In this contribution I wish to address the question whether, and how, the global cosmological expansion influences local physics, like particle orbits and black hole geometries. Regarding the former I argue that a pseudo Newtonian picture can be quite accurate if “expansion” is taken to be an attribute of the inertial structure rather than of “space” in some substantivalist sense. This contradicts the often-heard suggestion to imagine cosmological expansion as that of “space itself”. Regarding isolated (...) objects in full General Relativity, like black holes, I emphasise the need for proper geometric characterisations in order to meaningfully compare them in different spacetimes, like static and expanding ones. Examples are discussed in some detail to clearly map out the problems. A slightly extended version of this contribution may be found at philsci-archive.pitt.edu/10033. (shrink)

Accelerating Expansion explores some of the philosophical implications of modern cosmology, focused on the significance that the discovery of the accelerating expansion of the Universe has for our understanding of time, geometry, and physics. The appearance of the cosmological constant in the equations of general relativity allows one to model universes in which space has an inherent tendency towards expansion. This constant, introduced by Einstein but subsequently abandoned by him, returned to centre stage with the discovery (...) of the accelerating expansion. This pedagogically-oriented essay begins with a study of the most basic and elegant relativistic world that involves a positive cosmological constant, de Sitter spacetime. It then turns to the relatives of de Sitter spacetime that dominate modern relativistic cosmology. Some of the topics considered include: the nature of time and simultaneity in de Sitter worlds; the sense in which de Sitter spacetime is a powerful dynamical attractor; the limited extent to which observation can give us information about the topology of space in a world undergoing accelerated expansion; and cosmologists' favourite sceptical worry about the reliability of evidence and the possibility of knowledge, the problem of Boltzmann brains.

We review Gordon Belot’s ‘Accelerating Expansion: Philosophy and Physics with a Positive Cosmological Constant’ (OUP, 2023).

Macroscopic irreversible processes emerge from fundamental physical laws of reversible character. The source of the local irreversibility seems to be not in the laws themselves but in the initial and boundary conditions of the equations that represent the laws. In this work we propose that the screening of currents by black hole event horizons determines, locally, a preferred direction for the flux of electromagnetic energy. We study the growth of black hole event horizons due to the cosmological expansion (...) and accretion of cosmic microwave background radiation, for different cosmological models. We propose generalized McVittie co-moving metrics and integrate the rate of accretion of cosmic microwave background radiation onto a supermassive black hole over cosmic time. We find that for flat, open, and closed Friedmann cosmological models, the ratio of the total area of the black hole event horizons with respect to the area of a radial co-moving space-like hypersurface always increases. Since accretion of cosmic radiation sets an absolute lower limit to the total matter accreted by black holes, this implies that the causal past and future are not mirror symmetric for any spacetime event. The asymmetry causes a net Poynting flux in the global future direction; the latter is in turn related to the ever increasing thermodynamic entropy. Thus, we expose a connection between four different “time arrows”: cosmological, electromagnetic, gravitational, and thermodynamic. (shrink)

Cosmology, the study of the universe, has a past, which is reviewed here. The standard model—the Big Bang, or the hot, dense early universe that is still expanding—is based on observations that are basically consistent but which require additional input to improve the agreement. Out of the early universe came the galaxies and stars that shine today. The future of the universe depends on the density of matter: too much mass leads to the Big Crunch; too little leads to eternal (...) expans ion and cooling. The dark‐matter problem prevents us from knowing which will be the fate of the universe. Thelimits of what may be called “scientific” are addressed. (shrink)

For centuries, the processes of social differentiation associated with Modernity have often been thought to intensify the need for site-specific forms of role training and knowledge production, threatening the university’s survival either through fragmentation or through failure to adapt. Other lines of argument emphasize the extent to which the Modern system creates and relies on an integrated knowledge system, but most of the literature stresses functional differentiation and putative threats to the university. And yet over this period the university has (...) flourished. In our view, this seeming paradox is explained by the fact that modern society rests as much on universalistic cosmological bases as it does on differentiation. The university expands over recent centuries because – as it has from its religious origins – it casts cultural and human materials in universalistic terms. Our view helps explain empirical phenomena that confound standard accounts: the university’s extraordinary expansion and global diffusion, its curricular and structural isomorphism, and its relatively unified structure. All of this holds increasingly true after World War II, as national state societies made up of citizens are increasingly embedded in a world society constituted of empowered individuals. The redefinition of society in global and individual terms reduces nationally bounded models of nature and culture, extends the pool of university beneficiaries and investigators, and empowers the human persons who are understood to root it all. The changes intensify universalization and the university’s rate of worldwide growth. For the university’s knowledge and “knowers,” and for the pedagogy that joins them together, the implications are many. The emerging societal context intensifies longstanding processes of cultural rationalization and ontological elaboration, yielding great expansions in what can and should be known, and in who can and should know. These changes in turn alter the menu of approved techniques for joining knowledge and knower as one. The “knowledge society” that results is distinguished by the extraordinary degree to which the university is linked to society. But it is also distinguished by the degree to which society is organized around the university’s abstracted and universalized understandings of the world and its degree-certified graduates. (shrink)

In this paper we summarise the constraints that low-redshift data—such as supernovae Ia, baryon acoustic oscillations and cosmic chronometers —are able to set on the concordance model and its extensions, as well as on inhomogeneous but isotropic models. We provide a broad overlook into these cosmological scenarios and several aspects of data analysis. In particular, we review a number of systematic issues of SN Ia analysis that include magnitude correction techniques, selection bias and their influence on the inferred (...) class='Hi'>cosmological constraints. Furthermore, we examine the isotropic and anisotropic components of the BAO data and their individual relevance for cosmological model-fitting. We extend the discussion presented in earlier works regarding the inferred dynamics of cosmic expansion and its present rate from the low-redshift data. Specifically, we discuss the cosmological constraints on the accelerated expansion and related model-selections. In addition, we extensively talk about the Hubble constant problem, then focus on the low-redshift data constraint on \ that is based on CC. Finally, we present the way in which this result compares to the high-redshift \ estimate and local measurements that are in tension. (shrink)

During the nineteenth and early twentieth centuries, a wide variety of American writers proposed the existence of energies connecting human beings to cosmic processes. From varying points of view--scientific, philosophical, religious, and literary--they suggested that such energies would eventually result in the perfection of individual and collective bodies, assuming that assimilation into larger networks of being meant the expansion of humanity's powers and potentialities--a belief that continues to inform much posthumanist theory today. Universes without Us explores a lesser-known countertradition (...) in American literature. As Matthew A. Taylor's incisive readings reveal, the heterodox cosmologies of Edgar Allan Poe, Henry Adams, Charles Chesnutt, and Zora Neale Hurston reject the anthropocentric fantasy that sees the universe as a kind of reservoir of self-realization. For these authors, the world can be made neither "other" nor "mirror." Instead, humans are enmeshed with "alien" processes that are both constitutive and destructive of "us." By envisioning universes no longer our own, these cosmologies picture a form of interconnectedness that denies any human ability to master it. Universes without Us demonstrates how the questions, possibilities, and dangers raised by the posthuman appeared nearly two centuries ago. Taylor finds in these works an untimely engagement with posthumanism, particularly in their imagining of universes in which humans are only one category of heterogeneous thing in a vast array of species, objects, and forces. He shows how posthumanist theory can illuminate American literary texts and how those texts might, in turn, prompt a reassessment of posthumanist theory. By understanding the posthuman as a materialist cosmology rather than a technological innovation, Taylor extends the range of thinkers who can be included in contemporary conversations about the posthuman.

The standard model of cosmology is acclaimed in physics as accurate, robust, well-tested, our best scientific theory of the cosmos, but it has had serious anomalies for a while, including the Hubble tension, anomalous galaxies, and the completely unexplained nature of dark energy and dark matter. And lurking behind it all is the lack of a unified theory: General Relativity (GR) and quantum mechanics (QM) are inconsistent. Now startling new observations by the James Webb Space Telescope (JWST) in 2022 of (...) the early universe present the strongest challenge yet to the standard model, and whispers have started that this shows there is something wrong with the fundamental theory, General Relativity itself. This would be a crisis for cosmology. But haven’t they tested this theory already, and shown it is correct? How could it turn out wrong at this late stage? Here we compare the standard cosmology with an alternative fundamental theory, that has a strikingly different overall cosmological behavior: a simple cyclic expansion function. It is simple and deterministic. There are only two or three general parameters. The interesting result is that this alternative cosmology: (A) closely matches the expansion observed and modelled through the CDM standard model, now going back to red-shifts of 5-15; and (B) it also predicts unexpected early galaxy formation now being reported by the JWST. The point here is not to try to prove this alternative theory however, but rather show how it compares to the conventional cosmology. This show us clearly how weak the empirical evidence for the standard model really is against a counterfactual fundamental theory. Some results established in science are robust against theory change, but we find the standard cosmological model and the implications drawn from it are not robust at all. (shrink)

Abstract I develop the idea that there exists a special dimension of depth, or of scale. The depth dimension is physically real and extends from the bottom micro-level to the ultimate macro-level of the Universe. The depth dimension, or the scales axis, complements the standard three spatial dimensions. I discuss the tentative qualities of the depth dimension and the universal arrangement of matter along this dimension. I suggest that all matter in the Universe, at least in the present cosmological (...) epoch, is in joint downward motion along the depth dimension. The joint downward motion manifests itself in the universal contraction of matter. The opposite direction of motion, upward the dimension, would cause the expansion of matter. The contraction of matter is a primary factor, whereas the shrinking of space in the vicinity of matter is a derivative phenomenon. The observed expansion of the Universe is explained by the fact that celestial bodies become smaller due to matter contraction, while the overall space remains predominantly intact. Thus, relative to the contracting material bodies, the total span of cosmic space appears to be becoming vaster. I attempt to explain how the contraction of matter engenders the effect of universal gravity. I use over thirty animated and graphical color visualizations in the text to make the explanation of the proposed ideas more lucid.

Under the assumption that Hubble's constant H0 is constant in cosmic time, there is an analogy between the equation of propagation of light and that of expansion of the universe. Using this analogy, and assuming that the laws of physics are the same at all cosmic times, a new special relativity, a cosmological relativity, is developed. As a result, a transformation is obtained that relates physical quantities at different cosmic times. In a one-dimensional motion, the new transformation is (...) given by $$x' = \frac{{x - Tv}}{{(1 - T^2 /T_0^2 )^{{1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-\nulldelimiterspace} 2}} }},v' = \frac{{v - xT/T_0^2 }}{{(1 - T^2 /T_0^2 )^{{1 \mathord{\left/ {\vphantom {1 2}} \right. \kern-\nulldelimiterspace} 2}} }}$$ where x and v are the coordinate and velocity, T is the cosmic time measured backward with respect to our present time T=0, tand T0 is Hubble's time.Some consequences of this transformation are given, and its applicability limitation is pointed out.

The debate on the ontological status of spacetime in General Relativity has historically seen two principal philosophical contenders: substantivalism, roughly the view that holds that spacetime exists apart from the material contents of the universe, and relationism, the doctrine that spacetime does not exist, i.e., it is a mere abstract web of spatiotemporal relations among bodies. This dispute, however, has rarely been fought on a cosmological battlefield. In this paper an attempt in this direction is made. The question at (...) issue is the following: is there any feature of our universe that requires or is best explained in terms of a substantival space? I claim that there is indeed: the expansion of the universe, perhaps the most important phenomenon in cosmology, can play such a role. (shrink)

Current popular narratives regarding the history of astronomy espouse the narrative of scientific development arising from clashes between observed phenomena and dogmatic religious scripture. Such narratives consider the development of our understandings of the cosmos as isolated episodes in ground-breaking, world-view shifting events, led by rational, objective and secular observers. As observation of astronomical development in the early 1600s shows, however, such a narrative is false. Developments by Johannes Kepler, for instance, followed earlier efforts by Nicholas Copernicus to refine Aristotelian-based (...) dogma with observed phenomena. Kepler's efforts specifically were not meant to challenge official Church teachings, but offer a superior system to what was than available, based around theological justifications. Popular acceptance of a heliocentric model came not from Kepler's writings, but from the philosophical teachings of Rene Descartes. Through strictly mathematical and philosophical reasoning, Descartes not only rendered the Aristotelian model baseless in society, but also provided a cosmological understanding of the universe that centred our solar system within a vast expanse of other stars. The shift than, from the Aristotelian geocentric model to the heliocentric model, came not from clashes between theology and reason, but from negotiations between theology and observed phenomena.

The Shakespearean image of a tempest and its aftermath forms the beginning as well as a major guiding thread of Logic of Imagination. Moving beyond the horizons of his earlier work, Force of Imagination, John Sallis sets out to unsettle the traditional conception of logic, to mark its limits, and, beyond these limits, to launch another, exorbitant logic—a logic of imagination. Drawing on a vast range of sources, including Plato, Aristotle, Kant, Hegel, Nietzsche, and Freud, as well as developments in (...) modern logic and modern mathematics, Sallis shows how a logic of imagination can disclose the most elemental dimensions of nature and of human existence and how, through dialogue with contemporary astrophysics, it can reopen the project of a philosophical cosmology.

In spite of successful tests, the standard cosmological model, the $$\varLambda$$ CDM model, possesses the most problematic concept: the initial singularity, also known as the big bang. In this paper—by adopting the Kantian difference between to think of an object and to cognize an object—it is proposed a degree of scientificity using fuzzy sets. Thus, the notion of initial singularity will not be conceived of as a scientific issue because it does not belong to the fuzzy set of what (...) is known. Indeed, the problematic concept of singularity is some sort of what Kant called the noumenon, but science, on the other hand, is constructed in the phenomenon. By applying the fuzzy degree of scientificity in cosmological models, one concludes that cosmologies with a contraction phase before the current expansion phase are potentially more scientific than the standard model. At the end of this article, it is shown that Kant’s first antinomy of pure reason indicates a limit to our cosmological models. (shrink)

The successes scored by the big bang model of cosmic evolution in the 1960’s led to an intensive application of quantum theory to the problem of how the expansion might have begun and what its likely first stages were. It seemed as though an incredibly precise setting of the initial conditions would have been needed in order that a long-lived galactic universe containing heavy elements might develop. One response was to suppose that the fine-tuning could somehow be explained by (...) the presence of humans in the universe. This ran quite counter to the traditional supposition, according to which an initial "chaos" was sufficient. This essay outlines the history of the two principles, argues that the so-called "weak" anthropic principle is banal, distinguishes between two sorts of anthropic explanation, and assesses the prospects of the anthropic turn in cosmology.

In the author’s previous contribution to this journal (Rosen 2015), a phenomenological string theory was proposed based on qualitative topology and hypercomplex numbers. The current paper takes this further by delving into the ancient Chinese origin of phenomenological string theory. First, we discover a connection between the Klein bottle, which is crucial to the theory, and the Ho-t’u, a Chinese number archetype central to Taoist cosmology. The two structures are seen to mirror each other in expressing the psychophysical (phenomenological) action (...) pattern at the heart of microphysics. But tackling the question of quantum gravity requires that a whole family of topological dimensions be brought into play. What we find in engaging with these structures is a closely related family of Taoist forebears that, in concert with their successors, provide a blueprint for cosmic evolution. Whereas conventional string theory accounts for the generation of nature’s fundamental forces via a notion of symmetry breaking that is essentially static and thus unable to explain cosmogony successfully, phenomenological/Taoist string theory entails the dialectical interplay of symmetry and asymmetry inherent in the principle of synsymmetry. This dynamic concept of cosmic change is elaborated on in the three concluding sections of the paper. Here, a detailed analysis of cosmogony is offered, first in terms of the theory of dimensional development and its Taoist (yin-yang) counterpart, then in terms of the evolution of the elemental force particles through cycles of expansion and contraction in a spiraling universe. The paper closes by considering the role of the analyst per se in the further evolution of the cosmos. (shrink)

Two literal quotations from Chrysippus’ On Possibles, preserved in Plutarch’s On the Contradictions of the Stoics, seem to contradict the Stoic thesis of the isotropy of the void. According to this thesis the void is an infinite undifferentiated expanse whose center is marked by, and coincides with, the position of the world. Since there is nothing else outside the world, the cohesive force that pervades it is sufficient on its own to guarantee the quasi–indestructibility of the trans–cyclical διακόσμησις and the (...) eternity of the οὐσία. Conversely, in these two quotations Chrysippus maintains that there is a central διαφορά equipped with causal force. This seems to imply the anisotropy of the void. Chrysippus’s view here is also at odds with another official Stoic thesis, i.e. that the incorporeal is causally inert. In this paper it will be argued that there is in fact no contradiction, because, in those two quotations, Chrysippus consciously develops a cosmological hypothesis in order to resolve a difficulty concerning the role of fire during the universal conflagration. Chrysippus’ solution to this difficulty belongs to modal logic and consists in distinguishing between the actual universe and the possible ones. (shrink)

Among the many scholarly surveys of historical and contemporary approaches to Christian eschatology, few treat the relation between eschatology and scientific cosmology. It is the purpose of this essay to do so. I begin with a brief summary of the importance of eschatology to contemporary Christian theology. Next, an overview is given of scientific cosmology, its earlier scenarios for the cosmic far future of “freeze or fry,” and, more recently the discovery that the expansion of the universe is accelerating. (...) These predictions severely challenge those versions of Christian eschatology that are based on the bodily resurrection of Jesus and, by analogy, the transformation of the universe into the new creation. Several recent approaches to this challenge are outlined, including those of Denis Edwards, Jürgen Moltmann, Wolfhart Pannenberg, Ted Peters, John Polkinghorne, and my own. I conclude with some suggestions for future research in both theology and science. (shrink)

According to the standard interpretation of Einstein’s field equations, gravity consists of mass-energy curving spacetime, and an additional physical force or entity—denoted by Λ (the ‘cosmological constant’)—is responsible for the Universe’s metric-expansion. Although General Relativity’s direct predictions have been systematically confirmed, the dominant cosmological model thought to follow from it—the ΛCDM (Lambda cold dark matter) model of the Universe’s history and composition—faces considerable challenges, including various observational anomalies and experimental failures to detect dark matter, dark energy, or (...) inflation-field candidates. This paper shows that Einstein’s Equivalence Principle entails two possible physical interpretations of General Relativity’s field equations. Although the field equations facially appear to support the standard interpretation—that gravity consists of mass-energy curving spacetime—the field equations can be equivalently understood as holding that gravitational effects instead result from mass-energy accelerating the metric-expansion of a second-order spacetime fabric superimposed upon an absolute, first-order Euclidean space, resulting in the observational appearance of spacetime curvature. This alternative interpretation of relativity is shown to be empirically equivalent to the standard interpretation of relativity, albeit with a changing value for Λ (which is similar to how Λ is understood in the conception of Λ as ‘quintessence’, but in this case takes Λ to be gravity). The reconceptualization is then shown to potentially resolve major observational anomalies for the ΛCDM model, including recent observations conflicting with ΛCDM predictions, as well as failures to directly detect dark matter, dark energy, and inflation field/particle candidates.

Scientific cosmology is an empirical discipline whose objects of study are the large-scale properties of the universe. In this context, it is usual to call the direction of the expansion of the universe the "cosmological arrow of time". However, there is no reason for privileging the ‘radius’ of the universe for defining the arrow of time over other geometrical properties of the space-time. Traditional discussions about the arrow of time in general involve the concept of entropy. In the (...) cosmological context, the direction past-to-future is usually related to the direction of the gradient of the entropy function of the universe. But entropy is a thermodynamic magnitude that is typically associated with subsystems of the universe: the entropy of the universe as a whole is a very controversial matter. Moreover, thermodynamics is a phenomenological theory. Geometrical properties of space-time provide a more fundamental and less controversial way of defining an arrow of time for the universe as a whole. We will call the arrow defined only on the basis of the geometrical properties of space-time, independently of any entropic considerations, the "cosmological arrow of time". In this paper we will argue that: (i) it is possible to define a cosmological arrow of time for the universe as a whole, if certain conditions are satisfied, and (ii) the standard models of contemporary cosmology satisfy these conditions.

No other scientist may have had a greater impact on modern cosmology than the Belgian physicist, astronomer and priest Georges Lemaître. In 1927 he predicted the expansion of the universe on the basis of the cosmological field equations; and four years later he proposed what he called the primeval-atom hypothesis, the first version of the later big bang universe. In all his work on cosmology the cosmological constant Λ played a significant role. A recognized expert in the (...) theory of general relativity, Lemaître also contributed significantly to the theoretical clarification of local and global singularity problems. Still, when he died in 1968, at a time when the standard big bang model celebrated its first victories, he was largely forgotten or recalled only as a somewhat shadowy figure of the past. This essay reviews in a historical context the scientific work of Lemaître with particular attention to his seminal contributions in the decade between 1925 and 1934. (shrink)

A new approach to tackle Einstein equations for an isotropic and homogeneous Friedmann–Robertson–Walker Universe in the presence of a quintessence scalar field is devised. It provides a way to get a simple exact solution to these equations. This solution determines the quintessence potential uniquely and it differs from solutions which have been used to study inflation previously. It relays on a unification of geometry and dark matter implemented through the definition of a functional relation between the scale factor of the (...) Universe and the quintessence field. For a positive curvature Universe, this solution produces perpetual accelerated expansion rate of the Universe, while the Hubble parameter increases abruptly, attains a maximum value and decreases thereafter. The behavior of this cosmological solution is discussed and its main features are displayed. The formalism is extended to include matter and radiation. (shrink)

Kant’s first antinomy in the Critique of Pure Reason deals with the question of the size of the world. The temporal portion of the problem, on which I will focus in this paper, concerns the question of whether the world has a beginning in time or whether it exists eternally. Kant is sometimes understood as arguing that since neither one of the conflicting options can be confirmed, one needs to reject the common mistake of both opponents, namely, that we know (...) the world as a thing in itself, and embrace instead Kant’s transcendental idealism. In view of modern cosmology, Kant’s resolution of the first antinomy may appear outdated. Modern cosmological theories, after all, do suggest that the world evolved from a singular point by a big bang or through a cycle of successive expanding and contracting phases. I wish to argue in this paper that Kant’s analysis of the first antinomy does not involve questions of confirmability and that its lessons apply to modern cosmology as well. Kant’s analysis challenges the view that the world as a whole is a proper object for human investigation, but it does not reject the legitimacy of the cosmological project of explaining the current state of the universe and its evolution in terms of earlier events in the history of the world. It merely shows that modern theories are misguided only insofar as they attempt to affirm that the singular point is the absolute beginning of the world or that the cycle of expansion and contraction is ultimately infinite. Thus, Kant does not deny science as a legitimate avenue of research. He rather keeps cosmology from sliding into the dogmatic paths of traditional cosmological speculations, which purported to account for the absolute origin of the world by means of theological and metaphysical considerations.

It has been known for long time that the cosmic sound wave was there since the early epoch of the Universe. Signatures of its existence are abound. However, such a sound wave model of cosmology is rarely developed fully into a complete framework. This paper can be considered as our second attempt towards such a complete description of the Universe based on soliton wave solution of cosmological KdV equation. Then we advance further this KdV equation by virtue of Cellular (...) Automaton method to solve the PDEs. We submit wholeheartedly Robert Kurucz’s hypothesis that Big Bang should be replaced with a finite cellular automaton universe with no expansion. Nonetheless, we are fully aware that our model is far from being complete, but it appears the proposed cellular automaton model of the Universe is very close in spirit to what Konrad Zuse envisaged long time ago. It is our hope that the new proposed method can be verified with observation data. But we admit that our model is still in its infancy, more researches are needed to fill all the missing details.

The main foundations of the standard \CDM model of cosmology are that: the redshifts of the galaxies are due to the expansion of the Universe plus peculiar motions; the cosmic microwave background radiation and its anisotropies derive from the high energy primordial Universe when matter and radiation became decoupled; the abundance pattern of the light elements is explained in terms of primordial nucleosynthesis; and the formation and evolution of galaxies can be explained only in terms of gravitation within a (...) inflation + dark matter + dark energy scenario. Numerous tests have been carried out on these ideas and, although the standard model works pretty well in fitting many observations, there are also many data that present apparent caveats to be understood with it. In this paper, I offer a review of these tests and problems, as well as some examples of alternative models. (shrink)

This paper deals with two important English scientists of the first half of the twentieth century: Edward Arthur Milne and James Hopwood Jeans. It examines the philosophical reasons that, in 1932, induced Milne to devote himself to the newborn modern cosmology. Among those reasons, it is argued that the most important ones were some of Jeans’ philosophical statements regarding the new relativistic view of the expanding universe. In particular, Milne reacted to some confusing idealist opinions expressed by Jeans in the (...) London newspaper The Times, in May 1932, in a debate on the expansion of the universe. Actually, as it will be shown, Jeans received many criticisms about the philosophical reasonings present in all of his popularizing works. (shrink)

The bulk of this work is a responsible and well documented exposition of Whitehead's major themes with emphasis on how they contribute to his theory of perception and how his developing theory of perception contributes to them. Although Schmidt divides Whitehead's development into three parts, the important part of the project, and obviously his favorite, is the elucidation of Whitehead's "mature theory of perception" and the demonstration that it provides a foundation for the cosmological system and his philosophy of (...) science. Throughout, Whitehead is presented as an empiricist, although not in the usual sense. Perception and immediate experience are his starting point, but "perception" is used in a more basic, generic sense than is customary. It includes conception as well as sense-presentation. Schmidt pays prolonged and welcome attention to presentational immediacy, causal efficacy, and symbolic reference. The book contains some useful expansions of underdeveloped Whiteheadian doctrines, elucidations of Whiteheadian obscurities, and a number of interpretive distinctions, all of which serve to make it a useful new commentary as well as a proposal of an important thesis.--S.

Modern cosmological theories, after all, do suggest that the world evolved from a singular point by a big bang or through a cycle of successive expanding and contracting phases. I wish to argue in this paper that Kant’s analysis of the first antinomy does not involve questions of confirmability and that its lessons apply to modern cosmology as well. Kant’s analysis challenges the view that the world as a whole is a proper object for human investigation, but it does not reject the legitimacy of the cosmological project of explaining the current state of the universe and its evolution in terms of earlier events in the history of the world. It merely shows that modern theories are misguided only insofar as they attempt to affirm that the singular point is the absolute beginning of the world or that the cycle of expansion and contraction is ultimately infinite. Thus, Kant does not deny science as a legitimate avenue of research. He rather keeps cosmology from sliding into the dogmatic paths of traditional cosmological speculations, which purported to account for the absolute origin of the world by means of theological and metaphysical considerations.

In lieu of an abstract, here is a brief excerpt of the content:Decolonial Movidas: María Lugones’s Notion of Decolonial Aesthesis through CosmologiesDenise Meda CalderonIntroductionMaría Lugones advances a decolonial feminist methodology that allows one to see both dehumanizing social reductions of colonized peoples and the resistant relations operating within non-dominant socialities. By exploring this double “seeing,” I articulate the relationship between resistant socialities and Lugones’s notion of decolonial aesthesis. In her only published text on decolonial aesthesis, Lugones states: “Thinking about aesthesis, (...) I think about the body and permeability and all that permeability allows us to reconceive about the world we live in” (qtd. in Ortega 275). Lugones promotes a notion of decolonial aesthesis that engages a resistant permeable sensing and, I argue, is exposed by her distinct approach to cosmology.1My analysis begins with Lugones’s decolonial methodology to articulate a “seeing” of coloniality that I contend leads to her development of decolonial aesthesis. In particular, I show that Lugones sketches a view of decolonial aesthesis as a sensing that grounds resistance to dehumanizing social reductions and reveals a non-dominant social relationality expressed through concrete sensuous movements. I suggest that Lugones theorizes a communal interconnected dimension of resistance as decolonial aesthesis through cosmologic relation. To flesh out this point, I turn to two interlocutors central to Lugones’s intellectual genealogy: Gloria Anzaldúa and Rodolfo Kusch. I conclude by interpreting Lugones’s reading of Anzaldúa as a coalitional movida performing decolonial aesthesis.Moving to “Seeing” ColonialityLugones’s 2010 essay “Toward a Decolonial Feminism” constitutes a methodological intervention or movida in gender scholarship. Referring to the [End Page 22] expansive global power system, Lugones argues that gender is historically implicated as part of the colonial/modern project and sustains a dominative closure that marks alternative socialities as unintelligible. The colonial/modern system established norms that did not previously inform social communities. A gender binary was imposed onto colonized peoples, erasing the existing socialities that informed the everyday of those peoples. Lugones’s analysis of gender exposes the deep social fissures that emerge from coloniality, and the tremendous harm sustained by reading gender across all social arrangements and onto all knowledge systems.According to Lugones, the colonial/modern category of gender shows a pervasive subjugation to non-humanity of peoples whose sex status does not conform to binary logics. Regarding these reductive processes, Lugones writes: “This dehumanization and bestialization occurred precisely because these people were not understood by the colonizers and enslavers as social agents, and thus their sexual difference [was] not socializable. Thus, one does not find gender; animals do not have gender” (“Gender and Universality” 44). Since gender is assigned to humans, reading gender onto colonized peoples covers up dehumanization, even in calls for gender-based liberation.It is precisely through seeing coloniality that we can track the concealed social arrangements and see the worlds of sense that do not conform to the colonial/modern system. Lugones suggests this point in the following quote:To see the coloniality is to see both jaqi, the persona, the being that is in a world of being without dichotomies, and the beast, both real, both vying under different powers for survival. Thus to see the coloniality is to reveal the very degradation that gives us two renditions of life and a being rendered by them.(“Toward a Decolonial Feminism” 751–52)As Lugones’s words indicate, seeing coloniality involves a complex sensing that goes beyond seeing from dominant social norms and gender roles.Lugones’s methodological movida of seeing coloniality reveals the dichotomous categorization as part of the immense violence committed against peoples as colonized subjects with non-human status. This move urges a recognition of the superimposed categories that continue to harm and separate colonized peoples from their fluid relations with cosmologies (Lugones, “Toward a Decolonial Feminism” 746). Seeing the coloniality of gender elicits a transition to the possibilities of sensing from the positionalities deemed animal, in search of socialities that are not mediated by modern/colonial categories. Subsequently, seeing coloniality is a pivotal methodological movida to theorizing resistance in non-dominative socialities, or what Lugones calls decolonial aesthesis.2 [End Page 23]Decolonial AesthesisLugones’s decolonial aesthesis is not concerned...

In order to resolve the cosmological constant problem, the notion of reference frame is re-examined at the quantum level. By using a quantum non-linear sigma model (Q-NLSM), a theory of quantum spacetime reference frame is proposed. The underlying mathematical structure is a new geometry endowed with intrinsic second central moment (variance) or even higher moments of its coordinates, which generalizes the classical Riemannian geometry based on only first moment (mean) of its coordinates. The second central moment of the coordinates (...) directly modifies the quadratic form distance which is the foundation of the Riemannian geometry. At semi-classical level, the second central moment introduces a flow which continuously deforms the Riemannian geometry driven by its classical Ricci curvature, which is known as the Ricci flow. A generalized equivalence principle of quantum version is also proposed to interpret the new geometry endowed with at least second moment. As a consequence, the spacetime is stabilized against quantum fluctuation, and the cosmological constant problem is resolved within the framework. With an isotropic positive curvature initial condition, the long flow time solution of the Ricci flow exists, the accelerating expansion universe at cosmic scale is an observable effect of the spacetime deformation of the normalized Ricci flow. A deceleration parameter − 0.67 consistent with measurement is obtained by using the reduced volume method introduced by Perelman. Effective theory of gravity within the framework is also discussed.

This article situates Edward Gresham'sAstrostereon, or A Discourse of the Falling of the Planet(1603), a little-known English astronomical treatise, in the context of the cosmo-theological debate on the reconciliation of heliocentrism with the Bible, triggered by the publication of Nicholas Copernicus'sDe revolutionibus orbium coelestiumin 1543. Covering the period from the appearance of the ‘First Account’ of Copernican views presented in Georg Joachim Rheticus'sNarratio Prima(1540) to the composition ofAstrostereonin 1603, this paper places Edward Gresham's commentary and exegesis against the background of (...) the views expressed by his countrymen and the thinkers associated with the Wittenberg University – such as Philipp Melanchthon, Caspar Peucer, and Christoph Rothmann. Comparing the ways in which they employed certain biblical passages – either in favour of or against the Earth's mobility – the paper emphasizes Gresham's ingenious reading of the Hebrew version of the problematic excerpts, and his expansion of the accommodation principle.

The formulation of the second law of thermodynamics in the frame of general relativity is reconsidered in the case of an istotropic homogeneous universe. We show that there appears then a direct link between the cosmological state of the universe, as expressed in terms of conformal coordinates, and quantities such as energy density, pressure, and entropy associated with the description of nature. In the early universe there appears a kind of phase transition due to transfer of gravitational energy to (...) matter associated with the cosmological expansion if the universe starts with a non-Euclidian (space) state. As a result, we may envisage the possibility of a “cold big-bang model,” in which the universe would start at zero temperature and entropy. The temperature goes then through a maximum before entering the present area of cooling related to adiabatic expansion. (shrink)

The cosmological relevance of emptiness—that is, space without bodies—is not yet sufficiently appreciated in natural philosophy. This paper addresses two aspects of cosmic emptiness from the perspective of natural philosophy: the distances to the stars in the closer cosmic environment and the expansion of space as a result of the accelerated expansion of the universe. Both aspects will be discussed from both a historical and a systematic perspective. Emptiness can be interpreted as “coming” in a two-fold sense: (...) whereas in the past, knowledge of emptiness, as it were, came to human beings, in the future, it is coming, insofar as its relevance in the cosmos will increase. The longer and more closely emptiness was studied since the beginning of modernity, the larger became the spaces over which it was found to extend. From a systematic perspective, I will show with regard to the closer cosmic environment that the Earth may be separated from the perhaps habitable planets of other stars by an emptiness that is inimical to life and cannot be traversed by humans. This assumption is a result of the discussion of the constraints and possibilities of interstellar space travel as defined by the known natural laws and technical means. With the accelerated expansion of the universe, the distances to other galaxies (outside of the so-called Local Group) are increasing. According to the current standard model of cosmology and assuming that the acceleration will remain constant, in the distant future, this expansion will lead first to a substantial change in the epistemic conditions of cosmological knowledge and finally to the completion of the cosmic emptiness and of its relevance, respectively. Imagining the postulated completely empty last state leads human thought to the very limits of what is conceivable. (shrink)

This essay explores the discoved place in human noosphere called as "Cosmos-not-Here," encompassing the speculative realms of science fiction, religious eschatology, and theoretical astrophysics. The content of "Cosmos-not-Here" contrasts with the same of "Cosmos-Here," representing humanity's tangible explorations and mastery of the physical universe. The text delves into how the Cosmos-not-Here operates as a mental construct, offering humanity an imaginative escape into utopian visions and hypertextual narratives, while disregarding the constraints of established physical laws. -/- The discussion emphasizes humanity's innate (...) psychological drive, metaphorically expressed as "forward and upward," linking it to a sacred yearning for cosmic harmony and expansion. This drive manifests culturally in phenomena like Russian aspirations, illustrated by the "Gagarin Smile," and the global fascination with cosmic-themed speculative fiction, games, and spiritual constructs such as astrology. -/- The essay concludes by identifying a universal "Cosmic-We" ethos, characterized by a shared attraction to the cosmos as a concept of transcendence and infinite potential, reflecting humanity's enduring pursuit of meaning beyond the utilitarian confines of terrestrial existence. The analysis reveals the philosophical resonance of this semantic cluster with ancient and medieval cosmologies, suggesting its timeless significance in human thought. (shrink)

Typical cosmological models are based on the postulate that space is homogeneous. Space however contains overdense regions in which matter is concentrating, leaving underdense regions of almost void. The evolution of the scale factor of the universe has been established from measurements on SNIa. Since such events occur in regions were matter is present, we may expect that most of the SNIa are located in overdense regions. This means that the evolution of the scale factor has been established in (...) a biased manner, by considering only information coming from overdense regions, excluding the one from the underdense regions. We develop a simple model to analyze the effect of this bias, and show that it leads to the appearance of a new tensor in the Einstein equation of general relativity, which can account for the apparent acceleration of the expansion of the universe. We further show that this tensor tends to be proportional to the FLRW metric tensor, and that the constant of proportionality quantitatively corresponds to the measured cosmological constant. We finally discuss the applicability of the bias to other probes used in determining the dynamics of the universe. (shrink)

An expansive, yet succinct, analysis of the Philosophy of Religion – from metaphysics through theology. Organized into two sections, the text first examines truths concerning what is possible and what is necessary.

One of the few authors to have explicitly connected the physical issue of the expansion of the universe with the philosophical topic of the metaphysical status of space is Gerald James Whitrow. This paper examines his view and tries to highlight its strong and weak points, thereby clarifying its obscure aspects. In general, this really interesting philosophical approach to one of the most important phenomena concerning our universe, and therefore modern cosmology, has been very rarely tackled. This unicity increases (...) the value, from a physical, philosophical and historical point of view, of Whitrow’s attempt and calls for new research. (shrink)

He is the animating principle of existence and in everything there isExu. The crossroads is its space-time and this fact would explain why “black culture is acrossroads culture”.

Of all the species that live on this planet, as far as we know, man is the only one capable of awareness; observing the sky, understanding its beauty, and asking questions about the meaning of life and that of death, on the beginning and the end, both about the Universe and man himself. The questions range in all directions: why is there something instead of nothing? Who is the architect of reality, and why does it appear to us as it (...) does, rather than in some other way? What's the point of all this? Where does life originate, and what are the origins of the Universe that encompasses it? This book aims to introduce and address the questions that are often asked and answer with the knowledge that science provides us. Where does all the matter we are made of come from and what constitutes the Universe? Is it true that there is matter and energy whose existence can be intuited only indirectly, as the existence of the wind is deduced from leaves' motion? Einstein was right in his revolutionary description of reality, on nature of space and time, inextricable units in their apparent dichotomy. Does each observer truly observe a 'different' time from another observer? Can we move back and forth in the time? How space and time are modified by astronomical objects such as black holes, and what is the nature of the latter? Will time and the Universe end and how did they originate? The Universe is incredibly vast, housing hundreds of billions of galaxies within the observable Universe alone. Beyond what we can observe, there may exist an unimaginably vast expanse that extends infinitely and beyond our imagination. Our Universe, enormous as it may be, is not the only one. That's all predicted by certain cosmological and physical theories. Is life unique to Earth, or does the Universe harbor other forms of life that remain undiscovered to us? Finally, we are confronted with the most intriguing and elusive question of all: was all of this deliberately planned by some higher power, or is it merely a result of natural processes? Each of these questions touch on a fundamental aspect of our perception of the Universe and our quest to comprehend humanity's place in the cosmos. (shrink)

Two different derivations of the observed vacuum energy density are presented. One is based on a class of proper and novel generalizations of the de Sitter solutions in terms of a family of radial functions R that provides an explicit formula for the cosmological constant along with a natural explanation of the ultraviolet/infrared entanglement required to solve this problem. A nonvanishing value of the vacuum energy density of the order of ${10^{- 123} M_{\rm Planck}^4}$ is derived in agreement with (...) the experimental observations. A correct lower estimate of the mass of the observable universe related to the Dirac–Eddington–Weyl’s large number N = 1080 is also obtained. The presence of the radial function R is instrumental to understand why the cosmological constant is not zero and why it is so tiny. Finally, we rigorously prove why the proper use of Weyl’s Geometry within the context of Friedman–Lemaitre–Robertson–Walker cosmological models can account for both the origins and the value of the observed vacuum energy density. The source of dark energy is just the dilaton-like Jordan–Brans–Dicke scalar field that is required to implement Weyl invariance of the most simple of all possible actions. The full theory involving the dynamics of Weyl’s gauge field Aμ is very rich and may explain also the anomalous Pioneer acceleration and the temporal variations of the fundamental constants resulting from the expansion of the Universe. This is consistent with Dirac’s old idea of the plausible variation of the physical constants but with the advantage that it is not necessary to invoke extra dimensions. (shrink)

A recently published hypothesis on the nature of time by physicist Richard A. Muller seeks to provide an objective account of the present moment and the ‘flow’ of time. Muller also claims that his hypothesis makes testable predictions. It is shown that the predictions offered cannot be used to test Muller’s hypothesis, that the hypothesis does not rate scientific status, has a number of questionable metaphysical premises, and is merely a re-fashioning of the Growing Block theory of time.

Around 3 decades ago, Jayant Narlikar & Halton Arp argued on possible variable mass hypothesis cosmology (VMH). In the meantime, the Earth expansion problem has attracted great interest, and recent study gives geodetic evidence that the Earth has been expanding, at least over the recent several decades. Therefore, in the present article discusses some interesting effects related to varying G, but here we argue that instead of varying G we can think of varying mass (M). Among other things we (...) discuss receding planets from the Sun, calculation of Pioneer spacecraft anomaly as proposed by B.G. Sidharth, and also possible slight change of LAGEOS Satellite. Further observation to verify or refute this conjecture is recommended, especially based on geological evidence of expanding earth. (shrink)

In this expansive and highly original two-volume work, Jim Behuniak reformulates John Dewey's late-period "Cultural turn" and proposes that its next logical step is an "intra-Cultural philosophy" that goes beyond what is commonly known as "comparative philosophy." Each volume models itself on this new approach, arguing that early Chinese thought is poised to join forces with Dewey in meeting an urgent cultural need: namely, helping the Western tradition to correct its outdated Greek-medieval assumptions, especially where these result in pre-Darwinian inferences (...) about the world. Relying on the latest findings in Chinese philosophy, these volumes establish "specific philosophical relationships" between Dewey's ideas and early Chinese thought for this purpose, showing how together they can assist us in getting our thinking "back in gear" with the world as it is currently known through the biological, physical, and cognitive sciences. Volume One: Dao and Nature engages Dewey with themes generally associated with "Daoism," and includes discussion of the organization of organic form, teleology, cosmology, knowledge, the body, and technology. Volume One thus works to establish "Chinese natural philosophy" as an empirical framework in which to consider the cultural-level phenomena examined in Volume Two: Dao and Culture. (shrink)

This article starts by noting the general lack of acknowledgment of alternative traditions in the dominant western sustainability discourse in education. After critically analyzing the western human–nature relationship in the context of Enlightenment, modernity and colonial expansion, this article introduces two non-western ecological discourses from Eurasia and Asia, Noöspherism and Neo-Confucianism, which offer clear contrasts to the western sustainability framework. Using theoretical argumentations, the article goes on to examine the cosmological and ontological categories expounded by Vladimir Vernadsky of (...) Russia and Yulgok Yi of Korea, whose philosophical foundations with unique foci on the anthropocosmic and cosmoanthropic types of human–nature relationships could well be alternatives and/or additions to the dominant western discourse. The article concludes with a twofold comparison: between Eurasian and Confucian heritages, and these two with the mainstream western ecological discourse. (shrink)
