A locally rotationally symmetric Bianchi-I model filled with strange quark matter (SQM) is explored in f(R, Lm) gravity as a non-linear functional of the form f(R, Lm)=R/2 +Lαm, where α is the free model parameter. We considered the special law of variation of Hubble’s parameter proposed by Berman (1983) and also used the power law relation between the scale factors to obtain the exact solution of the field equation, which matches the model of the universe. We also analyze the physical and geometrical aspects of the universe’s kinematic and dynamic behavior. Additionally, we employ equation-of-state (EoS) parameters and statefinder parameters as analytical tools to gain insights into the evolution of the universe. We use the ΛCDM model as a benchmark to validate the results. By placing the deviations of the universe from ΛCDM model and yet making important contributions to the study of the anisotropic nature of f(R, Lm) gravity within the framework of cosmological dynamics, the paper increases our comprehension of our cosmic evolution.

The theory of relativity is often regarded as inhospitable to the idea that there is an objective passage of time in the world. In light of this, many philosophers and physicists embrace a "block universe" view, according to which change and temporal passage are merely a subjective appearance or illusion. My aim in this paper is to argue against such a view, and show that we can make sense of an objective passage of time in the setting of relativity theory by abandoning the assumption that the now must be global, and re-conceiving temporal passage as a purely local phenomenon. Various versions of local becoming have been proposed in the literature. Here I focus on the causal diamond theory proposed by Steven F. Savitt and Richard Arthur, which models the now in terms of a local structure called a causal diamond. After defending the reality of temporal passage and exploring its compatibility with relativity theory, I show how the causal diamond approach can be used to counter the argument for the ideality of time due to Kurt Gödel, based on his "rotating universe" solution to the Einstein field equations (the Gödel universe). I defend the second component of his argument, the modal step, against the consensus view that finds it wanting, and reject the first step, showing that the Gödel universe is compatible with an objective passage of time as long as the latter is construed locally, along the lines of the causal diamond approach.

Though he may have been wary of -ism labels, in this paper I would like to assess to what extent Lawrence qualifies as an ecocritic and how his activity as a literary critic affected his own writing. Indeed, his critical output reveals that his primary concern was the quality of pulsing life immanent in a work, what he called the moral vision in a novel, rather than aesthetics. I will focus, though not exclusively, on Studies in Classic American Literature which he revised between 1919 and 1922 while writing the novel Kangaroo and the poem “The Humming-bird” included in Birds, Beast and Flowers. Echoing his assessment of Americans’ connections with their environment as depicted in classical works, Lawrence remarked about Australia in a letter to Baroness Anna von Richthofen “but the land has a ‘fourth dimension,’ and the white people swim like shadows over the surface of it” (Letters IV 238). In the novel Kangaroo, an epiphany in the Australian bush enables Lawrence’s alter-ego, Somers, to discard his ethnocentric views, the so-called “Babel” inherited from the country’s colonial past. By studying Lawrence’s keen observations of birds in particular, I hope to show how ecological awareness brings about a shift in language so that the “Babel” may be transcended in order to achieve “something beyond,” i.e., a cosmic ideal.

Herman Dooyeweerd (1953 , 28) writes that "the idea of cosmic time constitutes the basis of the philosophical theory of reality in [ A New Critique of Theoretical Thought ]." My aim is to present and defend the hypothesis that Dooyeweerd's idea of time is, in part, mistaken at its foundation. His idea of a cosmic temporal coherence of diverse modal aspects arose from the absolutization of a concept of temporal universality that he adopted uncritically as the transcendental basic Idea of cosmic time. My immanent-critical assessment leads to the hypothesis that temporality should be recognized as the first modal aspect, which, for Dooyeweerd, has been lost to view. Recovering both the sphere sovereignty of the temporal aspect and the equal universality of all aspects opens the way to a resolution of Dooyeweerd's temporal/supratemporal dialectic and to a new perspective on naive experience and the meaning of humans as God's image.

In this paper, we attempt to study spatially homogeneous Bianchi types-III, V, VI$_0$ $\&$ VI$_h$ cosmological models in $f(R, T)$ theory of gravity. Here the models are obtained by assuming forms of the function $f(R, T)$ as $f(R, T)= R + 2f(T)$ and $f(R, T) = f_1(R)+f_2(T)$. The exact solutions of Einstein's field equations (EFEs) have been obtained for two different types of physically viable cosmologies using a special form of Hubble parameter (HP). The physical and geometrical properties of these models have been discussed and expressions for the Ricci scalar $R$ in each case are obtained.

We explore the issue of cyclicity of cosmic time and how it might be a recorder of all events by its identification with the cosmic mind. We differentiate absolute time, universal (cosmic) time and the relative time as three distinct categories in the objective domain of temporal reckoning. Taking the idea of time generated by fundamental quantum events through natural frequencies of microsystems, we analyze the issue of generation of the cyclic time of the cosmos itself due to events undergone by all its oscillating contents. We propose that such macrocosmic processes of generation of cosmic times by the frequency of repetitive cosmic events necessarily requires the intermediary of psychic fields which being metaphysical and transcending matter, encode all information in a detailed manner in a memory that transcends space and generates repetitive events with subjects which lead to emergence of cosmic objective time. As a result, spatial as well as temporal non-locality becomes a reality, while individual free will becomes an appearance only. The difficulty in comprehending these novel ideas and conceptions only proves that our perceptions are deeply conditioned by our everyday experiences with space and time. The duration, symptomatics, fatality and cyclicity of COVID-like pandemics can be understood on this basis to have a deeper significance transcending virology and epidemiology.

This paper deals with those time travels mostly considered by physics, namely those in the form of the so-called closed timelike curves. Some authoritative scholars have raised doubts about the status of these journeys as proper time travels. By using David Lewis' famous definition of time travels proposed in 1976, we show that this proper status may actually be recovered, at least in some cosmological contexts containing spacetime regions, such as those concerning black holes described by the Kerr–Newman metric, that allow the formation of local closed curves. But, the mathematical incompatibility between ordinary black hole solutions to Einstein field equations and the cosmological solutions induces us to take into consideration the more general issue pertaining to the slippery interplay between models related to local and global aspects of the world, highlighting, in particular, the different notions of time that these domains inevitably imply. This leads us to think that time is not a univocal entity of the world, but is a scale-related characteristic which claims the adoption, when investigating its ontological status, of a sort of regional approach. We also briefly dwell upon the most appropriate form of realism that such a kind of dispute between local and global models may involve. [ABSTRACT FROM AUTHOR]

It is exceedingly frequent for people to speak of the ‘passing of time’. We do not, on the other hand, speak of the ‘passing of space’. There do not seem to be any common locutions concerning spatial passage analogous to those of time’s assumed passage. Further, there is a long held belief in the philosophy of time that there is no spatial analogue of the passage of time. This opinion does not take into account circumstances that cannot be noticed in day-to-day existence and which indicate that there is such a spatial analogue

In this paper, we attempt to study spatially homogeneous Bianchi type-I cosmological models in f(R) theory of gravity. The exact solutions of the Einstein's field equations (EFEs) have been obtained by assuming that the expansion (f) is proportional to the shear α and by using a special form of Hubble parameter (HP). Here we find two exact solutions by using the variation law of H based on two different values of n. The physical and geometrical properties of these models have been discussed and the function f(R) of the Ricci scalar R is obtained for each case. [ABSTRACT FROM AUTHOR]

The aim of this article is to formulate the theological notions of the end and fulfilment of the universe before the background of relativity theory and cosmology, in particular the lack of a global passage of time. It argues that the "arrow" of time is a local phenomenon, linked essentially to recording objects. On this basis, it makes the case that the notions of a common end of all local times and of a final, timeless state of the universe are viable independently of a global direction of time.

The General Theory of Relativity (GR) and the Dynamic Universe (DU) are evaluated in how they explain frequencies of atomic clocks. DU and GR predict the frequencies with equal accuracy, but their explanations, the postulates they apply in the explanations and the word-views that come along with them are entirely different. The central argument is that if unified and understandable physics is appreciated, then DU deserves to be taken as a viable alternative to GR. In GR different frequencies of identical atomic clocks are explained by letting rates of the flow of time in their frames of reference vary as functions of the clocks' states of motion and gravitation. The GRbased world-view is nonunderstandable because GR violates absolute simultaneity, and disunified because quantum mechanics is built on different postulates than GR. In DU different frequencies of identical atomic clocks are explained by letting their frequencies vary as functions of their states of motion and gravitation. As DU commits to absolute simultaneity and as the postulates of DU suffice as the ontological ground of quantum mechanics at least partially, DU provides an understandable and unified scientific world-view.
