This book was released on 2012-07-17 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is the origin of the universe? Are we alone in the Universe? Using clear and plain language, the author explores these two interesting scientific-philosophical themes with a broad range of studies, including astronomy, cosmology, chemistry, biology, geology and planet science.The first part discusses the origins of everything, from the Big Bang to humankind. It follows the long course of evolution — from original matter to the formation of more complex structures, from the furthest galaxies to the nearest stars, from planets to organic molecules, from the first and most elementary forms of life through to the reptiles, the dinosaurs and the advent of man.The second part traces the history of the Earth and evaluates the risks of extinction in the future as predicted by scientists. Is the Earth the only habitable planet in the Universe? This question initiates the discussion on the importance of the Earth's position in the solar system and the significance of our geologically alive planet.The final part is dedicated to the search for extraterrestrial beings with identifiable life forms. It also describes attempts for searching, from the past to the near future.This remarkable book provides the best answers we have to the epic questions about us and our place in the universe.

Download or read book Life in the Cosmos written by Manasvi Lingam and published by Harvard University Press. This book was released on 2021-06-29 with total page 1089 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rigorous and scientific analysis of the myriad possibilities of life beyond our planet. ÒAre we alone in the universe?Ó This tantalizing question has captivated humanity over millennia, but seldom has it been approached rigorously. Today the search for signatures of extraterrestrial life and intelligence has become a rapidly advancing scientific endeavor. Missions to Mars, Europa, and Titan seek evidence of life. Laboratory experiments have made great strides in creating synthetic life, deepening our understanding of conditions that give rise to living entities. And on the horizon are sophisticated telescopes to detect and characterize exoplanets most likely to harbor life. Life in the Cosmos offers a thorough overview of the burgeoning field of astrobiology, including the salient methods and paradigms involved in the search for extraterrestrial life and intelligence. Manasvi Lingam and Abraham Loeb tackle three areas of interest in hunting for life Òout thereÓ: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds, with an eye on the biomarkers that may reveal the presence of microbial life; and finally, the detection of technological signals that could be indicative of intelligence. Drawing on empirical data from observations and experiments, as well as the latest theoretical and computational developments, the authors make a compelling scientific case for the search for life beyond what we can currently see. Meticulous and comprehensive, Life in the Cosmos is a master class from top researchers in astrobiology, suggesting that the answer to our age-old question is closer than ever before.

Download or read book At the Edge of Time written by Dan Hooper and published by Princeton University Press. This book was released on 2019-11-05 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new look at the first few seconds after the Big Bang—and how research into these moments continues to revolutionize our understanding of our universe Scientists in the past few decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: we still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history. Delving into the remarkable science of cosmology, Dan Hooper describes many of the extraordinary and perplexing questions that scientists are asking about the origin and nature of our world. Hooper examines how we are using the Large Hadron Collider and other experiments to re-create the conditions of the Big Bang and test promising theories for how and why our universe came to contain so much matter and so little antimatter. We may be poised to finally discover how dark matter was formed during our universe’s first moments, and, with new telescopes, we are also lifting the veil on the era of cosmic inflation, which led to the creation of our world as we know it. Wrestling with the mysteries surrounding the initial moments that followed the Big Bang, At the Edge of Time presents an accessible investigation of our universe and its origin.

Download or read book Origin of Life via Archaea written by Richard Gordon and published by John Wiley & Sons. This book was released on 2024-08-26 with total page 1190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book surveys the models for the origin of life and presents a new model starting with shaped droplets and ending with life as polygonal Archaea; it collects the most published micrographs of Archaea (discovered only in 1977), which support this conclusion, and thus provides the first visual survey of Archaea. Origin of Life via Archaea’s purpose is to add a new hypothesis on what are called “shaped droplets”, as the starting point, for flat, polygonal Archaea, supporting the Vesicles First hypothesis. The book contains over 6000 distinct references and micrographs of 440 extant species of Archaea, 41% of which exhibit polygonal phenotypes. It surveys the intellectual battleground of the many ideas of the origin of life on earth, chemical equilibrium, autocatalysis, and biotic polymers. This book contains 17 chapters, some coauthored, on a wide range of topics on the origin of life, including Archaea’s origin, patterns, and species. It shows how various aspects of the origin of life may have occurred at chemical equilibrium, not requiring an energy source, contrary to the general assumption. For the reader’s value, its compendium of Archaea micrographs might also serve many other interesting questions about Archaea. One chapter presents a theory for the shape of flat, polygonal Archaea in terms of the energetics at the surface, edges and corners of the S-layer. Another shows how membrane peptides may have originated. The book also includes a large table of most extant Archaea, that is searchable in the electronic version. It ends with a chapter on problems needing further research. Audience This book will be used by astrobiologists, origin of life biologists, physicists of small systems, geologists, biochemists, theoretical and vesicle chemists.

Download or read book Exoplanets written by Michael E. Summers and published by Smithsonian Institution. This book was released on 2017-03-14 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past few years have seen an incredible explosion in our knowledge of the universe. Since its 2009 launch, the Kepler satellite has discovered more than two thousand exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, and even more remarkable than the sheer number of exoplanets is their variety. In Exoplanets, astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space. This captivating book reveals the latest discoveries and argues that the incredible richness and complexity we are finding necessitates a change in our questions and mental paradigms. In short, we have to change how we think about the universe and our place in it, because it is stranger and more interesting than we could have imagined.

Book excerpt: 'VISIONARY' Stephen Greenblatt 'So interesting... I recommend [Extraterrestrial] to people who have any interest in this extraordinary subject of life existing in other places than on Earth.' William Shatner (from Amazon.com) Harvard's top astronomer takes us inside the mind-blowing story of the first interstellar visitor to our solar system In late 2017, scientists at a Hawaiian observatory glimpsed a strange object soaring through our inner solar system. Astrophysicist Avi Loeb conclusively showed it was not an asteroid; it was moving too fast along a strange orbit, and leaving no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his theory and its profound implications: for science, for religion, and for the future of our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars-and to think critically about what's out there, no matter how strange it seems.

Download or read book The Stardust Revolution written by Jacob Berkowitz and published by Rowman & Littlefield. This book was released on 2022-02-15 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1957, as Americans obsessed over the launch of the Soviet Sputnik satellite, another less noticed space-based scientific revolution was taking off. That year, astrophysicists solved a centuries-old quest for the origins of the elements, from carbon to uranium. The answer they found wasn’t on Earth, but in the stars. Their research showed that we are literally stardust. The year also marked the first conference that considered the origin of life on Earth in an astrophysical context. It was the marriage of two of the seemingly strangest bedfellows—astronomy and biology—and a turning point that award-winning science author Jacob Berkowitz calls the Stardust Revolution. In this captivating story of an exciting, deeply personal, new scientific revolution, Berkowitz weaves together the latest research results to reveal a dramatically different view of the twinkling night sky—not as an alien frontier, but as our cosmic birthplace. Reporting from the frontlines of discovery, Berkowitz uniquely captures how stardust scientists are probing the universe’s physical structure, but rather its biological nature. Evolutionary theory is entering the space age. From the amazing discovery of cosmic clouds of life’s chemical building blocks to the dramatic quest for an alien Earth, Berkowitz expertly chronicles the most profound scientific search of our era: to know not just if we are alone, but how we are connected. Like opening a long-hidden box of old family letters and diaries, The Stardust Revolution offers us a new view of where we’ve come from and brings to light our journey from stardust to thinking beings.

Available in PDF, EPUB and Kindle. Book excerpt: Inside the epic quest to find life on the water-rich moons at the outer reaches of the solar system Where is the best place to find life beyond Earth? We often look to Mars as the most promising site in our solar system, but recent scientific missions have revealed that some of the most habitable real estate may actually lie farther away. Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have existed for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out. Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds. Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

Download or read book Before the Big Bang written by Laura Mersini-Houghton and published by HarperCollins. This book was released on 2022-07-19 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A riveting tour of the cosmos from one of the brightest minds in astrophysics." —The Washington Post A revolutionary new account of our universe’s creation—and a breathtaking exploration of the landscape from which we sprang—from one of the world’s most celebrated cosmologists What came before the Big Bang, and what exists outside of the universe it created? Until recently, scientists could only guess at what lay past the edge of space-time. However, as pioneering theoretical physicist Laura Mersini-Houghton explains, new scientific tools are now giving us the ability to peer beyond the limits of our universe and to test our theories about what is there. And what we are finding is upending everything we thought we knew about the cosmos and our place in it. Mersini-Houghton is no stranger to boundaries—or to pushing through them. As a child growing up in Communist Albania, she discovered a universe beyond her walled-off world through the study of math and science, and through music. As a female cosmologist in a male-dominated field, she transcended the limits that society and her profession tried to place on her. And as a trailblazing researcher, she helped to revolutionize the study of our universe by revealing that, far from living in a cosmic Albania, with a world that ends at its borders, we are part of a larger family of universes—a multiverse—that holds wonders we are only beginning to unlock. Mersini-Houghton’s groundbreaking research suggests that we sit in a quantum landscape whose peaks and valleys hide a multitude of other universes, and even hold the secret to the origins of existence itself. Recent evidence has revealed the signatures of such sibling universes in our own night sky, confirming Mersini-Houghton’s theoretical work and offering humbling evidence that our universe is just one member of an unending cosmic family. The incredible scientific saga of one woman’s mind-expanding journey through the multiverse, Before the Big Bang will reshape our understanding of humanity’s place in the unfathomable vastness of the cosmos.
