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?

In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most listeners, this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it appears. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where, at the most fundamental level, time disappears.

Prepare to learn everything we still don’t know about our strange and mysterious Universe. Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore - there are huge yawning voids in our basic notions of how the world works. PHD Comics creator Jorge Cham and particle physicist Daniel Whiteson have teamed up to explore everything we don't know about the Universe: The enormous holes in our knowledge of the cosmos. Armed with entertaining and lucid explanations of science, they give us the best answers currently available.

What is life? This is among the most difficult open problems in science, right up there with the nature of consciousness and the existence of matter. All the definitions we have fall short. None help us understand how life originates or the full range of possibilities for what life on other planets might look like. In Life as No One Knows It, physicist and astrobiologist Sara Imari Walker argues that solving the origin of life requires radical new thinking and an experimentally testable theory for what life is.

We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now?

Unearth the hidden past of Earth and its intricate connection with our galaxy's undisclosed history in this engaging new volume. Presenting a unique blend of scientific evidence, philosophical thought, and spiritual insight, this book unifies these seemingly disparate realms into a coherent narrative. Delve into the profound origins of our species and our celestial lineage, linked to infinite worlds, alternate dimensions, and numerous universes.

More than half a century after humans first walked on the Moon, exciting new space adventures are in the works. Thanks to major advances in rocketry, robotics, and other space technologies, humanity is on the verge of returning to the Moon, exploring Mars, building permanent orbiting space stations, expanding space tourism, and pushing the boundaries of exploration throughout the solar system and beyond. The Future of Space Exploration explores these exciting developments in 12 half-hour episodes, hosted by aerospace engineer and executive Dr. Ariel Ekblaw.

Written in simple and accessible language, this nontechnical introduction to cosmology, or the creation and development of the universe, explains the discipline, covers its history, details the latest developments, and explains what is known, what is believed, and what is purely speculative. In addition, the author discusses the development of the Big Bang theory, and more speculative modern issues like quantum cosmology, superstrings, and dark matter.

In 2017, Avi Loeb, Chair of Harvard's Astronomy Department, went public with a theory that shook the scientific community - our solar system has been visited by advanced alien technology. His provocative and persuasive argument (and internationally bestselling book Extraterrestrial) has opened thousands of minds to the existence of intelligent life beyond Earth. This book tackles the huge question of what happens next?

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

Einstein's theory of gravity, as beautiful as it is, seems to be in direct contradiction with another theory he helped create: quantum mechanics. From the explosions of neutron stars and the collisions of black holes to the modern scientific process as a means to seek truth and understanding in the cosmos, this audiobook takes the listener on a journey of learning and discovery that has been 100 years in the making.

With a foreword from Professor Brian Cox and access to all the latest NASA mission information, Andrew Cohen takes listeners on a voyage of discovery via the probes and telescopes exploring the outer reaches of our galaxy, revealing how it was formed and how it will inevitably be destroyed by the enigmatic black hole at its heart. And beyond our galaxy, the expanding universe, which holds clues to the biggest mystery of all - how did it all begin?

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.

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.

In Beyond Biocentrism, acclaimed biologist Robert Lanza and astronomer Bob Berman take the listener on an intellectual thrill ride as they reexamine everything we thought we knew about life, death, the universe, and the nature of reality itself. The first step is acknowledging that our existing model of reality is looking increasingly creaky in the face of recent scientific discoveries.

This compelling book describes how the Big Bang theory arose, how it has evolved, and why it is the best theory so far to explain the current state of the universe. In addition to understanding the birth of the cosmos, listeners will learn how the theory stands up to challenges and what it fails to explain. Karen Fox provides clear answers to some of the hardest questions including: Why was the Big Bang theory accepted to begin with? Will the Big Bang theory last into the next century or even the next decade? Is the theory at odds with new scientific findings?

What's going on in the sky? Astronomy For Dummies takes you through the solar system, the Milky Way galaxy, and all the way to the outer reaches of the universe. You'll have stars in your eyes as you discover the basics of skywatching, planets, asteroids, black holes, and dark matter. Ponder the deep questions that keep humanity guessing, like, is there anybody out there? Two NASA-award-winning astronomers take you on a tour of outer space that will fascinate you—and, if you're a student, help you through your intro astronomy course.

In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe.

The most trusted explainer of the most mind-boggling concepts pulls back the veil of mystery that has too long cloaked the most valuable building blocks of modern science. Sean Carroll, with his genius for making complex notions entertaining, presents in his uniquely lucid voice the fundamental ideas informing the modern physics of reality. In the tradition of the legendary Richard Feynman lectures presented sixty years ago, this book is an inspiring, dazzling introduction to a way of seeing that will resonate across cultural and generational boundaries for many years to come.
