An engaging exploration with renowned astronomer Paul Murdin of how life emerged on Earth—and the possibilities that it exists elsewhere There is no more fascinating question than whether or not we are alone in a vast universe. Here, Paul Murdin applies the latest scientific discoveries and theories to inquire whether life exists on other planets and, if so, what forms it might take. Could there be somewhere life as advanced as here on Earth, or are we more likely to find primitive life-forms? Or are we the sole living organisms in a desolate and boundless cosmos? Professor Murdin invites us to join him in exploring an extraordinary array of evidence to determine if there is life elsewhere in the cosmos. He examines the case for life on Mars and Europa and asks whether on Enceladus or Titan we might find the “warm little” pond that Darwin speculated was where life began here on Earth. Describing the cosmic habitats that produce the alien worlds of our solar system and others, he examines the chances of finding life and the prospects for successful communication with an extraterrestrial intelligence.

If extraterrestrials exist, where are they? What is the probability that somewhere out there in the universe an Earth-like planet supports an advanced culture? Why do so many people claim to have encountered Aliens? In this gripping exploration, scientist Don Lincoln exposes and explains the truths about the belief in and the search for life on other planets. In the first half of Alien Universe, Lincoln looks to Western civilization's collective image of Aliens, showing how our perceptions of extraterrestrials have evolved over time. The roots of this belief can be traced as far back as our earliest recognition of other planets in the universe—the idea of them supporting life was a natural progression of thinking that has fascinated us ever since. Our captivation with Aliens has, however, led to mixed results. The world was fooled in the nineteenth century during the Great Moon Hoax of 1835, and many people misunderstood, with calamitous results, Orson Welles's 1938 radio broadcast, The War of the Worlds. Our continuing interest in Aliens is reflected in entertainment successes such as E.T., The X-Files, and Star Trek. The second half of Alien Universe explores the scientific possibility of whether advanced Alien civilizations do exist. For many years, researchers have sought to answer Enrico Fermi’s great paradox—if there are so many planets in the universe and there is a high probability that many of those can support life, then why have we not actually encountered any Aliens? (Apologies to those who are sure we have.) Lincoln describes how modern science teaches us what is possible and what is not in our search for extraterrestrial civilizations. Whether you are drawn to the psychological belief in Aliens, the history of our interest in life on other planets, or the scientific possibility of Alien existence, Alien Universe is sure to hold you spellbound. -- Jocelyne DiRuggiero, Johns Hopkins University

From Brian Greene, one of the world’s leading physicists and author the Pulitzer Prize finalist The Elegant Universe, comes a grand tour of the universe that makes us look at reality in a completely different way. Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world. From the Trade Paperback edition.

Weird Life The Search For Life That Is Very Very Different From Our Own

“Weird indeed, and not a little wonderful.”—Nature In the 1980s and 1990s, in places where no one thought it possible, scientists found organisms they called extremophiles: lovers of extremes. There were bacteria in volcanic hydrothermal vents on the ocean floor, single-celled algae in Antarctic ice floes, and fungi in the cooling pools of nuclear reactors. But might there be life stranger than the most extreme extremophile? Might there be, somewhere, another kind of life entirely? In fact, scientists have hypothesized life that uses ammonia instead of water, life based not in carbon but in silicon, life driven by nuclear chemistry, and life whose very atoms are unlike those in life we know. In recent years some scientists have begun to look for the tamer versions of such life on rock surfaces in the American Southwest, in a “shadow biosphere” that might impinge on the known biosphere, and even deep within human tissue. They have also hypothesized more radical versions that might survive in Martian permafrost, in the cold ethylene lakes on Saturn’s moon Titan, and in the hydrogen-rich atmospheres of giant planets in other solar systems. And they have imagined it in places off those worlds: the exotic ices in comets, the vast spaces between the stars, and—strangest of all—parallel universes. Distilling complex science in clear and lively prose, David Toomey illuminates the research of the biological avant-garde and describes the workings of weird organisms in riveting detail. His chapters feature an unforgettable cast of brilliant scientists and cover everything from problems with our definitions of life to the possibility of intelligent weird life. With wit and understanding that will delight scientists and lay readers alike, Toomey reveals how our current knowledge of life forms may account for only a tiny fraction of what’s really out there.

' This is the story of the author's unique scientific journey with one of the most remarkable men of 20th century science. The journey begins in Sri Lanka, the author's native country, with his childhood acquaintance with Fred Hoyle's writings. The action then moves to Cambridge, where the famous Hoyle–Wickramasinghe collaborations begin. A research programme which was started in 1962 on the carbonaceous nature of interstellar dust leads, over the next two decades, to developments that are continued in both Cambridge and Cardiff. These developments prompt Hoyle and the author to postulate the organic theory of cosmic dust (which is now generally accepted), and then to challenge one of the most cherished paradigms of contemporary science — the theory that life originated on Earth in a warm primordial soup. A Journey with Fred Hoyle is an intriguing book that traces the progress of a collaboration spanning 40 years, through a sequence of personal reflections, anecdotes and reminiscences. Ideas that were thought heretical 25 years ago are now quietly slipping into the domain of orthodox science.

Wickramasinghe and Hoyle's picture of a galaxy teeming with life is a stunning one … The scientific community has come a long way towards Hoyle and Wickramasinghe's position, wholeheartedly embracing the idea of planetary panspermia.”New Scientist “… An enlightening account of a 40-year scientific collaboration between two remarkable men.”Sir Martin Rees Astronomer Royal “The Hoyle-Wickramasinghe collaboration was notable for the daring leaps over knowledge gaps they were prepared to make. This book is a valuable guide to their corpus, and can serve as a source of ideas and speculations.”International Journal of Astrobiology “A Journey with Fred Hoyle is an intriguing, pacey insight into the working of a fertile scientific mind, and especially one focussed on a topic that is not in the mainstream of astronomical and biological endeavour … I enjoyed A Journey with Fred Hoyle greatly.”The Observatory Magazine “This is a fine blend of personal anecdotes, travel impressions, and scientific reporting — interesting, informative, and worth reading.”Choice “This book is of great interest; it is written in an accessible and exciting way; and I recommend it for a broad readership.”Structural Chemistry '

In these lively and fascinating essays, scientists from around the world weigh in on the latest advances in the search for intelligent life in the universe and discuss just what that might look like. Since 2000, science has seen a surge in data and interest on several fronts related to E.T. (extraterrestrials); A.I. (artificial intelligence); and SETI (search for extraterrestrial intelligence). The debate has intensified over whether life exists outside our solar system, what that life would look like, and whether we’ll ever make contact. Included here are essays from a broad spectrum of the scientific community: cosmologists, astrophysicists, NASA planetary scientists, and geneticists, to name just a few, discussing the latest research and theories relating to alien life. Some of the topics include: If life exists somewhere in space, what are the odds that it evolves into something we would recognize as intelligent? What will space travel look like in the future, and will it all be done by cyborg technology? How long until we are ruled by robot overlords? (This is actually a serious consideration.) Are we simply a simulation in the mind of some supreme being, acting out a virtual reality game? For those who have ever wondered, Is there anybody out there? here are the latest theories and evidence that move us closer to answering that question.

Building on quantum physics, Biocentrism turns the planet upside down with the revolutionary view that life creates the universe rather than the other way around. The central claim of Biocentrism is that what is referred to as space and time are forms of animal perception rather than external physical objects. Lanza and Berman take readers on a fascinating journey through a foreign universe - our own - that will alter their perception of reality for ever.
