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...

Los últimos descubrimientos sobre el cosmos explicados con sencillezy con una sola fórmula: E= mc2. Es raro el día en el que no aparezca una noticia en los medios de comunicación sobre algún hallazgo de la astrofísica. Exoplanetas, púlsares, agujeros negros, cuásares, Big Bang, universo...

From the celebrated scientist and bestselling author of Seven Brief Lessons on Physics comes a radical new vision of reality, mapping a watershed moment in both physics and philosophy. We are living in an age of scientific advancement on par with that of Copernicus, Galileo, and Newton: a period...

Wie war das eigentlich mit dem Urknall? Warum starben die Dinosaurier aus? Was wiegt die Erde? Und wie ist das überhaupt möglich – die Erde zu wiegen? Auf diese und viele weitere Fragen hat SPIEGEL-Bestsellerautor Bill Bryson in der Schule nie Antworten erhalten. Deshalb hat er sich selbst auf die Suche nach ihnen gemacht und eine atemberaubende Reise durch Raum und Zeit angetreten. Dabei entstand ein faktenreiches, kluges und äußerst vergnügliches Hörbuch über die Wunder der Welt– mit all dem Witz und Charme, die Bryson zu einem der beliebtesten Sachbuchautoren unserer Zeit gemacht haben!

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...

For half a century, cosmology has relied on two invisible ingredients to explain the universe: dark matter, a substance that has never been detected despite decades of experimental search, and dark energy, a repulsive force whose physical nature remains entirely unknown. Together, they are said to constitute ninety-five percent of the cosmos. The remaining five percent—ordinary atoms, light, everything we have ever touched or measured—is treated as a minor addendum to a universe made mostly of darkness. This textbook presents a different cosmology. It is not speculative.

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...

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.

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.

Pour retracer l'histoire du Système solaire, Alessandro Morbidelli suit cette règle de Sherlock Holmes : « lorsque vous avez éliminé l'impossible, ce qui reste, si improbable soit-il, est nécessairement la vérité. » En éliminant progressivement les hypothèses les plus simples (les planètes se sont formées sur leurs orbites actuelles) mais démenties par les observations (les orbites des petits corps sont alors inexplicables), Alessandro Morbidelli et ses collègues sont parvenus au « modèle de Nice » pour décrire les déplacements et perturbations des corps du Système solaire.

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.

Avez-vous déjà ressenti une profonde curiosité pour les mystères de l’Univers ? Vous êtes-vous demandé ce qui se trouve au-delà de ce que vos yeux peuvent voir, dans les profondeurs du cosmos ? Voulez-vous comprendre ces énigmes qui, pendant des décennies, ont défié même les esprits les plus brillants ?

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Along the way, they offer both a call for new physics and a riveting story of scientific debate.
