Every year Earth is bombarded with about 40,000 tons of extraterrestrial material. This includes microscopic cosmic dust particles shed by comets and asteroids in outer space, meteorites, as well as large comets and asteroids that have led to catastrophic events in the geologic past. Originally considered only a curiosity, extraterrestrial matter found on Earth provides the only samples we have from comets, asteroids and other planets. Only recently mankind has started to actively collect extraterrestrial matter in space (Apollo program, Stardust mission) rather than to wait for its delivery to Earth. Still, most of our knowledge of the origin and evolution of our solar system is based on careful studies of meteorites, cosmic dust, and traces of large impact events in the geologic record such as the mass extinction that terminated the Cretaceous Period and led to the extinction of the dinosaurs. This book summarizes our current knowledge of the properties, origin, orbital evolution and accretion mechanism of extraterrestrial matter accreted on Earth and sheds light on accretion processes and fluxes in the geologic past. The chapters in the first part of the book are arranged in order to follow extraterrestrial matter from its origin in space, its orbital evolution on its way to Earth, its interaction with the Earth magnetosphere and atmosphere to its more or less violent collision with the Earth's surface. In the second part of the book several chapters deal with the present?day flux of cosmic dust and meteorites to Earth. Finally, several chapters deal with the reconstruction of the accretion history of extraterrestrial matter on Earth, starting with the most recent geologic past and ending with the very early, violent accretion period shortly after the formation of Earth, Moon and other solid planets in our solar system.

This book is a collection of essays written by the very scientists and engineers who have led, and continue to lead, the scientific quest known as SETI, the search for extraterrestrial intelligence. Divided into three parts, the first section, ‘The Spirit of SETI Past’, written by the surviving pioneers of this then emerging discipline, reviews the major projects undertaken during the first 50 years of SETI science and the results of that research. In the second section, ‘The Spirit of SETI Present’, the present-day science and technology is discussed in detail, providing the technical background to contemporary SETI instruments, experiments, and analytical techniques, including the processing of the received signals to extract potential alien communications. In the third and final section, ‘The Spirit of SETI Future’, the book looks ahead to the possible directions that SETI will take in the next 50 years, addressing such important topics as interstellar message construction, the risks and assumptions of interstellar communications, when we might make contact, what aliens might look like and what is likely to happen in the aftermath of such a contact.

Extraterrestrial Altruism examines a basic assumption of the Search for Extraterrestrial Intelligence (SETI): that extraterrestrials will be transmitting messages to us for our benefit. This question of whether extraterrestrials will be altruistic has become increasingly important in recent years as SETI scientists have begun contemplating transmissions from Earth to make contact. Technological civilizations that transmit signals for the benefit of others, but with no immediate gain for themselves, certainly seem to be altruistic. But does this make biological sense? Should we expect altruism to evolve throughout the cosmos, or is this only wishful thinking? Is it dangerous to send messages to other worlds, as Stephen Hawking has suggested, or might humankind benefit from an exchange with intelligence elsewhere in the galaxy? Would extraterrestrial societies be based on different ethical principles, or would we see commonalities with Earthly notions of morality? Extraterrestrial Altruism explores these and related questions about the motivations of civilizations beyond Earth, providing new insights that are critical for SETI. Chapters are authored by leading scholars from diverse disciplines—anthropology, astronomy, biology, chemistry, computer science, cosmology, engineering, history of science, law, philosophy, psychology, public policy, and sociology. The book is carefully edited by Douglas Vakoch, Director of Interstellar Message Composition at the SETI Institute and professor of clinical psychology at the California Institute of Integral Studies. The Foreword is by Frank Drake. This interdisciplinary book will benefit everybody trying to understand whether evolution and ethics are unique to Earth, or whether they are built into the fabric of the universe.

Communication with Extraterrestrial Intelligence is devoted to the concepts and studies related to the science, technology, and observational techniques of communication with extraterrestrial intelligence (CETI). Topics covered range from the search for extraterrestrial intelligence (SETI) to the theory of interstellar communication; the problem of the origin of life; radio signals from extraterrestrial civilizations; and interstellar communication by neutrino beams. An infinitely expandable space radiotelescope is also described. This book is comprised of 21 chapters and opens with a discussion on the CETI activities of the International Academy of Astronautics (IAA) from 1965 to 1976 and describes the outlook for the IAA CETI Standing Committee. The following chapters sketch the background and rationale for a SETI program; the significance of the detection of signals and of information that may be contained in signals from extraterrestrial civilizations; an extended Drake's equation, the longevity-separation relation, equilibrium, inhomogeneities, and chain formation; and the physical and psychological basis for the belief that a band of frequencies called the water hole is a prime band for SETI. This monograph will appeal to practitioners in the fields of astrophysics, astronomy, planetary formation, exobiology, and biological evolution.

The author shares many encounters that made him lean towards the studies of intuitive feelings as well as the psychic phenomena that relate to the mystifying world of the unknown. He had been in the quandary in his early years regarding the paranormal happenings in his life. Rather than ignore them as skeptics do, Torrevillas regarded them with more significance in his life. Author: Did the voice that talked to me when I was 20 years old, the possession by a spirit when I was 30, the appearance of Jesus Christ in the cloud when I was 48, and a lot more, were done by an extraterrestrial beings? The two humanoid angels that saved me when I had undergone open heart surgery? The being that grabbed my hair and pulled my leg recently was the same guide that had watched me throughout my life? At 75 years of age, it was clear that benevolent extraterrestrials had guided me through the years. Now I am called to write this book. The famous American Sleeping prophet, Edgar Cayce, said the past, present and the future are one. In the future we will live and see the beauty of the Universe in this infinite cycle of time- space. But we are hindered in our quest for truth! From Who? You will find the answer in this Book.
