The last century is filled with victories and failures, passions, and interests. World wars and revolutions, the change of political regimes, ideologies, and ideological orientations — all this provoked a formation of social and political chaos, which sometimes had to be overcome in a totalitarian way through sole commanding and by one-party dictatorship. At the same time, one can observe the successes of cognition, culture, scientific and technological development, which, however, can hardly be called “progress”. Because the mass destruction weapons of certain “partners” in globalism have also been increased. Ready for self-destruction, “man in time” did not become yet the master of his destiny in the last century, but in many ways remained a mystery to himself. Despite the fact that over the past century man has learned a lot about his own psychology, consciousness and subconscious, he still needs further self-knowledge no less than in those times when the Oracle of Delphi called for it. Today, as ancient times, one needs to know better what motivates his sometimes rational, and sometimes, mildly speaking, very strange behavior. Who is man in time? To understand this, one must go beyond the limits of itself being to other times and spaces. Even to times and spaces of a cosmic scale, to the spaces and to the depths of our Universe, where a man was born and will disappear, perhaps preserved in its cosmic memory. The memory of the Universe is symbolized by world constants that arose as a result of the Big Bang and the birth of the Universe from a singularity point. Memory of man inherits this property of the Cosmos. The memory is a system-forming factor that creates man and its world. This is what rigorous science can offer to explain the cosmic origin of man and his memory. Artistic imagery can continue the efforts of science. Culture, literature, first of all, can create imageries that will tell about man and his time more than abstract theory. The imageries will tell that man has not yet lost his freedom of creativity. He must remember the past, live in the present, look and go to the future.

AbstractCosmological discoveries over the past century have completely changed our picture of our place in the universe. New observations have a realistic chance of probing nature on heretofore unimaginable scales, and as a result are changing the nature of fundamental science. Perhaps no other domain of science has an equal capacity to completely change our perspective of the world in which we live.

Thirty years ago, observational cosmology consisted of the search for two numbers: Ho, the rate of expansion of the universe at the position of the Galaxy; and qo, the deceleration parameter. Twenty years ago, the discovery of the relic radiation from the Big Bang produced another number, 3oK. But it is the past decade which has seen the enormous development in both observational and theoretical cosmology. The universe is known to be immeasurably richer and more varied than we had thought. There is growing acceptance of a universe in which most of the matter is not luminous. Nature has played a trick on astronomers, for we thought we were studying the universe. We now know that we were studying only the small fraction of it that is luminous. I suspect that this talk this evening is the first IAU Discourse devoted to something that astronomers cannot see at any wavelength: Dark Matter in the Universe.

This article considers the key-ideas for modern scientific understanding of the origin and evolution of the Universe. George Gamow is one of the first scientists to create the theory of the Big Bang the theory of great explosion. Gamow is a famous physicist who came from the city of Odessa (Ukraine) andgot interested in the origin of chemical elements. He suggested that in the past of the Universe before it had been created by the «Big Bang» (the theory of great explosion), the Universe had had much more substantial density and higher temperature than now. He was the first person to focus on unique properties of the Universe and to suggest existence of cosmic microwave background (CMB). The following disclosure of the CMB started the era of modern cosmology.


It is hard to believe today that most scientists in the year 1920 believed that our Galaxy was all there is to the whole Universe—the ‘island Universe’ as it was then called. The difference between our present day view, with all its subtle complexities, and such a primitive notion has been brought about very largely by the accumulation of observational data. Almost immediately following the year 1920 Hubble disposed of the ‘island Universe’ concept and for the past fifty years astronomers have worked on the basis that our Galaxy is but one among thousands of millions strewn more or less uniformly throughout space. Although observation plays the key role in determining which ideas survive and which are rejected, ideas themselves frequently come from theoretical studies. Already in 1922 Friedmann discovered the theoretical models of the Universe which are now often described as the ‘big bang’ cosmologies. In this lecture I shall not be much concerned with these models, for the personal reason that I happen to be not very interested in them. But it is of relevance that I should explain to you why this is so.

This is the story of a single pebble. It is just a normal pebble, as you might pick up on holiday - on a beach in Wales, say. Its history, though, carries us into abyssal depths of time, and across the farthest reaches of space. This is a narrative of the Earth's long and dramatic history, as gleaned from a single pebble. It begins as the pebble-particles form amid unimaginable violence in distal realms of the Universe, in the Big Bang and in supernova explosions and continues amid the construction of the Solar System. Jan Zalasiewicz shows the almost incredible complexity present in such a small and apparently mundane object. Many events in the Earth's ancient past can be deciphered from a pebble: volcanic eruptions; the lives and deaths of extinct animals and plants; the alien nature of long-vanished oceans; and transformations deep underground, including the creations of fool's gold and of oil. Zalasiewicz demonstrates how geologists reach deep into the Earth's past by forensic analysis of even the tiniest amounts of mineral matter. Many stories are crammed into each and every pebble around us. It may be small, and ordinary, this pebble - but it is also an eloquent part of our Earth's extraordinary, never-ending story.

In this review article, the study of the development of relativistic cosmology and the introduction of inflation in it as an exponentially expanding early phase of the universe is carried out. We study the properties of the standard cosmological model developed in the framework of relativistic cosmology and the geometric structure of spacetime connected coherently with it. The geometric properties of space and spacetime ingrained into the standard model of cosmology are investigated in addition. The big bang model of the beginning of the universe is based on the standard model which succumbed to failure in explaining the flatness and the large-scale homogeneity of the universe as demonstrated by observational evidence. These cosmological problems were resolved by introducing a brief acceleratedly expanding phase in the very early universe known as inflation. The cosmic inflation by setting the initial conditions of the standard big bang model resolves these problems of the theory. We discuss how the inflationary paradigm solves these problems by proposing the fast expansion period in the early universe. Further inflation and dark energy in fR modified gravity are also reviewed.

Nonlinear oscillations in the dynamic system of gravitational and material fields are considered. The problems of singularities and caustics in gravity, expansion and baryon asymmetry of the Universe, wave prohibition of collapse into black holes, and failure of the Big Bang concept are discussed. It is assumed that the effects of the expansion of the Universe are coupling with the reverse collapse of dark matter. This hypothesis is used to substantiate the vortex and fractal structures in the distribution of matter. A system of equations is proposed for describing turbulent and fluctuation processes in gravitational and material fields. Estimates of the di usion parameters of such a system are made in comparison with the gravitational constant.

John Taylor complains that the Kalam cosmological argument gives the appearance of being a swift and simple demonstration of the existence of a Creator of the universe, whereas in fact a convincing argument involving the premiss that the universe began to exist is very difficult to achieve. But Taylor's proffered defeaters of the premisses of the philosophical arguments for the beginning of the universe are themselves typically undercut due to Taylor's inadvertence to alternatives open to the defender of the Kalam arguments. With respect to empirical confirmation of the universe's beginning Taylor is forced into an anti-realist position on the Big Bang theory, but without sufficient warrant for singling out the theory as non-realistic. Therefore, despite the virtue of simplicity of form, the Kalam cosmological argument has not been defeated by Taylor's all too swift refutation.

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.
