In his phenomenal bestseller A Brief History of Time, Stephen Hawking literally transformed the way we think about physics, the universe, reality itself. In these thirteen essays and one remarkable extended interview, the man widely regarded as the most brilliant theoretical physicist since Einstein returns to reveal an amazing array of possibilities for understanding our universe.

The product of research around the globe and interviews with dozens of prominent scientists, God's Equation tells us it is almost as though Einstein were God's mouthpiece, revealing the most fundamental truths about our larger environment, truths scientists are just now confirming.

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.

Encounters at the Heart of the World concerns the Mandan Indians, iconic Plains people whose teeming, busy towns on the upper Missouri River were, for centuries, at the center of the North American universe. We know of them mostly because Lewis and Clark spent the winter of 1804-1805 with them, but why don't we know more? Who were they really? In this extraordinary book, Elizabeth A. Fenn retrieves their history by piecing together important new discoveries in archaeology, anthropology, geology, climatology, epidemiology, and nutritional science.

Humanity has long looked to the sky and marveled at the world around us. We've wondered why the world is the way it is and whether it has to be that way. And we dream of a time when we have developed a theory of everything—a theory that answers all questions. Einstein's Unfinished Dream explores the cutting-edge research of modern particle physicists that pushes us slowly towards a theory of everything....

Of all the many unexplained phenomena, experiences, and objects in the world, the ones that hold a great deal of fascination for most people are known as "ancient anomalies". These are ancient objects by scientific measure but in form or construction that appear to be relatively modern. They are impossible fossils, out-of-time technology, anachronistic artifacts, or even ancient ruins. In other words, if our history of the world is correct, they just should not exist.

You are reading the word now right now. But what does that mean? What makes the ephemeral moment "now" so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. Einstein showed that the flow of time is affected by both velocity and gravity, yet he despaired at his failure to explain the meaning of now. Equally puzzling: Why does time flow? Some physicists have given up trying to understand and call the flow of time an illusion.

A Mysterious Universe introduces the fundamental laws of quantum mechanics, theory of relativity, and cosmology to a novice in simple language. This concise book deals with deep issues related to the mysteries of modern physics.

How big is the universe? In the early twentieth century, scientists took sides. One held that the entire universe was contained in the Milky Way galaxy. Their champion was the strong-willed astronomer Harlow Shapley. Another camp believed that the universe was so vast that the Milky Way was just one galaxy among billions—the view that would prevail, proven by the equally headstrong Edwin Hubble.

What is space? It isn't a question that most of us normally stop to ask. Space is the venue of physics; it's where things exist, where they move and take shape. Yet over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time. The phenomenon - the ability of one particle to affect another instantly across the vastness of space - appears to be almost magical.

Icy, rocky, sometimes dusty, always mysterious – comets and asteroids are among the Solar System's very oldest inhabitants, formed within a swirling cloud of gas and dust in the area of space that eventually hosted the Sun and its planets. Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants.

Have you ever wondered why you exist? What had to happen for you to be alive and conscious? Scientists have come a long way in answering this question, and this book describes what they have found out. It also examines whether our existence was inevitable at the universe's birth 13.77 billion years ago—or whether we are just incredibly lucky. The book is aimed at those who are interested in science but are not experts.

On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference - a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke’s goal in making a black hole “visible” for the first time, he recognizes that the photo itself asks more questions for humanity than it answers.

A respected physics professor and author breaks down the great debate over the big bang and the continuing quest to understand the fate of the universe.

In his last book, Neil Shubin delved into the amazing connections between human anatomy—our hands, our jaws—and the structures in the fish that first took over land 375 million years ago. Now, with his trademark clarity and exuberance, he takes an even more expansive approach to the question of why we are the way we are.

Trained as a musician, amateur scientist William Herschel found international fame after discovering the planet Uranus in 1781. Though he is still best known for this finding, his partnership with his sister Caroline yielded groundbreaking work, including techniques that remain in use today. The duo pioneered comprehensive surveys of the night sky, carefully categorizing every visible object in the void. Caroline wrote an influential catalogue of nebulae, and William discovered infrared radiation.

Mapping the Heavens provides a tour of the "greatest hits" of cosmological discoveries - the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is at the forefront of the research - an astrophysicist who literally creates maps of invisible matter in the universe.

Instruments of modern physics can measure the energies of the electromagnetic spectrum, but these energies only account for roughly 4 percent of the total identifiable mass-energy of the universe. What makes up the remaining 96%? In this scientifically based yet accessible analysis, Yury Kronn, Ph.D., explores the nature of the remaining 96% of the universe’s mass-energies. Contemporary science calls this mass energy “dark matter,” and the ancients called it life force, prana, or chi.

Two bestselling authors first met in a televised Caltech debate on “the future of God,” one an articulate advocate for spirituality, the other a prominent physicist. This remarkable book is the product of that serendipitous encounter and the contentious - but respectful - clash of worldviews that grew along with their friendship.

Humanity has reached a critical moment. Our world is unsettled and rapidly changing, and we face existential risks over the next century. Various outcomes - good and bad - are possible. Yet our approach to the future is characterized by short-term thinking, polarizing debates, alarmist rhetoric, and pessimism. In this short, exhilarating book, renowned scientist and best-selling author Martin Rees argues that humanity’s prospects depend on our taking a very different approach to planning for tomorrow.
