Cosmic Search

The search -- Discoveries -- Observation -- Detection, recognition, and classification of cosmic phenomena -- The fringes of legitimacy : the need for enlightened planning.

This book takes the reader on an exploration of the structure and evolution of our universe. The basis for our knowledge is the Big Bang theory of the expanding universe. This book then tells the story of our search for the first stars and galaxies using current and planned telescopes. These telescopes are marvels of technology far removed from Galileo's first telescope but continuing astronomy in his ground breaking spirit. We show the reader how these first stars and galaxies shaped the universe we see today. This story is one of the great scientific adventures of all time.

Stenger alternates his discussions of popular spirituality with a survey of what the findings of 20th-century physics actually mean in laypersons terms--without equations.

Is time an endlessly repeating circle, or is it a descending path leading to decay and destruction? Is it a uniform stream, or is it made of tiny discrete parcels? Drawing from literature, biology, philosophy, psychology, and theology, this intriguing work explores each of these possible models and relates them to our own subjective impressions of time. Theoretical physicists are now striving to unlock the very structure of time itself. But the quest to understand time has never been the exclusive domain of science. From the Hindu notion of cosmic rebirth to Stephen Hawking's recent studies, philosophers and scientists alike have sought to answer time's riddle. Here is the first accessible, math-free introduction to the competing models of time that demonstrates how today's theories mirror ancient debates over the "shape" of time. This book explores such provocative concepts as synchronicity, time travel, black holes, and artificial intelligence. It probes the ultimate questions of science and philosophy, surveys the frontiers of theoretical physics, and finally, demonstrates how our own personal views on mortality must affect our choice of a scientific model of time.

In Cosmic Company, Seth Shostak and Alex Barnett ponder the possibility of aliens visiting the Earth, as well as the consequences of receiving a signal from the cosmos proving we're neither alone, nor the most intelligent life forms. They explain why scientists think life might exist on other worlds, and how we might contact it. Shostak and Barnett, experienced writers of popular astronomy, provide an accessible overveiw of the science and technology behind the search for life in the universe. Seth Shostak is a Senior Astronomer at the SETI Institute where he is involved in many of the outreach activities of the Institute, including editing the newsletter, overseeing the Web site, giving talks and writing magazine articles about SETI. He also teaches several informal education classes on astronomy and other topics in the Bay Area. Before coming to SETI, Seth did research work on galaxies using radio telescopes at observatories and universities in America and Europe. Alex Barnett is Programme Director at the National Space Centre. She is well-known in the science centre, planetarium and media worlds, particularly for public and educational programmes involving space and astronomy. She presents BBC's Final Frontier a space and astronomy programme.

Searching for Dark Matter with Cosmic Gamma Rays summarizes the evidence for dark matter and what we can learn about its particle nature using cosmic gamma rays. It has almost been 100 years since Fritz Zwicky first detected hints that most of the matter in the Universe that doesn't directly emit or reflect light. Since then, the observational evidence for dark matter has continued to grow. Dark matter may be a new kind of particle that is governed by physics beyond our Standard Model of particle physics. In many models, dark matter annihilation or decay produces gamma rays. There are a variety of instruments observing the gamma-ray sky from tens of MeV to hundreds of TeV. Some make deep, focused observations of small regions, while others provide coverage of the entire sky. Each experiment offers complementary sensitivity to dark matter searches in a variety of target sizes, locations, and dark matter mass scales. We review results from recent gamma-ray experiments including anomalies some have attributed to dark matter. We also discuss how our gamma-ray observations complement other dark matter searches and the prospects for future experiments.

“Some of the most compelling, cutting-edge ideas about who we are and what kind of world we live in. This is a daring book—and a great read!”—Glenn Hartelius, PhD, coeditor of the International Journal of Transpersonal Studies Have you ever looked up at the night sky and wondered “What is the universe?” In this lively and engaging collection of interviews, astronomer Stephan Martin talks with some of today’s most innovative and cutting-edge thinkers on the nature of the universe and our relationship to it. Scientists, mystics, indigenous elders, and cultural creatives all share their unique voices on the nature of reality, the interplay of science and religion, the future of humanity, and the role of each person in a mysterious and evolving universe. Filled with rich insight, dynamic discussion, and penetrating wisdom, Cosmic Conversations asks the fundamental questions about the universe many of us have wondered about, yet few have explored in-depth, questions such as: Do time, space, and matter really exist? Can the universe be inside us, outside us, or both? Is the universe alive, conscious, and intelligent? Where are we in the cosmic evolutionary picture? A compelling journey from the farthest reaches of outer space to the innermost realms of the human heart, Cosmic Conversations will change the way you look at the universe (and yourself) forever. “An excellent contribution to the philosophical revival that is taking place in the marketplace of ideas. Stephan’s searching and heartfelt questions bring out the best of the authors he interviews.”—Steve McIntosh, author of The Presence of the Infinite

A fun, dazzling exploration of the strange numbers that illuminate the ultimate nature of reality. For particularly brilliant theoretical physicists like James Clerk Maxwell, Paul Dirac, or Albert Einstein, the search for mathematical truths led to strange new understandings of the ultimate nature of reality. But what are these truths? What are the mysterious numbers that explain the universe? In Fantastic Numbers and Where to Find Them, the leading theoretical physicist and YouTube star Antonio Padilla takes us on an irreverent cosmic tour of nine of the most extraordinary numbers in physics, offering a startling picture of how the universe works. These strange numbers include Graham’s number, which is so large that if you thought about it in the wrong way, your head would collapse into a singularity; TREE(3), whose finite nature can never be definitively proved, because to do so would take so much time that the universe would experience a Poincaré Recurrence—resetting to precisely the state it currently holds, down to the arrangement of individual atoms; and 10^{-120}, measuring the desperately unlikely balance of energy needed to allow the universe to exist for more than just a moment, to extend beyond the size of a single atom—in other words, the mystery of our unexpected universe. Leading us down the rabbit hole to a deeper understanding of reality, Padilla explains how these unusual numbers are the key to understanding such mind-boggling phenomena as black holes, relativity, and the problem of the cosmological constant—that the two best and most rigorously tested ways of understanding the universe contradict one another. Fantastic Numbers and Where to Find Them is a combination of popular and cutting-edge science—and a lively, entertaining, and even funny exploration of the most fundamental truths about the universe.
