When we say universe, we think of it as everything there is because of the Big Bang, around 13.8 billion years ago. However, the Big Bang that created our universe may not have been a onetime event. Instead, it could have happened again, and again, and again, an infinite number of times. And just as our Big Bang created our universe, each of those events would have created other universes, a process that would increase its rate exponentially in time. From this perspective, there are no reasons to believe that our universe was the 1st. For that purpose, the concept of multiverse was born. Mathematical computations show that the multiverse would contain an infinite number of universes, sometimes called ¿pocket¿ or ¿bubble¿ universes. Most of these ¿pocket¿ universes would be very boring, without structure or complexity and lifeless, while some might even resemble our own. By definition, an infinite number of possibilities means that everything that can happen, will happen in one universe or another. So is there another Earth, nurturing intelligent life?One of the theories which are strong evidence for Multiverse existence is ¿Comic Microwave Background (CMB)¿ explain in my Monograph.

The book titled ¿Genesis of Principles of Vedic Astrology¿ has proved that the entire subject is a derivative of several disciplines of science more essentially astronomy and physics. Thus, the contention of the think tank that astrology is not fit enough to be considered as a discipline in the academic pursuits of any university as it does not base its principles on any science subjects including statistics is utterly defeated. Ongoing through the book the readers will realize with a great admiration the uncanny ability and wisdom of the ancients in designing the subject of astrology. The principles clearly exhibit the application of modern science such as the 'Einstein's Theory of Deflection of Light' and mathematical maxim. Every principle is described about its genesis completely based on modern sciences with finest drawings which are self-explanatory. The author feels that the book brings in a change in the mental outlook of the skeptics about the subject, particularly the modern educated unbelievers. This ushers in the renaissance of astrology in the very land of its glory and bring credit both to the astrologer and the subject of astrology.

Our study focuses on eclipsing Algol binary systems. We have performed photometric studies and analyses for three eclipsing Algol binary stars. Orbital and physical parameters of the recently discovered Algol type eclipsing binary systems GSC 04328-02164 and GSC 03164-01558 are determined. The spectral types of the primary and secondary components are F2 and G0 for the first system and G2 and K2 for the second system, the stars of the two systems are main sequence stars. The results have already been published in The Astronomical Journal, 151:19, 2016. Light curve models of QS Vir Algol system are constructed according to photometric observation using Kottamia telescope. Orbital and physical parameters are determined. The primary white dwarf is more massive and hotter than the secondary red dwarf component. O¿C curve studies indicate that the change in the orbital period P¿ =1.108*10^-8 d yr^-1 and the mass-loss rate M¿ = 2.348*10^-8 M¿ y^-1

Humanity faces three main challenges. To "save the planet", as pursued by the 17 goals of UN 2030 agenda: tackling climate change, etc... The second, space exploration, will maybe take us to Mars. The third challenge is to save civilization. This third challenge is disattended and neglected, but eight billion terrestrials cannot save their civilization if they will not begin immediately to expand into space. Expanding into space is different from just exploring space. Exploration can be done by trained astronauts, able to bear 4-5G acceleration and hard and dangerous re-enter in atmosphere, during short missions. To travel, work and live in space we have to safeguard our life and health: protection from cosmic radiation, artificial gravity, low accelleration, safe reenter, etc. A full change of paradigm. I¿d like to see not only the space tourism branch facing this problem. I¿d like to see many other industrial, commercial and governmental branches to tackle this challenge: saving civilization from a possible implosion, due to the many problems we have on this, now, small planet.

The present monograph is dedicated to description of Georgian astronomical manuscript ¿Star Book¿ of XVIII century. The geocentric Universe, the Sun, the Moon and planets, constellations and stars, rare astronomical phenomena, instruments, tables and maps were described in this astronomical manuscript. This little studied astronomical manuscript contains information of different scientific directions, unknown names, facts, and data. We considered in the present monograph the scientific significance of the astronomical manuscript ¿Star Book¿, including the scientific views and theories of the manuscript's author. We proposed our understanding, explanations, and ideas. This monograph will be useful for researchers in the fields of astronomy, the history of astronomy, interrelations of Eastern and Western cultures, also lecturers, PhD students and readers with general scientific interests.

The Sun is a subject of interest since childhood for any person living on the Earth. The Sun is the only source of life. Hence it is studied deeply in many aspects. This book is a kind gesture for the people who are willing to have preliminary knowledge of the Sun. It is also a basic book for new Ph.D. students and Master and bachelor degree students. The easy language of this book is the main tool. The information of the Sun is studied everywhere but it is in bit difficult language. Here it is a gesture to understand the Sun in very simple and understanding language.

Planetary theory discusses the variation of the orbital elements of the solar system planets, through the theory of perturbation. Many theories were introduced to study this variation. The most powerful Hamiltonian mechanics procedures are adopted and explained clearly in this book. This book is recommended and directed to graduate students and researchers in dynamical astronomy and applied mathematics. The style is comprehensive and authoritative. We deal, with the construction of semi analytic Hamiltonian J ¿ S planetary theory in terms of Poincaré canonical variables. The methods of work could be extended to be implemented, for the case of n planets (point masses), yielding more precise algebraic and numerical results, using the Jacobi ¿ Radau system of origins, assuming any order in planetary masses. The terms of the Poisson series are truncated at power 6 at most in the eccentricity ¿ inclination. The book includes the Macsyma programs used to obtain the expansion of the disturbing function up to order 6, in eccentricity ¿ inclination, which is the upper limit of power for a personal computer. The expansion of ¿-n took the space of 3400 pages in the site of internet.

The Universe still conceals many enigmas and mysteries. The discovery of the Pre-Big Bang in the first cosmological model from antiquity, the biblical scheme of creation, adds many more. In this book, we have explored some of these phenomena, offering our explanations of the mysteries that stretch from the pre-Big Bang to the present day. It only remains for the astrophysicists to look underneath and to bring their contributions. Having scientifically restored the biblical scheme of creation in the books of the collection "Astronomy & Theology", it has given birth to a new cosmological model called "The Universal Cosmological Model" and to a new science known as "Astrotheology". This science will now allow theologians to understand the Universe and to take part in the debates with their heads held high by the study of the Universal Cosmological Model in theological faculties. From now on, "the Universal Cosmological Model" seals the link between science and religion.

This is a book of the history & the evolution of the universe.In this book we describe about the different models of the universe in different cases.we tried to find out the future case of the universe that what will be the condition in next.Black body radiation & Cosmic microwave background radiation is the new invention on the space that detect in our earth.We re-arrange some new calculations that will help us to describe the evolution & about Big-Bang.

All Indian Panch¿ngas (almanacs) of whatever variety are a total deviation of the observed sky. The difference as of now in the Makara Samkr¿nti (Uttar¿yana ¿ Winter Solstice) of January 14 to the actual of December 22 may not be significant but about 9000 years later, Winter Solstice will be found occurring on June 22. How absurd it would be is anybody¿s imagination. Hence a new Panch¿nga based on the Moving Zodiac as has been ordained by Var¿hamihira, Indian Astrologer and Astronomer par excellence, is the need of the hour. Temple or Domestic rituals are essentially governed by two important components, namely, ritual procedure and the muhurta time for the ritual, and the latter is most important of the two. When the muhurta time goes astray, the results go astray. When the results go astray, the world order gets disrupted. The almanac used for the purpose should be free of any errors. This book ¿ Infallible Indian Almanac¿ is an exposition of designing an error free Almanac, on the basis of total solar eclipse, in the very land of its glory.

Denne bog er en videreudvikling af en tidligere udgave. Den omhandler de af forfatteren definerede fire grundelementer: rum, tid, temperatur og relativitet, og som bidrager til at forklare en række fysiske begreber som universets form, radioaktivitet og tyngdekraft.
