Astronomers have determined that our universe is 13.7 billion years old. How exactly did they come to this precise conclusion? How Old Is the Universe? tells the incredible story of how astronomers solved one of the most compelling mysteries in science and, along the way, introduces listeners to fundamental concepts and cutting-edge advances in modern astronomy.

It takes a certain amount of courage to step beyond one's day-to-day experiments and look at the big picture - and the origin of the Moon is a big picture question par excellence. Perhaps it makes sense that William Hartmann, one of the two scientists who unraveled the Moon's biggest mystery, is not only a scientist but also a part-time artist and science fiction writer. It took someone with an artist's eye and a fiction writer's speculative temperament to see the big picture....

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.

Letters from the Universe presents a new, simplistic framework for this vast expanse we exist in. By understanding the cosmos and knowing how everything began, we can emulate the ways of the universe and orchestrate a beautiful symphony of life, love, and happiness.

Rope Hypothesis and Thread Theory is based on Bill Gaede's Rope Hypothesis. We apply the rope model to questions such as, what is gravity, light, electricity, and magnetism? What is thermodynamics? What is the difference between light and sound? What is plasma? How do batteries, antennas, and cathode ray tubes work? What is the difference between fundamental and composite objects? Does size scale make a difference when it comes to motion, friction, bending, stretching, and tension?

Were Copernicus, Galileo, and Kepler wrong? Does Earth orbit the Sun, or does the Sun orbit Earth? For centuries, everyone thought the science was settled, but today the accepted cosmology is being challenged by writers, speakers, and movie producers who insist that science took a wrong turn in the 17th century. These new geocentrists claim not only that Earth is the center of our planetary system but that Earth is motionless at the very center of the universe.

Paul Singh and John R. Shook draw on the latest findings from the physical and biological sciences, astronomy and cosmology, geology and genetics, and prehistory and archeology in search of answers. As they lucidly and engagingly demonstrate, the answers science gives about ourselves and the universe in which we live are incomparably more surprising and interesting than any mythical tale about some clash of titans or calculating creator.

Sustainability has become a compelling topic of domestic and international debate as the world searches for effective solutions to accumulating ecological problems. In Return to Nature? An Ecological Counterhistory, Fred Dallmayr demonstrates how nature has been marginalized, colonized, and abused in the modern era.

Visualize and explore the wonders of our universe. Black holes, dark matter, space-time, gravity, light-speed, orbits, photons, dark energy, solar systems, the big bang, expansion, the shape of the universe, and even the multiverse!

An ancient document was found and its basic message is that mankind will be destroyed by an asteroid hitting Earth. To understand and assess the truth of this, Asteroid Impact: Revelation Foretells Our End reviews the purpose of Revelation, who wrote it, and why and how it was written. The book explores the scientific facts upon which the predictions of the Bible are based and analyzes the history of asteroid impacts on Earth in order to assess the accuracy of Biblical predictions.

Were ancient Greek philosophers right about reality being only an illusion? What was really the biggest blunder of Einstein's life? Is everything we've been taught about the universe incorrect? In The Unobservable Universe, visionary scientist and engineer Scott M. Tyson successfully unravels cosmology from the level of rocket science and brings it down to Earth, demystifying the universe in terms that laymen can comprehend and enjoy, splitting atoms but not hairs on this magical mystery tour of the outback of time and space.

Are you all set for an adventure in Uranus? If you are, then hop into our imaginary rocket ship, and let’s blast off to Uranus! Let’s uncover the mysteries of the planet in this attention-grabbing, educational audiobook.

Ragnarok. Armageddon. Doomsday. Since the dawn of time, man has wondered how the world would end. In The Last Three Minutes, Paul Davies reveals the latest theories. Voiced in clear language that makes the cutting-edge science of quarks, neutrinos, wormholes, and metaverses accessible to the layman, The Last Three Minutes treats listeners to a wide range of conjectures about the ultimate fate of the universe.

The hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the universe? Was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our universe. Little wonder the hunt and discovery of this new particle produced such intense media interest.

What is the nature of the material world? How does it work? What is the universe and how was it formed? What is life? Where do we come from and how did we evolve? How and why do we think? What does it mean to be human? How do we know? There are many different versions of our creation story. This book tells the version according to modern science. It is a unique account, starting at the Big Bang and travelling right up to the emergence of humans as conscious intelligent beings, 13.8 billion years later.

Who are we, and how did we get here? These are two of the most fundamental and far-reaching questions facing scientists and cosmologists alike and have rested at the center of human intellectual endeavor since its beginning. They are questions that stretch across numerous disciplines. Philosophy, theology, evolutionary biology, and mathematics are just some of the fields looking to explain the emergence of human life.

Stephen Hawking has dazzled listeners worldwide with a string of best sellers exploring the mysteries of the universe. Now, for the first time, perhaps the most brilliant cosmologist of our age turns his gaze inward for a revealing look at his own life and intellectual evolution. My Brief History recounts Stephen Hawking’s improbable journey, from his postwar London boyhood to his years of international acclaim and celebrity. This concise, witty, and candid account introduces listeners to a Hawking rarely glimpsed in previous books.

Dr. Rupert Sheldrake, one of the world's most innovative scientists, here shows the ways in which science is being constricted by assumptions that have, over the years, hardened into dogmas. Such dogmas are not only limiting, but dangerous for the future of humanity. According to these principles, all of reality is material or physical; the world is a machine, made up of inanimate matter; nature is purposeless; consciousness is nothing but the physical activity of the brain; free will is an illusion; and God exists only as an idea in human minds.

This is an indispensable guide to physics that offers readers an overview of the most popular physics topics written in an accessible, irreverent, and engaging manner while still maintaining a tone of wry skepticism. Even the novice will be able to follow along, as the topics are addressed using plain English and (almost) no equations. Veterans of popular physics will also find their nagging questions addressed, like whether the universe can expand faster than light.

"Imagine if a Martian showed up, all big ears and big nose like a child’s drawing, and he asked to be baptized. How would you react?" Pope Francis posed that question - without insisting on an answer! - to provoke deeper reflection about inclusiveness and diversity in the Church. But it's not the first time that question has been asked.
