This book was released on 2006-12-04 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: The latest observation of hundreds of exoplanets and the discovery of supermassive black hole at the center of many galaxies set the foundation for the theory presented in this book. The theory suggest that the sun and stars energy source is not from fusion, but instead from magnetic fields spreads in the galaxy by the supermassive black hole at the center of every galaxy. This idea changes every aspect of astronomy and cosmology. The big bang is no longer necessary to explain the source of the mass in the universe and the expansion of the universe. According to this theory the matter in the universe is created in the cores of stars by conversion of energy to mass. The expansion of the universe is induced by the rapid formation of new galaxies. Stars grow slowly and gradually over tens of billion of years by conversion of energy to mass. The gradual growth of stars and the planet search programs that found hundreds of nearby planets indicate that stars are born from planets. This invalidates the solar nebula hypothesis as the source of the stars and the solar system. Stars fluctuate from a main sequence state to a red giant state. They stay in the main sequence when they receive strong magnetic fields and they turn into a red giant when the magnetic fields are weakened. The sun also fluctuated from a main sequence to a red giant. When the sun was a red giant it had strong solar wind that supplied the material to created the planets. The solar system contains hard evidence that the sun was a red giant, those are short lived isotopes and chondrules. The fact that there is hard evidenced to a red giant sun confirm this theory. Highlights of this theory include the following: 1. The sun energy source is from magnetic fields from the galactic center. 2. The heat induced by the magnetic fields leads to high energy collision between particle in the sun core that creates new particle and increase the sun mass. 3. All the stars in the galaxy create new mass so the total mass and the size of the galaxy is increasing. 4. The stars in the galaxy eject dust that freefall to the galactic center supermassive black hole. Thorough the dynamo effect the gravitational potential energy of the debris and dust is converted to magnetic fields. 5. As the galaxy mass and size increase, globular clusters are detached form the main galaxy to create new galaxies. 6. Galaxies spawn new galaxies and the total number of galaxies in the universe increase. 7. The universe expands and accelerates from the increase in the number of the galaxies. 8. The Big Bang cosmological model is replaced by a new cosmological model that resembles the steady state theory. 9. Stars grow gradually from conversion of energy to mass. 10.Stars are born from planets, they first grow by accretion and then by conversion of energy to mass. 11.Stars fluctuate from main sequence to a red giant. When the magnetic fields are strong the star is in the main sequence, when the magnetic fields are weakened the star turn to a red giant. 12.The sun was a red giant 4.6 billions years ago. 13.The planets were created from the strong solar wind of the red giant sun.

Download or read book The Structure And Evolution Of Stars written by Eldridge J J and published by World Scientific. This book was released on 2018-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stars are the fundamental observable constituents of the Universe. They are the first objects we see in the night sky, they dominate the light produced in our own and other galaxies, and nucleosynthesis in stars produces all the elements heavier than helium. A knowledge of stars and their evolution is vital to understand other astrophysical objects from accreting black holes and galaxies to the Universe itself.The structure of a star can be described mathematically by differential equations derived from the principles of hydrodynamics, electromagnetic theory, thermodynamics, quantum mechanics, atomic and nuclear physics. The basic equations of a spherical star are derived in detail at an accessible level. The topics discussed include modes of energy transport, the equation of state, the physics of the opacity sources and the nuclear reactions. Attention is also given to the virial theorem, polytropic gas spheres and homology principles and the procedure for numerical solution of the equations is outlined. This book tracks the evolution of stars from their main-sequence evolution through the exhaustion of various nuclear fuels to the end points of evolution and also introduces the topic of interacting binary stars. The aim is to take the reader from the essential underlying physical principles to the doors to current research on stellar interiors.

Download or read book The Universe at Large written by Hermann Bondi and published by . This book was released on 1960 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: How large is the universe? How old are the galaxies and stars? How rapidly are the distant galaxies receding from us? Why, if there are countless stars in the universe, is it dark at night? What goes on inside stars... and between them? How did the universe start and where is it going? These are some of the ageless questions Hermann Bondi considers in The Universe at Large, a brilliant speculation on the findings of modern astronomy. Against the background of conflicting "steady-state" and "exploding" theories of the universe, Bondi examines the contributions and insights of men like Einstein, Eddington, Hoyle, Hubble, and Lemaître. Cosmological considerations are brought closer to hand by applying our revised understanding of the universe to natural phenomena -- including the Aurora, sun and moon tides, the earth's magnetism, and the wobble of its axis.

Available in PDF, EPUB and Kindle. Book excerpt: This book traces the development of ideas about the origin of the Solar System from ancient times to the present day. A survey of more modern ideas, covering the last 200 years or so, highlights the difficulties experienced by theories and also points the way towards the development of a more successful theory. In particular, the current OC standard modelOCO OCo the Solar Nebula Theory OCo is examined and discussed in some detail. After more than thirty years of development, this theory has still not settled down into an agreed form, as it experiences both theoretical difficulties and problems with reconciling new observations. By contrast, the Capture Theory, developed over the last forty years by the author, and supported by recent observations provides a complete description of the formation of the Solar System, including an evolutionary hypothesis that explains the detailed structure of the system. Written in an informative yet accessible manner, this book will appeal to both specialist and non-specialist readers alike. Sample Chapter(s). Introduction (47 KB). Chapter 1: Theories Come and Theories Go (94 KB).

This book was released on 2020-09-28 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: When men attained to sufficient intelligence for speculations as to their own nature and that of the earth on which they lived, they must have been profoundly impressed by the nightly pageant of the starry heavens. The intense sparkling brilliancy of Sirius and Vega, the more massive and steady luminosity of Jupiter and Venus, the strange grouping of the brighter stars into constellations to which fantastic names indicating their resemblance to various animals or terrestrial objects seemed appropriate and were soon generally adopted, together with the apparently innumerable stars of less and less brilliancy scattered broadcast over the sky, many only being visible on the clearest nights and to the acutest vision, constituted altogether a scene of marvellous and impressive splendour of which it must have seemed almost impossible to attain any real knowledge, but which afforded an endless field for the imagination of the observer. The relation of the stars to the sun and moon in their respective motions was one of the earliest problems for the astronomer, and it was only solved by careful and continuous observation, which showed that the invisibility of the former during the day was wholly due to the blaze of light, and this is said to have been proved at an early period by the observed fact that from the bottom of very deep wells stars can be seen while the sun is shining. During total eclipses of the sun also the brighter stars become visible, and, taken in connection with the fixity of position of the pole-star, and the course of those circumpolar stars which never set in the latitudes of Greece, Egypt, and Chaldea, it soon became possible to frame a simple hypothesis which supposed the earth to be suspended in space, while at an unknown distance from it a crystal sphere revolved upon an axis indicated by the pole-star, and carried with it the whole host of heavenly bodies. This was the theory of Anaximander (540 B.C.), and it served as the starting-point for the more complex theory which continued to be held in various forms and with endless modifications down to the end of the sixteenth century. It is believed that the early Greeks obtained some knowledge of astronomy from the Chaldeans, who appear to have been the first systematic observers of the heavenly bodies by means of instruments, and who are said to have discovered the cycle of eighteen years and ten days after which the sun and moon return to the same relative positions as seen from the earth. The Egyptians perhaps derived their knowledge from the same source, but there is no proof that they were great observers, and the accurate orientation, proportions, and angles of the Great Pyramid and its inner passages may perhaps indicate a Chaldean architect.

Available in PDF, EPUB and Kindle. Book excerpt: If scientists can’t touch the Sun, how do they know what it’s made of? And if we can’t see black holes, how can we be confident they exist? Gravitational physicist David Garfinkle and his brother, science fiction writer Richard Garfinkle, tackle these questions and more in Three Steps to the Universe, a tour through some of the most complex phenomena in the cosmos and an accessible exploration of how scientists acquire knowledge about the universe through observation, indirect detection, and theory. The authors begin by inviting readers to step away from the Earth and reconsider our Sun. What we can directly observe of this star is limited to its surface, but with the advent of telescopes and spectroscopy, scientists know more than ever about its physical characteristics, origins, and projected lifetime. From the Sun, the authors journey further out into space to explore black holes. The Garfinkle brothers explain that our understanding of these astronomical oddities began in theory, and growing mathematical and physical evidence has unexpectedly supported it. From black holes, the authors lead us further into the unknown, to the dark matter and energy that pervade our universe, where science teeters on the edge of theory and discovery. Returning from the depths of space, the final section of the book brings the reader back down to Earth for a final look at the practice of science, ending with a practical guide to discerning real science from pseudoscience among the cacophony of print and online scientific sources. Three Steps to the Universe will reward anyone interested in learning more about the universe around us and shows how scientists uncover its mysteries.
