Since its 2009 launch, the Kepler satellite has discovered more than 2,000 exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, remarkable in their variety. 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.

Brian Clegg's acclaimed popular science book Inflight Science explored the science experienced on a plane flight. Interstellar Tours takes that concept and goes large. It takes the listener on a tour of our galaxy on the starship Endurance.

Bringing his cosmic perspective to civilization on Earth, Neil deGrasse Tyson, bestselling author of Astrophysics for People in a Hurry, shines new light on the crucial fault lines of our time–war, politics, religion, truth, beauty, gender, race, and tribalism–in a way that stimulates a...

What is time? Does it exist? Can it be stopped? Can time's arrow be reversed? Can we ever free ourselves from the seemingly inexorable flow of time? Chronos is a mystery, and not only for us: it was a mystery for our distant ancestors too. In this book, Guido Tonelli guides us along the path to...

The question "what came first?" has shaped human thought since its earliest stirrings, from theological first principles to the search for base reality in simulation theory. This demand for ultimate origins appears so natural that it goes unnoticed, like air supporting breath without announcing itself. But what if this demand contains a hidden error? Boris Kriger's groundbreaking work argues that for certain closed hierarchical structures, the question of primary foundation is not merely unanswered—it is unanswerable.

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock. 

FROM ONE OF THE MOST BRILLIANT MINDS OF OUR TIME COMES A BOOK THAT CLARIFIES HIS MOST IMPORTANT IDEAS Stephen Hawking’s worldwide bestseller A Brief History of Time remains a landmark volume in scientific writing. But for readers who have asked for a more accessible formulation of its key...

A lighthearted yet profound guide to the realms of higher consciousness and the ultimate nature of reality. Explains some of the most difficult concepts of physics and heightened consciousness in ways that are easily understood. Presents a model for the interaction of the universe and...

Read by the author, Harry Cliff. 'As fascinating as its title suggests . . . Cliff recounts with vivid clarity the stories of some of the most striking oddnesses that have lit up the landscape of modern physics.' – Philip Pullman Newly discovered strangenesses could transform our understanding...

The Earth, that trusty old spinning marble we call home, isn't a sphere at all. No, according to some, it is flat as a pancake (or a pizza, if we're being generous). Yet for thousands of people, this is reality – or at least their version of it. The Flat Earth phenomenon isn't new. It has ancient roots, woven into the cosmologies of civilizations long past. But what's fascinating is how, in a time when we can send rovers to Mars, carry pocket supercomputers, and live-stream cat videos from space stations, this belief has not only persisted but thrived.

The determination of stellar ages is crucial for the development of our understanding of the universe and for constraining theoretical models of galaxy formation and planetary system evolution. The ages of stars provide scientists with timescales to identify the relevant physical processes...

Quasars are the brightest sustained phenomena in the known universe—engines of light powered by supermassive black holes devouring matter at the centers of distant galaxies. But they are more than cosmic spectacles. Every beam of quasar light that crosses the universe accumulates an extraordinarily detailed record of the gas, matter, and structure it passes through. The intergalactic medium writes its autobiography in the spectra of quasars, using absorption lines as words and sightlines as sentences.

Can you ever truly experience your own death? Quantum physics says no. Everyone dies. But what if, from your own perspective, death is impossible to experience? Reality doesn't follow one timeline. Every quantum event creates branching worlds where all outcomes happen. You exist in branches where you survived—but not in branches where you died.

For a century, physicists and philosophers have treated quantum mechanics as an anomaly—a realm where particles tunnel through barriers, exist in multiple states at once, and refuse to reveal their properties until observed. The quantum world has been called bizarre, counterintuitive, and fundamentally strange. But what if this strangeness was never in the world at all? What if it was only ever in our expectations? Nothing Strange About Quantum Strangeness offers a radical reframing.

Brought to you by Penguin. If you met an alien, what might it be like? Ever since childhood, astrophysicist Neil deGrasse Tyson has wanted to be abducted by aliens. Here, he draws upon a lifetime’s fascination to explore the science of alien life – and to offer a practical guide to your...

This book explains why events in the world cannot always be understood as the result of separate things influencing one another locally. Starting from a well-established result in modern physics, it shows that some correlations observed in nature cannot be explained by assuming that each object carries its own independent properties and that all influence spreads step by step through space. The book examines the theorem that establishes this limit and the experiments that confirm it.

Originally published in 1926, The Russell Genero-Radiative Concept is a concise and provocative exposition of Walter Russell’s cyclic theory of continuous motion. In this rare work, Russell outlines a universe governed not by linear mechanics, but by rhythmic balance—where all matter, energy, and motion arise from the interplay of generative and radiative forces.

Reality is not what it seems. Not fixed. Not silent. Not separate from the one who observes it. Quantum experiments reveal seams in the world… places where information appears without traveling… where outcomes wait for attention… where time behaves like something far more flexible than a river. These seams form a doorway. A narrow line where darkness gives way to light… where the familiar dissolves into the possible… where a question becomes the beginning of understanding. This book does not claim answers. It offers a key. If you have ever sensed something beneath the surface… Step closer.
