This article argues the following five claims: 1. Plato’s description of the origins of cosmos in the Timaeus is not a myth, nor something unlikely: when he called it an eikos mythos or eikos logos, he meant a likely or trustworthy account on this very subject. 2. Among the details in this account, the following are prominent and surprising: a) the world was fashioned in time, in that precise point that was the beginning of time; b) several kinds of duration can be distinguished in cosmology (mainly eternity, sempiternity, perpetuity and time); and c) space is an entity characterized by movement and tension. 3. In the Statesman, Plato repeats much the same thing, adding this time the strange notion that the universe’s circular movement is periodically reversed. 4. In spite of the important differences in detail, there is a striking similarity between Plato’s account of the origins of the world and the explanation adopted by much of modern cosmology. 5. What Plato shares with so many instances of recent thought is here termed “cosmological imaginativity”. A first section of the paper deals exclusively with the Timaeus. Claims 1 and 2a are supported by a revision of the meanings of mythos and logos, followed by brief reference and discussion of the argument at Timaeus 27d, leading to the conclusion that Plato affirms that the ever-changing world has indeed had a beginning in time. Claim 2b describes five different types of duration, corresponding to Forms, the Demiurge, Space, the [empirical] world and its contents, physical objects. The second section is concerned with the myth in the Statesman, discussing it as a parallel and describing its peculiar turn to the Timaeus’ cosmology and cosmogony, a complex spheric and dynamic model. After digressing into some important ideas in modern cosmology, touching especially on affinities of some of Einstein’s ideas with of Plato’s own, the paper closes with a discussion of cosmological imaginativity, oriented to recover and recognize fully Plato’s greatness as a cosmologist.

ABSTRACT The discrepancy between estimates of the Hubble constant (H0) measured from local (z ≲  0.1) scales and from scales of the sound horizon is a crucial problem in modern cosmology. Peculiar velocities (vpec) of standard candle distance indicators can systematically affect local H0 measurements. We here use 2MRS galaxies to measure the local galaxy density field, finding a notable z  <  0.05 underdensity in the SGC-6dFGS region of 27  ±  2 per cent. However, no strong evidence for a ‘Local Void’ pertaining to the full 2MRS sky coverage is found. Galaxy densities are used to measure a density parameter, Δϕ+−, which we introduce as a proxy for vpec that quantifies density gradients along a supernova (SN) line of sight. Δϕ+− is found to correlate with local H0 estimates from 88 Pantheon Type Ia supernovae (SNe Ia; 0.02  <  z  <  0.05). Density structures on scales of ∼50 Mpc are found to correlate strongest with H0 estimates in both the observational data and in mock data from the MDPL2-Galacticus simulation. Using trends of H0 with Δϕ+−, we can correct for the effects of density structure on local H0 estimates, even in the presence of biased vpec. However, the difference in the inferred H0 estimate with and without the peculiar velocity correction is limited to < 0.1  per cent. We conclude that accounting for environmentally induced peculiar velocities of SN Ia host galaxies does not resolve the tension between local and CMB-derived H0 estimates.

Origin Of The Universe

The standard model of modern cosmology is known as the hot big bang, a name that refers to the initial state of the universe some fourteen billion years ago. The name Big Bang introduced by Fred Hoyle in 1949 is one of the most successful scientific neologisms ever. How did the name originate and how was it received by physicists and astronomers in the period leading up to the hot big bang consensus model in the late 1960s? How did it reflect the meanings of the origin of the universe, a concept that predates the name by nearly two decades? Contrary to what is often assumed, the name was not an instant success—it took more than twenty years before Big Bang became a household word in the scientific community. When it happened, it was used with different connotations, as is still the case. Moreover, it was used earlier and more frequently in popular than in scientific contexts, and not always relating to cosmology. It turns out that Hoyle’s celebrated name has a richer and more surprising history than commonly assumed and also that the literature on modern cosmology and its history includes many common mistakes and errors. An etymological approach centering on the name Big Bang provides supplementary insight to the historical understanding of the emergence of modern cosmology.

Living Being

A ternary ontological model in which the living being is a triad of I – form – substrate is described. I is an intangible subject, contemplating the content of consciousness and controlling the material body, which is the unity of the form and the substrate. The contents of consciousness are connected both with the form of the body, which I contemplate in the inner “mental space” in the form of in­formation, and with the substrate, which embodies the forms of the body and is responsible for sensations and intentions. The problem of control of the material body by the non-material self is solved under the assumption that the human brain is a quantum object. The ternary model of a living being is inscribed in an absolute ontology, in which the Absolute also has a threefold structure and is the unstitched unity of the absolute I, the absolute Form and the absolute Sub­strate. The Absolute creates the other world with its threefold energies, which provides the threefold structure of a living being. The created world arises from the timeless world of the potential possibilities of the Universe, which modern cosmology associates with its wave function. Created entities arise in the process of alienation from the Absolute, resulting in free will.

The spectacular advances of modern astronomy have opened our horizon on an unexpected cosmos: a dark, mysterious Universe, populated by enigmatic entities we know very little about, like black holes, or nothing at all, like dark matter and dark energy. In this book, I discuss how the rise of a new discipline dubbed multimessenger astronomy is bringing about a revolution in our understanding of the cosmos, by combining the traditional approach based on the observation of light from celestial objects, with a new one based on other ‘messengers’—such as gravitational waves, neutrinos, and cosmic rays—that carry information from otherwise inaccessible corners of the Universe. Much has been written about the extraordinary potential of this new discipline, since the 2017 Nobel Prize in physics was awarded for the direct detection of gravitational waves. But here I will take a different angle and explore how gravitational waves and other messengers might help us break the stalemate that has been plaguing fundamental physics for four decades, and to consolidate the foundations of modern cosmology.

Since the creation of GR and subsequent works in cosmology, the question of the curvature of space in the Universe is considered one of the most important and debated to this day. This is evident, because the curvature of space depends whether the Universe expands, contracts or is static. These discussions allowed the author to propose a paradoxical idea: simultaneous existence in the Universe of three interconnected space-times (positive, negative and zero curvature) and on this basis, to develop a theory in which each space-time plays its own role and develops in a strict accordance with its sign of curvature. The three space-time model of the structure of the Universe, proposed by the author, allows to solve many fundamental problems of modern cosmology and theoretical physics and creates the basis for building a unified physical theory (including one that unites GR and quantum physics).

Development of the concept of fractal cosmos after Anaxagoras has been followed up to the present. It is shown how the concept reappeared in the early Renaissance as a vague idea and subsequently took up a concrete formulation at the beginning of the 20-eth century. The modern cosmology state of affairs has been considered in view of the fractal paradigm and the current disputes and controversies discussed. It is argued that the concept of the hierarchical cosmos is still alive and might become an essential ingredient within the modern view of the universe.

Concise Definition

The paper offers a definition of cosmology and its connections with mythology, and presents contemporary theories as a secular mythical narrative suitable for anthropological analysis. The paper is dedicated to emphasizing the folklore characteristics of modern cosmology and points to the importance of popular cosmological narratives as reading that contains culturally, philosophically and even religiously relevant elements. Special attention is paid to cosmogonic myths that describe the state of the universe before the creation of space and time. A parallel has been drawn between modern cosmology and conventional cosmogonic myths. In the end, the paper offers a concise definition of popular cosmology and recalls the most important authors and popularizers of modern theories. The main task of the paper is to present the basic concepts that can contribute to a complete understanding of the anthropological character of the presentation of contemporary cosmology that we encounter in popular narratives. The aim of such an analysis is to observe the depth of the significance of modern science for creating a philosophical picture of the world that inherits secular worldviews. By treating popular cosmology as a modern myth, the paper presents a new dimension of the significance of scientific theories for today's civilization. Such an approach unravels the strictly positivist halo of cosmology and points to its anthropological character. The concepts highlighted in the paper serve as an illustration of the significance that the image of the universe and the position of the Earth has for the history of civilization. By presenting the cultural dimension of cosmology, it opens a space for dialogue between different branches of scientific research, i.e. it contributes to the communication of philosophy and science. Equally important, by illuminating the folklore character of the narrative of the origin and history of the universe, a training ground is created for philosophers and theologians who, in their own ways, interpret the creation of everything around us. By drawing attention to authors such as Neil deGrasse Tyson, Lawrence Kraus, Stephen Hawking, Michio Kaku and others, as contemporary bards and narrators, the paper seeks to contribute to the understanding of popular cosmology as an expression of modern man's need for great stories, for narratives that transcend the spatial and temporal frames of one generation, and that is exactly what myths do.
