A radical new vision of reality from one of the great minds of our time, mapping a watershed moment in both physics and philosophy. “Carlo Rovelli is the best thinker out there articulating physics, philosophy, and literature. There simply are no scientists of his caliber who also are...

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!

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.

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.

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...

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.

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.

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.

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 ?

In virtually all fields of human endeavor, Classical Athens was so much at the forefront of dynamism and innovation that the products of its most brilliant minds remain not only influential but still relevant to this day. To the ancient Greeks, the cosmos was ordered and harmonious. Consequently, reason and intellect were considered the architects of all art and craftsmanship. The absolute perfection of form was sought in everything and the Greek passion for simplicity, elegance, harmony, and beauty is to be found everywhere, particularly in architecture.

You are cosmically insignificant. You've heard it a thousand times. A pale blue dot. A speck of dust in an infinite void. A brief flicker between two eternities of darkness. This book says: that's wrong. Not sentimentally wrong. Mathematically wrong. Using rigorous information theory, fixed-point mathematics, and the concept of effective complexity developed by Nobel laureate Murray Gell-Mann, The Tiny Giants demonstrates that observers—biological and artificial—contribute a staggering share of the universe's meaningful structure.

What if reality is not a branching forest of infinite timelines, but a single, irreplaceable world whose value becomes clearer the moment we strip away seductive myths? This book confronts one of the most persistent modern fantasies—the idea of parallel universes—by examining it through science, philosophy, and the psychology of human perception. It exposes how easily speculative models slip into pseudoscience, how cultural repetition creates the illusion of credibility, and how misused scientific language blurs the boundary between rigorous inquiry and imaginative fiction.

Where do you go to let your curiosity fly? The backyard, of course. The setting for this audio original program is the backyard of William Shatner’s Los Angeles home, where he and Neil deGrasse Tyson enjoy a powerful, open-hearted conversation steeped in wonder. Having become fast friends and verbal sparring partners, the two men discuss the quest for knowledge that has driven human exploration and discovery over centuries, drawing from historical and contemporary examples.
