sufferings? Do animals suffer as we do? Are we responsible for our own happiness? Is it better never to have been? According to van der Lugt, "The various ways in which these questions have been answered throughout the centuries have created the competing philosophical traditions known as optimism and pessimism. This book traces the intersection of the debate on the problem of evil with the debate on pessimism from the late seventeenth century onwards, seeking throughout to evaluate pessimism on its own terms" (20).A reassessment of this kind of pessimism serves an explicitly theoretical and moral purpose: van der Lugt herself states that her book is not exclusively a contribution to the history of philosophy, but "partly ethical or evaluative" (18). Indeed, pessimism and optimism "go hand in hand": they stem from a moral need and aim to respond to the evil present in the world by opening up glimmers of "hope, compassion, and consolation" (12, emphasis in original). Pessimism, in particular, is not intended to be "a philosophy of despair"; rather, it draws its strength from an "ethical commitment." Stemming from the latter is a tradition that "may be reinterpreted as a moral source" (22) and which "has not only its own epistemological and methodological concerns and presuppositions but, crucially, its own sets of virtues and moral aims" (13).The theoretical/moral purpose of Dark Matters is evident through its unfolding, even though eight of its nine chapters are roughly devoted to providing an accurate historical-philosophical reconstruction. Here, in brief, are the titles of the chapters that make up the over four hundred pages of this volume, which provide a good idea of the main authors discussed: (1) "The Complaint: Bayle and Malebranche on Physical Evil"; (2) "The Optics of Optimism: Leibniz and King Respond to Bayle"; (3) "Of Hope and Consolation: Voltaire and the Deists"; (4) "When Stoicism Meets Pessimism: La Mettrie and Maupertuis"; (5) "The Dispositional Problem of Evil: David Hume"; (6) "The Art of Suffering: Jean-Jacques Rousseau"; (7) "The Failure of Theodicy: Immanuel Kant"; (8) "The Flute-Playing Pessimist: Arthur Schopenhauer"; and (9) "Dark Matters: Pessimism as a Moral Source." To some extent, the rich itinerary provided by van der Lugt may be compared to those studies that have long undermined the idea of a monolithic and compact Enlightenment, characterized by unlimited faith in reason and its potential for liberation, and—more specifically—by a fundamental optimism with regard to human nature and the possibility of reformulating social and political structures in such a way as to enable each person to pursue happiness. However, the historical reconstruction provided here is based on an attempt to bring out the recurrent theoretical core of a philosophical perspective that first emerges with Pierre Bayle and runs through the modern and contemporary age, resurfacing in an evident way in the present-day antinatalism of David Benatar (often cited in the footnotes).According to van der Lugt, it is with Bayle (and not...

This dissertation examines the dynamical dark matter problem in twentieth century astrophysics from the point of view of History and Philosophy of Science. The dynamical dark matter problem describes the situation astronomers find themselves in with regard to the dynamics of large scale astrophysical systems such as galaxies and galaxy clusters: The observed motions are incompatible with the visible distribution matter given the accepted law of gravitation. This discrepancy has two classes of possible solutions: either (...) there exists copious amounts of some kind of matter that neither emits nor absorbs radiation , or the law of gravitation must be revised. ;Chapter 2 describes the physical and philosophical foundations of dynamical inferences---inferences from discrepancies between well-founded theoretical expectations and reliable observations to the characteristics of candidate solutions. Chapter 3 discusses the history of dark matter . Chapter 4 reviews the present evidence bearing on the dark matter problem. Chapter 5 evaluates the important candidate matter solutions in light of the available evidence. Chapter 6 evaluates two candidate gravitational solutions on evidential and methodological grounds, and addresses the problem of theory choice. I do not try to solve the dark matter problem, but to uncover and evaluate patterns of inference involved in evidential arguments for and against candidate solutions. ;I show that Newton's "Reasoning from Phenomena" is a good framework from which to understand what is going on in this field. I argue that "higher order" and especially non-dynamical evidence is the best hope for solving this problem in dynamics. This is so in part because of "the dark matter double bind": the very existence of the dark matter problem means that we cannot be sure of the overall matter distribution in astrophysical systems, and this in turn means that the observed motions by themselves cannot provide relative confirmation of any theory of gravitational interactions taking place at these scales. I use Newton's Rules of Reasoning to argue that we should retain General Relativity as our theory of gravity at galactic and greater scales, despite the lack of positive evidence to confirm it over its rivals at these scales.

Dark matter is an essential ingredient of the present Standard Cosmological Model, according to which only 5% of the mass/energy content of our universe is made of ordinary matter. In recent times, it has been argued that certain cases of gravitational lensing represent a new type of evidence for the existence of DM. In a recent paper, Peter Kosso attempts to substantiate that claim. His argument is that, although in such cases DM is only detected by its (...) gravitational effects, gravitational lensing is a direct consequence of Einstein's Equivalence Principle and therefore the complete gravitational theory is not needed in order to derive such lensing effects. In this paper I critically examine Kosso's argument: I confront the notion of empirical evidence involved in the discussion and argue that EEP does not have enough power by itself to sustain the claim that gravitational lensing in the Bullet Cluster constitutes evidence for the DM Hypothesis. As a consequence of this, it is necessary to examine the details of alternative theories of gravity to decide whether certain empirical situations are indeed evidence for the existence of DM. It may well be correct that gravitational lensing does constitute evidence for the DM Hypothesis—at present it is controversial whether the proposed modifications of gravitation all need DM to account for the phenomenon of gravitational lensing and if so, of which kind—but this will not be a direct consequence of EEP.

Unravelling the thought of Alexander Kluge and Oskar Negt Collaborators for more than four decades, lawyer, author, filmmaker, and multimedia artist Alexander Kluge and social philosopher Oskar Negt are an exceptional duo in the history of Critical Theory precisely because their respective disciplines think so differently. Dark Matter argues that what makes their contributions to the Frankfurt School so remarkable is how they think together in spite of these differences. Kluge and Negt's "gravitational thinking" balances not only the (...) abstractions of theory with the concreteness of the aesthetic, but also their allegiances to Frankfurt School mentors with their fascination for other German, French, and Anglo-American thinkers distinctly outside the Frankfurt tradition. At the core of all their adventures in gravitational thinking is a profound sense that the catastrophic conditions of modern life are not humankind's unalterable fate. In opposition to modernity's disastrous state of affairs, Kluge and Negt regard the huge mass of dark matter throughout the universe as the lodestar for thinking together with others, for dark matter is that absolute guarantee that happier alternatives to our calamitous world are possible. As illustrated throughout Langston's study, dark matter's promise--its critical orientation out of catastrophic modernity--finds its expression, above all, in Kluge's multimedia aesthetic. (shrink)

It is suggested that the dark matter of the universe is due to the presence of a scalar field described by the gauge function introduced by Dirac in his modification of the Weyl geometry. The behavior of such dark matter is investigated.

The unreduced many-body interaction problem solution, absent in usual science framework, reveals a new quality of emerging multiple, equally real but mutually incompatible system configurations, or “realisations”, giving rise to the universal concept of dynamic complexity and chaoticity. Their imitation by a single, “average” realisation or trajectory in usual theory (corresponding to postulated “exact” or perturbative problem solutions) is a rough simplification of reality underlying all stagnating and emerging problems of conventional (unitary) science, often in the form of missing, or (...) “dark”, entities and “hidden variables”. We show how the application of unreduced interaction problem solution and the ensuing concept of dynamic complexity provides the desired causally complete and intrinsically unified solutions to respective unitary science problems in the entire range of complexity levels, from elementary particles and cosmology to emergent consciousness and modern development crisis, implying real, essential and urgently needed progress.

This paper scrutinises the tenability of a strict conceptual distinction between space and matter via the lens of the debate between modified gravity and dark matter. In particular, we consider Berezhiani and Khoury's novel 'superfluid dark matter theory' as a case study. Two families of criteria for being matter and being spacetime, respectively, are extracted from the literature. Evaluation of the new scalar field postulated by SFDM according to these criteria reveals that it is (...) as much matter as anything could possibly be, but alsoꟷbelow the critical temperature for superfluidityꟷas much spacetime as anything could possibly be. A sequel paper examines possible interpretations of SFDM in light of this result, as well as the consequences for our understanding of the modified gravity/ dark matter distinction and the broader spacetime–matter distinction.

The evidence of the phenomenon for which, in galaxies, the gravitating mass is distributed differently than the luminous mass, increases as new data become available. Furthermore, this discrepancy is well structured and it depends on the magnitude and the compactness of the galaxy and on the radius, in units of its luminous size \, where the measure is performed. For the disk systems with \ all this leads to an amazing scenario, revealed by the investigation of individual and coadded rotation (...) curves, according to which, the circular velocity follows, from their centers out to their virial radii, an universal profile \\) function only of the properties of the luminous mass component. Moreover, from the Universal Rotation Curve, so as from many individual high quality RCs, we discover that, in the innermost regions of galaxies, the DM halo density profiles are very shallow. Finally, the disk mass, the central halo density and its core radius, come out all related to each other and to two properties of the distribution of light in galaxies: the luminosity and the compactness. This phenomenology, being absent in the simplest \ Cosmology scenario, poses serious challenges to the latter or, alternatively, it requires a substantial and tuned involvement of baryons in the formation of the galactic halos. On the other side, the URC helps to explain the two-accelerations relationship found by McGaugh et al., in terms of only well known astrophysical processes, acting in a standard DM halos + luminous disks scenario.

Empirical and theoretical evidence show that the astrophysical problem of dark matter might be solved by a theory of Einstein-Mayer type. In this theory, up to global Lorentz rotations, the reference system is determined by the motion of cosmic matter. Thus, one is led to a “Riemannian space with teleparallelism” realizing a geometric version of the Mach-Einstein doctrine. The field equations of this gravitational theory contain hidden matter terms, where the existence of hidden matter is (...) inferred solely from its gravitational effects. It is argued that, in the nonrelativistic mechanical approximation, they provide an inertia-free mechanics, where the inertial mass of a body is induced by the gravitational action of the comic masses. Interpreted from the Newtonian point of view, this mechanics shows that the effective gravitational mass of astrophysical objects depends on r such that one expects the existence of dark matter.

Der Beitrag diskutiert das Verhältnis zwischen Experiment und Ästhetik, indem er von zwei zeitgenössischen künstlerischen Erfahrungen ausgeht: Der Ausstellung SOMA von Carsten Höller, die im Hamburger Bahnhof in Berlin im Winter 2010/11 gezeigt wurde, und einem Clip der Performance Dark Matter von Kate McIntosh. Beide Werke stellen das Experiment im Kontext der Künste zur Debatte und führen gleichzeitig zur Vervielfältigung seiner Bedeutung. SOMA stellt ›Spiele des Sehens‹ vor, die den ästhetischen Charakter eines Experimentes und die ›miseen-scène‹ verschiedener Situationen (...) der Beobachtung prüfen. Dark Matter spielt auf wissenschaftliche Ordnungen der Präsentation an und zieht die Aufmerksamkeit des Zuschauers auf die Dramaturgie des Experiments, das Raum für neue Methoden der Mobilisierung oder Korrelierung macht.

SOMA provides ›games of seeing‹ testing the aesthetic character of an experiment’s architecture and the ›mise-en-scène‹ of different situations of observation. Dark Matter plays upon scientific orders of presentation dragging the spectator’s attention to the dramaturgy of the experiment, which makes space for a new methods of mobilization or correlation.

Recent attempts to explain the dark matter and energy content of the universe have involved some radical extensions of standard physics, including quintessence, phantom energy, additional space dimensions, and variations in the speed of light. In this paper I consider the possibility that some dark matter might be in the form of tachyons. I show that, subject to some reasonable assumptions, a tachyonic cosmological fluid would produce distinctive effects, such as a surge in quantum vacuum energy (...) and particle creation, and a change in the conventional temperature–time relation for the normal cosmological material.

It is thus tempting to adopt scientific realism about dark matter. However, there are barely any constraints on the myriad of possible properties of (...) this entity—it is not even certain that it is a form of matter. In light of this underdetermination I advocate caution: we should not (yet) be dark matter realists. The “not(-yet)-realism” that I have in mind is different from Hacking’s (Philos Sci 56 (4), 555–581, 1989) anti-realism, in that it is semantic rather than epistemological. It also differs from the semantic anti-realism of logical empiricism, in that it is naturalistic, such that it may only be temporary and does not automatically apply to all other unobservables (or even just to all other astronomical unobservables, as with Hacking’s anti-realism). The argument is illustrated with the analogy of the much longer history of the concept of a gene, as the current state of the concept of dark matter resembles in some relevant ways that of the early concept of genes.

This book is an exploration of interrelationships among culture, language, and the individual unconscious (the "dark matter of the mind”), how these feed into a sense of self, and implications for the notion of "human nature.” The first part of the book is concerned with perceptual and cultural bases of dark matter and the effect of dark matter on perception (especially vision) and the interpretation of discourse. The second part is concerned with the contribution (...) of dark matter to language--with language viewed as a combination of speech and gesture, and including issues related to translation. In the final part Everett addresses implications of his account, summarizing and extending arguments for replacing an instinct-based account of human nature with a culturally-based, dark matter view of the "constructed self.” Everett makes a powerful argument for the influence of culture on unconscious forces that underlie human behavior and the individual’s sense of self, with much of the power of the argument coming from the deep insights he gained from living and working with the Pirahãs of the Amazon. This is an important book that sits at the intersection of anthropology, linguistics, psychology, and philosophy, and it is enriched by a combination of the author’s knowledge of these fields and his cross-cultural perspective. The book will make an important contribution to newly emerging directions taken by cognitive science. After decades of a field derailed by ethnocentric, instinct-based views of language and the mind, the cognitive sciences need such informed analyses of the relationship between culture, cognition, and language, as embodied in speech and gesture.

We develop a theoretical model involving religiosity [intrinsic (I), extrinsic-social (E s), and extrinsic-personal (E p), Time 1], Machiavellianism (Time 2), and propensity to engage in unethical behavior (Time 2) to investigate direct and indirect paths. We collected two-wave panel data from 359 students who had some work experiences. For the whole sample, intrinsic religiosity (I) indirectly curbed unethical intentions through the absence of Machiavellianism, the bright side of religiosity. Both extrinsic-social (E s) and extrinsic-personal (E p) directly, while extrinsic-social (...) (E s) indirectly, exacerbated unethical intentions, the dark side of religiosity. Multiple-group analyses across gender, college major, and income showed that the bright side existed directly for low-income students, but indirectly for males and females, business majors, and low-income students. Our novel finding showed that E p undermined unethical intentions indirectly for females. For the dark side, E s incited unethical intentions directly for males, business students, and low-income individuals, but indirectly for females, psychology majors, and low-income people. The Machiavellianism–unethical intentions relationship was the strongest for high-income participants. Religiosity had the highest number of significant paths for low-income individuals and the strongest dark side for males and high-income students, but the highest bright outcome for females. Our novel, original findings foster theory development and testing, add new vocabulary to the conversation of religiosity and unethical intentions, and improve practice. (shrink)

We present a new approach to the mathematical objects of General Relativity in terms of which a generic f(R)-gravity theory gravitation is written in a first-order (à la Palatini) formalism, and introduce the concept of Dark Metric which could bypass the emergence of disturbing concepts as Dark Energy and Dark Matter. These issues are related to the fact that General Relativity could not be the definitive theory of Gravitation due to several shortcomings that come out both (...) from theoretical and experimental viewpoints. At large scales, the attempts to match it with the recent observational data lead to invoke Dark Energy and Dark Matter as the bulk components of the cosmic fluid. Since no final evidence, at fundamental level, exists for such ingredients, it could be useful to reconsider the gravitational sector in order to see if suitable extensions of General Relativity could solve the shortcomings present at infrared scales.

This paper pushes back against the Democritean-Newtonian tradition of assuming a strict conceptual dichotomy between spacetime and matter. Our approach proceeds via the more narrow distinction between modified gravity/spacetime and dark matter. A prequel paper argued that the novel field Φ postulated by Berezhiani and Khoury's 'superfluid dark matter theory' is as much matter as anything could possibly be, but also below the critical temperature for superfluidity as much spacetime as anything could possibly be. (...) Here we introduce and critically evaluate three groups of interpretations that one should consider for such Janus-faced theories. The consubstantiality interpretation holds that Φ is both matter and a modification of spacetime, analogously to the sense in which Jesus is both human and god. The fundamendalist interpretations consider for each of these roles whether they are instantiated fundamentally or emergently. The breakdown interpretations focus on the question of whether Φ signals the breakdown, in some sense to be specified, of the MG-DM dichotomy and perhaps even the broader spacetime–matter distinction. More generally, it is argued that hybrid theories urge a move towards a single space of theories, rather than two separate spaces of spacetime theories and matter theories, respectively. (shrink)

The thesis is: the “periodic table” of “dark matter” is equivalent to the standard periodic table of the visible matter being entangled. Thus, it is to consist of all possible entangled states of the atoms of chemical elements as quantum systems. In other words, an atom of any chemical element and as a quantum system, i.e. as a wave function, should be represented as a non-orthogonal in general (i.e. entangled) subspace of the separable complex Hilbert space relevant (...) to the system to which the atom at issue is related as a true part of it. The paper follows previous publications of mine stating that “dark matter” and “dark energy” are projections of arbitrarily entangled states on the cognitive “screen” of Einstein’s “Mach’s principle” in general relativity postulating that gravitational field can be generated only by mass or energy.

When a scientist is the first to perform a difficult type of observation and correctly interprets the result as a significant challenge to then-widely accepted core theories, and the result is later recognized as seminal work in a field of major importance, it is a surprise to find that that work was essentially ignored by the scientific community for thirty years. Such was the fate of the doctoral research on the rotations of the Andromeda Nebula (M31) conducted by Horace Welcome (...) Babcock (1912–2003), who went on to become a very prominent astronomer — in an entirely different sub-field, never working on the subject of his dissertation again. This paper seeks to explain the ‘non-reception’ of Babcock’s work on galactic dynamics and the reasons he did no further work in that sub-field. In particular this paper shows that, contrary to the claims of some commentators, the non-reception of Babcock’s work should not be understood as an example of the unjust treatment of a young scientist by the conservative establishment.

Peter Kosso discusses the weak gravitational lensing observations of the Bullet Cluster and argues that dark matter can be detected in this system solely through the equivalence principle without the need to specify a full theory of gravity. This paper argues that Kosso gets some of the details wrong in his analysis of the implications of the Bullet Cluster observations for the Dark Matter Double Bind and the possibility of constructing robust tests of theories of gravity (...) at galactic and greater scales. Even the Bullet Cluster evidence is not sufficiently detailed to allow precision tests of General Relativity that would distinguish it from its rivals at galactic and greater scales. Taking into account the total evidence available, we cannot rule out “ugly” solutions to the dynamical discrepancy in astrophysics that involve both a large quantity of dark matter and a theory of gravity whose predictions differ significantly from those of General Relativity for interactions taking place at galactic and greater scales.

This paper compares four techniques for measuring the masses of galaxies and larger astrophysical systems from their dynamics. The apparent agreement of these techniques is sometimes invoked as reason for hypothesizing the existence of huge quantities of “dark matter” as the best solution to “the dynamical discrepancy”, the 100-fold disparity between the amount of mass visible in large scale astrophysical systems and the amount calculated from dynamics. This paper argues that the agreement, though suggestive, is not definitive. The (...) coincident measurements remain the best reason for preferring dark matter over revisions to General Relativity for solving the dynamical discrepancy, but the resulting warrant for this preference is weak.

Two approaches have emerged to resolve discrepancies between predictions and observations at galactic and cosmological scales: introducing dark matter or modifying the laws of gravity. Practitioners of each approach claim to better satisfy a different explanatory ideal, either unification or simplicity. In this chapter, we take a closer look at the ideals and at the successes of these approaches in achieving them. Not only are these ideals less divisive than assumed, but moreover we argue that the approaches are (...) focusing on different aspects of the same ideal. This realisation opens up the possibility of a more fruitful trading zone between dark matter and modified gravity communities. (shrink)

The target article's approach is applauded, but it is suggested that the may be much larger than even the current authors suspect. Cartesian and mechanistic assumptions infuse not only the discipline of cognitive psychology, but all societal accounts of the person. A switch to dynamical accounts in which lawfulness is observed within a given systemic context is suggested.
