Book Description
From supernovae and gamma-ray bursts to the accelerating Universe, this is an exploration of the intellectual threads that lead to some of the most exciting ideas in modern astrophysics and cosmology. This fully updated second edition incorporates new material on binary stars, black holes, gamma-ray bursts, worm-holes, quantum gravity and string theory. It covers the origins of stars and their evolution, the mechanisms responsible for supernovae, and their progeny, neutron stars and black holes. It examines the theoretical ideas behind black holes and their manifestation in observational astronomy and presents neutron stars in all their variety known today. This book also covers the physics of the twentieth century, discussing quantum theory and Einstein's gravity, how these two theories collide, and the prospects for their reconciliation in the twenty-first century. This will be essential reading for undergraduate students in astronomy and astrophysics, and an excellent, accessible introduction for a wider audience.

Book Description
Scientific proof validating the legends and myths of ancient floods, fires, and weather extremes • Presents scientific evidence revealing the cause of the end of the last ice age and the cycles of geological events and species extinctions that followed • Connects physical data to the dramatic earth changes recounted in oral traditions around the world • Describes the impending danger from a continuing cycle of catastrophes and extinctions There are a number of puzzling mysteries in the history of Earth that have yet to be satisfactorily explained by mainstream science: the extinction of the dinosaurs, the vanishing of ancient Indian tribes, the formation of the mysterious Carolina Bays, the disappearance of the mammoths, the sudden ending of the last Ice Age, and the cause of huge underwater landslides that sent massive tsunamis racing across the oceans millennia ago. Eyewitness accounts of these events are chronicled in rich oral traditions handed down through generations of native peoples. The authors’ recent scientific discoveries link all these events to a single cause. In The Cycle of Cosmic Catastrophes Richard Firestone, Allen West, and Simon Warwick-Smith present scientific evidence about a series of prehistoric cosmic events that explains why the last Ice Age ended so abruptly. Their findings validate the ubiquitous legends and myths of floods, fires, and weather extremes passed down by our ancestors and show how these legendary events relate to each other. Their findings also support the idea that we are entering a thousand-year cycle of increasing danger and possibly a new cycle of extinctions.

Book Description
In the vast realm of outer space, accidents happen all the time. Things bump into each other. Stars blow up. Space rocks smash into planets. Black holes gobble up everything in their path. The sun is burning out. A comet swarm is bearing down. Any of this could change—or even eliminate—life on a planet like Earth. Countdown to cosmic catastrophes! From asteroid hit to alien invasion, astronomer David Aguilar builds the scientific case for seven extreme events that could impact Earth. (Though not as we know it: most of these catastrophes are way down the cosmic line . . . we hope!) He tells an exciting nonfiction story about how and why these space catastrophes could happen and then creates beautiful, original art to show just how devastatingly spectacular it will be when any one of these seven “big ones” hit! The SMITHSONIAN INSTITUTION is the world’s largest museum and research complex. Founded in 1846, it includes nineteen museum and galleries, the National Zoological Park, and nine research facilities. Its vast collections house 138 million artifacts, specimens, and works of art, which represent our nation’s rich heritage, art from across the globe, and the immense diversity of the natural and cultural world.

Book Description
The search for life in the universe is one of the most challenging topics of science. It is not a modern topic at all, since more than 100 years ago, it was speculated that on the Moon, there are oceans and seas; on Venus, there are swamps and also Mars is inhabitated. However, now we have the scienti?c background and the scienti?c tools to answer this question and it is also certain that the answer would have deep imp- cations for our culture, philosophy, and religions. If we ?nd that life has developed on other planets or satellites of giant planets, then this would be the ?nal breakdown of our central position in the universe. But is life a widespread phenomenon? How vulnerable is it to changing conditions and even catastrophic events? These topics will be discussed in this book. If life is in the extreme case a unique phenomenon found only on planet Earth, which seems to be highly unrealistic, then also it is important to discuss how it is adaptable to changing external conditions. Can we survive a cosmic catastrophe? How do these catastrophes change habitability? Which forms of life are more v- nerable? It was mentioned that now science has made great progress to answer such qu- tions. Let us give some examples. In modern biology, in connection with organic chemistry, the origin of life is studied.

Book Description
Follow this multi-disciplinary, scientific study as it examines the evidence of a great global catastrophe that occurred only 11,500 years ago. Crustal shifting, the tilting of Earth's axis, mass extinctions, upthrusted mountain ranges, rising and shrinking land masses, and gigantic volcanic eruptions and earthquakes--all indicate that a fateful confrontation with a destructive cosmic visitor must have occurred. The abundant geological, biological, and climatological evidence from this dire event calls into question many geological theories and will awaken our memories to our true--and not-so-distant--past.

Book Description
Take a look at the science behind the Mayan calendar, prophecies and mythology. The Maya believed multiple cycles governed civilization. They created various calendars to track these cycles. Their short count calendar tracked a 256-year cycle believed to control epidemics, famines, warfare and more. Scientists have found a 250-year solar cycle that also appears to affect epidemics, famines, warfare and more. Their long count calendar tracked a 5000-year cycle related to natural disasters and cosmic catastrophes. Scientists have also discovered that the Earth is subjected to periodic bombardment by comets and asteroids that plunges the world into long periods of darkness and cold. Mayan mythology appears to record such events and in some instances even the exact dates on which these catastrophes occurred in the past. By comparing these dates with ice core records, sedimentary records, and climate records, this book reveals the truth about civilization's darkest days. And what may lie ahead in the future.
