What astronauts' extraordinary experiences of awe and humility teach us about humanity. What is it like to stand in the shadow of Earth and the Moon and look out at the vastness of the Milky Way? To confront a view so grand it cannot be reproduced in a photo? These are the questions space...

In one of the most exciting and accessible explanations of The Theory of Relativity in recent years, Professors Brian Cox and Jeff Forshaw go on a journey to the frontier of 21st century science to consider the real meaning behind the iconic sequence of symbols that make up Einstein's most...

For half a century, Vega was the most trusted star in astronomy—the zero point of the brightness scale, the calibration standard for every major telescope, the benchmark of stellar normalcy. Then, in 2006, two independent teams of astronomers discovered that everything we believed about it was wrong. Vega is not a calm, slowly spinning star.

The iron in your blood was forged in the nuclear furnace of a dying star. The gold in your jewelry was born in the collision of neutron stars so violent it sent ripples through spacetime itself. The carbon in your DNA survived a stellar explosion and a billion-year journey through space before becoming part of you. Born from Catastrophe reveals the extraordinary truth behind these statements: we are not just made of stardust, but of stardust created through the most violent events in the universe.

Cynthia Sue Larson describes how the Mandela Effect is much more than “false collective memory,” providing a rich tapestry of historical and scientific background as to how this phenomenon is observed.

Erika Hamden, a renowned astrophysicist and educator, brings her passion for space to life in this engaging book. With years of experience studying the cosmos, Hamden specializes in making complex topics fun and easy to understand.

Sixty-six million years ago an asteroid as large as Mt. Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet. Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires. This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.

Are we alone in the universe? It's a fundamental question for Earth-dwelling humankind. Are there other worlds like ours, out there somewhere? In Hidden in the Heavens, Jason Steffen, a former scientist on NASA's Kepler mission, describes how that mission searched for planets orbiting Sun-like stars—especially Earth-like planets circulating in Earth-like orbits.

Scientists tell us that ninety-six percent of the universe is unexplained dark matter and dark energy. Also, they admit that no unifying “theory of everything” exists in physics. This shaky foundation is the basis of modern thinking about the cosmos and Earth’s place in it. Something big seems to be missing. Thus, we’re left with no choice but to question the “consensus” cosmological model. Are we really flying through space on a spinning ball within an expanding universe, while free-falling around the Sun—all as a consequence of a “Big Bang” that supposedly occurred 13.8 billion years ago?

In this illuminating audiobook, Tyson and coauthor James Trefil, a renowned physicist and science popularizer, take on the big questions that humanity has been posing for millennia - How did life begin? What is our place in the universe? Are we alone? - and provide answers based on the most current data, observations, and theories.

In this 24-lesson course aimed at non-scientists, noted particle physicist Dr. Don Lincoln of Fermi National Accelerator Laboratory covers more than a century of progress in physics, describing exactly how scientists reach the conclusions they do. He starts with the atom, which was long hypothesized but wasn’t definitively proven until a paper by Albert Einstein in 1905. That was just the beginning, as researchers probed ever deeper into the atom’s complex structure, leading to the weird findings of quantum mechanics.

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

Over the years, color has dazzled, enhanced, and clarified the world we see. The experimental palettes of painting, the advent of the color photograph, Technicolor pictures, color printing, and so on have created a vivid and vibrant continuum. These ways of representing reality in “living color” echo our evolutionary reliance on and indeed privileging of color as a complex and vital form of consumption, classification, and creation. It’s everywhere we look, yet do we really know much of anything about it?

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...

A boundary-breaking astrophysicist reimagines the universe—and our place within it—in this audacious journey through the Nine Realms of the cosmos. The universe gave rise to everything: stars and cells, minds and memories, purpose and pain. But it doesn’t care about us. It follows its own...

We have mapped the surface of Mars with greater precision than the floor of our own oceans. We predict the weather on Jupiter but cannot say when the next earthquake will strike. We speak of the planet’s future with the confidence of prophets—yet we do not know where the water came from, why heavy elements sit in the crust instead of sinking to the core, or how the first living cell assembled itself from dust. Dust and Time is a sweeping, unflinching exploration of the vast territories of geological ignorance that modern science has papered over with confident models and apocalyptic headlines.

Universe 25 meets quantum physics. In 1968, behavioral researcher John B. Calhoun built a perfect world for mice. Unlimited food, unlimited water, no predators, no disease. Paradise. The mice thrived at first. They bred, built social groups, and formed a functioning colony. Then everything fell apart. Males became violent without reason. Females abandoned their young. A group Calhoun called the beautiful ones withdrew completely, spending their days grooming themselves in isolation while their world crumbled around them. Reproduction stopped. Social bonds dissolved. Every single mouse died.

Britain’s most famous mathematician takes us to the edge of knowledge to show us what we cannot know. Is the universe infinite? Do we know what happened before the Big Bang? Where is human consciousness located in the brain? And are there more undiscovered particles out there, beyond the Higgs...

Our brains evolved to solve the survival problems of our Stone Age ancestors, so when faced with modern-day situations that are less extreme, they often encounter a mismatch. Our primitive brains put us on the wrong foot by responding to stimuli that - in prehistoric times - would have prompted behaviour that was beneficial. If you've ever felt an anxious fight-or-flight response to a presenting at a board meeting, equivalent to facing imminent death by sabre-toothed tiger, then you have experienced a mismatch.

Myth-shattering social scientist Brian Klaas dives deeply into the phenomenon of random chance and the chaos it can sow, taking aim at most people's neat and tidy storybook version of reality. The book's argument is that we willfully ignore a bewildering truth: but for a few small changes, our lives - and our societies - could be radically different. Offering an entirely new lens, Fluke explores how our world really works, driven by strange interactions and apparently random events.
