Planet Formation and Panspermia by Joseph Seckbach,Richard Gordon,Branislav Vukotic Pdf

An in-depth view of the panspermia hypothesis examined against the latest knowledge of planetary formation and related processes. Panspermia is the concept that life can be passively transported through space on various bodies and seed, habitable planets and moons, which we are beginning to learn may exist in large numbers. It is an old idea, but not popular with those who prefer that life on Earth started on Earth, an alternative, also unproven hypothesis. This book updates the concept of panspermia in the light of new evidence on planet formation, molecular clouds, solar system motions, supernovae ejection mechanisms, etc. Thus, it is to be a book about newly understood prospects for the movement of life through space. The novel approach presented in this book gives new insights into the panspermia theory and its connection with planetary formation and the evolution of galaxies. This offers a good starting point for future research proposals about exolife and a better perspective for empirical scrutiny of panspermia theory. Also, the key to understanding life in the universe is to understand that the planetary formation process is convolved with the evolution of stellar systems in their galactic environment. The book provides the synthesis of all these elements and gives the readers an up-to-date insight on how panspermia might fit into the big picture. Audience Given the intrinsic interdisciplinary nature of the panspermia hypothesis the book will have a wide audience across various scientific disciplines covering astronomy, biology, physics and chemistry. Apart from scientists, the book will appeal to engineers who are involved in planning and realization of future space missions.

Ultraviolet Astronomy and the Quest for the Origin of Life by Ana I. Gomez de Castro Pdf

Ultraviolet Astronomy and the Quest for the Origin of Life addresses the use of astronomical observations in the ultraviolet range to better understand the generation of complex, life-precursor molecules. The origin of RNA is still under debate but seems to be related to the generation of pools of complex organic molecules submitted to heavy cycles of solution in water and drying. This book investigates whether these cycles require a planetary surface or may occur in space by examining both the theoretical and observational aspects of the role of UV radiation in the origin of life. This book offers the latest advances in these studies for astronomers, astrobiologists and planetary scientists. Addresses both the theoretical and observational aspects of the role of Ultraviolet (UV) radiation in the origin of life Builds on the requirements to produce prebiotic molecules in space and the implications for the origin of RNA Investigates the use of ultraviolet observations related to planetary system formation, the evolution of young planetary disks, and the interaction of stars with planetary atmospheres

Astronomical Origins of Life by B. Hoyle,N.C. Wickramasinghe Pdf

Living material contains about twenty different sorts of atom combined into a set of relatively simple molecules. Astrobiologists tend to believe that abiotic mater ial will give rise to life in any place where these molecules exist in appreciable abundances and where physical conditions approximate to those occurring here on Earth. We think this popular view is wrong, for it is not the existence of the building blocks of life that is crucial but the exceedingly complicated structures in which they are arranged in living forms. The probability of arriving at biologically significant arrangements is so very small that only by calling on the resources of the whole universe does there seem to be any possibility of life originating, a conclusion that requires life on the Earth to be a minute component of a universal system. Some think that the hugely improbable transition from non-living to living mat ter can be achieved by dividing the transition into many small steps, calling on a so-called 'evolutionary' process to bridge the small steps one by one. This claim turns on semantic arguments which seek to replace the probability for the whole chain by the sum of the individual probabilities of the many steps, instead of by their product. This is an error well known to those bookies who are accustomed to taking bets on the stacking of horse races. But we did not begin our investigation from this point of view.

Our Cosmic Ancestry in the Stars by Chandra Wickramasinghe, Ph.D.,Kamala Wickramasinghe,Gensuke Tokoro Pdf

An exploration of how acceptance of panspermia will soon change history • Offers extensive scientific proof of panspermia--that life arose on Earth via comets and that evolution is seeded by viruses arriving via comets and interstellar dust • Explores the major philosophical, psychological, cultural, religious, and environmental ramifications of the acceptance of this new scientific worldview Mainstream consensus is that life arose on Earth spontaneously out of “primordial soup.” Yet this theory, as well as the Darwinian “survival of the fittest” concept as it relates to major steps in evolution, has no scientific basis or proof. Where, then, did life come from? As the authors show, with conclusive scientific evidence, life came from space--a concept known as “panspermia.” We humans, and all other life on Earth, evolved over millennia in response to viruses that arrived via comets, and we continue to do so. Exploring the philosophical, psychological, cultural, and environmental ramifications of the acceptance of panspermia, the authors show how the shift will be on par with the Copernican Revolution--when it was finally accepted that the Earth was not the center of the Universe. Explaining the origins of the panspermia theory in the work of the late Sir Fred Hoyle, the authors reveal the vast body of evidence that has accumulated over the past 4 decades in favor of the cosmic origins of life, including viral inserts found in DNA that have shaped our human genome over millions of years. They show how the tiniest of viruses, microscopic animals (tardigrades), and even seeds have been found to be natural cosmonauts. The authors also show how space-borne viruses play a crucial role in the positive evolution of life and that our entire existence on this planet is contingent on the continuing ingress of cosmic viruses. Revealing how panspermia offers answers to some of humanity’s longstanding questions about the origins of life, the authors discuss the impact this shift in understanding will have on our relationship with the Earth and on culture, history, and religion. And perhaps the most dramatic ramification of all is that acceptance of panspermia means acceptance that Earth is not unique--that other life-filled planets exist and intelligent life is common in the Universe. Not only did we come from space, but we are not alone.

Planet Formation by Wolfgang Brandner Pdf

When this book was published in 2006, it had been just over ten years since the first planet outside our solar system was detected. Since then, much work has focused on understanding how extrasolar planets may form, and discovering the frequency of potentially habitable Earth-like planets. This volume addresses fundamental questions concerning the formation of planetary systems in general, and of our solar system in particular. Drawing from advances in observational, experimental and theoretical research, it summarises our understanding of the planet formation processes, and addresses major open questions and research issues. Chapters are written by leading experts in the field of planet formation and extrasolar planet studies. The book is based on a meeting held at Ringberg Castle in Bavaria, where experts gathered together to present and exchange their ideas and findings. It is a comprehensive resource for graduate students and researchers, and is written to be accessible to newcomers to the field.

Ancient Alien Ancestors by Will Hart Pdf

Explores evidence for the theory of directed panspermia--that life on Earth and the landscape of Earth itself was engineered by extraterrestrials • Details how the Earth was terraformed through a sophisticated geo-engineering program, providing clear examples such as the precise mathematical longitude configurations of the Great Pyramid of Giza with the major rivers on Earth • Shows how our spectrum of blood types supports the theory of panspermia while directly contradicting the conventional “out of Africa” theory of evolution • Examines the strongest modern UFO accounts, including the Russian Roswell case, as well as the suppressed UFO sightings of NASA astronauts In the early 1970s, Nobel Prize-winning DNA co-discoverer Sir Francis Crick and his colleague Leslie Orgel proposed that in the distant past, an extraterrestrial race sent a spacecraft loaded with microorganisms to seed the Earth with life. Now, more than 40 years later, the fields of space research and biotechnology have advanced to the point where they can back up Crick and Orgel’s claims about our ancient alien ancestors. Sharing scientific evidence of alien involvement with life on our planet and with the very landscape of Earth itself, Will Hart refines the theory of directed panspermia--that life was intentionally seeded on Earth by extraterrestrials--to reveal that the same ET agency also created humans and generated civilization. He shows how the Earth was terraformed through an engineering program so sophisticated and vast that it has escaped our attention so far--for example, the major rivers on Earth are precisely aligned through geo-engineering with the Great Pyramid of Giza. Revealing the Great Pyramid as an alien message in stone, the author explains how the Giza pyramids could not have been built by the ancient Egyptians and examines the extraterrestrial energy technologies used to move the pyramids’ massive stone blocks, methods later rediscovered by Nikola Tesla and the builder of Coral Castle, Edward Leedskalnin. He details how an advanced race implanted the basic genome on Earth as well as genetically engineered the human race and shows how our spectrum of blood types supports the theory of panspermia while directly contradicting the conventional “out of Africa” theory of evolution. Investigating how the extraterrestrial agency behind the origin of civilization is still working behind the scenes today, the author examines the strongest modern UFO accounts, including the Russian Roswell case and the suppressed UFO sightings of NASA astronauts. He shows that this advanced ET civilization is not an alien race in the way we normally think of “aliens”--they are our ancestors and as human as we are.

On the Origin of Planets by M. M. Woolfson Pdf

The book begins with a historical review of four major theories for the origin of the Solar System in particular, or of planets in general, which highlight the major problems that need to be solved by any plausible theory. In many theories, including that which form the major theme of this book, the formation of planets and stars is intimately linked, so four chapters are devoted to the processes that can be described as the birth, life and death of stars. Recent observations that have revealed the existence of planets around many Sun-like stars are described in detail, followed by a clear exposition of the Capture Theory for the origin of planets. Many aspects of this theory are illustrated with sophisticated computer modelling that convincingly demonstrates the plausibility of the theory. The Capture Theory is in complete accord with all observations, including the estimate it gives for the proportion of Sun-like stars with planets. It is the only theory that sits comfortably with all present observational and theoretical constraints. The general theory of planet formation does not explain the detailed structure of the Solar System. An early postulated collision of two major planets is shown to explain many disparate features of the Solar System the nature of the terrestrial planets, surface features of the Moon and its relationship with Earth, asteroids, comets and dwarf planets, the relationship between Neptune, Triton and Pluto and the characteristics of meteorites, including the isotopic anomalies found in them. The postulate of a planetary collision is given support by a 2009 NASA observation of the residue of such an event around a distant young star.

Comets and the Origin of Life by Janaki Wickramasinghe,Chandra Wickramasinghe,William Napier,Bill Napier Pdf

The idea that comets may be connected with the origin of life on Earth was considered heresy a few decades ago, with scientists shying away from this possibility as if from a medieval superstition. However the case that comets may have contributed at least the complex organic building blocks of life has become very strong, and mechanisms have now been identified whereby comets may incubate and transfer microbial life from one cosmic habitat to another in the Galaxy. The latter process cometary panspermia was pioneered by the late Sir Fred Hoyle and one of the present authors in the early 1980's. A theory that was once controversial is slowly gaining scientific respectability and support.The recent surge of interest in astrobiology has led to a spate of books in astrobiology -- combining astronomy and biology -- but in most of these, cometary panspermia is dealt with only cursorily. The present book sets out the case for cometary panspermia in a cogent way, combining evidence from space science, celestial mechanics, geology and microbiology. It should be an essential part of any university course on astrobiology, and also serve as a reference textbook for researchers in the field.

Impact by Greg Brennecka Pdf

A Short History of Nearly Everything meets Astrophysics for People in a Hurry in this humorous, accessible exploration of how meteorites have helped not only build our planet but steered the evolution of life and human culture. The Solar System. Dinosaurs. Donkey Kong. What is the missing link? Surprisingly enough, it's meteorites. They explain our past, constructed our present, and could define our future. Impact argues that Earth would be a lifeless, inhospitable piece of rock without being fortuitously assaulted with meteorites throughout the history of the planet. These bombardments transformed Earth’s early atmosphere and delivered the complex organic molecules that allowed life to develop on our planet. While meteorites have provided the raw materials for life to thrive, they have radically devastated life as well, most famously killing off the dinosaurs and paving the way for humans to evolve to where we are today. As noted meteoriticist Greg Brennecka explains, meteorites did not just set us on the path to becoming human, they helped direct the development of human culture. Meteorites have influenced humanity since the start of civilization. Over the centuries, meteorite falls and other cosmic cinema have started (and stopped) wars, terrified millions, and inspired religions throughout the world. With humor and an infectious enthusiasm, Brennecka reveals previously untold but important stories sure to delight and inform readers about the most important rocks on Earth.
